General Information
Introduction
The Buckeye Fire Equipment Kitchen Mister Fire
Suppression System is a pre-engineered wet chemical
restaurant fire suppression system as defined by the
NFPA-17A Standard for Wet Chemical Extinguishing
Systems. 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 MistorSystem. 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 (00G.) minimum to 120°F (490C.)
maximum.

that can protect a square or rectangular duct of unlimited
length and changes of direction with a maximum 150"
(381 cm) perimeter and a maximum one side length of
37-1/2' (95 cm) (square) and 50' (127 cm) (rectangular)
respectively. It can also protect a round duct with a
maximum circumference of 150" (381 cm) (47-1/2" (121
cm) maximum diameter). See Figure 3-1 and 3-2.
Ducts Larger than 150" (381 cm) Perimeter
For ducts with perimeters larger than 150' (381 cm),
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 Ducts
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 in
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.

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 (1.2 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. See Figure 3-7.

Note: These examples are typical and do not represent

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.

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 forthat appliance. In this
case, each. zone will be protected as an individual
appliance with respect to nozzle placement and aiming.

The protection of an appliance (such as a range) that has
a shelf that can interfere with a nozzle discharge can be
accomplished by either using the low proximity coverage
for that appliance or placing the nozzle in a position within
its stated limitation where the discharge pattern will not
be affected. Sample coverages for a range with a back-

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 (68 kg).
PIPING VOLUME CHART

pipe
1/2 in. (21.3 mm OD) 59.8 mL./ft. (196mL/m)
pipe
Example: 20 feet (6.1 m) of 3/8" (17.1 mm OD) pipe is
equal to 750 mL. of pipe volume [20 ft. (6.1 m) X 37.5
mUff. (123mUm) = 750 mL.).

BFR-15 15 2800" 2500
BFR-20 20 2800* 2500
* Total volume of 3/8" (17.1 mm OD) piping allowed on
the BFR-1 5 or BFR-20 Is 2500 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 than 360 mL.
The total system pipe volume shall not be less than
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" (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.

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 cookirg
surface area of less than 48° (122 cm) x 48" (122 cm)
must be protected by one (1) detector. The detector is :o
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) x48" (122 cm) must be protected by multiple
detectors, using one detector for every 48" (122 cm) x4B°
(122 cm) of continuous cooking area.
Exception: If a cooking appliance or appliances are
located under a duct opening where a detector has been az..
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. See Figure 3-26.
