The following chapter will cover the proper design of the Buckeye Fire Equipment Kitchen Mister Fire Suppression System. It is divided into three sections: Nozzle Coverages and Placements Piping Limitations Detector Placement Design 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 Dealer. Buckeye Fire Equipment is not responsible for systems installed or maintained by personnel that are not factory trained and Authorized. NOZZLE COVERAGE, PLACEMENT AND AIMING This section will give detailed guidelines for determining nozzle type, positioning, and aim point 'for appliance, plenum, and duct protection. Duct Protection It is not necessary to shut down or damper the exhaust fan for the system to, function properly. It is recommended that the exhaust fan be left on during system discharge to help distribute the extinguishing agent throughout the ductwork. Ducts - 50" Maximum Perimeter Nozzle: N-1LP (1 Flow Point) Coverage: Unlimited length with: 50" Maximum Perimeter with a longest side of 16-3/4" for rectangular ducts and 12-1/2" for square ducts or 50" Maximum Circumference (maximum• diameter of 16") for round ducts. Placement: Centered in duct opening, from 1-6" into the duct opening. - Aim point: Center of duct. The Model N-i LP nozzle is a one flow point nozzle that can protect a square or rectangular duct with a maximum 50" perimeter and a maximum 7one side length of 12-1/2" (square) and 16-3/4" (rectangular) BPBFR.TM - Nozzle: N-2W (2 Flow Point) Coverage: Unlimited length with: 150' Maximum Perimeter with a longest side of 50" for rectangular ducts and 37-1/2" for square ducts or 150" Maximum Circumference (maximum diameter of 47-1/2") for round ducts. Placement: Centered in duct opening, from 0-6" into * the duct opening. Aim point: Center of duct. The Model N-2W nzzle.is a two (2) flow point nozzle that cart protect a square or rectangular duct with a maximum' 150' perimeter and a maximum one side length, of 37-1/2" (square) and 50" •(rectangular). respectively. It can also protect a round duct with a maximum circumference of 150" (47-1/2" maximum diameter). See Figure 3-1 and 3-2.

VIEW OF DUCT CROSS-SECTIONAL AREA Figure 3-2. Proper Duct Nozzle Placement- Ducts Larger than 150" Perimeter For ducts with perimeters larger than 150", more than one Model N-2W nozzle must be used. When using multiple Model N-2W nozzles to protect a• single duct, the cross sectional area of the duct must be divided into equal symmetrical areas. Each nozzle must then be installed in the center of the area it is protecting and aimed directly into the duct opening. No cross sectional area can exceed the single nozzle coverage. Transition Ducti. Protection of any non-standard duct should be discussed and agreed upon with the local authority having jurisdiction before proceeding with any system installation. Typically, transition ducts are protected ih the following manner. Larger to Smaller Duct Transitions To determine the proper coverage for ducts that have a larger opening into the plenum than the final exhaust duct, measure the perimeter of the duct half way between the largest and smallest cross sectional areas. The nozzle will be located as per standard duct coverage at the duct/plenum interface, rather than at the point of measurement, and pointed into the duct, aimed at the center of the final duct opening. See Figure 3.3. ERIJS 1 "WAII r T4RANS TION Figure 3.3.. Proper Measurement And Nozzle Placement For Larger To Smaller Transition Ducts. Smaller to Larger Duct Transitions To determine the proper coverage for ducts that have a smaller opening into the plenum than the final exhaust ULEX 6885 ULC-EX 6885 August 1, 2008 duct, measure the perimeter of the final exhaust duct. The nozzle will be located . as per standard duct coverage at the duct/plenum interface and aimed at the center of the duct opening. See Figure 3.4. PERIMETEA.J. MEASUREMENT Figure A. Proper Measurement And Nozzle Placement For Smaller To Larger Transition Ducts. Upper I Lower Plenums When protecting exhaust hoods with multiple risers (upper / lower plenums), each riser must be protected as an individual duct. See Figure 3.5. - . . . Figure 3.5. Upper I Lower Plenum Protection- Electrostatic Precipitators Ventilation systems that utilize electrostatic precipitators require duct protection above and below the precipitator. Standard duct nozzles are used for this . application. See Figure 3.6. Figure 3.6. Electrostatic Precipitator Protection Plenum Protection Nozzle: N-1HP (1 Flow Point) Coverage: Length: 12 feet max. Width: 4 feet max. Placement: See Figure 3.7. Aim point: See Figure 3.7. BPN: BFR-TM Chapter 3— System Design Page 3 - 3 Revision 2 The Model N-1 HP nozzle is a one (1) flow point nozzle that can protect a plenum (either single bank or V-bank) of 12 feet in length and 4 feet in width per nozzle. Larger plenums must be divided into. 12 foot sections, with each section protected with a separate nozzle. See Figure 3-7. Plenum: V-bank Nozzle Placern.?!!! The nozzle must be located at the center of the V-bank width and down 1/3 of the vertical height, within 6 inches of the end of the plenum or plenum module and aimed down the length of the plenum. See Figure 34. Plenum: Single Filter Bank Nozzle Placement The nozzle must be located at a pbint that is 2" from the back edge of the filter and 1/3. of the vertical height of the filter, within 6 inches off the end of the plenum or plenum module and aimed down the length of the plenum. See Figure 3-7. V 1/2W NO V BANK lmH______ INGLE BANK Figure 3-7. Model N-i HP 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 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 long plenum should be divided into two 8 foot zones, with a nozzle protecting each, as opposed to a 12 foot zone and a 4 foot zone. 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. RANGE.

ULEX 6885 ULC-EX 6885 BPN: BFR-TM 'August 1, 2008 - - Chapter 3— System Design Page 3 - 11 Revision 2 F11 PIPING LIMITATIONS This section contains detailed piping limitations that are necessary to design the piping network for The Buckeye Fire Equipment Kitchen Mister Fire Suppression System. Because the system is of the pre-engineered type, maximum and minimum piping parameters have already been established for each cylinder size. No variations to these limitations are allowed under the UL Listing. 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.. PIPING TERMINOLOGY Split Piping: The main supply piping from the cylinder enters the "bull side" of a Tee and directs the supply in two directions. The main supply can ONLY be split once in any piping system. See FigürC 3-25.. . . •. Straight Piping: •The main supply piping from the cylinder enters all Tees from the "run side" of the Tee, with branch lines attached to the "bull side". See Figure 3-25. STRAIGHT PIPING Spur Pima Figure 3-25. Split and Straight Piping Arrangements PIPING VOLUME CHART Allowable Pipe Sizes Volume Per foot 3/8 in. pipe 37.5 mL.Ift. 1/2 in. pipe 59.8 mL./ft. Example: 20 feet of 3/8' pipe is equal to 750 mL of pipe volume (20 ft. X 37.5 mL/ft. = 750 mL.). MAXIMUM PIPING PER CYLINDER SIZE Max. Pipe Cylinder Max. Max.

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 Piping Requirements All piping must be either 3/8" or 1/2". Split piping and straight line piping are allowed on all systems as long as the total system. piping parameters are not exceeded. Whn the discharge piping is split, no nozzles can be installed before thq split: The maximum number of elbows allowed per system are: BFR-5: 20 elbows maximum BFR-1 0/15/20: 25 elbows maximum The maximum nurnber.of. elbows between any two nozzles is five (5). SUPPLY + \BRNICN UNES CAN ALSO BE ENTERING Spur ONCE 'BULL SIDE* OF TEE BPN: BFR-TM ULEX 6885 ULC-EX 6885 August 1, 2008 Chapter 3— System Design Page 3-12 Revision 2 The maximum vertical rise of the supply line is 10 feet, 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. B. 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. 9. 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, 10. 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. 11. For the BFR-15 and BFR-20 only, the maximum - • . • volume of piping between .the nozzle nearest, the • . • -. supply line from one branch to .the closest nozzle from the next branch shall not exceed 500 mL. 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 Eaóh 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' into ductwork. Cookina Aoøliance Detector Placement Each cooking appliance with a continuous cooking surface area of less than 48" x 48" 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" x 48" must be, protected by multiple detectors, using one detector for every 48" x 48" of continuous cooking area. Exception: If a cooking appliance or appliances are Iodated under a duct opening where a detector has been mounted, it i nbt necessary to utilize an additional detector as lang the duct detector is not more than 12" into the duct opening.
