Chapter 1 - General Information Page 1-1 REV. 5 CHAPTER I GENERAL INFORMATION INTRODUCTION This manual is intended for use with PYRO-CHEM® KITCHEN KNlGHTe 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. p-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 (490 C) maximum. UL Listing The PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System has been tested to the UL Standard for Fire Extinguishing Systems For Protection of Restaurant Cooking Areas.

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 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) 20 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. ULEX 3830 December 1 2009 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 2D NOZZLE H TW_Tw 4- 1/21 006172 PC L Figure 3-1.

(254 cm) PERIMETER 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 H • SIDE "B" 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 UAO of 40 in. and a Side BU 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 P. Figure 3-la. SIDE "B' 30 IN. (76 cm) 30 IN. (76 cm) 20 IN. I (51 cm) I SIDE I 40 IN.

Chapter 3 - System Design Page 3-3 REV.4 Transition Ducts - The protection of non-standard ducts should be reviewed by the authority having jurisdiction. PYRO- CHEM KITCHEN KNIGHT II recommends that transition ducts be protected as follows: 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 oper.ing. 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. PERIMETER -'-/- - - - MEASUREMENT I -, ) + _11- Figure 3-1b. 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.

Multiple risers In cases of multiple rises, each riser is protected as an individual duct. See 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 3-1 e. 20 NOZZLE PRECIPITATOR PLENUM 20 NOZZLE 006176PC Figure 3-1e. Plenum Protection The Model 1H nozzle, Part No. 551029, is 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. Y INTO ITION ULEX 3830 December 1, 2009 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 wkh, 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.

ULEX 3830 March 1, 2006 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).

This nozzle is a one (1) flow nozzle. The range can be equ"ped either with or without a back- shelf. Either type requires the same nozzle requirements. The nozzle must be located 22 in. (56 cm) from either end of the hazard area centered from left to right. It must be 13 in. to 24 in. (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 edge 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. 2a. High-Proximity Backshelf Protection - When using the 2L nozzle for range protection with high-proximity backshelf, the maximum length of burners being protected must not exceed 28 in. (71 cm) and the maximum area of the burners must not exceed 336 sq in. (2167 sq cm). The backshelf must be a minimum of 18 in. (45.7 cm) above the top of the range and may overhang the burner by a maximum of 11 in. (28 cm). Note: Although most shelves exceed 11 in. (28 cm) in overall depth, make sure the shelf does not exceed 11 in. (28 cm) overhang of the burner. Nozzle must be located on the front edge of the front burner and aimed at a point 10 in. (25 cm) forward from the back edge of the back burner on the front-to-rear centerline. Nozzle must be mounted 24 to 35 in. (61 - 89 cm) above the hazard surface. See Figure 3-4b.

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.

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 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 reqired 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 ooe'g,Pc Figure 3-18.

ULEX 3830 March 1, 2006 Chapter 3 - System Design Page 3-19 REV. 3 DETECTOR PLACEMENT Detectors are required over cooking appliances and in the duct(s) of protected ventilation hoods. 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. 0068MPG 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. 208 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. x48 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 x 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 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-i 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. See Figure 4-1. Figure 4-1. Cylinder and Mounting Bracket Installation. 002945PC CONTROL HEAD INSTALLATION Single Cylinder Installation For single cylinder system installations the Model MCH3/ECH3/NMCH3 Control Head can be installed directly onto the cylinder valve.

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. 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. Up to five (5) cylinders with a maximum of 18 ft (5.4 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. CAUTION Confirm the Teflon washer in the control head actuator assembly has been replaced with the 0-ring (PN 55531) and the 16 gram CO2 cartridge is installed for 4 and 5 cylinder single control head actuation. The actuation line must be tested for any leaks by using a hand held or electric vacuum pump. The pump should be used to draw a vacuum on the actuation line at the fitting closest to the control head. A vacuum should be pulled to 20 inches of mercury. Leaks exceeding 5 inches of mercury within 30 seconds are not allowed. If the gauge on the vacuum pump indicates a leak in the line, examine the actuation line for loose fittings or damage. Correct any leaks and retest. MCH3, NMcH3, OR ECH3 CONTROL HEAD 1/4 IN. OD COPPER TUBING OR S.S. ACTUATION HOSE MAX. 18 FT. (5.4 m) FOR 5 CYLINDER ACTUATION 1/4 IN. NPT X 45 1/4 IN.

If a PAC-lo cylinder is not utilized, there is a maximum of 25 it (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 I.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.

Agent Distribution Hose can only be used for castered appliances or appliances setting on castered supports. Chapter 4 - System Installation Page 4-14.1 r Installation Requirements Agent Distribution Hose must be connected to 3/8 in. NPT black iron, chrome-plated, or stainless steel fittings. The connection from hose to fitting requires a 1/2 in. x 3/8 in. reducing coupling. All Agent Distribution Hose connections must be sealed with pipe tape. When applying pipe tape, start at the second male thread on the swivel ends of the hose. Wrap the tape (two turns maximum) clockwise around the threads, away from the hose end fitting opening. All connections of distribution piping to Agent Distribution Hose for castered appliances, with distribution nozzles installed/affixed to the appliance, must be located behind the cooking equiprñent in an area protected from obstruc- tions and possible wear or damage. 3/8 in. schedule 40 pipe will need to be run from the hose connection to the distribution nozzle(s) installed/affixed to the appliance. Pipe must be installed and adequately secured at a height at or below the cooking surface of the appliance. See Figure 4-30. All existing distribution pipe and fitting limitations must be observed and followed. Each flex distribution hose used is to be considered as 300 ml when calculating the milliliters per system. All hose-to-pipe connection fittings are to be oriented in a vertical down position. The hose connections must be positioned below an eleva- tion where the hose could be exposed to the radiant or convected heat generated by normal cooking operations (such as the horizontal plane of appliance's cooking surface), or to heat from appliance exhaust. As a minimum height, the hose connection shall be no lower than 30 in.. (76.2 cm) from the floor. The distribution piping shall be supported and secured per local plumbing practices. Hose ends are to be offset 6 to 8 in. (15.2 to 20.3 cm) center to center of fittings (see Figure 1) to maximize hose life expectancy and facilitate appliance movement. With the appliance in its normal operating position, check the hose bend to make certain the bend is not less than a 3 in. (7.6 cm) bend radius (6 in. (15.2 cm) diameter).

ULEX 3830 December 1, 2009 Chaptr 4 - System Installation Page 4-14.4 (Page Intentionally Left Blank) ULEX 3830 December 1, 2009 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. 43 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. 4. 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. Chapter 4 - System Installation Page 4-15 REV.4 SYSTEM CHECKOUT AFTER INSTALLATION 1. 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. 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 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 Make certain the AUTOPULSE control panel is reset and the control head is re-cocked and set. If the Model SM-120 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. Continue installation of cartridge by turning an additional 1/4 turn using a wrench or pliers. Use caution not to damage cartridge. Note 1: 4 to 5 threads should be showing when the cartridge in engaged properly. It is important that no more than 5 threads be showing. Note 2: The cartridge and 0-ring shall be replaced annu- ally. 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 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 tie provided. NOTE Refer to NFPA-17A for additional inspection require- ments. ULEX 3830 December 1, 2009 ENCLOSURE INSTALLATION INSTRUCTIONS MODEL EN-MCU3 (PIN 551208) AND MODEL ENS (PIN 550966) Enclosure Mounting The Model EN-MCU3 and/or EN-S Enclosure must be securely anchored to the wall using bolts or lag screws. The wall to which the enclosure is attached must be sufficiently strong. The enclosure should never be fastened to dry wall or similar material. If this type of wall is encountered, studs must be located and the enclosure fastened to them. Three (3) center mounting holes allow either enclosure to be mounted on a single stud. Four (4) corner mounting holes are also available. See Figure 4-31.

Models EN-MCU3 and EN-S Enclosures. 00204upC 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 Fusible Link /Ratchet Wheel 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-MCU3, 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 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 s. 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. ULEX 3830 December 1, 2009 Figure 4-33.

All electrical connections must be made in an approved electrical box. Cylinder Installation Single Cylinder Installation - PCL-300/460 The Model EN-MCU3 can be used for single cylinder installa- tions. It can support either the Model PCL-300 or PCL-460 cylinder assemblies. The cylinder must be placed in the enclo- sure with the discharge port to the left. No additional mount- ing bracket is required when the Model EN-MCU3 is used. In order to actuate the agent cylinder from the Model EN-MCU3s control mechanism, pneumatic tubing must be used to connect the actuator to the valve cap assembly of the agent cylinder valve. A 1/8 in. NPT x 1/4 in., 45° flare type elbow is included and must be installed in the actuator of the Model EN-MCU3 Enclosure. See Figure 4-35. NOTE Pneumatic tubing (copper) used for cylinder actuation shall have an outside diameter of 1/4 in. (0.6 cm) with a minimum wall thickness of 1/32 in. (0.08 cm). This is commonly known as refrigeration-type copper tubing. All tubing fittings shall be of the 1/4 in., 450 flare type conforming to SAE J513c. Compression type fittings are not acceptable. Multiple Cylinder Installation - PCL-300/460 The Model EN-S can be used in conjunction with the Model EN-MCU3 Enclosure or Model MCH3/ECH3 Control Head for multiple cylinder installations. A single Model EN-MCU3 can be used to pneumatically actuate a maximum of five (5) agent cylinders with the 16 gram CO2 cartridge. One (1) agent cylin- der can be installed in the Model EN-MCU3 Enclosure; the additional agent cylinder(s) can either be mounted in a Model EN-S Enclosure or with a Model MB-is Mounting Bracket. When an enclosure is used, the cylinders must be placed in the enclosure(s) with the discharge port to the left. No addi- tional mounting bracket is required when a cylinder is installed in the Mode! EN-MCU3 or EN-S Enclosure. In order to actuate the agent cylinders from the Model EN-MCU3, pneumatic tubing must be used to connect the EN-MCU3 actuator to the valve cap assembly of each agent cylinder valve. Pneumatic tubing or stainless steel actuation hose must be run from the actuator in the Model EN-MCU3 to the Model EN-S(s) through the side knockouts. A 1/4 in., 45° flare x 1/4 in., 45° flare x 1/8 in. NPT tee is included with the Model EN-S and must be installed in the Model EN-MCU3 actuator. See Figure 4-36. NOTE Pneumatic tubing (copper) used for remote cylinder actu- ation shall have an outside diameter of 1/4 in. (0.6 cm) with a minimum wall thickness of 1/32 in. (0.08 cm). This is commonly known as refrigeration-type copper tubing. All tubing fittings shall be of the 1/4 in., 450 flare type conforming to SAE J513c. Compression type fittings are not acceptable. A single Model EN-MCU3 can actuate up to 4 cylinders with 25 ft. (7.6 m) of pneumatic tubing or stainless steel actuation hose or a maximum of five (5) cylinders with up to 18 ft. (5.4 m) of pneumatic tubing or stainless steel actuation hose. System Checkout After Installation 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 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. ULEX 3830 December 1, 2009 OO2SOPC END CYUNDER Chap'ter 4 - System Installation Page 4-20 Once the fusible link line is set, the control mechanism can be placed in the set position. To set the control mechanism, 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.

ULEX 3830 December 1, 2009 Chapter 4 - System Installation Page 4-21 r 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 3600 (for example, 3-90° and 2-45° bends, 2-90° and 4- 450 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 4-900 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 3600 of bends are needed, then pulley elbows can be used. When the flexible conduit is used to make 900 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 3600 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, 2-450 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-tree. 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 Figure 4-39. 008068 ULEX 3830 December 1, 2009 Char er 4 - System Installation Page 4-22 Flexible conduit can be used to connect a PYRO-CHEM control head to a remote pull station or mechanical gas valves. Before starting the system- installation, take a few minutes to plan the layout of the system. This will minimize the amount of components needed to complete the installation. Once the path of the flexible conduit has been determined, verify that the layout does not exceed the design requirements. Connecting the Flexible Conduit to the PYRO-CHEM Control Head, Electrical Box, Pull Station, or Mechanical Gas Valve 1. Layout the flexible conduit and secure it in place. Note: If inner liner is crimped, turn a drywall screw into the end to open it. See Figure 4-38. Figure 4-38. 007985 2. Starting at the PYRO-CHEM control head, connect the conduit connector using the supplied nut. Use only PYRO- CHEM conduit fittings, Part No. 55813. See Figure 4-39. 3. 3.
