CHAPTER III
SYSTEM DESIGN
This section will cover the proper design of the Pyro-Chem
Restaurant Fire Suppression System. It is divided into four
(4) sections:
1. Nozzle Coverage and Placement.
2. Cylinder Sizing.
3. Piping Limitations.
4. Detector Requirements.
Each of these sections must be completed before attempting
any installation.
SECTION 1
Nozzle Coverage and Placement
This section will provide guidelines for determining nozzle
type, positioning, and quantity for duct, plenum, and appli-
ance protection.
A. Duct Protection
The following three (3) nozzles have been developed for the
protection of exhaust ducts:
1. Model NL -D1.
2. Model NL -D2.
3. Model NL -D3.
Each nozzle is approved for use with the exhaust fan damp-
ered, undampered with the fan on, or undampered with the
fan off. It is not required that the fan be shut down or the
exhaust duct be dampered for the system to operate proper-
ly. Each nozzle is approved to protect exhaust ducts of
unlimited length.
I. Model NL -D1
The Model NL -D1 nozzle is a one (1) flow point nozzle de-
signed for the protection of exhaust ducts. One (1) or two (2)
Model NL -D1 nozzles can be used on a single duct branch.
A single Model NL -D1 exhaust duct nozzle can protect a
square or rectangular duct with a maximum perimeter of 50
inches and a maximum one -side length of 17 inches. It can
also protect a round duct with a maximum circumference of
50 inches and a maximum diameter of 16 inches (see
Figure 3-1). The nozzle must be installed on the centerline .
of the duct and aimed directly into the duct opening (see
Figure 3-2).
Two (2) Model NL -D1 exhaust duct nozzles can protect a
square or rectangular duct with a maximum perimeter of 84
inches and a maximum one -side length of 34 inches. They
can also protect a round duct with a maximum circumfer-
ence of 84 inches and a maximum diameter of 26.5 inches.
When two (2) Model NL -D1 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 (see Figure 3-2.1).
2. Model NL -D2.
The Model NL -D2 nozzle is a two (2) flow point nozzle
designed for the protection of exhaust ducts. Only one (1)
Model NL -D2 nozzle can be used on a single duct branch.
A single Model NL -D2 exhaust duct nozzle can protect a
square or rectangular duct with a maximum perimeter of
75.5 inches and a maximum one -side length of 25 inches. It
can also protect a round duct with a maximum circumfer-
ence of 75.5 inches and a maximum diameter of 24 inches
(see Figure 3-1). The nozzle must be installed on the cen-
terline of the duct and aimed directly into the duct opening
(see Figure 3-2).
3. Model NL -D3.
The Model NL -D3 nozzle is a three (3) flow point nozzle de-
signed for the protection of exhaust ducts. One (1) or two (2)
Model NL -D3 nozzles can be used on a single duct branch.
A single Model NL -D3 exhaust duct nozzle can protect a
square or rectangular duct with a maximum perimeter of 100
inches and a maximum one -side length of 33 inches. It can
also protect a round duct with a maximum circumference of
100 inches and a maximum diameter of 31.75 inches (see
Figure 3-1). The nozzle must be installed on the centerline
of the duct and aimed directly into the duct opening (see
Figure 3-2).
Two (2) Model NL -D3 exhaust duct nozzles can protect a
square or rectangular duct with a maximum perimeter of 150
inches and a maximum one -side length of 66 inches. They
can also protect a round duct with a maximum circumfer-
ence of 150 inches and a maximum diameter of 47.5 inches.
When two (2) Model NL -D3 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 (see Figure 3-2.1).

B. Plenum Protection
The Model NL -A nozzle is a one (1) flow point nozzle that
has been developed to protect the plenum section of the
exhaust hood. Only one (1) Model NL -A nozzle can be used
on a single plenum branch. A single Model NL -A can protect
a plenum (with single or V -Bank filters) with rectangular
dimensions of 8' x 4' or less. Larger plenums can be protect-
ed by dividing the hazard area so that each nozzle protects
an area of 8' x 4' or less (see Figure 3-3).
The nozzle(s) must be located at the center of the V -Bank
width or centered between the filter width when used with a
single bank filter plenum. It must be within 4" of the wall it is

8.3 Electrostatic Precipitator Coverage.
Some restaurant ventilating systems may utilize an electro-
static precipitator to facilitate the removal of grease laden
vapor. These precipitators are typically located at or near the
base of the exhaust duct. If protection for electrostatic pre-
cipitators is required by the local "authority having jurisdic-
tion," the following guidelines should be followed.
1) Nozzle Placement
Ducts having electrostatic precipitators are protected by
using the appropriate duct nozzle(s) (as per Chapter 3,
Section 1) above the precipitator and a Model NL -UB Nozzle
for the precipitator itself.
The duct nozzle(s) must be installed above the precipitator
and aimed in the direction of air flow. One (1) Model NL -UB
nozzle must be used to protect the precipitator. The nozzle
is to'be centered 10 to 26 inches before the precipitator with
its discharge point aimed at the center of the precipitator.

SECTION 2
CYLINDER SIZING
After determining the number and type of nozzles required to
protect the duct, plenum, and cooking appliances, the total
number of system flow points can be determined. The sum
of all required nozzles' flow points is used to determine the
size and quantity of cylinders required.
MAXIMUM CYLINDER FLOW POINTS
Flow Points Cylinder
8 PCL -240
13 PCL -350
20 PCL -550
For systems requiring more than twenty (20) flow points, any
combination of cylinders can be used provided the total flow
point requirements are met.
EXAMPLE
If a system requires twenty-six (26) flow points, the fol-
lowing combinations of cylinders can be used:
1 x PCL -550 and 1 x PCL -240 (28 FP total)
2. 2 x PCL -350 (26 FP total)
NOTE
Cylinders cannot be manifolded together. Each cylinder
must be piped separately.

SECTION .3
PIPING LIMITATIONS
Pyro-Chem Restaurant Fire Suppression System piping limi-
tations are divided into two categories; Main Supply Line
Piping Limitations and Branch Line Piping Limitations.
1. Main Supply Line Piping.
The main supply line is a run of pipe from the cylinder to the
hazard area. In general, it is a straight run of pipe that runs
through tees. Branch piping is connected to the side outlet
of these tees.
The main supply line of the Pyro-Chem Restaurant Fire
Suppression System utilizes either straight line or split pip-
ing to simplify system installation.
Straight line piping is distinguished by the fact that the main
supply line is a straight run of pipe that flows through tees.
When straight line piping is used, the main supply line can-
not run into the branch of a tee.
Split piping is distinguished by the fact that the main supply
line runs into the branch of the first tee, splitting the main
supply line in two. When split piping is used, no branch pip-
ing can be connected to the main supply line before it is
split. In split piping systems, the entire main supply line,
including both sides of the split, cannot exceed the piping
limitations outlined in this chapter. In addition, the equivalent
lengths of the main supply line is not required to be bal-
anced.

2. Branch Line Piping.
Branch piping is used to connect the discharge nozzles to
the main supply line. This piping is connected to the side
outlet of main supply line tees. The last branch is connected
to an elbow at the end of the main supply line. There are
seven (7) types of branch piping:
1. One (1) Nozzle Duct Branch.
2. Two (2) Nozzle Duct Branch.
3. One (1) Nozzle Plenum Branch.
4. One (1) Nozzle Appliance Branch.
5. Two (2) Nozzle Appliance Branch.
6. Three (3) Nozzle Appliance Branch.
7. Four (4) Nozzle Range Branch.
UNDERSTANDING EQUIVALENT
PIPING
Piping limitations in this chapter are given in both linear and
equivalent lengths.
Linear piping is the actual length of straight pipe used on
either the main supply line or a branch.
Equivalent piping is equal to the total linear pipe used on
either the main supply line or a branch lus the equivalent
length of any fittings used on either the main supply line or a
branch. See Figure 3-15.
Equivalent Piping = (Linear Piping) +
(Total Equivalent Length of Fittings
Used)
All pipe fittings develop a pressure loss which can be equat-
ed to the loss through a specific length of straight pipe. This
loss is the equivalent length of the fitting. See Table 3-1.
Table 3-1. Pipe Fitting Equivalent Lengths In Feet.
An example of the total equivalent piping calculation for a
typical branch is illustrated by Figure 3-15.
NOTE
The only acceptable types of piping which can be used
with the Pyro-Chem System are black pipe, stainless
steel, or chrome plated pipe. Galvanized pipe cannot
be used.

7. Four (4) Nozzle Range Branch.
NOTE: A range branch is any branch that contains NL -F1.25
nozzles only. Any branch that contains NL -F1.25 nozzles in
combination with any other nozzle(s) is considered an appli-
ance branch.
When using the PCL -240, the total of all duct, plenum, appli-
ance, and range branch piping cannot exceed 25 linear feet
and 55 equivalent feet.
When using the PCL -350, the total of all duct, plenum, appli-
ance, and range branch piping cannot exceed 35 linear feet
and 100 equivalent feet.
When using the PCL -550, the total of all duct, plenum, appli-
ance, and range branch piping cannot exceed 45 linear feet
and 125 equivalent feet.
Branch piping limitations are applicable to all cylinder sizes
(i.e., PCL -240, PCL -350, and PCL -550). All branch piping
must be 3/8" diameter black, chrome plated, or stainless
steel pipe.

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.
1. Exhaust Duct(s).
Each exhaust duct must have at least one (1) detector
installed in the center of the duct entrance or at a maximum
of 12 feet into the duct, centered. See Figure 3-19.
2. Cooking Appliance(s).
Each cooking appliance with a continuous cooking surface
not exceeding 48" x 48" shall be protected by one (1) detec-
tor. Cooking appliances with a continuous cooking surface
exceeding 48" x 48" shall be protected by one (1) detector
Chapter 3 — System Design

Rev. 1
per 48" x 48" cooking area. Detectors used for cooking appli-
ances must be located within the perimeter of the protected
appliance 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" into the duct opening. If two (2) appliances 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" into the duct
opening. See Figure 3-19.
