CHAPTER III
SYSTEM DESIGN
This chapter will detail the basic information necessary for
proper design of the PYRO-CHEM KITCHEN KNIGHT II
Restaurant Fire Suppression System. However, before
attempting any installation, it is necessary to attend a
Factory Certification Training Class and become Certified to
design the PYRO-CHEM KITCHEN KNIGHT II Restaurant
Fire Suppression System. The chapter is divided into three
(3) sections:
Nozzle Coverage and Placement
Piping Limitations
Detector Requirements
Each of these sections must be completed before attempting
any installation.
NOZZLE COVERAGE AND
PLACEMENT
This section will provide guidelines for determining nozzle
type, positioning, and quantity for duct, plenum, and appli-
ance protection.
Duct Protection
It is not required that the fan be shut down or the exhaust
duct be dampered for the system to operate properly.
All duct protection is UL listed without limitation of maximum
duct length (unlimited length). This includes all varieties of
ductworks both horizontal and vertical including ducts that
run at angles to the horizontal and ducts with directional
bends.
Duct protection requires that a nozzle be positioned to
discharge into the duct. Two nozzles are available for duct
protection.
The Model IL Nozzle, Part No. 551026, is a one (1) flow
nozzle. A single IL nozzle is capable of protecting square or
rectangular ducts with a maximum perimeter of 50 in.
(127 cm), with the diagonal being a maximum of 18 3/4 in.
(47.6 cm). It can also protect a round duct with a maximum
diameter of 16 in. (40.6 cm).
The Model 2D duct nozzle, Part No. 551038, is a two (2)
flow nozzle. A single 2D nozzle is capable of protecting
square or rectangular ducts with a maximum perimeter of
100 in. (254 cm), with the diagonal being a maximum of
37 3/8 in. (94.9 cm). It can also protect a round duct with a
maximum diameter of 31 7/8 in. (81 cm).
When two (2) 2D duct nozzles are used to protect a single
duct, the cross sectional area of the duct must be divided
into two equal symmetrical areas. The nozzle must then be
installed on the centerline of the area it protects and aimed
directly into the duct opening.
The nozzle(s) must be installed on the centerline of the duct,
with the tip located 0 to 6 in. (15.2 cm) into the opening, and
aimed directly into the duct opening. See Figure 3-1a.
In installations where a UL listed damper assembly is
employed, the duct nozzle can be installed beyond the 6 in.
(15.2 cm) maximum, to a point just beyond the damper
assembly that will not interfere with the damper. Exceeding
the maximum of 6 in. (15.2 cm) in this way will not void the
UL listing of the system.

Modularizing Ducts
DUCT SIZES GREATER THAN 100 IN. (254 cm) PERIMETER]
Ducts over 100 in. perimeter must be modularized using
2D nozzles (Part No. 551038)
No round duct option available
Follow the design chart to determine maximum module
size for each 2D nozzle
When determining number of nozzles required, it is some-
times an advantage to check the chart using the shortest
side as Side 'A" and then recheck it using the longest side
as Side "A'. This comparison may reveal a need for a
lesser quantity of nozzles one way versus the other way.
When working with Chart 1, the quantity of nozzles deter-
mined must be equally divided within the duct area.
CHART NO. 1

SIDE B"
When working with Chart 2, one half of the quantity of nozzles
determined must be equally positioned in the top half of the
area of the duct and the remaining half of the nozzles must be
positioned in the bottom half of the duct area.
Example: The duct to be protected has a Side "A" of 40 in.
and a Side "B" of 60 in. Referring to the design chart, this
duct requires 4 nozzles. One half of 4 = 2. Therefore, 2
nozzles must be equally positioned in each of the two duct
areas. See Figure 3-lb.

Transition Ducts - The protection of non-standard ducts
should be reviewed by the authority having jurisdiction.
PYRO-CHEM KITCHEN KNIGHT II recommends that transi-
tion ducts be protected as follows:
a. Transition ducts - larger to smaller
In cases where the duct/plenum interface opening is
larger than the final exhaust duct, measure the perime-
ter/diameter of the duct halfway between the largest
and smallest section (or the average perimeter/diame-
ter). The nozzle is to be located within 0-6 in. (15.2 cm)
of the duct/plenum interface (not at the point where the
measurement was taken), centered under the final
exhaust duct opening. See Figure 3-1c.
c. Multiple risers
In cases of multiple rises, each riser is protected as an
individual duct. See Figure 3-1e.

Plenum Protection
The Model 1H nozzle, Part No. 551029, is a one (1)flow
nozzle used for plenum protection. A single 1 H nozzle can
protect a plenum (with single or V-bank filters) 10 ft. (3.1 m)
long by 4 ft. (1.2 m) wide. Dividing the length into sections
equal to or less than 10 ft. (3.1 m) in length and positioning
a nozzle at the start of each section can be done to protect
longer plenums.

On V-bank plenums, the nozzle(s) must be located at the
center of the V-bank width, 1/3 of the vertical height of the
filters. On single filter bank plenums, the nozzle must be
located 2 in. (5.1 cm) from the back edge of the fiter, 1/3
down from the vertical height. For either application, the
nozzle must be located within 6 in. (15.2 cm) of the end of
the plenum (or module) and aimed directly down the length of
the plenum. The nozzles may point in the opposite directions
as long as the entire plenum area is protected, and the loft.
(3.1 m) limitation is not exceeded. See Figure 3-2.
Appliance Protection
Note: When protecting appliances which are larger than
single nozzle coverage, multiple nozzles can be used.
Larger appliances can be divided into several modules, each
equal to or smaller than single nozzle coverage. Exception:
Fryers must not exceed a maximum of 864 sq. in.
(5574 sq. cm).

The Model 1L nozzle, Part No. 551066, is used for low prox-imity small range protection. This nozzle is a one (1) flow
nozzle. The range can be equipped either with or without
a backshelf. Either type requires the same nozzle require-
ments. The nozzle must be located 22 in. (56 cm) from either
end of the hazard area centered from left to right. It must be
13 in. to 24 in. (33 to 61 cm) above cooking surface, and
aimed at a point one half the distance of whatever the height
dimension of the nozzle is. When determining nozzle and aim
point locations, both measurements are to be taken from the
same end of the hazard area. Example: The nozzle is
mounted 20 in. (51 cm) above the cooking surface. The aim
point from the edge of the hazard would then be 10 in. (25
cm) which is one half the nozzle mounting height dmension.
See Figure 3-4b. Note: Nozzles must be placed at or below
the shelf, within the nozzle height limitations.

3. Larger Burner Range (784 sq. in. (5085 sq. cm) maxi-
mum, 28 in. (71 cm) longest side maximum)
One nozzle is available for large range protection: High
proximity.
The Model 2L nozzle, Part No. 551027, is used for high
proximity large range protection. This nozzle is a two (2)
flow nozzle. When using high proximity protection, the
range cannot be under a backshelf. This nozzle must be
located 34 in. to 48 in. (86 to 122 cm) above the cooking
surface, and aimed directly down within the mounting area,
based on the hazard size, as described in the Nozzle
Positioning Chart. See Figure 3-5.
Example: A four burner range has a hazard size of 20 in.
(51 cm) in length and 27 in. (69 cm) in width. Follow down
the Range Length column in the Nozzle Positioning Chart
until you come to 20 in. (51 cm). Continue down this
column until the correct width appears in the width column.
When the width of 27 in. (69 cm) is arrived at, read across
to the radius column to determine the size of radius
allowed, for positioning of the nozzle, from the hazard area
centerline. In this example, the correct radius is 3 in. (8 cm)
The nozzle can be aimed straight down anywhere within a
3 in. (8 cm) radius of the hazard area centerline.

including drip boards. Exception: Tilt skillets and braising
pans may exceed the maximum of 6 sq. ft. (.6 sq. m)
total when modularizing. Tilt skillets and braising pans
generally utilize a hinged cover. Fryer protection nozzles
are to be placed toward the front of the appliance to
minimize the potential for the tilt skillet or braising pan
cover to interfere with the nozzle discharge. See Figure

Fryer - Multiple Nozzle Protection
Fryers exceeding the coverage of a single nozzle can be
divided into modules. Each module must not exceed the
maximum area allowed for a single nozzle. However, when
utilizing multiple nozzle protection, the longest side allowed
for a fryer with drip board can be used, regardless of
whether the fryer has a drip board or not.
The maximum size fryer that can be modularized is
864 sq. in. (5574 sq. cm).
Design requirements for multiple nozzle fryers are broken
down as follows:
If the fryer includes any dripboard areas, measure both
the internal length (front to back) and width of the frypot
portion. Then measure the internal length and width of
the overall hazard area including any dripboard areas.
Determine the area of both the frypot and the area of
the overall vat by multiplying corresponding length and
width dimensions.
Divide the frypot or overall vat into modules, each of
which can be protected by a single nozzle, based on the
maximum dimension and area coverage of the nozzle as
specified in 'Design Chart.'
If the module considered does not include any portion
of the dripboard, use only the maximum frypot area
and maximum dimension listed in the 'Design Chart."
If the module considered includes any dripboard
areas, use both the maximum frypot area and dimen-
sion listed in the Design Chart", and the maximum
overall area and dimension listed in the "Design
Chart."
3. None of the maximum dimensions may be exceeded. If
either the maximum frypot or the overall sizes are
exceeded, the area divided into modules will need to be
redefined with the possibility of an additional nozzle.

PIPING LIMITATIONS
Once the nozzle placement and quantity of tanks has been
determined, it is necessary to determine the piping configu-
rations between the tank and the nozzles. This section
contains the guidelines and limitations for designing the
distribution piping so that the wet chemical agent will
discharge from the nozzles at a proper flow rate. These limi-
tations must also be referred to when selecting the mounting
location for the tanks.
The maximum pipe lengths are based on internal pipe
volume. Each size tank is allowed a minimum and maximum
total volume of piping, calculated in milliliters.
There is no need to distinguish between what portion of the
piping is supply line and what portion is branch line. Only the
total volume of the complete piping network has to be
considered.

1/4 in. pipe = 20.5 mls./ft.

The internal equivalent length volume of fittings
does not have to be considered as part of the total
pipe volume.
When utilizing different size pipe in the system,
the largest size must start first and the addi-
tional pipe must decrease as it approaches the
nozzle.
Elbow(s) or swivel adaptors located at the nozzles
do not have to be counted in the 25 elbow maxi-
mum requirement.
Reducing bushings are allowed when reducing to
a smaller pipe size.
Additional piping requirements when protecting a
range, wok, or a fryer:
PCL-160 - Minimum of 239 ml and one (1) flow
number required in total system. Of that mini-
mum, 180 ml must be utilized at or before the
range, wok, or fryer.
PCL-300 - Minimum of 300 ml and four (4) flow
numbers required in total system. Of that mini-
mum, 239 ml and two (2) flow numbers must be
utilized at or before the range, wok, or fryer.
PCL-460 - Minimum of 660 ml and ten (10) flow
numbers required in total system. Of that mini-
mum, 180 ml and two (2) flow numbers must be
utilized at or before the range, wok, or fryer.

Design Steps
Step No. 1 Determine number of flow points required based
on duct size, plenum size and type, and size of
all appliances.
Step No. 2 Determine size and quantity of tanks required.
Refer to the chart in 'General Piping
Requirements to determine the maximum
amount of flow numbers allowed per each tank
size.
Step No. 3 Layout nozzles, piping diagram, and tank loca-
tion. Determine pipe lengths as accurate as
possible. Make certain maximum number of
elbows is not exceeded. Note: Tanks cannot be
manifolded together. Each tank must have a
separate piping network.
Step No. 4 Add all the lengths of each pipe run and multi-
ply by the mls./ft. listed in the Volume Chart. If
the sum falls within the acceptable range noted
in general Piping Requirements, that pipe size
is acceptable. If the calculated volume is too
large, recalculate the volume using the ml per
foot of a smaller pipe size. Pipe sizes can be
mixed but Rule No. 11 of the General Piping
Requirements must be followed.
Step No. 5 Check to make certain minimum volumes, maxi-
mum volumes and maximum volume allowed
between first nozzle and last nozzle is not
exceeded (Tank Chart). Check each rule in
"General Piping Requirement" to make certain
none have been exceeded. If any requirement is
exceeded, change to a different pipe size and
recalculate.

DETECTOR PLACEMENT
Detectors are required over cooking appliances and in the
duct(s) of protected ventilation hoods. Detectors shall be
located in the plenum area of the ventilation hood.
Exhaust Duct(s).
Each exhaust duct must have at least one (1) detector
installed in the duct entrance, located in the air stream of the
cooking vapors at a maximum of 12 feet (3.7 m) into the
duct. See Figure 3-23.
Figure 3-23.
006884PC
NOTICE
When gas appliances are used and the flue gases from
the burner are exhausted into the duct, the detector must
be kept out of the air stream of these exhaust gases.
These gases can be very hot and could actuate the
system unnecessarily.
Duct openings that are long and narrow or large enough
to require multiple duct nozzles may require additional
detectors.
Electrostatic Precipitator.
If an electrostatic precipitator is located at or near the base of
the exhaust duct, it is necessary to locate a detector below the
precipitator, at the base of the duct, and also locate one in the
duct, just above the precipitator. See Figure 3-23a.
When installing the detector bracket and system conduit, make
certain they do not interfere with the operation of the
precipitator.
Figure 3-23a.
000268
Cooking Appliance(s).
Each cooking appliance with a continuous cooking surface
not exceeding 48 in. x 48 in. (122 x 122 cm) shall be
protected by one (1) detector. Cooking appliances with a
continuous cooking surface exceeding 48 in. x 48 in. (122 x
122 cm) shall be protected by one (1) detector per 48 in. x
48 in. (122 x 122 cm) cooking area. Detectors used for cook-
ing appliances must be located above the protected appli-
ance toward the exhaust duct side of the appliance. The
detector should be located in the air stream of the appliance
to enhance system response time.
If a cooking appliance is located under a duct opening where
a detector has been mounted, it is not necessary to utilize
an additional detector provided the duct detector is not more
than 12 in. (31 cm) into the duct opening. If two (2) appli-
ances are located under a duct opening where a detector
has been mounted, it is not necessary to utilize an additional
detector provided the duct detector is not more than 12 in.
(31 cm) into the duct opening. See Figure 3-24.

CAUTION
Precautions must be taken when handling and trans-
ferring wet agents as they are caustic in nature.
Goggles must be worn at all times. If any agent gets
into the eyes, they should be flushed with clean water
for 15 minutes and a physician contacted. If any agent
contacts the skin, it should be flushed with cold water
to prevent irritation. The agent is electrically conduc-
tive. Care must be taken to thoroughly clean up any
agent discharged around electrical appliances before
