Those who install, operate, recharge, or maintain ihese fire sup- pression systems should read this entire manual. Specific sec- tions 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 per- formed by an individual who attended an ANSUL training pro- gram and became trained to install, recharge, design, and main- tain the ANSUL system. Fire suppression systems are mechanical devices. They need periodic care. Maintenance is a viial 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 of Smoke and Grease-Laden Vapors from Commercial Cooking Equipment) and NFPA 17A (Standard on Wet Chemical Extinguishing Systems) by an authorized ANSUL disiributor. To provide ma�cimum assurance that the fire suppression system will operaie effectively and safely, mainte- nance must be conducted at six-month intervals, or earlier if the situation dictates. Twelve-year maintenance must include agent tank hydrostatic testing. ANSUL PART NO. 418087-11 ANSUL, FNSUL AUTOMHN antl ANSULEX are Vatlemerks ot Tyco Inlerna�ional Litl. or ils alfiliates.

It is a pre-engineered group of inechan- ical and electrical components for installation by an authorized ANSUL distributor. The basic system consists of an ANSUL AUTOMAN regulated release assembly which includes a regulat- ed release mechanism and a liquid agent storage tank housed within a single endosure. Nozzles, detectors, cartridges, liquid agent, fusible links, pulley tees, and pulley elbows are supplied in separate packages in the quantities needed for each fire suppres- sion system arrangement. The system provides automatic actuation; or it can be actuated manually through a remote manual pull station. The system is also capable of shutting down appliances at system actuation. For appliance shutdown requirements, refer to the current version of NFPA 17A, "Standard For Wet Chemical Extinguishing Systems;' and NFPA 96, "Standard For Ventilation Control and Fire Protection of Commercial Cooking Operations." Additional equipment includes: remote manual pull siation, � mechanical and electrical gas valves, and electrical switches for automatic equipment and gas line shut-off. Accessories can be added, such as alarms, warning lights, etc., to insiallations where required. The R-102 system suppresses fire by spraying the plenum area, the filters, cooking surfaces, and the exhaust duct system with a predetermined flow rate of ANSULEX Low pH Liquid Fire Suppressant. When the liquid agent is discharged onto a cooking appliance fire, it cools the grease surface, and reacts with the hot grease (saponification) forming a layer of soap-like foam on the surface of the fat. This layer acts as insulation between the hot grease and the atmosphere, thus helping to prevent the escape of combustible vapors. Exhaust fans in the ventilating system shouid be left on. The forced draft of these fans assists the movement of the liquid agent through ihe ventilating system, thus aiding in the fire suppression process. These fans also provide a cooling effect in the pienum and duct after the fire suppression system has been discharged. The system is UL listed with or without fan operation. Make up or supply air fans, integral to the exhaust hood(s) being protected, shall be shut down upon system actuation. Along with the fire suppression system, the total system design must include hand portable fire extinguisher(s) located within the cooking/restaurant area that can be used to manually suppress a fire that may be burning in an unprotected area. Class K e�ctin- guisher(s) must be provided for hazards where there is a potential for fires involving combustible cooking media (vegetable or animai oils and fats). Refer to NFPA 10, "Standard For Portable Fire Extinguisher;' for additional information. UL LISTING The R-102 Restaurant Fire Suppression System has been tested and is listed by Underwriters Laboratories, Inc. as a pre-engi- neered system. The system is in compliance with ULTest Standard 300. These tests require extinguishment of fires which are initiated in deep fat fryers, ranges, griddles, char-broilers, woks, upright broilers, chain-broilers, filters, plenum chambers, hoods, and ducts after pre-loading each appliance with a pre- scri6ed amount of cooking grease. Each fire is allowed to progress to maximum intensity before the fire suppression system is actuated.

This regulated release assembly is used in single, double, and multiple-tank systems and must be mounted to a rigid surface. The release mechanism can be used to interconnect both the actuation and expellant gas lines as required per system design. The regulator is designed to allow � a constant flow of gas into the tank at 110 psi (7.6 bar) when the system is actuated. The agent tank must be ordered separately. In single, double, and multiple-tank systems, the provided expel- lant gas hose connects the agent tank to the bottom outlet of the regulator. In double and multiple-tank system configurations, the back outlet of the regulator is used as an expellant gas feed for one additional tank-enclosure or tank-bracket hookup. The enclo- sure contains the required knockouts to facilitate this connection. If a pressure switch is to be attached to the regulator, addiiional fit- tings are required. The tank is mounted within the enclosure. The tank contains an adaptorRube assembly with a burst disc union. The burst disc helps prevent siphoning of the agent up the pipe due to significant temperature fiuctuations in the area where the tank is located. The � tank is stainless steel and, under normal conditions, requires hydrostatic testing every twelve years. The detection and additional equipment required per system design are connected to the release mechanism. The enclosure contains knockouts to facilitate detection and additional hookups. The system can be actuated automatically or manually. Automatic actuation occurs when a fusible link within the detection system separates in a fire condition. Manual actuation of the system occurs when personnel pull on the remote manual pull station pull ring.

The Agent Distribution Hose can be utilized with castered cooking appliances with castered supports found in commercial kitchens. The hose allows for movement of the appli- ance for cleaning without having to disconnect any fire suppres- sion system discharge piping. Note: The Agent Distribution Hose is authorized for use with only UL Listed ANSUL Wet Chemical Restaurant Fire Suppression Systems. SYSTEM DESIGN The ANSUL R-102 Restaurant Fire Suppression System may be used on a number of different types of restaurant cooking appli- ances and hood and duct configurations. The design information listed in this section deals with the limitations and parameters of this pre-engineered system. Those individuals responsible for the design of the R-102 system must be trained and hold a current ANSUL certificate in an R-102 training program. The R-102 and the PIRANHA systems use compatible agenis and components, therefore, they may be used together for cooking appliance, hood, and duct protection. The primary ANSUL AUTOMAN Release can be either an R-102 or a PIRANHA ANSUL AUTOMAN Release and can actuate up to two additional R-102 or PIRANHA Regulated Actuators. In systems utilizing a 701 remote release, any combination of the maximum number of regulated actuators can be used. • Both systems must actuate simultaneously. • Each system must be designed and installed per its appropri- ate manual. • Adjacent appliances requiring protection must be protected with the same type of system, eiiher R-102 or PIRANHA, unless the center-to-center spacing between the adjacent ' R-102 and PIRANHA nozzles is no less than 36 in. (91.4 cm). When appliances are protected with R-102 nozzles, the hood and connecting duct above those appliances cannot be pro- tected with PIRANHA nozzles. Mixing systems in a common plenum is not allowed. One of the key elements for restaurant fire protection is a correct system design. This section is divided into ten sub-sections: Noz- zle Placement Requirements, Tank Quantity Requirements, Actu- ation and Expellant Gas Line Requirements, Distribution Piping Requiremenis, Detection System Requirements, Manual Pull Sta- tion Requirements, Mechanical Gas Valve Requirements, Electri- cal Gas Valve Requiremeots, Electrical Switch Requirements, and Pressure Switch Requirements. Each of these sections must be completed before attempting any installation. System design sketches should be made of ali aspects of design for reference during installation. NOZZLE PLACEMENT REQUIREMENTS This section gives guidelines for nozzle type, positioning, and quantity for duct, plenum, and individual appliance protection. This section must be completed before determining tank quantiry and piping requirements. Duct Protection — Single Noule All duct protection is UL listed without limitation of maximum duct length (unlimited length). This includes ail varieties of ductworks both horizontal and vertical including ducts that run at angles to the horizontal and ducts with directional bends. The R-102 system uses different duct nozzles depending on the size of duct being protected. SECTION IV — SYSTEM DESIGN UL EX3470 ULC EX3470 Page 4-1 7-1-09 REV.B GENERAL INFORMATION 1.

Note: Noules to protect ducts with a transition that is more than 4 ft(72 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. See Figure 4. FIGURE 4 000„< Electrostatic Precipitator P�otection Some restaurant ventilating ducts have an electrostatic precipita- � tor installed at or near the base. These precipitators are generally � small and are used to aid in the cleaning of ezhaust air. . Ducts with precipitators located at or near the base can be pro- tected using duct nozzle(s) above the precipitator and 1/2N noz- zle(s) (Part No.479334) for the precipitator.One 1/2N nozzle must be used for each cell being protected. This nozzle tip is stamped with 1/2N, indicating that it is a 1/2-flow nozzle and must be count- ed as 1/2 flow number. When protecting ducts equipped with precipitators, the duct noz- zle(s) must be installed above the precipitator and aimed to dis- charge downstream. If the area above the precipitator is a duct, the nozzle(s) must be positioned according to duct protection guide- lines. If the area above the precipitator is a transition, the transition guidelines must be followed. The i/2N nozzle (Part No. 419334) must be centered 10 to 26 in. (25 to 66 cm) below the precipitator and aimed to discharge at the center of each precipitator cell. However, if it is physically impossi- ble to mount the nozzle at 10 to 26 in. (25 to 66 cm) due to pre- cipitator placement, the nozzle may be mounted closer than 10 in. (25 cm). See Figure 5.

Plenum Protection The R-102 system uses the 1 W Nozzle (Part No. 419336) or the 1 N Nozzle (Part No. 419335) for plenum protection. The 7 W noz- zle tip is stamped with 1 W and the 1N nozzle tip is stamped with 1 N, indicating they are one-flow nozzles and must be counted as one flow number each. When protecting a plenum chamber, the entire chamber must be protected regardless of filter length. VERTICAL PROTECTION — GENERAL ' 1 W NOZZLE — PART NO. 419336 — SINGLE AND "V" BANK ' PROTECTION One 1 W nozzle will protect 4 linear feet (1.2 m) of plenum. The maximum distance from the end of the hood to the first and last nozzle must be no more than 2 ft(0.6 m). After the first nozzle, any additional nozzles must be positioned at a maximum of 4 ft(1.2 m) apart down the entire length of the plenum.The plenum width must not exceed 4 ft(12 m). (The 1 W nozzle can be used on single or V-bank filter arrangements.) See Figure 6. FIGURE 6 OW19] When protecting plenums with the 1 W nozzle, two options of cov- erage are available: Option 1: The 1 W nozzle must be on the center line of the single or "V" bank filter and positioned within 1-20 in.

(5 - 10 cm) � rwun� � i For a plenum, either single or "V" bank, with a linear extension longer than 10 ft(3.1 m), each bank may be protected using one 1N nozzle every 10 ft(3.1 m) or less depending on the overall length of the plenum. See Figure 12. The nozzles may point in the opposite directions as long as the entire plenum area is protected, and the 10 k(3.1 m) limitation is not exceeded. See Figure 13. The nozzle positioning shown in Figure 14 is not an acceptable method of protection because the plenum area directly under the tee is not within the discharge pattern of either nozzle. FIGURE 12 orozos FIGURE 13 ��o> FIGURE 14 orozae SECTION IV — SYSTEM DESIGN UL EX3470 ULC EX3470 Page 4-7 10-1-02 REV.3 Appliance Protection The following pages detail types of appliance protection. Each design requires several factors: correct nozzle choice, correct noz- zle height above hazard, correct nozzle location and correct aim- ing point. Fryer — Single Noale Protection 1. Design requirements for fryers are broken down into rivo types. A. FRYERS WITHOUT DRIPBOARDS If the fryer does not include a dripboard, measure the internal depth (horizontal dimension from front to back) and length of the frypot. B. FRYERS WITH DRIPBOARDS If the fryer includes any dripboard areas, measure both the internal depth (horizontal dimension from front to back) and length of the frypot portion, and then measure the internal depth and length of the overall hazard area including any dripboard areas. 2. Using Table, "Maximum Cooking Area Dimension — Single Nozzle Fryer Protection;' determine which nozzle is needed to proiect the fryer based on the maximum dimensions listed. A. If the Fryer does not include a dripboard, use the maxi- mum dimensions listed in the first column of the table to select the correct nozzle. B. If the fryer includes any dripboard areas, use both the maximum frypot dimensions in the first column of the table, and the maximum overall dimensions in the second column of the table to select the correct nozzle. None of the maximum dimensions in either column may be exceeded. 3. If either the mauimum frypot or the overall sizes are exceed- ed, an additionai nozzle(s) will be required. Refer to the mul- tiple nozzle requirements. Example: A fryer with a dripboard. The inside of the frypot without the dripboard measures 18 in. in depth x 18 in. in length (46 cm x 46 cm) and the inside of the overall area including the dripboard measures 18 in. in depth x 24 in. in length (46 cm x 61 cm). From the Table "Maximum Cooking Area Dimension — Single Nozzle FryerProtectian," either the 3N or the 290 nozzle should be select- ed to protect the fryer, depending on the maximum nozzle height above the fryer and the positioning requirements allowed. Refer to app�opriate Figures.

FIGURE 19 SECTION IV — SYSTEM DESIGN UL EX3470 ULC EX3470 Page 4-10 REV.7 7-i-09 Fryer — Multiple Noule Protection Design Requirements: 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 dripboard can be used, regardless of whether the fryer has a dripboard or not. � The mauimum size fryer that can be modularized is 864 in.z .(5574 cm2) or in terms of R, s ft2 (o.s m2). 1. Design requirements for multiple nozzle fryers are broken down into lwo types: 2. � A. FRYERS WITHOUT DRIPBOARD(S) If the fryer does not include a dripboard, measure the inter- nal depth (horizontal dimension from front to back) and length of the frypot. Then, multiply the depth and length to obtain the area of the frypot in square inches. B. FRYERS WITH DRIPBOARD(S) If the fryer includes any dripboard areas, measure both the internal depth and length of the frypot portion, and then measure the internal depth and length 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 depih and length dimensions. Divide the frypot or overall vat into modules, each of which can be protected by a single nozzle, based on the ma�cimum dimension and area coverage of the noule as specified in Table, "Maximum Cooking Area Dimension — Multiple Nozzle Protection" A. If the module considered does not include any portion of the dripboard, use only the maximum irypot area and max- imum dimension listed in ihe first column of the table io select the correct nozzle. B. If the module considered includes any dripboard areas, use both the maximum frypot area and dimension listed in the first column of the table, and the maximum overall area and dimensions listed in the second column of the table to select the correct noule. None of the maximum dimensions in either column may be exceeded. If either the maximum frypot or the overall sizes are exceeded, the area divided into modules will need to be rede- fined with the possibility of an additional nozzle. Options For Modularizing Fryers The following Figure 20 shows approved methods of dividing (mod- ularizing) fryers so that each section can be properly protected.

Because the fryer is 30 in. (76 cm) in length, it exceeds the coverage of a single nozzle. Dividing the length in half, each module now has an overall vat dimension of 24 in. in depth x 15 in. in length (61 x 38 cm). From the Table, "Maximum Cooking Area Dimension — Multiple Nozzle Fryer Protection,"either the 3N or the 290 nozzle should be select- ed to protect each fryermodule, depending on the maximum noz- zle height a6ove the fryer and the positioning requirements allowed.

Chain broilers utilizing catalytic converters can be protected from overhead using model specific protection iden- tified in the "Specific Application by Model" section in System Design. Or, they can be protected with standard 1 N nozzle hori- zontal chain broiler protection with the nozzles positioned at either end of the chain broiler openings. Refer to the Horizontal Chain Broiler Protection section for specific design information. Horizontal Chain Broiler Protection The R-102 system can use hvo 1 N Nozzles (Part No. 419335) for . horizontal chain broiler protection. The nozzle tip is stamped 1 N, indicating that this is a one-flow nozzle and must be counted as one flow number (total of two flow numbers for each chain broiler being protected). Two 1N nozzles are always needed for chain broiler protection when the hazard area to be protected does not meet the "Overhead Broiler Protection" requirements. The maximum inter- nal size of the broiler is 43 x 31 in. (109 cm x 79 cm). The nozzles must be positioned at each end of the enclosed cooking chamber 1 to 3 in. (2.5 to 7.5 cm) above the surface of the chain and a max- imum distance of 4 in. (10 cm) away from the broiler opening. The nozzles may be mounted at either corner as long as they are at opposite ends of the chain broiler and positioned to discharge . diagonally across the top of the chain. See Figures 53 and 54. MAXIMUM INTER BROILER SRE 4F (109 X ]9 cm) N. LS cm) � FIGURE 53 FIGURE 54 o�o�, Overhead Chain Broiler Protection . The R-102 system can use two 1 W Nozzles (Part No. 419336) for overhead chain broiler protection. The nozzle tip is stamped with 1 W, indicating that this is a one-flow nozzle and must be counied as one flow number. Overhead protection is only available For chain broilers with exhaust opening dimensions that are not less than 60% of the internal broiler length and not less than 60 % of the internal broiler width, to a minimum size of 12 in. x 12 in. (30.5 x 30.5 cm). Internal broiler size can not be larger than 32 in. x 34 in. (81 x 86 cm). When overhead protection is used, the nozzles must be centered above ihe exhaust opening within 4 to 8 in. (10 to 20 cm) of each other and they must be located 10 to 26 in. (25 to 66 cm) above � the top of the broiler surface. See Figure 55. a-a iN. �io-zo cm� � r�61N. / `�v/���'%o�%���� 121N.

If the opening is not square, the nozzles must be posi- tioned along the centerline, parallel to the longest side of the open- . ing. See Figure 56. TOP VIEW TOP VIEW FIGURE 56 �:,s Note: The CB Metal Blow-off Cap must be used when using chain broiler protection. Overhead Chain Broiler Protection (Continued) Example No. 1- Internal broiler size is 24 in. long x 20 in. wide (67 x 57 cm), with an opening of 16 in. x 16 in. (40.6 x 40.6 cm). To determine minimum opening size, multiply the internal length and the internal width by 0.6: Length of opening - 24 in. x 0.6 = 14.4 in. (61 cm x 0.6 = 36.6 cm) Width of opening - 20 in. x 0.6 = 12.0 in. (51 cm x 0.6 = 30.5 cm) The minimum allowable opening for overhead protec- tion would be 14.4 in. x 12.0 in. (36.6 x 30.5 cm). This example would be acceptable for overhead pro- tection. Example No. 2- Internal broiler size is 30 in. long x 24 in. wide (76 x 61 cm) with an opening of 22 in. x 12 in. (56 x 30 cm). To determine minimum opening size, multiply internal length and internal width by 0.6: Length of opening - 30 in. x 0.6 = 18.0 in. (76cmx0.6=45.7cm) Width of opening - 24 in. x 0.6 = 14.4 in. (61 cm x 0.6 = 36.6 cm) Minimum allowable opening for overhead protection would be 18 in. x 14.4 in. (45.7 x 36.6 cm). Because this broiler has an opening of 22 in. x 12 in., the 12 in. width is below the minimum allowable cai- culated dimension of 14.4 in. (36.6 cm) and therefore would not be acceptable for overhead protection. � Salamander Broiler Protection The R-102 system uses three different nozzle locations for sala- mander broiler protection. All of the design options require a one- flow nozzle. Salamander Broiler Protection - 1 N(1-Flow) Noule Overhead A salamander broiler with a maximum hazard area (internal broil- er chamber) of 16 in. (41 cm) deep x 29 in. (74 cm) wide can be protected using a 1 N nozzle, Part No. 419335. The nozzle tip is .stamped with 1 N, indicating thai this is a one-flow nozzle. The single 1 N nozzle must be located directly in line with either vertical edge of the broiler opening, 6 in. (15 cm) to 12 in. (30 cm) in front of the broiler, and 0 in. to 12 in. (30 cm) above the top of the broiler. The nozzle must be aimed at the center of the broiler . opening. See Figure 57a.

(61 cm) and a total cooking area which does not � exceed 288 in.z (7858 cm2). The nozzle tip must be located 78 to 40 in. (46 to 102 cm) above the hazard surface. When using this nozzle for natural charcoal broiler protection, the nozzle must be positioned anywhere along or within the perimeter of the maximum cooking area and aimed at the center of the cooking surtace. See � Figure 61. The coverage of such appliances only applies when the depth of the charcoal does not exceed 4 in. (10 cm).
