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 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 (00C.) minimum to 120°F (490C.)
maximum.

Buckeye Shielded Cable
As an alternative to using conduit and corner pulleys to
connect the fusible link system, gas valve, and/or remote
pull station to the Systems Releasing Module, the
Kitchen Mister System utilizes Buckeye Shielded Cable
to perform this function. Buckeye Shielded Cable is 1/16"
(0.16 cm) stainless steel cable encased in a protective,
flexible conduit. See Figure 2-14.
Buckeye Shielded Cable requires no conduit or corner
pulleys, as the name implies, provided it is installed in
accordance with the guidelines set forth in this manual.

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.

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.
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 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-shelf are shown in Figures 3-13 and

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).

1/2 in. (21.3 mm OD) pipe 59.8 mL./ft. (196mL/m)
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
mL./ft. (123mLJm) = 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-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" (17.1 mm OD) or 1/2"
(21.3 mm OD),
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 cocking
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. See Figure 3-26.

Subject: Gyro Cooker Protection
To: Authorized Buckeye Kitchen Mister" Distributors
To Whom It May Concern:
Underwriters' Laboratories Inc. (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,

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.
Kind Regards,
William Vegso
