However, before attempting any installation, it is necessary to attend a Factory Certification Training Class and become Certified to design the PYRO-CHEM KITCHEN KNIGHT II Restaurant Fire Suppression System. The chapter is divided into three (3) sections: Nozzle Coverage and Placement • Piping Limitations • Detector Requirements Each of these sections must be completed before attempting any installation. NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity tor duct, plenum, and appli- ance 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), 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 20 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 Oto 6 in. (15.2 cm) into the opening, and aimed directly into the duct opening. See Figuie 3-1 a. 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 assembly that will not interfere with the damper. Exceeding the maximum of 6 in. (15.2 cm) in this way will not void the UL listing of the system.

(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 tor each 2 D 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 deter- mined must be equally divided within the duct area. CHART N0.1 B 25126 27128" ,,,,, JI I 32 "'" "'" 37138 391 «l 41142 .,, ...

Example:The duct to be protected has a Side "A" ol 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 Figure 3-1b. 49150 2 - 20 IN.

PY RO-CHEM KITCHEN KNIGHT II recommends that transi- tion ducts be protected as follows: a. Transition ducts -larger to smaller ln 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/diame- ter). 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 3-1c.

Plenum Protection 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 1 0 ft. (3.1 m) in length and positioning a nozzle at the start of each section can be done to protect longer plenums. ULEX 3830 March 1. 2006 Chapte, 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, 113 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 tilter, 113 down from the vertical height. For either application, the nozzle must be !ocated within 6 in. (15.2 cm) of the end of the plenum (or module) and aimed directly down the length of ►, the plenum. The nozzres 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.

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. It. (.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.

ULEX 3830 Marr.h 1 ?nn~ chapter 3 -System Design Page 3-14 REV. 4 Fryer -Multiple Nozzle Protection Fryers exceeding the coverage of a single nozzle can be divided into modules. Each module must not exceed the maximum 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: 1. 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 includirig any dripboard areas. Determine the area of both the frypot and the area of the overall vat by multiplying corresponding length and width dimensions. 2. Divide the frypot or overall vat into modules, each of which can· be protected by a single nozzle, based on the maximum dimension and area coverage of the nozzle as specified in ·oesign Chart." If the module considered does not include any portion of the dripboard, use only the maximum frypot area • and maximum dimension listE!d in the "Design Chart. u • If the module considered includes any dripboard areas, use both the maximum frypot area and dimen- sion listed in the "Design Charr, and the maximum overall area and dimension listed in the uoesign Chart." 3. None of the maximum dimensions may be exceeded. If either the maximum fryp0t or the overall sizes are • exceeded, the area divided into modules will need to be redefined with the possibility of an additional nozzle. !LEX 3830 larch 1, 2006 ► ► PIPING LIMITATIONS Once the nozzle placement and quantity of tanks has been determined, it is necessary to determine the piping configu- rations between the tank and the nozzles. 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 limi- tations 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 considered. Volume Chart 1 /4 in. pipe = 20.5 mis.If!. 3/8 in. pipe = 37.5 mls./ft. 1 /2 in. pipe = 59.8 mis.If!. 3/4 in. pipe= 105.0 mlslft.

Split piping and straight piping are both allowed ► on a PCL-160, PCL-300 and PCL-460 system. ► I ► ► 2. 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. mini- mum piping must be used up to the first split. 3. Maximum volume for 1/4 in. pipe between a nozzle and the preceding tee is 41 O mis. 4. Maximum flow numbers for 1/4 in. pipe is 6. 5. Maximum number of elbows between a nozzle and the preceding tee is 5. 6. Maximum of 25 elbows are allowed in the total piping system. 7. 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). 8. No traps are allowed in the piping network. 9. Pipe lengths are measured from center to center of fittings. 10. The internal equivalent length volume of fittings does not have to be considered as part of the total pipe volume. 11. When utilizing different size pipe in the system, the largest size must start first and the addi- tional pipe must decrease as it approaches the nozzle. 12. Elbow(s) or swivel adaptors located at the nozzles do not have to be counted in the 25 elbow maxi- mum requirement. 13. Reducing bushings are allowed when reducing to a smaller pipe size. 14. 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.

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 loca- tion. 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 multi- ply by the mlsJft. 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, re.calculate 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 v61umes, 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 recalcurate.

GEN, PIPING AULENO.12 DETECTOR PLACEMENT Detectors are required over cooking appliances and in the duct(s) of protected ventilation hoods. Detectors shall be located in the plenum area of the ventilation hood. 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 feet (3.7 m) into the duct. See Figure 3-23. 11 V ~ ---- . r " t====11 I - -- Figure 3-23. 006684PC NOTICE • s 12 FT. (3. 7m) M MAXIMU 11 - . 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 ·1n 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. r Figure 3-23a. """" Cooking Appliance(s) . Chapter 3 -System Design Page 3-19 REV. 2 Each cookin'g appliance with a continuous cooking suriace not exceeding 48 in. x 48 in. (122 x 122 cm) shall be protected by one (l) _detector. Cooking appliances with a continuous cooking 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 cook- ing appliances must be located above the protected appli- ance toward the exhaust duct side of the appliance. The detector should be ·Iacated in the air stream of the appliance to enhance. system response time . If a cooking appliance is located under a duct opening where a detector has been mounted, it is not necessary to utilize an additional detector provided the duct detector is not more than 12 in.
