Chapter 3 - System Design Page 3-1 REV. 5 CHAPTER III SYSTEM DESIGN GENERAL The KITCHEN KNIGHT II Restaurant Fire Suppression System may be used on a number of different types of restaurant cooking appliances and hood and duct configurations. The design information listed in this section deals with the limita- tions and parameters of this pre-engineered system. Those individuals responsible for the design of the KITCHEN KNIGHT II system must be trained and hold a current PYRO-CHEM certificate in a KITCHEN KNIGHT II training program. NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity for duct, plenum, and appliance protection. Duct Protection It is not required that the fan be shut down or the exhaust duct be dampered for the system to operate properly. All duct protection is UL listed without limitation of maximum duct length (unlimited length). This includes all varieties of ductworks both horizontal and vertical including ducts that run at angles to the horizontal and ducts with directional bends. Duct protection requires that a nozzle be positioned to discharge into the duct. Two nozzles are available for duct protection. The Model IL Nozzle, Part No. 551026, is a one (1) flow nozzle. A single IL nozzle is capable of protecting square or rectangular ducts with a maximum perimeter of 50 in. (127 cm) (maximum side of 16 3/4 in. (42.6 cm)), with the diagonal being a maximum of 18 3/4 in. (47.6 cm). It can also protect a round duct with a maximum diameter of 16 in. (40.6 cm). The Model 2D duct nozzle, Part No. 551038, is a two (2) flow nozzle. A single 2D nozzle is capable of protecting square or rectangular ducts with a maximum perimeter of 100 in. (254 cm), with the diagonal being a maximum of 37 3/8 in. (94.9 cm). It can also protect a round duct with a maximum diameter of 31 7/8 in. (81 cm). When two (2) 2D duct nozzles are used to protect a single duct, the cross sectional area of the duct must be divided into two equal symmetrical areas. The nozzle must then be installed on the centerline of the area it protects and aimed directly into the duct opening. The nozzle(s) must be installed on the centerline of the duct, with the tip located 0 to 6 in. (15.2 cm) into the opening, and aimed directly into the duct opening. See Figure 3-1. In installations where a UL listed damper assembly is employed, the duct nozzle can be installed beyond the 6 in. (15.2 cm) maximum, to a point just beyond the damper assem- bly that will not interfere with the damper. Exceeding the maxi- mum of 6 in. (15.2 cm) in this way will not void the UL listing of the system. 0-6 IN. INTO DUCT IL OR 20 NOZZLE I/2 j1 006 172PC L Figure 3-1.

Example: The duct to be protected has a Side "A" of 40 in. and a Side "B" of 60 in. Referring to the design chart, this duct requires 4 nozzles. One half of 4 = 2. Therefore, 2 nozzles must be equally positioned in each of the two duct areas. See s. Figure 3-1a. SIDE "B" 30 IN. (76 cm) 30 IN. (76 cm) Chapter 3 - System Design Page 3-2 REV. 4 In.

PYRO- CHEM KITCHEN KNIGHT II recommends that transition ducts be protected as follows: a. Transition ducts - larger to smaller In cases where the duct/plenum interface opening is larger than the final exhaust duct, measure the perime- ter/diameter of the duct halfway between the largest and smallest section (or the average perimeter/diameter). The nozzle is to be located within 0-6 in. (15.2 cm) of the duct/plenum interface (not at the point where the measurement was taken), centered under the final exhaust duct opening. See Figure 3-1b. Note: Nozzles to protect ducts with a transition that is more than 4 ft (1.2 m) in height, will be required to be positioned in the opening of the transition from the hood 2 to 8 in. (5.1 to 20.3 cm) into the opening using standard duct nozzle design parameters. c. Multiple risers In cases of multiple rises, each riser is protected as an individual duct. See Figure 3-1d. P. Figure 3-1d. Electrostatic Precipitator - Ducts utilizing electrostatic precipitators must be protected above and below the unit. Standard duct nozzles are used in this application. See Figure 3-le. P. [ 006 173PC Figure 3-1e. p. Figure 3-1b. Plenum Protection b. Transition ducts - smaller to larger In cases where the duct/plenum interface opening is smaller than the final exhaust duct, measure the perime- ter/diameter of the final exhaust duct. The nozzle(s) is to be located within 0-6 in. (15.2 cm) of the duct/plenum p. interface, centered in the opening. See Figure 3-1c. The Model 1H nozzle, Part No. 551029, is a one (1) flow nozzle used for plenum protection. A single 1 H nozzle can protect a plenum (with single or V-bank filters) 10 ft (3.1 m) long by 4 ft (1.2 m) wide. Dividing the length into sections equal to or less than 10 ft (3.1 m) in length and positioning a nozzle at the start of each section can be done to protect longer plenums. PERP MEA5 Figure 3-1c. ULEX 3830 December 1, 2009 P. 208 Chapter 3 - System Design Page 3-4 REV. 3 On V-bank plenums, the nozzle(s) must be located at the center of the V-bank width, 1/3 of the vertical height of the filters. On single filter bank plenums, the nozzle must be located 2 in. (5.1 cm) from the back edge of the filter, 1/3 down from the vertical height. For either application, the nozzle must be located within 6 in. (15.2 cm) of the end of the plenum (or module) and aimed directly down the length of the plenum. The nozzles may point in the opposite directions as long as the entire plenum area is protected, and the 10 ft (3.1 m) limitation is not exceeded. See Figure 3-2.

(5085 sq cm) maximum, 28 in. (71 cm) longest side maximum) One nozzle is available for large range protection: High proximity. The Model 2L nozzle, Part No. 551027, is used for high proximity large range protection. This nozzle is a two (2) flow nozzle. When using high proximity protection, the range cannot be under a backshelf. This nozzle must be located 34 in. to 48 in. (86 to 122 cm) above the cooking surface, and aimed directly down within the mounting area, based on the hazard size, as described in the Nozzle Positioning Chart. See Figure 3-5. K 006411 Figure 3-5. Example: A four burner range has a hazard size of 20 in. (51 cm) in length and 27 in. (69 cm) in width. Follow down the Range Length column in the Nozzle Positioning Chart until you come to 20 in. (51 cm). Continue down this column until the correct width appears in the width column. When the width of 27 in. (69 cm) is arrived at, read across to the radius column to determine the size of radius allowed, for positioning of the nozzle, from the hazard area centerline. In this example, the correct radius is 3 in. (8 cm) The nozzle can be aimed straight down anywhere within a 3 in. (8 cm) radius of the hazard area centerline.

Tilt Skillet/Braising Pan Protection for tilt skillet or braising pans is to be based upon the coverage limitations provided for deep fat fryer protection. Coverage limitations are based on fryer sizes including drip boards. Exception: Tilt skillets and braising pans may exceed the maximum of 6 sq ft (0.6 sq m) total when modularizing. Tilt skillets and braising pans generally utilize a hinged cover. Fryer protection nozzles are to be placed toward the front of the appliance to minimize the potential for the tilt skillet or braising pan cover to interfere with the nozzle discharge. See Figure 3-17. THE NOZZLE IS TO BE PLACED TOWARD THE FRONT OF THE APPLIANCE TO MINIMIZE THE POTENTIAL FOR THE SKILLET OR BRAISING PAN COVER TO INTERFERE WITH THE NOZZLE DISCHARGE.

Each module must not exceed the maxi- mum area allowed for a single nozzle. However, when utilizing multiple nozzle protection, the longest side allowed for a fryer with drip board can be used, regardless of whether the fryer has a drip board or not. The maximum size fryer that can be modularized is 864 sq in. (5574 sq cm). Design requirements for multiple nozzle fryers are broken down as follows: If the fryer includes any dripboard areas, measure both the internal length (front to back) and width of the frypot portion. Then measure the internal length and width of the overall hazard area including any dripboard areas. Determine the area of both the frypot and the area of the overall vat by multiplying corresponding length and width dimensions. Divide the frypot or overall vat into modules, each of which can be protected by a single nozzle, based on the maxi- mum dimension and area coverage of the nozzle as speci- fied in "Design Chart." If the module considered does not include any portion of the dripboard, use only the maximum frypot area and maximum dimension listed in the "Design Chart." If the module considered includes any dripboard areas, use both the maximum frypot area and dimension listed in the "Design Chart', and the maximum overall area and dimension listed in the "Design Chart." 3. None of the maximum dimensions may be exceeded. If either the maximum frypot or the overall sizes are exceeded, the area divided into modules will need to be redefined with the possibility of an additional nozzle.

This section contains the guidelines and limitations for designing the distribution piping so that the wet chemical agent will discharge from the nozzles at a proper flow rate. These limitations must also be referred to when selecting the mounting location for the tanks. The maximum pipe lengths are based on internal pipe volume. Each size tank is allowed a minimum and maximum total volume of piping, calculated in milliliters. There is no need to distinguish between what portion of the piping is supply line and what portion is branch line. Only the total volume of the complete piping network has to be consid- ered. Volume Chart 1/4 in. pipe = 20.5 mIs/ft 3/8 in. pipe = 37.5 mIs/ft 1/2 in. pipe = 59.8 mIs/ft 3/4 in. pipe = 105.0 mIs/ft Tank Chart *Maximum Volume Allowed Maximum Between First Maximum Pipe Nozzle and Tank Flow Volume Last Nozzle Size Numbers (milliliters) (milliliters) 1.6 Gallon 5 1500 600 PCL-160 3.0 Gallon 10 1910 1125 PCL-300 4.6 Gallon 14 3400 3000 PCL-460 4.6 Gallon 15 2600 2000 PCL-460 6.0 Gallon 19 4215 1688 PCL-600 per side 6.0 Gallon 20 3465 1313 PCL-600 per side * All piping, including nozzle drops, must be included in the . piping calculations.

PCL-600 systems must use split piping only, with no nozzle located before the split, and with a maximum of 14 flow points per side. 1/2 in. minimum piping must be used up to the first split. Maximum volume for 1/4 in. pipe between a nozzle and the preceding tee is 410 mIs. Maximum flow numbers for 1/4 in. pipe is 6. Maximum number of elbows between a nozzle and the preceding tee is 5. Maximum of 25 elbows are allowed in the total piping system. Maximum difference in elevation between the tank outlet and any nozzle, or the tank outlet and the highest or lowest horizontal pipe run, is 10 ft (3.1 m). B. No traps are allowed in the piping network. Pipe lengths are measured from center to center of fittings. The internal equivalent length volume of fittings does not have to be considered as part of the total pipe volume. When utilizing different size pipe in the system, the largest size must start first and the additional pipe must decrease as it approaches the nozzle. Elbow(s) or swivel adaptors located at the nozzles do not have to be counted in the 25 elbow maxi- mum requirement. Reducing bushings are allowed when reducing to a smaller pipe size. Additional piping requirements when protecting a range, wok, or a fryer: PCL-160 - Minimum of 239 ml and one (1) flow number required in total system. Of that minimum, 180 ml must be utilized at or before the range, wok, or fryer. PCL-300 - Minimum of 300 ml and four (4) flow numbers required in total system. Of that mini- mum, 239 ml and two (2) flow numbers must be utilized at or before the range, wok, or fryer. PCL-460 - Minimum of 660 ml and ten (10) flow numbers required in total system. Of that mini- mum, 180 ml and two (2) flow numbers must be utilized at or before the range, wok, or fryer. PCL-600 - Minimum of 960 ml and fourteen (14) flow numbers required in total system. Of that minimum, 120 ml and 2 flow numbers must be utilized at or before the range, wok, or fryer. STRAIGHT PIPING -1p. Figure 3-18. Design Steps Step No. 1 Determine number of flow points required based on duct size, plenum size and type, and size of all appliances. Step No. 2 Determine size and quantity of tanks required. Refer to the chart in "General Piping Requirements" to determine the maximum amount of flow numbers allowed per each tank size. Step No. 3 Layout nozzles, piping diagram, and tank location. Determine pipe lengths as accurate as possible. Make certain maximum number of elbows is not exceeded. Note: Tanks cannot be manifolded together. Each tank must have a separate piping network. Step No. 4 Add all the lengths of each pipe run and multiply by the mis/ft. listed in the Volume Chart. If the sum falls within the acceptable range noted in general Piping Requirements, that pipe size is acceptable. If the calculated volume is too large, recalculate the volume using the ml per foot of a smaller pipe size. Pipe sizes can be mixed but Rule No. 11 of the General Piping Requirements must be followed. Step No. 5 Check to make certain minimum volumes, maxi- mum volumes and maximum volume allowed between first nozzle and last nozzle is not exceeded (Tank Chart). Check each rule in "General Piping Requirement" to make certain none have been exceeded. If any requirement is exceeded, change to a different pipe size and recalculate.

Chapter 1 - General Information Page 1-1 REV. 5 CHAPTER I GENERAL INFORMATION INTRODUCTION This manual is intended for use with PYRO-CHEM® KITCHEN KNIGHT® II Restaurant Fire Suppression Systems. Those who install, operate, recharge, or maintain these fire suppression systems should read this entire manual. Specific sections will be of particular interest depending upon one's responsibilities. Design, installation, recharge, and maintenance of the system must conform to the limitations detailed in this manual and performed by an individual who attended a PYRO-CHEM training program and became trained to install, recharge, design, and maintain the PYRO-CHEM: system. Fire suppression systems are mechanical devices. They need periodic care. Maintenance is a vital step in the perfor- mance of your fire suppression system. As such, it must be performed in accordance with NFPA 96 (Standard for the Installation of Equipment for the Removal of Smoke and Grease-Laden Vapors from Commercial Cooking Equipment) and NFPA 17A (Standard on Wet Chemical Extinguishing Systems) by an authorized PYRO-CHEM distributor. To provide maximum assurance that the fire suppression system will operate effectively and safely, maintenance must be conducted at six-month intervals, or earlier if the situation dictates. Twelve-year maintenance must include agent tank hydrostatic testing. The PYRO-CHEM KITCHEN KNIGHT II Pre-Engineered System utilizes a wet chemical agent specifically designed to suppress restaurant cooking area fires. The system provides automatic actuation and can be manually actuated through a remote mechanical pull station. Upon actuation, the system discharges a pre-determined amount of agent to the duct, plenum, and cooking appliances. The agent acts to suppress fires in three ways: The chemical chain reaction causing combustion is inter- rupted by both the agent itself and the resulting steam formation. The agent cools the fire bringing it below auto-ignition temperature. The agent reacts with hot grease forming a soap-like layer (saponification) that helps prevent the escape of combustible vapors, thus preventing re-ignition. The shutdown of all sources of fuel and electric power that produce heat to all equipment protected by the system is required upon system actuation. Make up or supply air fans, integral to the exhaust hood(s) being protected, shall be shut down upon system actuation. Exhaust fan(s) in the ventila- tion system should remain on during system discharge as they assist the dispersion of chemical through the ventilating system. The system is UL Listed with or without exhaust fan shutdown. The KITCHEN KNIGHT II and the KITCHEN KNIGHT Restaurant Fire Suppression System are compatible as long as separate installation guidelines are followed per each system design manual. Exception: The actuation limitations for the KITCHEN KNIGHT II system may be utilized for the KITCHEN KNIGHT system. Also, control heads, prior to Model No. 3, may be utilized on KITCHEN KNIGHT II systems, provided that the limitations used with those control heads are followed. Temperature Limitations The operating temperature range of the PYRO-CHEM KITCHEN KNIGHT II System is 32° F (00 C) minimum to 120° F (49° C) maximum.

The design information listed in this section deals with the limita- tions and parameters of this pre-engineered system. Those individuals responsible for the design of the KITCHEN KNIGHT II system must be trained and hold a current PYRO-CHEM certificate in a KITCHEN KNIGHT II training program. NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity for duct, plenum, and appliance protection. Duct Protection It is not required that the fan be shut down or the exhaust duct be dampered for the system to operate properly. All duct protection is UL listed without limitation of maximum duct length (unlimited length). This includes all varieties of ductworks both horizontal and vertical including ducts that run at angles to the horizontal and ducts with directional bends. Duct protection requires that a nozzle be positioned to discharge into the duct. Two nozzles are available for duct protection. The Model IL Nozzle, Part No. 551026, is a one (1) flow nozzle. A single IL nozzle is capable of protecting square or rectangular ducts with a maximum perimeter of 50 in. (127 cm) (maximum side of 16 3/4 in. (42.6 cm)), with the diagonal being a maximum of 18 3/4 in. (47.6 cm). It can also protect a round duct with a maximum diameter of 16 in. (40.6 cm). The Model 2D duct nozzle, Part No. 551038, is a two (2) flow nozzle. A single 2D nozzle is capable of protecting square or rectangular ducts with a maximum perimeter of 100 in. (254 cm), with the diagonal being a maximum of 37 3/8 in. (94.9 cm). It can also protect a round duct with a maximum diameter of 31 7/8 in. (81 cm). When two (2) 2D duct nozzles are used to protect a single duct, the cross sectional area of the duct must be divided into two equal symmetrical areas. The nozzle must then be installed on the centerline of the area it protects and aimed directly into the duct opening. The nozzle(s) must be installed on the centerline of the duct, with the tip located 0 to 6 in. (15.2 cm) into the opening, and aimed directly into the duct opening. See Figure 3-1. In installations where a UL listed damper assembly is employed, the duct nozzle can be installed beyond the 6 in. (15.2 cm) maximum, to a point just beyond the damper assem- bly that will not interfere with the damper. Exceeding the maxi- mum of 6 in. (15.2 cm) in this way will not void the UL listing of the system. 0-6 IN.

(254 cm) PERMETER Ducts over 100 in. perimeter must be modularized using 2D nozzles (Part No. 551038) No round duct option available Follow the design chart to determine maximum module size for each 2D nozzle When determining number of nozzles required, it is some- times an advantage to check the chart using the shortest side as Side "A" and then recheck it using the longest side as Side "A". This comparison may reveal a need for a lesser quantity of nozzles one way versus the other way. When working with Chart 1, the quantity of nozzles determined must be equally divided within the duct area. CHART NO.1 B A ... _ When working with Chart 2, one half of the quantity of nozzles determined must be equally positioned in the top half of the area of the duct and the remaining half of the nozzles must be positioned in the bottom half of the duct area. Example: The duct to be protected has a Side "A" of 40 in. and a Side "B" of 60 in. Referring to the design chart, this duct requires 4 nozzles. One half of 4 = 2. Therefore, 2 nozzles must be equally positioned in each of the two duct areas. See m. Figure 3-la. SIDE "B" 30 IN. (76 cm) 30 IN. (76 cm) 20 IN. I (51 cm) I I SIDE I 40 IN.

PYRO CHEM KITCHEN KNIGHT II recommends that transition ducts be protected as follows: a. Transition ducts - larger to smaller In cases where the duct/plenum interface opening is larger than the final exhaust duct, measure the perime- ter/diameter of the duct halfway between the largest and smallest section (or the average perimeter/diameter). The nozzle is to be located within 0-6 in. (15.2 cm) of the duct/plenum interface (not at the point where the measurement was taken), centered under the final exhaust duct opening. See Figure 3-1b. Note: Nozzles to protect ducts with a transition that is more than 4 f (1.2 m) in height, will be required to be positioned in the opening of the transition from the hood 2 to 8 in. (5.1 to 20.3 cm) into the opening using standard duct nozzle design parameters. c. Multiple risers In cases of multiple rises, each riser is protected as an individual duct. See Figure 3-1d. PLENUM Figure 3-1d. Electrostatic Precipitator - Ducts utilizing electrostatic precipitators must be protected above and below the unit. Standard duct nozzles are used in this application. See Figure 3-1e. 006 173PC P. Figure 3-1e. Figure 3-1b. b. Transition ducts - smaller to larger In cases where the duct/plenum interface opening is smaller than the final exhaust duct, measure the perime- ter/diameter of the final exhaust duct. The nozzle(s) is to be located within 0-6 in. (15.2 cm) of the duct/plenum interface, centered in the opening. See Figure 3-1c. Plenum Protection The Model 1 H nozzle, Part No. 551029, is a one (1) flow nozzle used for plenum protection. A single 1H nozzle can protect a plenum (with single or V-bank filters) 10 ft (3.1 m) long by 4 ft (1.2 m) wide. Dividing the length into sections equal to or less than 10 ft (3.1 m) in length and positioning a nozzle at the start of each section can be done to protect longer plenums. PERE MEAS Figure 3-1c. ULEX 3830 December 1, 2009 P. 10FT(3.1 m) MAXIMUM 000207 208 Chapter 3 - System Design Page 3-4 REV. 3 On V-bank plenums, the nozzle(s) must be located at the center of the V-bank width, 1/3 of the vertical height of the filters. On single filter bank plenums, the nozzle must be located 2 in. (5.1 cm) from the back edge of the filter, 1/3 down from the vertical height. For either application, the nozzle must be located within 6 in. (15.2 cm) of the end of the plenum (or module) and aimed directly down the length of the plenum. The nozzles may point in the opposite directions as long as the entire plenum area is protected, and the 10 ft (3.1 m) limitation is not exceeded. See Figure 3-2. Appliance Protection Note: When protecting appliances which are larger than single nozzle coverage, multiple nozzles can be used. Larger appliances can be divided into several modules, each equal to or smaller than single nozzle coverage. Exception: Fryers must not exceed a maximum of 864 sq in. (5574 sq cm).

(33 to 61 cm) above cooking surface, and aimed at a point one half the distance of whatever the height dimension of the nozzle is. When determining nozzle and aim point locations, both measurements are to be taken from the same end of the hazard area. Example: The nozzle is mounted 20 in. (51 cm) above the cooking surface. The aim point from the ecge of the hazard would then be 10 in. (25 cm) which is one half the nozzle mounting height dimension. See Figure 3-4a. Note: Nozzles must be placed at or below the shelf, within the nozzle height limitations. EDGE OF HAZARD AREA (FRONT OR BACK) 4 22 IN. (56cm) 1L I \I / F 22 IN. / 24 (56 cm) IL IN.

(71 cm) longest side maximum) One nozzle is available for large range protection: High proximity. The Model 2L nozzle, Part No. 551027, is used for high proximity large range protection. This nozzle is a two (2) flow nozzle. When using high proximity protection, the range cannot be under a backshelf. This nozzle must be located 34 in. to 48 in. (86 to 122 cm) above the cooking surface, and aimed directly down within the mounting area, based on the hazard size, as described in the Nozzle Positioning Chart. See Figure 3-5. K 006411 Figure 3-5. Example: A four burner range has a hazard size of 20 in. (51 cm) in length and 27 in. (69 cm) in width. Follow down the Range Length column in the Nozzle Positioning Chart until you come to 20 in. (51 cm). Continue down this column until the correct width appears in the width column. When the width of 27 in. (69 cm) is arrived at, read across to the radius column to determine the size of radius allowed, for positioning of the nozzle, from the hazard area centerline. In this example, the correct radius is 3 in. (8 cm). The nozzle can be aimed straight down anywhere within a 3 in. (8 cm) radius of the hazard area centerline.

Tilt Skillet/Braising Pan Protection for tilt skillet or braising pans is to be based upon the coverage limitations provided for deep fat fryer protection. Coverage limitations are based on fryer sizes including drip boards. Exception: Tilt skillets and braising pans may exceed the maximum of 6 sq ft (0.6 sq m) total when modularizing. Tilt skillets and braising pans generally utilize a hinged cover. Fryer protection nozzles are to be placed toward the front of the appliance to minimize the potential for the tilt skillet or braising pan cover to interfere with the nozzle discharge.

Each module must not exceed the maxi- mum area allowed for a single nozzle. However, when utilizing multiple nozzle protection, the longest side allowed for a fryer with drip board can be used, regardless of whether the fryer has a drip board or not. The maximum size fryer that can be modularized is 864 sq in. (5574 sq cm). Design requirements for multiple nozzle fryers are broken down as follows: If the fryer includes any dripboard areas, measure both the internal length (front to back) and width of the frypot portion. Then measure the internal length and width of the overall hazard area including any dripboard areas. Determine the area of both the frypot and the area of the overall vat by multiplying corresponding length and width dimensions. Divide the frypot or overall vat into modules, each of which can be protected by a single nozzle, based on the maxi- mum dimension and area coverage of the nozzle as speci- fied in "Design Chart." If the module considered does not include any portion of the dripboard, use only the maximum frypot area and maximum dimension listed in the 'Design Chart." If the module considered includes any dripboard areas, use both the maximum frypot area and dimension listed in the "Design Chart", and the maximum overall area and dimension listed in the "Design Chart." 3. None of the maximum dimensions may be exceeded. If either the maximum frypot or the overall sizes are exceeded, the area divided into modules will need to be redefined with the possibility of an additional nozzle.

This section contains the guidelines and limitations for designing the distribution piping so that the wet chemical agent will discharge from the nozzles at a proper flow rate. These limitations must also be referred to when selecting the mounting location for the tanks. The maximum pipe lengths are based on internal pipe volume. Each size tank is allowed a minimum and maximum total volume of piping, calculated in milliliters. There is no need to distinguish between what portion of the piping is supply line and what portion is branch line. Only the total volume of the complete piping network has to be consid- ered.

PCL-600 systems must use split piping only, with no nozzle located before the split, and with a maximum of 14 flow points per side. 1/2 in. minimum piping must be used up to the first split. Maximum volume for 1/4 in. pipe between a nozzle and the preceding tee is 410 mIs. Maximum flow numbers for 1/4 in. pipe is 6. Maximum number of elbows between a nozzle and the preceding tee is 5. Maximum of 25 elbows are allowed in the total piping system. Maximum difference in elevation between the tank outlet and any nozzle, or the tank outlet and the highest or lowest horizontal pipe run, is 10 ft (3.1 m). No traps are allowed in the piping network. Pipe lengths are measured from center to center of fillings. The internal equivalent length volume of fittings does not have to be considered as part of the total pipe volume. When utilizing different size pipe in the system, the largest size must start first and the additional pipe must decrease as it approaches the nozzle. Elbow(s) or swivel adaptors located at the nozzles do not have to be counted in the 25 elbow maxi- mum requirement. Reducing bushings are allowed when reducing to a smaller pipe size. Additional piping requirements when protecting a range, wok, or a fryer: PCL-160 - Minimum of 239 ml and one (1) flow number required in total system. Of that minimum, 180 ml must be utilized at or before the range, wok, or fryer. PCL-300 - Minimum of 300 ml and four (4) flow numbers required in total system. Of that mini- mum, 239 ml and two (2) flow numbers must be utilized at or before the range, wok, or fryer. PCL-460 - Minimum of 660 ml and ten (10) flow numbers required in total system. Of that mini- mum, 180 ml and two (2) flow numbers must be utilized at or before the range, wok, or fryer. PCL-600 - Minimum of 960 ml and fourteen (14) flow numbers required in total system. Of that minimum, 120 ml and 2 flow numbers must be utilized at or before the range, wok, or fryer. STRAIGHT PIPING 006 19 1PC Figure 3-18.

Exhaust Duct(s). Each exhaust duct must have at least one (1) detector installed in the duct entrance, located in the air stream of the cooking vapors at a maximum of 12 ft (3.7 m) into the duct. See Figure 3-23. Figure 3-23. 006884PC NOTICE When gas appliances are used and the flue gases from the burner are exhausted into the duct, the detector must be kept out of the air stream of these exhaust gases. These gases can be very hot and could actuate the system unnecessarily. Duct openings that are long and narrow or large enough to require multiple duct nozzles may require additional detectors. Electrostatic Precipitator. If an electrostatic precipitator is located at or near the base of the exhaust duct, it is necessary to locate a detector below the precipitator, at the base of the duct, and also locate one in the duct, just above the precipitator. See Figure 3-23a. When installing the detector bracket and system conduit, make certain they do not interfere with the operation of the precipitator. Figure 3-23a. 000265 ULEX 3830 December 1, 2009 Chapter 3 - System Design Page 3-20 REV. 2 Cooking Appliance(s). Each cooking appliance with a continuous cooking surface not exceeding 48 in. x 48 in. (122 x 122 cm) shall be protected by one (1) detector. Cooking appliances with a continuous cook- ing surface exceeding 48 in. x 48 in. (122 x 122 cm) shall be protected by one (1) detector per 48 in. x 48 in. (122 x 122 cm) cooking area. Detectors used for cooking appliances must be located above the protected appliance toward the exhaust duct side of the appliance. The detector should be located in the air stream of the appliance to enhance system response time. If the cooking appliance is located under an exhaust duct where a detector has been mounted, it is normally not necessary to utilize another detector for that cooking appliance, provided the detector is not more than 12 in. (30 cm) into the duct and the appliance has no larger cooking surface than 48 in. x 48 in. (121.9 cm 129.1 cm). See Figure 3-24. Note: If two (2) appliances are located under a duct opening where a detector has been mounted and both appliances together do not exceed a cooking surface of 48 in. x 48 in. (121.9 cm x 121.9 cm) and the detector is located above both the protected appliances, it is not necessary to utilize an addi- tional detector provided the duct detector is not more than 12 in. (30.5 cm) into the duct opening. APPLIANCE REQUIRES SEPARATE DETECTOR APPLIANCE COVERED BY DETECTOR UNDER DUCT APPLIANCE REQUIRES SEPARATE DETECTOR Figure 3-24.

ULEX 3830 December 1, 2009 Chapter 4 - System Installation Page 4-1 REV. 4 CHAPTER IV SYSTEM INSTALLATION GENERAL The installation information listed in this section deals with the limitations and parameters of this pre-engineered system. Those individuals responsible for the installation of the KITCHEN KNIGHT II system must be trained and hold a current PYRO-CHEM certificate in a KITCHEN KNIGHT II ,.training program. Pipe and fittings for the discharge piping, conduit (EMT), pipe straps, pipe hangers, mounting bolts, and other miscellaneous equipment are not furnished as part of the PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System. These items must be furnished by the installer. Before attempting any installation, unpack the entire system and check that all necessary parts are on hand. Inspect parts for damage. Verify that cylinder pressure is within the accept- able range as shown on the gauge. CYLINDER INSTALLATION The cylinder and valve assembly is shipped with an anti-recoil plug in the valve discharge port. CAUTION The anti-recoil plug must remain in the valve discharge port until the discharge piping is connected to the valve. The cylinder must be mounted vertically. The Models PCL-300 and PCL-460 cylinders must be mounted using a Model MB-15 Mounting Bracket Kit. The Model PCL-600 cylinder must be mounted using a Model MB-1 Mounting Bracket Kit. The bracket must be securely anchored to the wall using bolts or lag screws. The wall to which the bracket is attached must be sufficiently strong to support the cylinder. The bracket should never be fastened to dry wall or similar material. If this type of wall is encountered, studs must be located and the bracket fastened to them.

Multiple Cylinder Actuation Using MCH3/ECH3/NMCH3 Control Head The Model MCH3/ECH3/NMCH3 Control Head can be used to pneumatically actuate a maximum of five (5) agent cylinders with a 16 gram CO2 cartridge. When a control head is used for multiple cylinder actuation, it cannot be mounted directly onto a cylinder valve. The control head must be installed remotely using a Model MB-P2 Control Head Mounting Bracket. The bracket must be anchored to the wall using bolts or lag screws. CAUTION Do not screw the control head directly to a wall as this will warp the control head, not allowing the mechanism to actuate. In order to actuate the agent cylinder(s) from a control head, a 1/4 in. NPT x 450 1/4 in. flare type fitting (conforming to SAE J513c) or male straight connector (Part No. 32338) must be screwed into the base of the control head actuator. Pneumatic tubing or stainless steel actuation hose is then used to connect the control head to the valve cap assembly of each agent cylinder valve. See Figure 4-3. NOTE Pneumatic tubing (copper) used for remote cylinder actuation shall have an outside diameter of 1/4 in. with a minimum wall thickness of 1/32 in. This is commonly known as refrigeration-type copper tubing. All tubing fittings shall be of the 1/4 in., 45° flare type conforming to SAE J513c. Compression type fittings are not acceptable. A single Model MCH3/ECH3/NMCH3 Control Head can actuate: Up to four (4) cylinders with a maximum of 25 ft (7.6 m) of copper or stainless steel pneumatic tubing or stainless steel actuation hose when using an 0-ring (PN 55531) installed in place of the Teflon washer and the 16 gram CO2 cartridge.

See Figure 4-5a. If a PAC-lo cylinder is not utilized, there is a maximum of 25 ft (7.6 m) of tubing for the two control heads and up to 4 cylinders or a maximum of 18 ft (5.4 m) of tubing for the two control heads and 5 cylinders. DETECTOR INSTALLATION Fusible Link Detection Fusible links are always used in conjunction with the Model MCH3 Mechanical Control Head. After mounting the cylinder and control head, the fusible link line can be installed. The first step to installing the fusible link line is to install the detector bracket(s) over all protected appliances and in each duct. See Chapter III for detector placement guidelines. Note: Only ML-style Fusible Links can be used. Connect the fusible link brackets together using 1/2 in. conduit and the conduit connectors supplied in the detector kit (Model FLK-1). A PYRO-CHEM KITCHEN KNIGHT II corner pulley must be used whenever a change in conduit direction is neces- sary. The conduit is connected to the control head through a knockout in the upper left-side corner. In general, fusible links centered in the detector brackets are connected in series using 1/16 in. diameter stainless steel cable. The spring plate in the control head maintains tension on this series of fusible links. If the tension is released for any reason (i.e., a fusible link separates), the control head will operate and actuate the system.

Fusible Link Line Limitations When Used with Model EN-MCU3, MCH3, and NMCH3 Control Heads and CBP-1, SBP-1, and WBP-1 Pulley Elbows Maximum # of detectors: 20 Maximum length of cable: 150 ft (45.7 m) Maximum # of pulleys: 40 Fusible Links Without Hangers Begin installing links at the terminal bracket. The link is connected to the far side of the terminal bracket using an "S' hook. The "S' hook must be crimped closed after the link is installed. A tight loop is then made in the cable and secured by the crimp provided. This loop is connected to the other side of the terminal link (see Figure 4-6) and the cable fed through the conduit to the next bracket. The cable proceeding from the terminal link will be used to connect the series links (see Figure 4-7). Series links must be centered in their detector brackets. After the last link in the series is connected, the cable should be fed through the conduit back to the control head. Thread the cable through the hole in the fusible link ratchet wheel. The line must then be crimped, and the crimp positioned inside the center of the ratchet wheel. NOTE Crimps must always be used in conjunction with two (2) cable lengths. Loops are the accepted method of connecting the cable to mechanical components. The crimp must never be used on a single cable. Exception: Single cable crimp allowed in detection and gas valve ratchet wheel using stop sleeve, Part No. 26317 (Packages of 10: Part No. 24919). The fusible link line can now be put into a set position by applying tension to the fusible link line. This is accomplished by using a 1/2 in. hex wrench on the fusible link line ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direc- tion until the spring plate makes contact with the top of the control head box. The fusible link line is now in a set position.

This is easily accomplished before any tension is applied to the link line. Repeat this procedure for all fusible links. After the last hanger/link in the series is connected, the cable should be fed through the hole in the fusible link ratchet wheel. The line must then be crimped, and the crimp positioned inside the center of the ratchet wheel. NOTE Crimps must always be used in conjunction with two (2) cable lengths. Loops are the accepted method of connecting the cable to mechanical components. The crimp must never be used on a single cable.

LATCHING ARM SPRING PLATE Chapter 4 - System Installation Page 4-7 REV. 4 SETTING THE CONTROL HEAD Model MCH3/NMCH3 Mechanical Control Head Once the fusible link line is set, the control head can be placed in the set position. Set the control head using the proper procedure of ratcheting the detection line to raise the spring plate parallel to the top of the control head box prior to placing the latching arm in the slide plate. The slide plate is moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide plate. Continue moving the slide plate to the left until the latching arm is in the locked posi- tion. Insert the pull pin into the hole in the slide plate above the latching arm. This will lock the control head in the set position, eliminating accidental actuation during the rest of the installa- tion procedure. See Figure 4-13. Model ECH3 Electrical Control Head Once the thermal detectors have been installed, the control head can be placed in the set position. To set the control head, the slide plate is moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide plate. Continue moving the slide plate to the left until the latch- ing arm is in the locked position. Insert the pull pin into the hole in the slide plate above the latching arm. This will lock the control head in the set position, eliminating accidental actua- tion during the rest of the installation procedure. Once the Model ECH3 Electrical Control Head is in the set position, it can be connected to the detection/actuation circuit. CAUTION Before working on any electrical wiring, make certain main power has been disconnected. Failure to discon- nect main power could cause personal injury or death if contact is made with energized wires.

Connect the other side of the first thermal detec- tor in series and the remaining black wire on the solenoid in the control head to the appropriate power source after installing the Model SM-120 Solenoid Monitor. CAUTION The solenoid must never be wired 'hot" (not through the electrical (snap-action) switch). If wired this way, the non- field replaceable solenoid will be damaged and the complete control head will require replacement. NOTE A Model SM-120 Solenoid Monitor must always be used with an Electrical Control Head to supervise the actuation/detection circuit. Where electrical detection and/or actuation is provided, supervision shall be provided in accordance with NFPA-17A. Alarms and indicators along with a supervised backup power source shall be provided in accordance with NFPA 72, The National Fire Alarm Code. Electrical wiring and equipment shall be installed in accordance with NFPA 70, National Electric Code or the requirements of the authority having jurisdiction. The Model ECH3-24 Electrical Control Head requires a 24VDC power supply with a minimum 2A rating. The Model ECH3-120 Electrical Control Head requires a 1A, 120VAC power supply. ULEX 3830 December 1, 2009 SOLENOID MONITOR INSTALLATION Solenoid Monitor Installation in Detection Circuit After installing the thermal detectors and the control head, the Model SM-120 Solenoid Monitor can be installed. The Solenoid Monitor is connected to the wires leading from the last thermal detector. It should be mounted in a location where it can be readily observed. The Solenoid Monitor is an end-of-line device that supervises the actuation/detection circuit. It is comprised of a push-type switch with a built-in indicator light, a plug-type relay, a relay socket, and a cover plate. The light, when illuminated, indi- cates that the detection/actuation circuit is in the normal condition. The Solenoid Monitor also provides two sets of dry contacts. The Solenoid Monitor's cover plate is used to mount the Solenoid Monitor in a standard 6 in. x 4 in. x 3 in. (15 x 10 x 8 cm) deep electrical box. See Figure 4-14. Figure 4-14.

All gas valve installation and testing shall be made in accordance with the authority having jurisdiction. CAUTION To reduce the risk of explosion due to leaking gas, make certain that the gas line is turned off before connecting the gas valve. Mechanical Gas Shut-off Valve Installation TEMPERATURE LIMITATIONS: Maximum ambient and fluid temperature is 120 °F (49 °C). POSITIONING: Valve may be mounted in any position. PIPING: CAUTION To prevent damage to valve, DO NOT OVER-TIGHTEN PIPE CONNECTIONS. Connect piping to valve in accor- dance with markings on valve body. Pipe compound should be applied to male pipe threads only. When tight- ening pipe, do not use valve as a lever. To avoid strain on valve, assure all piping is aligned and supported properly. STRAINER INSTALLATION: For the protection of the gas valve, install a strainer or suitable filter in the inlet piping, as close to the gas valve as possible. Periodic cleaning of strain- ers recommended. PREVENTIVE MAINTENANCE: Keep medium flowing through valve as free from foreign material as possible. Keep valve filter/strainer clean. IMPROPER OPERATION: Incorrect Pressure: Pressure to valve must be within range specified on nameplate. Leakage: If leakage is detected, contact an authorized PYRO-CHEM distributor immediately. The Model MCH3/NMCH3 Control Head is used to operate the mechanical gas shut-off valve. This valve is located in the fuel gas supply line to the cooking appliance(s). The valve body has an arrow which indicates direction of gas flow through the valve. The gas shut-off valve is spring loaded and requires five pounds of force to hold it open. This force is supplied by a 1/16 in. diameter stainless steel cable that is connected to the control head. After the valve is installed in the gas line, 1/2 in. conduit must be run from the top center knockout of the gas valve box to the lower right-hand knockout in the control head. A PYRO-CHEM KITCHEN KNIGHT II corner pulley is used wherever a change in conduit direction is required. Gas Valve Cable Run Limitations When Used with Model MCH3, EN-MCU3, and NMCH3 Control Heads and CBP-1, SBP-1, and WBP-1 Pulley Elbows Maximum length of cable: 100 ft (30.5 m) Maximum # of pulleys: 30 Remove the gas valve cover and thread the stainless steel cable through the conduit back to the control head. Thread the cable through the hole in the gas valve ratchet wheel. The line must then be crimped, and the crimp positioned inside the center of the ratchet wheel. NOTE Crimps must always be used in conjunction with two (2) cable lengths. Loops are the accepted method of connecting the cable to mechanical components. The crimp must never be used on a single cable. Exception: Single cable crimp allowed in detection and gas valve ratchet wheel using stop sleeve, Part No. 26317 (Packages of 10: Part No. 24919). At the gas valve, loop the cable through the valve stem and secure it with the crimp provided (see Figure 4-18). Figure 4-18. Gas Valve Installation. 002886PC CAUTION Do not over-tension wire rope going from control head to gas valve at gas valve ratchet wheel. Over-tensioning may cause the valve to not close properly, resulting in the fuel supply not completely shutting off. The gas valve line can now be put into a set position by apply- ing tension to the gas valve line. This is accomplished by using a 1/2 in. hex wrench on the gas valve ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the gas valve is fully open. See Instruction Sheet, Part No. 550571, included in gas valve shipping assembly, for detailed informa- tion. Secure the gas valve cover plate to the gas valve box with the four (4) screws provided.

PULLEY TEE INSTALLATION The Pulley Tee is used to connect two (2) mechanical gas valves or two (2) remote mechanical pull stations to a single control head. The cable proceeding from the control head must always enter the branch of the pulley tee. See Figure 4-20. m. A pulley tee that is used to close two (2) gas valves can only be used to close gas valves with similar stem travel. Gas valves from 3/4 in. up to 1 1/2 in. can be used on the same P. pulley tee. A 2 in. gas valve can be used only with another 2 in. gas valve. Gas valves from 2 1/2 in. up to 3 in. can be used on P. the same pulley tee. As an example, using a 3/4 in. gas valve with a 3 in. gas valve will not allow the 3 in. valve to fully open. CAUTION The pulley tee must never be used to connect multiple fusible link lines to a single control head. ELECTRICAL (SNAP-ACTION) SWITCH INSTALLATION See NFPA 72, 'National Fire Alarm Code," Initiating Devices section, for the correct method of wiring connection to the fire alarm panel.

The following procedures must be followed: Use Schedule 40 black iron, chrome-plated, or stainless steel pipe and fittings. Do not use hot-dipped galvanized iron pipe or fittings in the agent distribution piping. Before assembling the pipe and fittings, make certain all ends are carefully reamed and blown clear of chips and scale. Inside of pipe and fittings must be free of oil and dirt. The distribution piping and fitting connections, located in the hood or the protected area, must be sealed with pipe tape. When applying pipe tape, start at the second male thread and wrap the tape (two turns maximum) clockwise around the threads, away from the pipe opening. Do not over-tighten, but be sure the pipe is snug. Do not back-off sections of pipe to make them fit better. If the pipe was cut too short, re-cut another pipe to the proper length. CAUTION Do not apply Teflon tape to cover or overlap the pipe opening, as the pipe and nozzles could become blocked and prevent the proper flow of agent. Do not use thread sealant or pipe joint compound.

Model MCH3/NMCH3 Mechanical Control Head Before putting the system into service, all components must be checked for proper operation. During this checkout, assure that the carbon dioxide pilot cartridge is not installed in the control head actuator. Remove the pull pin from the hole in the slide plate. To check satisfactory operation of the control head, cut the terminal link or the 'S" hook holding the link. This will relieve all tension on the fusible link line and operate the control head. The slide plate will move fully to the right. The gas valve cable will be released, causing the gas valve to close. Any auxiliary equipment connected to the dry contacts of the solenoid monitor and/or the Electrical (Snap-Action) Switch in the control head will operate. If any of these events fail to occur, the problem must be inves- tigated and repaired. Repair the terminal link and put the fusible link line back into the set position. This is accomplished by using a 1/2 in. hex wrench on the fusible link line ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the spring plate makes contact with the top of the control head box. Once the fusible link line is set (note: Refer to page 4-4 through 4-6 for fusible link installation details), the control head can be placed in the set position. To set the control head, the slide plate is moved from right to left, ensuring the bolt extend- ing from the cam arm is in the slot provided in the slide plate. Continue moving the slide plate to the left until the latching arm is in the locked position. Once the control head is set, pull the pull handle on the remote pull station to assure that the control head operates. If the control head operates normally, the control head can be reset as described above. Insert the pull pin into the hole in the slide plate above the latching arm. Replace the pull station handle, pull pin, and nylon tie. Assure that the gas valve is fully open by ratcheting the gas valve ratchet wheel. CAUTION Before screwing the 16 gram carbon dioxide pilot cartridge into the actuator, ensure that the actuator has an 0-ring washer installed. Using a felt-tipped marker, write the date of installation on the carbon dioxide pilot cartridge. Screw the cartridge into the control head actuator until hand-tight. Never use a wrench to tighten the cartridge into the actuator. Remove the pull pin from the hole in the slide plate and install the control head cover. Insert the pull pin through the local manual control handle and into the bushing. Secure the pull pin with the nylon tie provided. 2. Model ECH3-24/120 Electrical Control Head. Before putting the system into service, all components must be checked for proper operation. During this checkout, assure that the CO2 pilot cartridge is not installed in the control head actu- ator. Remove the pull pin from the hole in the slide plate. CAUTION Make certain to remove the CO2 cartridge. Failure to do so during testing will result in system actuation. Testing Thermal Detectors Remove the electric control head cover. Test each detector individually and reset control panel and recock release mechanism after each test. (Refer to proper AUTOPULSE control panel reset instructions). Using a heat gun positioned approximately 12 in. from the detector, apply heat to the detector for about one minute. Overheating will cause damage to the detector. Applying heat to the detector will cause the control head to operate or will cause the AUTOPULSE control panel to go into an alarm condition, and activate the control head. When the control head operates, the following will take place: a) The slide plate will move fully to the right; b) The indicator light on the solenoid monitor will go out; and c) Any auxiliary equipment connected to the dry contacts of the solenoid monitor and/or the snap-action switch in the control head will operate. If any of these events fail to occur, the prob- lem must be investigated and repaired. After all the thermal detectors have cooled, the AUTOPULSE control panel can be reset (refer to proper AUTOPULSE control panel reset instructions) and the control head can be placed in the set position. To set the control head, the slide plate must be moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide plate. Continue moving the slide plate to the left until the latching arm is in the locked posi- tion. ULEX 3830 December 1, 2009 Chapter 4 - System Installation U Page 4-16 REV. 5 Testing Remote Pull Station Once the control head is set, pull the pull handle on the remote pull station to assure that the control head oper- ates. If the control head operates normally, the control head can be reset as described in Step 4 above. Insert the pull pin into the hole in the slide plate above the latching arm. Replace the pull station handle, pull pin, and break rod Completing System Checkout - 1. Make certain the AUTOPULSE control panel is reset and the control head is re-cocked and set. If the Model SM-i 20 Solenoid Monitor is used instead of an AUTOPULSE control panel, energize the actuation/detection circuit by depressing the push button on the solenoid monitor. Using a felt-tipped marker, write the date of installation on the CO2 pilot cartridge. Ensure that the actuator has an 0-ring installed, and screw the cartridge into the control head actuator until hand tight.

Models EN-MCU3 and EN-S Enclosures. 002946PC Chapter 4 - System Installation Page 4-17 REV. 3 Fusible Link Detector Installation The Model EN-MCU3 Enclosure can support a fusible link detection system. The Model EN-S Enclosure cannot support a fusible link detection system and must be used in conjunction with the Model EN-MCU3 Enclosure or a Model MCH3/ECH3/NMCH3 Control Head. After mounting the enclosure, the fusible link line can be installed. The first step to installing the fusible link line is to install the detector brackets. These brackets must be installed in the plenum area of the ventilation hood over all protected appliances and in each duct. See Chapter III for detector placement guidelines. Connect the fusible link brackets together using 1/2 in. EMT conduit and the conduit connectors supplied in the detector kit (Model FLK-1/1A). PYRO-CHEM KITCHEN KNIGHT II corner pulleys must be used whenever a change in conduit direction is necessary. The conduit is connected to the enclosure through a top knockout. See Fusible Link Detector Installation Section of this chapter (pages 4-4 - 4-7) for fusible link installation guidelines. Before attaching the stainless steel cable to the fusible link line ratchet wheel, it must be run below the fusible link line pulley in the enclosure. See Figure 4-32. To Remote Fusible Link Pull Station Pulley /Ratchet eel Fusible Link Figure 4-32. Model EN-MCU3 Fusible Link Line and Remote Pull Station Termination. 002947PC Setting the Model EN-MCU3 After the last link in the series is connected, the cable should be fed through the conduit back to the Model EN-MCU3. It must be fed under the fusible link line pulley and through the hole in the fusible link ratchet wheel. The line must then be crimped, and the crimp positioned inside the ratchet wheel. NOTE Crimps must always be used in conjunction with two (2) cable lengths. Loops are the accepted method of connecting the cable to mechanical components. The crimp must never be used on a single cable. Exception: Single cable crimp allowed in detection and gas valve ratchet wheel using stop sleeve, Part No. 26317 (Packages of 10: Part No. 24919). The fusible link line can now be put into a set position by tensioning the fusible link line. This is accomplished by using a 1/2 in. hex wrench on the fusible link line ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the spring plate is parallel to the top of the enclosure. The fusible link line is now in a set position. Once the fusible link line is set, the Model EN-MCU3 Enclosure can be placed in the set position. To set the Model EN-MC(J3, the slide plate is moved from right to left, ensuring the bolt extending from the cam arm is in the slot provided in the slide plate. Continue moving the slide plate to the left until the latching arm is in the locked position. Insert the pull pin into the hole in the slide plate above the latching arm. This will lock the control mechanism in the set position, eliminating acciden- tal actuation during the rest of the installation procedure. See Figure 4-32. Remote Pull Station Installation The Model RPS-M Remote Mechanical Pull Station is used for remote manual actuation of the Model EN-MCU3 It is to be located near an exit in the path of egress from the hazard. Height and location of pull station should be determined in accordance with the Authority Having Jurisdiction. The Pull Station is connected to the Model EN-MCU3 using 1/16 in. diameter stainless steel cable. The cable enters the Model EN-MCU3 through a knockout in the top of the enclo- sure. See Figure 4-32. See Remote Pull Station Installation Section of this chapter for remote pull station installation guidelines. ULEX 3830 December 1, 2009 Chapter 4 - System Installation Page 4-18 REV. 5 Gas Shut-off Valve Installation The Model EN-MCU3 can be used to operate a mechanical gas shut-off valve. This valve is located in the fuel gas supply line to the cooking appliance(s). The valve body has an arrow which indicates direction of gas flow through the valve. The gas shut-off valve is spring loaded and requires five pounds of force to hold it open. This force is supplied by a 1/16 in. diame- ter stainless steel cable that is connected to the Model EN- MCU3. See 'Gas Shut-off Valve Installation" (page 4-11) section of this chapter for gas valve shut-off installation guidelines. After the valve is installed in the gas line, 1/2 in. conduit must be run from the top center knockout of the gas valve box to the P. top or bottom knockout in the enclosure. See Figure 4-31. A PYRO-CHEM KITCHEN KNIGHT II corner pulley is used wher- ever a change in conduit direction is required. Remove the gas valve cover and thread the stainless steel cable through the conduit back to the Model EN-MCU3. If the cable enters the enclosure through the bottom knockout, the cable must be run over the gas valve line pulley (see Figure 4- 33). If the cable enters the enclosure through the top knockout, the cable must be run under the gas valve line pulley (see Figure 4-34). Thread the cable through the hole in the gas valve ratchet wheel. The line must then be crimped, and the crimp positioned inside the center of the ratchet wheel. CAUTION The gas valve cable must always utilize the gas valve pulley and exit the top or bottom of the enclosure. The gas valve cable cannot exit the side of the enclosure. At the gas valve, loop the cable through the valve stem and secure it with the crimp provided (see Figure 4-18, page 4-11). The gas valve line can now be put into a set position by apply- ing tension to the gas valve line. This is accomplished by using a 1/2 in. hex wrench on the gas valve ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the gas valve is fully open. Secure the gas valve cover plate to the gas valve box with the four (4) screws provided. The gas valve line m. is now in a set position. See Figure 4-33 and/or Figure 4-34. CAUTION Do not over-tension wire rope going from control head to gas valve at gas valve ratchet wheel. Over-tensioning may cause the valve to not close properly, resulting in the fuel supply not completely shutting off.

During this checkout, assure that the carbon dioxide pilot cartridge is not installed in the Model EN-MCU3 actuator. Remove the pull pin from the hole in the slide plate. To check satisfactory operation of the control mechanism, cut the terminal link or the 'S" hook holding the link. This will relieve all tension on the fusible link line and operate the control mechanism. The slide plate will move fully to the right. The gas valve cable will be released, causing the gas valve to close. Any auxiliary equipment connected to the dry contacts of the solenoid monitor and/or the Electrical (Snap-Action) Switch in the Model EN-MCU3 will operate. If any of these events fail to occur, the problem must be inves- tigated and repaired. Repair the terminal link and put the fusible link line back into the set position. This is accomplished by using a 1/2 in. hex wrench on the fusible link line ratchet wheel. The ratchet wheel will be ratcheted in a clockwise direction until the spring plate is parallel to the top of the enclosure.

Replace the pull station handle, pull pin, and nylon tie. To test the thermal detectors, use a heat gun. Hold the gun approximately 12 in. (30.5 cm) from the detector for about one minute. Do not overheat. Overheating can cause damage to detector. Allow detector to cool after testing. Assure that the gas valve is fully open by ratcheting the gas valve ratchet wheel. Do not overtighten. CAUTION Before screwing the 16 gram carbon dioxide pilot cartridge into the actuator, ensure that the actuator has an 0-ring washer installed. Using a felt-tipped marker, write the date of installation on the carbon dioxide pilot cartridge. Screw the cartridge into the Model EN-MCU3 actuator until hand-tight. Install cartridge per the following: a. It is recommended that the cartridges first be fully hand tightened and then further tightened 1/4 to 3/4 turn using a needle-nose Vise-Grips. Note: Use caution not to damage cartridge with Vise-Grips. Note 1: 4 to 5 threads should be showing when the cartridge is engaged properly. It is important that no more than 5 threads be showing. Note 2: The cartridge and 0-ring shall be replaced annually. CAUTION Do not over-tighten cartridge. Over-tightening can result in premature puncturing of the cartridge seal. Remove the pull pin from the hole in the slide plate. Secure the Model EN-MCU3 or EN-S cover with the screws provided. Figure 4-35. Single Cylinder Installation with Figure 4-36.

ULEX 3830 December 1, 2009 Chapter 4 - System Installation Page 4-21 FLEXIBLE CONDUIT INSTALLATION Flexible conduit allows for quicker installations and the conve- nience of being able to route the cable over, under, and around obstacles. Flexible conduit is designed for use with PYRO-CHEM® restaurant systems. Flexible conduit can be used as a substi- tute for standard EMT conduit or can be used with EMT conduit. Flexible conduit CANNOT be used in detection systems. Design Requirements Prior to starting the flexible conduit installation, the detection system must be complete and attached to the control head. Flexible conduit cannot be utilized in detection systems. Flexible conduit inserts, Part No. 434347, can ONLY be used with the flexible conduit system. The maximum distance from a PYRO-CHEM control head to a mechanical pull station is 140 ft (42.7 m) with a maximum of 3601 (for example, 3-90° and 2-45° bends, 2-90° and 4- 45° bends, etc.) bends in the flexible conduit, one pulley tee (Refer to Design, Installation Manual for detailed splicing instructions), two splices, and 15 pulley tees. Note: When installing flexible conduit, make sure to feed wire rope through conduit directly from the spool of wire rope. DO NOT pre-cut wire rope. Feeding pre-cut rope through flexible conduit will cause excessive kinks in the rope, making it diffi- cult to install. The maximum distance from a PYRO-CHEM control head to a mechanical gas valve is 75 ft (22.9 m) with a maximum of 4-90° bends in the flexible conduit and 4 pulley elbows. Any portion of the flexible conduit system can be substituted with EMT conduit provided the proper connections are used to join the two types of conduit. All bends in the flexible conduit system must have a mini- mum bend diameter of 6 in. (15 cm). When the flexible conduit is used to make 90° bends between a control head and a mechanical gas valve, the bends must start at the control head. No pulley elbows can be used between the bends. If more than 360° of bends are needed, then pulley elbows can be used. When the flexible conduit is used to make 90° bends between a control head and a pull station, the bends must start at the control head. No pulley elbows can be used between the bends. If more than 360° of bends are needed, then pulley elbows can be used. Only PYRO-CHEM pull stations utilizing a composite (black) bushing on the back side of the pull station cover can be used with flexible conduit. When not utilizing a conduit offset, Part No. 436063, 2-45° bends in the flexible conduit are allowed between the strain relief on top of the control head and the location where the flexible conduit is supported. Note: This is allowed on pull station installations only. When installing flexible conduit, conduit should be secured at intervals not to exceed 5 ft (1.5 m) and before and after each bend. Flexible conduit CANNOT slide in the clamp(s) used for mounting. Make certain mounting clamp(s) do not pinch the flexible conduit. The following style clamp ('P' clip), Part No. 436150, is a suitable type for use on flexible conduit.

Make certain stainless steel wire rope is clean and debris-free. The flexible conduit should be routed along the same path that EMT conduit would normally be run. Stainless steel wire rope should be routed through the flexible conduit as it is in EMT conduit. CAUTION Flexible conduit must not be located within 6 in. (15 cm) of the hood or in areas exceeding 130 °F (54 °C). Also, do not route flexible conduit in areas where conduit can be crushed, pinched, or broken.

ULEX 3830 December 1, 2009 Chapter 5 - System Maintenance Page 5-1 REV. 5 CHAPTER V SYSTEM MAINTENANCE GENERAL The maintenance information listed in this section deals with the limitations and parameters of this pre-engineered system. Those individuals responsible for the maintenance of the KITCHEN KNIGHT II system must be trained and hold a current PYRO-CHEM certificate in a KITCHEN KNIGHT II training program. SEMI-ANNUAL MAINTENANCE Check that the hazard area has not changed. Check that the system has not been tampered with, i.e., nozzles removed, nozzles not aimed properly, piping not supported properly, blow off caps in place. Check the entire system for mechanical damage. Check all nozzle orifices to make certain they are not plugged. Replace blow off caps or 0-ring if necessary. Note: Rubber blow-off caps that have been installed in the system for one year or more must be replaced. Check the solenoid monitor. CAUTION Before continuing, remove the cover from the control head and insert the safety pin in the hole in the slide plate above the latching arm. This will secure the system, preventing accidental discharge. Disconnect the control head or pneumatic tubing from the valve cap assembly of each agent cylinder. Remove the carbon dioxide pilot cartridge in the control head. Remove the safety pin from the slide plate. Actuate the control head to ensure it is functioning properly. Make certain the gas shut-off valve and remote pull station are functioning properly. Inspect the pulley elbows for excessive grease buildup. Clean elbows if necessary. Replace fusible links. (They must be replaced semi-annually per NFPA 96.) Visually inspect thermal detectors. NOTE Methods and frequency of inspection, testing and maintenance of detectors should be in accordance with NFPA-72. Reinstall the carbon dioxide pilot cartridge, reconnect the control head, and replace the control head cover and nylon tie. See detailed cartridge installation instructions listed on Page 4-20 (System Installation). CAUTION Before screwing the carbon dioxide pilot cartridge into the actuator, ensure that the actuator has an 0-ring installed. If actuator is utilizing a Teflon washer, replace with 0-ring, Part No. 55531. Inspect the cylinder pressure. Tap the gauge lightly to ensure the needle is moving freely. If the gauge shows a loss in pressure indicated by the needle being below the green band, the tank should be removed and recharged per the SYSTEM RECHARGE section of Chapter VI (System Recharge) in this manual. ANNUAL MAINTENANCE Inspect as per semi-annual maintenance instructions. Do not reconnect control head at this time. Disconnect the discharge piping from the valve outlet. Using air or nitrogen, blow out the piping. Replace all nozzle caps. Fixed temperature sensing elements of the fuxible alloy type must be replaced, at a maximum semi-annually, or more frequently if necessary, to assure proper operation of the system. Test thermal detectors and remote pull stations per SYSTEM CHECKOUT AFTER INSTALLATION section located in Chapter IV (System Installation) of this manual. Per NFPA 72, two (2) or more detectors per circuit should be tested. Note individual detector location and date of testing. Within 5 years, all detectors in system must be tested. Replace the carbon dioxide pilot cartridge and 0-ring (Part No. 55531). Record the date of installation on the cartridge with a felt-tipped marker. See detailed cartridge installation instructions listed on Page 4-20 (System Installation). ULEX 3830 December 1, 2009 Chapter 5 - System Maintenance Page 5-2 REV. 2 CAUTION Before screwing the carbon dioxide pilot cartridge into the actuator, ensure that the actuator has an 0-ring installed. 8. Reconnect the control head. Replace the control head cover and nylon tie. 12-YEAR MAINTENANCE Along with the required annual maintenance requirements, the tanks must be removed from the system, properly discharged, and hydrostatically tested per the requirements of NFPA-1 7A. The tank should be refilled with fresh agent. NOTE Refer to the nameplate on tank for hydrostatic pres- sure requirements. ULEX 3830 December 1, 2009 Chapter 6 - System Recharge Page 6-1 REV. 5 CHAPTER VI SYSTEM RECHARGE GENERAL The recharge information listed in this section deals with the limitations and parameters of this pre-engineered system. Those individuals responsible for the recharge of the KITCHEN KNIGHT II system must be trained and hold a current PYRO-CHEM certificate in a KITCHEN KNIGHT II training program. SYSTEM CLEANUP CAUTION Before attempting any cleanup, make certain that all fuel sources to the equipment to be cleaned have been shut off. Make certain that the exhaust hood and all appliance electrical controls have been de-ener- gized to avoid any chance of electrical shock resulting from the cleaning process of electrically conductive alkaline liquid agent and/or its residue. Make certain all surfaces to be cleaned have cooled down to room temperature. Do not use water to clean any appliances that contain hot grease or cooking oils. Doing so may result in violent steaming and/or spattering. SYSTEM RECHARGE NOTE Determine the cause of system discharge and correct immediately before performing system recharge. After discharge, inspect the entire system for mechanical damage. If the tank has sustained any mechanical damage, it must be hydrostatically tested before refilling. Disconnect the 1/4 in. actuation tubing or the control head from the top of the tank valve. Relieve the pressure from the top chamber of the tank valve by depressing the core of the valve in the valve cap assembly. By performing this operation, the valve will close. 4. Slowly remove the valve and siphon tube. If there is any residual pressure left in the tank, it will bleed out through the pressure relief slot in the valve threads. 5. The complete piping system must be flushed after a discharge. Flushing concentrate, Part No. 79656, must be used when flushing the system. The concentrate is shipped in a 32 oz (0.95 L) container. A PCL-160 tank requires 1/2 of a container. A PCL-300 tank requires 1 container of concentrate. A PCL-460 requires 1 1/2 containers, and a PCL-600 requires 2 containers. To prepare the system for flushing: Pour the required amount of flushing concentrate into the tank. Fill the tank approximately half full with warm, clear water. Agitate the tank for a few seconds and then add more warm water to bring the level to the required fill line using the measuring stick, Part No. 551039. Reinstall valve and pickup tube. Hand tighten to 12.5 foot pounds maximum torque. CAUTION Do NOT use a wrench or other tool to tighten the valve. Do NOT use a pipe extension on the valve outlet for the purpose of providing additional torque. Pressurize tank to 225 psi (15.5 bar) at 70 °F (21 °C) and reinstall to piping network. 6. With nozzles in place, attach control head and manually actuate the tank. Allow the tank to completely discharge through the piping network. 7. After the discharge is completed, the entire piping network must be blown out with air or nitrogen until no more mist is visual coming out of the nozzles. 8. Remove, clean, and reinstall all nozzles. 9. Remove the tank from the system. Slowly remove the valve and siphon. If there is any residual pressure left in the tank, it will bleed out through the pressure relief slot in the valve threads. The valve and pressure regulator (located in outlet of valve) must be cleaned and rebuilt after each discharge. To rebuild the valve, use rebuilding kit, Part No. 550698. To rebuild the pressure regulator, use rebuilding kit, Part No. 551061. Each kit includes an instruction sheet listing detailed rebuilding instructions. 10. Fill tank with required amount of KITCHEN KNIGHT agent, Part No. 551188 (3 gal) or Part No. 553176 (1.6 gal), using measuring stick, Part No. 551039. Tank should be filled to a tolerance of —0/+118 in. (-01+0.3 cm) from the mark level on the measuring stick. ULEX 3830 December 1, 2009 Chapter 6 - System Recharge Page 6-2 REV. 3 NOTE During filling, the agent temperature should be 60 °F to 80°F (16°C to 27°C). NOTE The pressure gauge attached to the tank valve should not be used to determine when the charging pressure has been reached. A calibrated external gauge must be used. NOTE The pressure regulator in the valve outlet must be removed before pressurizing. Reinstall valve and pickup tube. Hand tighten to 12.5 foot pounds maximum torque. Pressurize Shrader valve assembly with 150 psi (10.3 bar) of nitrogen. Install recharge adaptor, Part No. 551240, into the valve outlet and pressurize with nitrogen to 225 psi (15.5 bar) at 70 °F (21 °C). Wait 10 minutes and verify the pressure in the tank is at 225 psi (15.5 bar). Relieve the pressure from the Shrader valve assembly (this will cause the valve to close) and then disconnect the recharge adap- tor. Reinstall pressure regulator into valve outlet. CAUTION If pressure is not relieved from Shrader valve assem- bly before the recharge adaptor is removed, the tank will discharge. Replace all fusible links by following the instructions listed in the Installation Section. Reset control head(s), accessories, pull stations and gas valves by following the instructions listed in the Installation Section.
