Installation and maintenance of the system must conform to the limitations detailed in this manual and be performed by an'Authorized Pyro-Chem Kitchen Knight II dealer. The Pyro-Chem Kitchen Knight IISystem 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: 1.The chemical chain reaction causing combustion is interrupted by both the agent itself and the resulting steam formation. 2. The agent cools the fire bringing it below auto -ignition temperature. 3. 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 fuel and power to all appliances under protected ventilation equibment is required uoon system actuation. The shutdown of make-up or supply air is recommended upon system actuation but is not required. Exhaust fan(s) in the ventilation system should remain on during system discharge as they assist the dispersion of chemical through the ventilat- ing system. The system is UL Listed with or without exhaust fan shutdown. t TEMPERATURE LIMITATIONS The operating temperature ranae of the Pyro-Chem Kitchen Knight II System is 32° F. (0° C.) maximum. minimum to 120° F. (49° C.) 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 UL300 and Listed by Underwriters Laboratories. Inc. System agent cylinders bearing the Underwriters Laboratories of Canada. Inc. ULC mark also meet Underwriters Laboratories of Canada's Standard ULC/ORD-C1254.6-1995.

CHAPTER III SYSTEM DESIGN This section will cover the proper design of the Pyro-Chem w; Kitchen Knight II Restaurant Fire Suppression System. It is `divided -into three (3) sections: - Nozzle Coverage and Placement • Piping Limitations Detector Requirements — as IN. Each of these sections must be completed before attempting INTO DUCT any installation. 20 NO LE NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines for determining nozzle type, positioning, and quantity for duct, plenum, and appli- ance protection. A. Duct Protection It is not required that the fan be shut down or the exhaust duct be dampered for the system to operate properly. Each nozzle is approved to protect exhaust ducts of unlimited length. Duct protection requires that a nozzle by positioned to dis- charge up, into the duct. The nozzle is a Model 2D, Part No 551038. The Model 2D duct nozzle is a two (2) flow nozzle. A single 2D nozzle is capable of protecting square or rectangular duct with a maximum of 100 in. perimeter, with the loneest side being a maximum of 34 in. It can also protect a round duct with a maximum diameter of 31 7/8 in' Two (2) Model 2D duct nozzles can protect a square or rec- tangular duct with a maximum of 150 in. perimeter, with the longest side being a maximum of 51 in. They can also pro- tect a round duct with a maximum diameter of 47 1/2 in. 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 o in. into the opening, and aimed directly into the duct opening. See Figure 3-1. Chapter 3 System Design ., ..,,Page 3-1 112 w I i 1v2 L ----i I --•' Figure 3-1. 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: 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/diame- ter). The nozzle is to be located within -0-6 in. of the duct/plenum interface (not at the point where the mea- surement was taken). centered under the final exhaust duct opening.

Each module must not exceed the `maximum area allowed 'for a single nozzle. However, when utilizting'"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. Desidn 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 including any dripboard areas. Determine the area of both the frypot and the area of the overall vat by multiplying corresponding lenoth 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 "Desion 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 dimen- sion 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. ULEX 3470 October 1, 2001 PN551274 PIPING LIMITATIONS ,,once the nozzle placement'andquantity of tanks has.been determined-," it is necessary to determine the piping configu- rations between the tank and the nozzles. This section con- tains the guidelines and limitations for designing the distribu- tion 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 loca- tion for the tanks. The maximum pipe lengths are based on internal pipe vol- ume. Each size tank is allowed a minimum and maximum total volume of piping, calculated in milliliters. There is no need to distinouish 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./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.

Maximum volume for 1 4"in. pipe between a nozzle and the preceding tee is 410 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 pip- ing system. i 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 it. 8. No traps are allowed in the piping network. 9. Pipe lengths are measured, from center to center of fittings. 10. The internal equivalent leh'ath volume of fittings does not have to be considered as part of the total pipe volume. j 11. 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. l 12. Elbow(s) or swivel adaotors 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 requir2ments when protecting a range, wok. or a 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.

However, before attempting any installation it is necessary to attend a Factory Certification Training Class andbecome Certified to install the Pyro-Chem Kitchen Knight II Restaurant Fire Suppres- sion System. Because it is difficult to completely understand every aspect of an intricate pre-engineered system simply by reading the Technical Manual, Pyro-Chem Kitchen Knight II will not be responsible for system installations or mainte- nance performed by any non -Certified person(s). Pipe and fittings for the discharge piping, conduit (EMT), pipe straps, pipe hangers, mounting bolts, and other miscel- laneous equipment are not furnished as part of the Pyro-Chem Kitchen Knight II Restaurant Fire Suopression 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 acceptable 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.

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). These brackets must be installed in the plenum area of the ventilation hood over all protected appli- ances and ineachduct.See Chapter III for detector place- ment guidelines. Note: Only ML -style Fusible Links can be used. Connect the fusible link brackets together using 1/2" conduit and the conduit connectors supplied in the detector kit (Model FLK -1/1A). A Pyro-Chem Kitchen Knight II corner pulley must be used whenever a change in conduit direction is necessary. The conduit is connected to the control head throueh a knockout in the upper left -side corner. In general, fusible links centered in the detector brackets are connected in series using 1/16" 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. Maximum limitations for the fusible link detection line are as follows: Fusible links can be installed with or -without fusible link hangers (see Chapter II for description). l Fusible Link Line Limitations When Used with Model EN-MCU3, MCH3, and NMCH3 Control Heads and CSP -1, SBP -1, and WBP-1 Pulley Elbows Maximum # of detectors: 20 .Maximum length of cable: 150 feet Maximum # of pulleys: 40 1. Fusible Link Installation Without H.3naers. Begin installing links at the terminal bracket. The link is con- nected 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 proceed- ing 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 crirrio oosi- tioned inside the center of the ratchet wheel. LINK DETECTOR BRACKET TERMINAL LINK S-HCCK - Figure 4-6.

GAS SHUT-OFF VALVE INSTALLATION 1. Mechanical Gas Shut -Off Valve Installation. 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" diameter stainless steel cable that is connected to the control head. After the valve is installed in the gas line, 1/2" 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 CSP -1, SBP -1, and WBP-1 Pulley Elbows Maximum length of cable: 100 feet Maximum r of oullevs: 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 con- necting the cable to mechanical components. The crimp must never be used on a single cable. At the gas valve, loop the cable through the valve stem and secure it with the crimp provided (see Figure 4-18).

The cable proceeding, from the control,head must always enter the branch of the tee pulley. See Figure 4-20. r'• A tee pulley 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" up to 1 1/2" can be used on the same tee pulley. A 2" gas valve can be used only with another 2" gas valve. Gas valves from 2 1/2" up to 3" can be used on the same tee pulley. As an example, using a 3/4" gas valve with a 3" gas valve will not allow the 3" valve to fully open. CAUTION The tee pulley must never be used to connect multiple fusible link lines to a single control head. Figure 4-20.

PIPE AND NOZZLE INSTALLATION Allpipeends shall"'1 e61horoughly reamed after cutting and all oil and foreign matter removed from the pipe. It is recom- mended that the following procedures be followed: 1. 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. 2. 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. 3. The distribution piping and fitting connections, located in ther 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. 4. Do not over -tighten, but be sure the pine 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. All piping shall be securely fastened by means of pipe hand- ers and/or pipe straps. A union should be installed in the dis- charge piping, as close to the cylinder valve as possible, to permit disconnection and removal for inspection and service. Dry air or nitrogen should be blown through the discharge piping to remove chips and other debris prior to installation of nozzles. Nozzles shall be installed in accordance with the limitations described in Chapter Ill of this manual. Blow -off caps are provided for each nozzle. These will prevent dirt and grease from clogging the nozzle. 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. ULEX 3470 October 1, 2001 PN551274 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 op&ate the control head. The slide°plate will have moved fully to the right. The gas valve cable will have been released, causing the gas valve to close. Any auxiliary equipment connected to the dry contacts of the solenoid monitor and/or the Miniaiure Switch in the control head will have operated. If any of these events fail to occur, the problem must be investigated 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" 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 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 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. Once the control head is set, pull the pull handle on the remote pull station to assure that the control head ooerates. 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 eas valve ratchet wheel. CAUTION Before screwing the carbon dioxide pilot cartridge into the actuator, ensure that the actuator has a Teflon 0 -ring installed. Using a felt -tipped marker, write the date of installation in the gray area of 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.

AND MODEL EN -S (P/N 550966) MOUNTING The Model EN-MCU3 and/or EN -S Enclosure must be securely anchored to the wall using bolts or lac 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 4-24. FUSIBLE LINK DETECTOR INSTALLATION The Model EN-MCU3 Enclosure can support a fusible link detection system. The Model EN -S EIclosure cannot support a fusible link detection system and must be used in conjunction with the Model EN-MCU3 Enclosure or a Model MC-13/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 appii- ances and in each duct. See Chapter III for detector placement guidelines. Connect the fusible link brackets together using 1/2" 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 enc!csure through a top knockout. See Fusible Link Detector Installation Section of this chapter (pages 4-4 - 4-6) for fusible link installation guidelines. Before attaching the stainless steel cable to the fusible iink line ratchet wheel, it must be run below the fusible link line pulley in the enclosure. See Figure 4-25.

Check that the system has not!been tampered with. ie.. nozzles removed, nozzles not i aimed properly. piPino not suPported properly, blow off caps in place. 3. Check the entire system for mechanical damace. 4. Check all nozzle orifices to make certain thev are not piva-g-ed. Replace blow off caps or O-ring if necessary, CAUTION Before continuing, remove the cover from the con- trol head and insert the safety pin in the hole in the slide plate above the latching arm. This will secure the system. preventing accidental dis- charae. S. Disconnect the control head or1pneumatic 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 sh6t-off valve a ':nd remote pull station are functioning properly. 6. Inspect the fusible link detectors and pulley elbows for excessive grease -buildup. Clean or replace links or elbows if necessary. 7. Reinstall the carbon dioxide pi.Ict cartridge, reconnect the control head, and replace the control head cover and nylon tie. 8. Inspect the cylinder pressure. Tap the gauge lightly to ensure the needle is moving freely. 2. Disconnect the discharge pi ' oing from the valve outlet. Using air or nitrogen, blow out the piping. Replace all nozzle caps. 3. Remove the cylinder to verify the fill weight as shown on the nameplate. 4. Replace the carbon dioxide Pilot cartrido.e. 5. Replace all fusible link detectors. 6. Reconnect the control head. Replace the control head cover and nvIon tie. 12 -YEAR MAINTENANCE Along with the reo ' uired annual maintenance requirements, the fanks must be removed from the system. pro ' pedy dis- cnaroed. and hvdrostatically tested per the requirements of NFPA-17A. The tank should be refilled with fresh agent. ULEX 3470 PN551274 October 1, 2001 CHAPTER VI SYSTEM RECHARGE GENERAL v, This chapter will detail'-fhe basic information necessary for proper recharge of the Pyro-ChemiKitchen Knight II Restaurant Fire. Suppression System. However, before, attempting any system recharge, it is necessary to attend a Factory Certification Training Class and become certified to install, maintain, and recharge the Pyro-Chem Kitchen Knight 11 Restaurant Fire Suppression System. Because it is difficult to completely understand every aspect of an intricate pre-engineered system simply by reading the Technical Manual, Pyro-Chem Kitchen Knight II will not be responsible for system recharge performed by any non -certified person(s). 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 -energized to avoid any chance of electrical shock resulting from the cleaning process of electrically conductive alkaline liq- uid 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 vio- lent steaming and/or scattering. SYSTEM RECHARGE NOTE Determine the cause of system discharge and correct II immediately before performing system recharge. After discharge, inspect the entire system for mechanical damage. If the tank has sustained any mechanical dam- age, it must be hydrostatically tested before refilling. 2. Disconnect the 1/4 in. actuation tubing or the control head from the top of the tank valve. 3. 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. t,.Chapter 6 -System Recha F 4 - rg6VZ 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: The complete piping system must be flushed after a discharge. Flushing solution, Part No. 79656, must be used when flushing the system. The solution is shipped in a 32 oz. container. A PCL -300 tank requires 1 contain- er of solution. A PCL -460 requires 1 1/2 containers, and a PCL -600 requires 2 containers. To prepare the system for flushing: a. Pour the required amount of flushing solution into the tank. b. 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. c. Reinstall valve and pickup tube and pressurize tank to 225 psi 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 pipina net- work must be blown out with air or nitroaen 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, using measuring stick, Part No. 551039. Tank should be filled to a tolerance of—0/=1/8 in. from the mark level on the measuring stick. NOTE During filling, the agent temperature should be 60 °F to 80 °F (16 °C to 27 °C). ULEX 3470 PN551274 October 1, 2001 Chapter 6 = Systern Recharge Page 6=2 11. Reinstall valve and pickup tube and pressurize tank to 225 psi (using ?echarge adaptor, Part No. 551240). Invert the tank after'pre ' ssurizing to clear any air trapped in the pickup tube. Using a soap solution, check for leaks. Reinstall to piping ,network. NOTE The._pressure gauge attached to the tank valve should not be used to determine when the charging pressure has been reached. A pressure regulator must be used. 12. Replace all fusible links by following the instructions list- ed in the Installation Section. 13. Reset control head(s). accessories. pull stations and cas valves by following the instructions listed in the Installation Section. ULEX 3470 October 1, 2001 PN551274ii t
