It is designed to protect commercial restaurant cooking appliances, hoods, and ducts as described in this manual. Installation and maintenance of the Kitchen Mister System must be in compliance with the parameters set forth in this manual and be performed by a factory trained, Authorized Buckeye Fire Equipment Distributor. CAUTION This technical manual can in no way be considered sufficient to completely understand the proper design, installation, and/or maintenance of the Kitchen Mister System. Buckeye Certified Training is required to become Authorized to perform these procedures. Buckeye Fire Equipment will not be responsible for system(s) designed, installed, or maintained by individuals or companies not trained and Authorized by Buckeye Fire Equipment. How the Kitchen Mister Works The Kitchen Mister System utilizes a potassium based liquid fire extinguishing agent specifically designed for grease laden fires such as those associated with restaurant cooking areas. The Kitchen Mister agent works to suppress commercial kitchen fires in three ways: The agent interrupts the chemical chain reaction causing combustion, thus extinguishing the fire. The agent is discharged in a very fine mist, cooling the fire to below its auto-ignition temperature. The agent reacts with grease to form a foam-like layer commonly called saponification that starves the fire of oxygen, stopping combustion and preventing re-ignition. The system will automatically actuate upon detection of a fire or can be manually actuated by using a remote manual pull station positioned at the point(s) of egress from the hazard area. When the system is actuated, a pre-determined amount of fire extinguishing agent is discharged through the piping network and fixed nozzles to the duct, plenum, and cooking appliances. The agent is discharged as a very fine mist that quickly acts to suppress grease laden fires. System Temperature Limitations The operating temperature range of the Kitchen Mister System is 32°F (0°C.) minimum to 120°F (490C.) maximum.

Placement: See Figure 3.7. Aim point: See Figure 3.7. The Model N-IHP nozzle is a one (1) flow point nozzle that can protect a plenum (either single bank or V-bank) of 12 feet (3.7 m) in length and 4 feet (12 m) in width per nozzle. Larger plenums must be divided into 12 foot (3.7 m) sections, with each section protected with a separate nozzle. See Figure 3-7. Plenum: V-bank Nozzle Placement The nozzle must be located at the center of the V-bank width and down 1/3 of the vertical height, within 6 inches (15 cm) of the end of the plenum or plenum module and aimed down the length of the plenum. See Figure 3-7. Plenum: Single Filter Bank Nozzle Placement The nozzle must be located at a point that is 2" (5.1 cm) from the back edge of the filter and 1/3 of the vertical height of the filter, within 6 inches (15 cm) off the end of the plenum or plenum module and aimed down the length of the plenum.

Model N-IHP Plenum Nozzle Placement and Aiming Note: These examples are typical and do not represent every acceptable nozzle configuration, only a representative sample of them. Designer Note For plenums that exceed 12 feet (3.7 m) in length and therefore require multiple nozzles, it is recommended that the total length be divided into equally sized protection zones and protected accordingly. So a 16 foot (4.9 m) long plenum should be divided into two 8 foot (2.4 m) zones, with a nozzle protecting each, as opposed to a 12 foot (3.7 m) zone and a 4 foot (1.2 m) zone. BPN: BFR-TM Chapter 3 - System Design Page 3 - 3 Revision 5 APPLIANCE PROTECTION Each different appliance must be protected in a specific manner with regard to nozzle selection, placement, and aiming. No deviations from these parameters are allowed and failure to comply completely with these requirements will void the UL Listing of the system and may render the system ineffective. In order to properly understand this section, several key terms need to be defined in advance. DESIGN TERMINOLOGY Nozzle Height: The distance from the tip of the discharge nozzle to the top surface of the appliance (except for woks, in which case the bottom of the wok is used). Hazard Area: All nozzle coverages include the maximum size of the hazard area they can protect. Hazard area is NOT the overall size of the appliance being protected, but rather the actual size of the portion of the appliance used for cooking. Appliances Requiring Multiple Nozzles Some appliances may need to be protected by multiple nozzles because of their size. If the size of an appliance is larger than the approved coverage for that appliance, multiple nozzles must be used. This is accomplished by dividing the hazard area into individual zones that comply with the parameters of the listing for that appliance. In this case, each zone will be protected as an individual appliance with respect to nozzle placement and aiming.

The maximum and minimum pipe length for each size agent cylinder is based on total internal pipe volume, regardless of the diameter of the pipe used. All piping parameters are based on total system piping and do not make a distinction between branches and supply line piping. Note: Pipe and fittings must be furnished by the installer. Pipe shall be Schedule 40 black, chrome plated, or stainless steel pipe. Fittings shall be rated 150 lb (68 kg). PIPING VOLUME CHART Allowable Pipe Sizes Volume Per foot 3/8 in. (17.1 mm OD) pipe 37.5 mL./ft. (123mL/m) 1/2 in. (21.3 MM 00) pipe 59.8 mL./ft. (196mLJm) Example: 20 feet (6.1 m) of 3/8" (17.1 mm 00) pipe is equal to 750 mL. of pipe volume [20 ft. (6.1 m) X 37.5 mL./ft. (123m1Jm) = 750 mL.). MAXIMUM PIPING PER CYLINDER SIZE Max. Max. Pipe Max. Pipe Cylinder Flow Volume Vol. Between Size Points (mL.) any two (2) Nozzles. (mL.)

Minimum Piping Requirements Note: Minimum piping requirements ONLY apply when protecting a wok, deep fat fryer, or range. Minimum number of elbows before the closest nozzle protecting a fryer, range, or wok shall be five (5). The minimum piping volume before the closest nozzle protecting a fryer, range, or wok shall not be less then 360 mL. The total system pipe volume shall not be less then 660 mL. for all cylinder sizes. A system shall have a minimum of three (3) flow points. General Pipinq Requirements All piping must be either 3/8 (17.1 mm OD) or 1/2" (21.3 mm 00). The maximum number of elbows allowed per system are: BFR-5: 20 elbows maximum BFR-10/15/20: 25 elbows maximum The maximum number of elbows between any two nozzles is five (5). The maximum vertical rise of the supply line is 10 feet (3 m), this is either the maximum elevation difference between tank outlet and the highest nozzle or tank outlet and the highest or lowest point in the piping system. The maximum vertical rise of any nozzle above the supply line is 2 feet (0.6 m). No traps are allowed in the piping system. Note: A 'trap" is defined as a section of pipe that would allow liquid to accumulate, such as, either a low point in the piping layout or piping that extends past the last discharge point. When different sized piping is used in the same system, the largest diameter pipe must be closest to the cylinder and sizes are to decrease as they reach the nozzle. So piping always runs from larger to smaller diameter. Elbow(s) or swivel adaptors used at the nozzle for aiming DO NOT count toward the total elbows allowed per system or the number of elbows between two (2) nozzles. BPN: BFR-TM ULEX 6885 ULC-EX 6885 January 1, 2013 Chapter 3 - System Design Page 3- 14 Revision 5 DETECTOR PLACEMENT Detectors (fusible links) are required to be placed in the air stream of each appliance (one detector per appliance) and in the opening of the exhaust duct(s) of protected ventilation hoods. Detectors shall be located in the plenum area of the ventilation hood behind the filters, which provide protection for the detection system. Exhaust Duct Detector Placement Each exhaust duct must have at least one (1) detector installed. The detector is to be centered in the duct entrance and no more than 12" (30.5 cm) into ductwork. Cooking Appliance Detector Placement Each cooking appliance with a continuous cooking surface area of less than 48" (122 cm) x 48" (122 cm) must be protected by one (1) detector. The detector is to be located over the surface of the appliance and in its air stream when the ventilation system is turned on. Cooking appliances with continuous cooking surfaces larger than 48" (122 cm) x 48" (122 cm) must be protected by multiple detectors, using one detector for every 48" (122 cm) x 48" (122 cm) of continuous cooking area. Exception: If a cooking appliance or appliances are located under a duct opening where a detector has been mounted, it is not necessary to utilize an additional detector as long the duct detector is not more than 12" (30.5 cm) into the duct opening.

(UL) does not currently have a testing procedure for gyro cookers; however, these appliances may require protection based on the judgment of the local authority having jurisdiction. When protection is required, gyro cookers are protected in the same manner as an upright broiler (see page 3-8 and 3-9 of the Buckeye Technical Manual, P/N BFR-TM). One model N-1LP nozzle is used to protect a gyro cooker with a maximum cooking area of 36' wide by 24" deep. For this application, the nozzle is to be located in the top corner of the appliance and aimed at the bottom center. If the appliance is equipped with doors, the nozzle must be positioned in such a manner that the doors do not interfere with the discharge of the nozzle, If you have any additional questions please do not hesitate to contact me. Sincerely, Bruce Euler Pre-engineered Systems Manager Buckeye Fire Equipment Company ISO 9001 Registered E-mail; bfec@buckeyef.com Website: www.buckeyefire.com June 29, 2017 Mr. James Wiseman San Diego Fire Protection Subject: Response to your inquiry regarding the applicable NFPA-96 requirements for replacement air shut-down upon fire extinguishing system activation. Dear Mr. Wiseman, The NFPA-96 Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations, Section 8.3.2, is the binding code requirement regarding replacement air (makeup air) shut-down during system activation. The Kitchen Mister System, and any other restaurant area fire suppression system for that matter, must comply with this requirement, It states: "8.3.2 When the fire-extinguishing system activates, makeup air supplied internally to the hood shall be shut off." The term "internally", as sited in this section, is intended to specify that only makeup air that is supplied directly into the hood itself (i.e., into the catch basin of the hood) is required to be shut off. Any makeup air supplied outside of the hood itself is not required to be shut off. I hope this information helps clarify the issue. I should point out that I am on the NFPA-96 Technical Committee and have a very good working knowledge of both the current document and its history.
