Design, installation, recharge. and maintenance of the system must contorm to the limitations detailed in this manual and performed by an individual who attended a PYRO-CHEM train' ing program and became trained to install, recharge, design, aod maintain the PYRO-CHEM system. Fire suppression systems are mechanical devices. They need periodic care. Maintenance is a vital step in the performance 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 ot Smoke and Grease-Laden Vapors from Commercial Cooking EquiPment) aod NFPA 17A (Srandard on Wet Chemical Extinguishing Systems) by an authorized PYRO-CHEM distributor. To provide maximum assurance that tlre lire suPpression system will operate effec- Ively and safely, maintenance must be conducted at six-month intervals. or earlier if the situation dictales. Twelve-year mainte- nance must include agent tank hydrosbtic testing The PYRO-CHEM KITCHEN KNIGHT ll Pte-Engineered Sysiem utilizes a wet chemical agent specifically designed to suppress reslaurant cooking area fires. The system provides automatic actuation and can te manually actuated through a remote mechanical pull station. Upon actuation, the system discharges a pre-determined amount of 39enl. to the duct, plenum, and cooking appliances. The agent acts to suppress fires in three waysr 1. The chemical chain reaction causing combustion is inter' rupted by both the agent itsolf and the resulling steam formation. 2. The agent cools the fire bringing it below aulo-ignition tempeftrture. 3. The agent reacts with hot grease lorming a soap'like layer (saponification) thal helps prevent the escape ot combusti- bte vapors, thus pleventing te-ignilion. SECTION 1 .

KITCHEN KNIGHT ll Reslaurant Fte Supp(ession Manual GENERAL The KITCHEN KNIGHT Il Restaurant fire Suppression System may be used on a number ot different types of restaurant cooking appliances and hood and duct conligurations. The design information Iisted in this section deals with the limitations and parameters of this pre-engineered sysEm. Tllose individ- uals responsible for the design or the KITCHEN KNIGHT ll system must be trained and hold a current PYRO-CHEi\,1 certifi- cate in a KITCHEN KNIGHT ll lraining program. NOZZLE COVERAGE AND PLACEMENT This section will provide guidelines tor determining nozzle type, positioning, and quantity for duct, plenum. and apPliance protection. Duct Protection It is not required that the fan be shut down ot 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 aod vertical including ducts that run at angles to the horizontal and ducts with directionat bends. Duct proteclion requires that a nozzle be positioned to discharge into the duct. Two nozzles are available for duct proteclon. The Model lL Duct Nozzle (Part No. 551026) is a one flow nozzle A single lL nozzle is caPable of Protecting square or rectangular ducts with a maximum perimeter ol50 in- (1270 mm) (maximum side of '16 3/4 in. (425 mm)), with the diagonal being a maximum oF 18 3/4 in. (476 mm). h can also protect a round ducl with a maximum diameter ot 16 in. (406 mm). The Model 2D Duct Nozzle (Part No. 551038) is a two flow nozzle, A single 20 nozzle is capable of proteclng square or rectangular ducls wilh a n'laximum Perimetel of 100 in. (2540 mm), with the diagonal being a maximum of 37 3/8 in (949 mm). lt can also protect a round duct with a maximum diameter of 3'l 7/8 in. (809 mm). When lwo 2D duct oozzles are used to protect a single duct, the cross sectional alea of the duct must be divided into two equal symmetical areas. The nozzle mu$ then be installed on the centerline of the area it protects and aimed direcuy into lhe duct opening. SECTION 3 - SYSTEM DESIGN uL EX3830 ULC EX3830 2014-NOV-10 REV.06 PAGE 3-1 The nozzle(s) must be installed on the centerline of the duct, with the tip located 0 to 6 in. (0 to 152 mm) into he opening, and aimed directly into the duct oPening. See Figure 3-1. ln installations where a UL listed damper assembly is employed, the duct nozzle can be installed beyond the 6 in. (152 mm) maximum, to a pointjust beyond the damper assembly that will not interfere with the damper, Exceeding lhe maximum ot 6 in. (152 mm) in thls way will not void the UL listing of the system. 0.6 rN (0.15? mnl INTO OUCT rL oR 20 NOZ2LE t t-I I FIGURE 3-1 - -t KITCHEN KNIGHT ll Restautant Fte Suppession Manual NOZZLE covERAGE AND PLACEMENT (Continued) Duct Protection (Continued) Transition Ducts -The protection ofnon-standard ducts should be reviewed by the authority having jurisdiction. PYRO-CHEIVI KITCHEN KNIGHT ll recommends that transition ducts be protected as follows: a.

Two nozzles are available for fryer protection: High proxim" ity and low proximity. The Model 2H Nozzle (Part No. 551028) is used for high proximity fryer protection. This nozzle is a two tlow nozzle. The nozzle must be located anywhere within the perime- ter ot the hazard area, 24 in. to 48 in.

FIGURE 3.S 1.b Fryers - Multiple Nozzle Protection Fryers exceediflg the coverage ol 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 proteclion, lhe longest side allowed for a fryer wilh drip board can be used, regardless of whether the tryer has a drip board or nol. The maximum size tryer lhat can be modularized is 854 in.2 (55741 mm2), Design requirements for multiple nozzle fryers are broken down as follows: '1. lF lhe lryer includes any dripboard areas, measure both the internal lenglh (kont to back) and widlh of the frypot portion. Then measure the internal length and width ol the overall hazard area including aoy driPboard areas. Determine tlre area of both the frypot and the area ot the overall vat by multiplying corresponding length and width dimensions. 2. Divide the lrypot or overall va( into modules, each of which can be protected by a single nozzle, based on the maximum dimension and 3rea coverage of the nozzle as specified in Table 3-2i Design. . l, the module considered do€s not include any ponion ol the dripboard. use only the maximum Frypot area and maximum dimension listed in Table 3-2: Design. ' ll the module considered includes any dripboard areas, use botlr the maximum lrypot area and dimension listed in Table 3.2: Design. and lhe maximum overall area and dimeosion listed in Table 3-2: Design. 3. None ol tlre maximum dimensions may be exceeded. lf 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. 2lr ' i PRoxrMriYI NOZ2|-EI tocar€o oN-t8E IN, tN. e EOGEOF 211.2L -Q._o-r- _ SECTION 3 - SYSTEM DESIGN UL EX383O ULC EX383O PAGE 3-6 REV.06 2014-NOV-10 NOZZLE COVERAGE AND PLACEMENT (continued) Appliance Proteclion (continued) TABLE 3-2: DESIGN Longest Side Vat Coverage Coverage with Drip Oplion 1 21 314 in.
