SYSTEM DESIGN
rGENERAL
The KITCHEN KNIGHT II Restaurant Fire Suppression System
may be used on a number of different types of restaurant
cooking appliances and hood and duct configurations. The
design information listed in this section deals with the limita-
tions and parameters of this pre-engineered system. Those
individuals responsible for the design of the KITCHEN KNIGHT
II system must be trained and hold a current PYRO-CHEM
certificate in a KITCHEN KNIGHT II training program.
NOZZLE COVERAGE AND
PLACEMENT
This section will provide guidelines for determining nozzle type,
positioning, and quantity for duct, plenum, and appliance
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)
(maximum side of 16 3/4 in. (42.6 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 3-1.
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 assem-
bly that will not interfere with the damper. Exceeding the maxi-
mum 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 determined
must be equally divided within the duct area.
CHART NO. 1
Ar••i 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
e. Figure 3-1a.

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 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 It
(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.

including drip boards. Exception: Tilt skillets and braising
pans may exceed the maximum of 6 sq ft (0.6 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

General Piping Requirements
Split piping and straight piping are both allowed on
a PCL-160, PCL-300 and PCL-460 system.
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. minimum piping
must be used up to the first split.
Maximum volume for 1/4 in. pipe between a nozzle
and the preceding tee is 410 mIs.
Maximum flow numbers for 1/4 in. pipe is 6.
Maximum number of elbows between a nozzle and
the preceding tee is 5.
Maximum of 25 elbows are allowed in the total
piping system.
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).
No traps are allowed in the piping network.
Pipe lengths are measured from center to center of
fittings.
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 additional 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 minimum,
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.
PCL-600 - Minimum of 960 ml and fourteen (14)
flow numbers required in total system. Of that
minimum, 120 ml and 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 location.
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 multiply
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.
