Introduction
The Buckeye Fire Equipment Kitchen Mister Fire
Suppression System is a pie-engineered wet chemical
restaurant fire suppression system as defined by the
NFPA-1 7A 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 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. (00 C.) minimum to 120° F. (49° C.)
maximum.

Extinguishing Agent
The Kitchen Mister System utilizes a Potassium
Carbonate based extinguishing agent that is specifically
designed to extinguish grease laden fires such as those
found in commercial cooking areas. The recharge agent
is available in two different sized containers; the Model
BFR-5R (5 flow points of agent) and the Model BFR-IOR
(10 flow points of agent). For information on the proper
procedure for refilling the cylinder after system discharge,
refer to Chapter 5 of this manual.
WARNING
Goggles must be worn at all times when handling
extinguishing agent because it is very caustic in
nature. If agent gets in eyes, they must be flushed
with clear water for at least 15 minutes and a
physician contacted. If agent contacts skin, it
should be washed with cold water to prevent
irritation. When cleaning up agent discharged
around electrical devices or appliances, make sure
the power is off before proceeding with cleanup.
The agent is electrically conductive.

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 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 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
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" 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.
i
H
V BANK
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 PROTECTION
Figure 3-7.
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 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.

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 Figure 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.

* Total volume of 3/8" piping allowed on the BFR-15
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 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.
When the discharge piping is split, no nozzles can
be installed before the split.
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).

Buckeye Shielded Cable Installation Guidelines
OVERVIEW
Buckeye Shielded Cable (Patent Pending) is flexible conduit with a 1/16" stainless steel cable core that can be used for
all system inputs and outputs (fusible link line, gas valve line, and remote pull station line) instead of using conduit and
corner pulleys.
Note: If Buckeye Shielded Cable is not used for system controls, a combination of Buckeye Shielded Cable and 1/2"
EMT conduit with corner puIleys or just 1/2" EMT conduit and corner pulleys are also approved.
In general, Buckeye Shielded Cable is attached at one end to the System Releasing Module with a Buckeye Shielded
Cable Interface, run to where it needs to be terminated (hood, gas valve, or pull station), and connected at the other
end with another Buckeye Shielded Cable Interface. See Figure 4-5.
The Shielded Cable Interface holds the outer flexible conduit and allows the 1/16" stainless steel cable to pass through.
It connects to any standard 1/2" conduit type connection fitting, such as a corner pulley, or conduit connector.
