OVERVIEW OF SYSTEM DESIGN.
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.

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.

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.

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.

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

up to a maximum diameter of 30". The nozzle must be
located 30" to 48" above the bottom of the wok and
positioned anywhere over the cooking area. The nozzle
must be aimed at the center of the cooking area. See
Figure 3-23.
ADoliances Reauirinq Multiple Nozzles
(Module Protection)
Appliances that exceed the coverage of a single nozzle
can be protected with multiple nozzles. The appliance
hazard area must be divided into equal sized modules
with each module not exceeding the maximum coverage
allowed for a single nozzle. Each nozzle is then located
and aimed within the module it is protecting, following
the limitations stated for single nozzle coverage. See
Figure 3-24 for an example of module protection.

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.

Example: 20 feet of 3/8' pipe is equal to 750 mL of
pipe volume (20 ft. X 37.5 mL/ft. = 750 mL.).

BFR-20 20 2800* 2500
* Total volume of 3/8" piping allowed on thf 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.
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).

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. See Figure 3-26.
