CHAPTER I
GENERAL iNFORi►iiATION
INTRODUCTION
The PYRO -CHEM® KITCHEN KNIGHT® II Restaurant Fire
Suppression System is of the pre- engineered type as
defined by NFPA -17A Standard for Wet Chemical
Extinguishing Systems and NFPA -96 Standard for the
Installation of Equipment for the Removal of Smoke and
Grease -Laden Vapors from Commercial Cooking Equipment.
The system is designed to provide fire protection for restau-
rant cooking appliances, hoods, and ducts. Installation and
maintenance of the system must conform to the limitations
detailed in this manual and be performed by an Authorized
PYRO -CHEM KITCHEN KNIGHT 11 dealer.
The PYRO -CHEM KITCHEN KNIGHT iI System utilizes a
wet chemical agent specifically designed to suppress restau-
rant cooking area fires. The system provides automatic actu-
ation and can be manually actuated through a remote
mechanical pull station. Upon actuation, the system
discharges a pre- determined amount of agent to the duct,
plenum, and cooking appliances. The agent acts to suppress
fires in three ways:
1. The chemical chain reaction causing combustion is inter-
rupted by both the agent itself and the resulting steam
formation.
2. The agent cools the fire bringing it below auto - ignition
temperature.
3. The agent reacts with hot grease forming a soap -like
layer (saponification) that helps prevent the escape of
combustible vapors, thus preventing re- ignition.
The shutdown of all sources of fuel and electric power that
produce heat to all equipment protected by the system is
required upon system actuation. It is recommended that
make up or supply air fans, integral to the exhaust hood(s)
being protected, should be shut down upon system actua-
tion. Exhaust fan(s) in the ventilation system should remain
on during system discharge as they assist the dispersion of
chemical through the ventilating system. The system is UL
Listed with or without exhaust fan shutdown.
The KITCHEN KNIGHT II and the KITCHEN KNIGHT
Restaurant Fire Suppression System are compatible as long
as separate installation guidelines are followed per each
system design manual. Exception: The actuation limitations
for the KITCHEN KNIGHT 11 system may be utilized for the
KITCHEN KNIGHT system. Also, control heads, prior to
Model No. 3, may be utilized on KITCHEN KNIGHT iI
systems, provided that the limitations used with those control
heads are followed.
Temperature Limitations
The operating temperature range of the PYRO -CHEM
KITCHEN KNIGHT II System is 32° F. (0° C.) minimum to
120° F (49° C.) maximum.

CYLINDERS & VALVE
The PYRO -CHEM KITCHEN KNIGHT If System has available
four different size cylinders: Models PCL -160 (P /N 553163),
PCL -300 (P /N 551194), PCL -460 (P /N 551193), and PCL -600
(P /N 551196). Cylinder sizes are expressed in terms of extin-
guishing agent capacity (i.e., the PCL -300 uses 3.0 gallons
(11.4 L) of extinguishing agent). The cylinder is manufactured,
tested, and meets DOT requirements. Cylinders come pre - filled
with extinguishing agent and are charged with dry nitrogen to a
pressure of 225 psig @ 70° F (15.5 bar @ 21 °C). Cylinder
and valve assembly dimensions are shown in Figure 2 -1a.

CHAPTER 111
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 11 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.
Chapter 3 — System Desigr
Page 3 -1
REV 4
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 -1 a.
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.

Transition Ducts — The protection of non - standard ducts
should be reviewed by the authority having jurisdiction.
PYRO -CHEM KITCHEN KNIGHT li recommends that transi-
tion ducts be protected as follows:
a_ Transition ducts — larger to smaller
In cases where the ductiplenum 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
mca =uremcnr was raKc11), u- itered under the final
exhaust duct opening. See Figure 3-1c.

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.

REV 3
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 filter, 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 10 ft.
. (3.1 m) limitation is not exceeded. See Figure 3 -2.

The Model 1 L 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 dimension.
See Figure 3 -4b. Note: Nozzles must be placed at or below
the shelf, within the nozzle height limitations.

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.

Protection for tilt skillet or braising pans is to be based
upon the coverage limitations provided for deep fat fryer
protection. Coverage limitations are based on fryer sizes
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
generally utilize a hinged cover. Fryer protecti pans
on 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.
2. 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.

General Piping Requirements
1 Split Piping and straight piping are both allowed
on a PCL -160, PCL -300 and PCL -460 system.
2. PCL -600 systems must use split Piping only, with
no nozzle located before the Split, and with a
maximum of 14 flow points per side. 1/2 in. mini-
mum piping must be used up to the first split.
3. Maximum volume for 1/4 in. pipe between a
nozzle and the preceding tee is 410 mis.
4. Maximum flow numbers for 1/4 in. pipe is 6.
5- Maximum number of elbows between a nozzle
and the preceding tee is 5.
6- Maximum of 25 elbows are allowed in the total
piping system.
7. Maximum difference in elevation between the tank
outlet and any nozzle, or the tank outlet and the
highest or lowest horizontal pipe run, is 10 ft-
(3.1 m).
8. No traps are allowed in the piping network.
9. Pipe lengths are measured from center to center
of fittings.
10. The internal equivalent length volume of fittings
does not have to be considered as part of the total
pipe volume.
11 • 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.
12. Elbow(s) or swivel adaptors located at the nozzles
do not have to be counted in the 25 elbow maxi-
mum requirement.
13. Reducing bushings are allowed when reducing to
a smaller pipe size -
14. Additional piping requirements when protecting a
range, wok, or a fryer:
I 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 tour (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 mis. /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.
