SYSTEM DESIGN
INTRODUCTION
This chapter introduces the designer and installer to the process whereby Range Guard s Wet
Chemical Systems are designed. It outlines the process. introduces the limitations imposed on design
by system hardware, as well as those mandated by performance considerations.
As the designer becomes familiar with this material, they should remember that analysis and design
is a careful, step-by-step process. All steps must be followed, none can be omitted, and all unique
aspects of a given application must be taken into account if the resulting fire-suppression system is
to deliver the desired results.
All systems must be designed in accordance with the latest edition of NFPA Standard 17A. 'Standard
for Wet Chemical Systems", and other applicable NFPA standards. All configurations are UL and
ULC/OR.D 1254.6 Listed to Underwriters Laboratories 300. 1994 Edition, unless otherwise noted.
3-2 DESIGN PROCEDURE
This section covers the design aspects of the Karbalov systems. It contains all the necessary
information to design a complete system including nozzle placement. detector placement. cylinder
sizing, piping limitations and awdliary hardware.
3-2.1 General Design Procedure
Analysis and design should be approached as a methodical process. and performed step-by-step.
I Only when all the steps are followed is the resulting system likely to perform as desired. If any step
is omitted, it is probable that the system will not function as well as it should. The steps in the
analysis and design process are:
I Hazard analysis
Nozzle selection, number and location
I
. Cylinders (Number, size, and location of cylinders)
Detector selection
Piping layout
I • Awdliary requirements
3-2.1.1 HAZARD ANALYSIS
I Sketch out the kitchen exhaust hood and appliances, taking note of the path of egress for remote pull
station location, discuss with owner the placement of cylinders and control heads. automatic fuel
I shut down device locations, and any power shutdowns required.
Consult NFPA 17A and 96 for design guidelines. Record the.following and include in your sketch:
I
. Size of exhaust hood(s) and exhaust duct opening(s)
Size and fuel type of appliances (cake note if open flames are sufficiently separated from
combustible cooking media)
I
. Size of gas line(s) feeding appliances
. Building or local alarms
System Design I
Make up air or auxiliary equipment
Are the correct hand portable fire extinguishers present or are additional extinguishers required
3-2.1.2 NOZZLE SELECTION AND LOCATION
Select the number and type(s) of nozzle(s) needed and locate them so that the entire hazard is
covered. Use the coverage.distribution specifications for each nozzle type to determine the number of
discharge nozzles required to deliver the necessary quantity of wet chemical given nozzle placement
appropriate to the hazard.
3-2.1.3 CYLINDER DETERMINATION (NUMBER, SIZE, AND LOCATION OF CYLINDER(S))
Determine the number of nozzles required, whether additional agent or nozzles may be needed, and
select the cylinder which will supply the needed amounts wet chemical. After determining the quantity-
and types of wet chemical needed to control the hazard itself, determine whether any special
conditions necessitate additional wet chemical quantities and/or nozzles. For example, it may be
necessary to adjust the agent discharge rate in order to offset the effects of ventilation, or it may be
necessary to screen openings in an enclosure to prevent wet chemical leakage through those
openings.
3-2.1.4 DETECTOR SELECTION
Detector selection will depend on the response speed required, the probable heat level and rate of
spread of the fire. The detectors sense the heat energy released by the combustion of fuel and oxygen.
Upon detection of a fire. the detection system sends a signal to the system control head(s) which
initiates the wet chemical discharge. The most commonly used detectors are the:
I. Fixed-temperature thermo-buib or fusible link
2. Fixed-temperature rate-compensated thermostat
3-2.1.5 PIPING LAYOUT
Careful piping layout assures that the agent reaches the distribution nozzles appropriately, and that
piping parameters are not exceeded. These parameters involve pipe lengths, the number of elbows,
and other factors such as the allowable distances (equivalent/feet) from Cylinder and Valve Assembly.
These parameters are discussed in detail in the design examples in Paragraph 3-8.
3-2.1.6 AUXILIARY REQUIREMENTS
Controls are required to turn off force draft ventilation systems, fuel (or combustible-liquid) pumps
convevors. and so on.

3-3 DESIGNING FOR APPLIANCE PROTECTION
To determine the number and size of cylinders required for each system. the term flow number is
used. A flow number is assigned to each type of nozzle used in the Range Guard system and is a
relative indicator of the discharge rate of each nozzle. Refer to Table 3-1 for coverage on a specific
appliance.
ADP nozzles have a flow number of one. The ADP nozzle is used to protect a varier of cooking
appliances. These appliances are solid fuel charbroilers, upright broilers, low proximity Split Vat
Deep Fat Frvers. griddles and chain broilers. Additionally, the ADP nozzle is used to protect the duct
and plenum areas of the hood.
The F' nozzle has a flow number of two and is used to protect fryers and lava rock broilers
I
The 'R nozzle has a flow number of one and is used to protect a burner range.
The GRW nozzle has a flow number of one and is used to protect a radiant charbroiler or a wok.
I The LPF nozzle has a flow number of two and is used to protect a deep fat fryer requiring a low nozzle
height.
I
The LPR nozzle has a flow number of one and is used to protect a four burner range requiring a low
nozzle height (eq. range with a backshelf or an integral broiler).
I
The DM nozzle has a flow number of three and is used to protect the mesquite log charbroiler.
After completing your design for locating nozzles over the cooking appliances to be protected.
determine the total of the flow numbers required, including those for the plenum and exhaust duct(s).
This will render the required cylinder size for the total number of flow points.
Note: Protection of combination appliances requires a seperate nozzle for each appliance.
I
While nozzles can be placed anywhere in the areas denoted in the following sections,
caution should be exercised regarding placement and aiming of nozzles from the back of ft CAUTION the appliance toward appliance operators.
I
System Design
3-3.1 Nozzle Height
Measurement of the nozzle heights are to be from the tip of the nozzle to the top of the appliance
When using the grid style nozzle locaLion the nozzle height is measured from the nozzle tip to the
aiming point. When using perimeter style nozzle location the nozzle height is measured from the
nozzle tip straight down to the appliance surface.
EXCEPTION: Woks are measured to the inside bottom of the wok.
3-3.2 Nozzle Aim
Correct aiming of the appliance nozzles is extremely important to the performance of the system. Care
should be taken to insure accurate aiming and that the conical spray from the nozzle is not
obstructed. Aiming must comply with the parameters outlined in the design section of this manual.
3-3.3 Hazard Area
The hazard area is the actual size of the portion of the appliance which can be used for cooking. The
physical width of an appliance does not represent the width of the hazard area. The thickness to the
appliance wall must be deducted to arrive at the hazard area width.
Ak All appliances being protected must be shut off automatically upon system actuation. CAUTION ft
The appliance area is the size of the appliance that includes the cooking area (fry pot or vat) and the
integral drip board area.

3-5 MODULE. PROTECTION (MULTIPLE NOZZLES)
For appliances that exceed single nozzle coverage, multiple nozzles can be used to protect that
appliance bv modularizing (dividing up into smaller sections) the larer appliances hazard area.
Exception: for deep fat fryers the maximum protected area for a single vat is 6 ft.2 (1.9 m2).
For a deep fat fryer that exceeds single nozzle coverage, multiple F nozzles can be used by dividing
the hazard area into smaller modules that meet the limitation of a single nozzle.
3-5.1 Example - Module Protection of Fryers With Dripboards Less Than 1 in. (25 mm)
Each module that the larger hazard area is divided into must not exceed 24 in x 24 in. 1610 mm x 610 runi) and appliance area of 24 in. x 25 in. (610mm x 635 mm) if a drip board is included. A
single F nozzle is then used to protect each of these smaller modules. See Figure 3-23. The nozzle
shall be located anywhere within the perimeter of the hazard area. and aimed at the midpoint of the
hazard.

3-6.1.1 DUCTS
The ADP nozzle. P.N B12001 1. is used for protection of the exhaust ductwork.
The duct cross section can be any shape. not including obstructions (i.e.. round, square. or
I
rectangu1ar) and the duct itself can be of unlimited length. In accordance with NF'PA 96, the exhaust
fan should be left running at the time of system discharge. This will help to remove smoke and other
airborne materials and gases from the hazard area in the event of a fire. Check with the Authority
I
Havin Jurisdiction for local requirements. A damper. if present. should be left open at system
discharge. However, if the damper is closed, the system designer must insure that additional nozzles
are required
3-6.1.1.1 Protection of Ducts 0 to 50 inches in Perimeter
One ADP nozzle. RN B 120011. is required for protection of a duct with a perimeter up to 50-inches
(refer to Figure 3-29). Length of duct is unlimited.
The nozzle is located at the geometric center of the cross-sectional area that it is protecting. and is
located in the duct within six inches of the entrance.
Note: Al! Range Guard systems are listed by UL and ULC for use with the exhaust fan either on or
off when the system is discharged.

Designing For Large Ducts
Large Ducts (Perimeters Greater than 100 Inches)
For ducts larer than 100 in. (2540 mm) perimeter, the total perimeter of the duct must be divided
by 50. If the answer contains a decimal (or fraction), it must be rounded-up to the nearest whole
number. That will provide the number of nozzles necessary for proper protection of the duct. The
diagonal dimension inozzle to corner of duct) of each module must not exceed 11.78 inches (297
mm). if this diagonal dimension is exceeded. additional module divisions must be added until the
diagonal dimension is not exceeded. A nozzle must then be centered in each module" (refer to
Figure 3-3 IL
EXAMPLE
You have a duct with a perimeter of 156 in. (3962 tom).
Take the perimeter: 156 and divide it by the maximum allowable perimeter of a single nozzle: 50.
156/50 = 3.12
Round the 3.12 up to the next highest integer: 4. Four nozzles are required to protect this duct.
A2 + B2 = C2 Where A is length. B is width and C is diagonal.
Each section' of the duct is l8L x 15W.
182 + 152 = c2
324 + 225 = 549
The square root of 549 is 23.43 inches (23.43 549): therefore. the diagonal of each module is 23.43
inches. One-half of 23.43 is 11.7 1, which is the measurement from the nozzle to the corner of the
duct. Our maximum allowable diagonal is 11.78 inches. as stated above.

Alternative Method: Ducts 0 to 75 Inches in Perimeter
Two ADP nozzles can be used in ducts with a perimeter of 0 up to 75 inches (1651 to 1905 mm). The
ratio of the longest to shortest perimeter sides shall not exceed 3 to 1.
One of these nozzles is pointed into the duct and the other is pointed into the plenum.
The tip of the upper nozzle. of the pair of nozzles required for each duct. shall be positioned in the
center of the duct opening and above the plane of the hood-duct opening between 1 in. (25 mm and
24 in. (610 mm(. The duct length is unlimited See Figure 3-32.
Note: When a damper is present at the hood duct opening. the duct nozzles are to be located above
the damper and should not interfere with the operation of the damper.
Note: All Range Guard systems are listed by UL and LJLC for use with the exhaust fan either on or

3-6.1.2 SPECIAL CONFIGURATIONS
3-6.1.2.1 Protection of Electrostatic Precipitators
Electrostatic precipitators (ESP) are designed to remove smoke and other airborne contaminants
from the airstream flowing through exhaust ductwork. ESPs are used in restaurant kitchen exhaust
systems as a means of pollucion control They are not intended to replace grease filters as the primal-,; means of grease extraction. ESPs obstruct exhaust airflow and therefore require nozzle coverage in
addition to a nozzle(s) protecting the ductwork.
Exhaust ductwork using ESPs require ADP nozzle(s). The ADP nozzle(s) must be located centrally in
the ductwork and should be aimed at the middle of the ESP. Disrribution piping to the ADP nozzle
located above the ESP and the ADP nozzle aimed at the precipitator must not interfere with the
function of the ESP unit. Scc Figure 3-35.

3-8 PIPING REQUIREMENTS
1 Range Guard systems do not require balanced piping to achieve proper distribution of wet chemical
to all nozzles. Balanced piping is not necessary because a liquid has no difficulty in turning corners
I or changing directions Range Guard nozzles come equipped with permanent predetermined orifices.
This means that the liquid will be delivered in the exact quantities necessary to the duct. plenum and
appliance hazards as required.
All pipe shall be schedule 40 (standard veiiht) black steel. Pipe may be chrome plated. Galvanized
1 pipe shall not be used. All pipe and fittings must be made tight without pipe dope or thread sealant.
Pipe fittings shall be standard weight steel. cast iron. malleable iron or ductile iron. Galvanized
I fittings shall not be used. Branch line connection and individual nozzle connections may be made by
using either the outlet or the run of a tee.
3-8.1 Stainless Steel Tubing and Fittings
Stainless steel tubing may be used on all Range Guard systems. Fittings may be stainless steel
compression or stainless steel flare types. Bending of tubing using mandrels is permissible.
3-8.2 Pipe Sizing
Pipe sizes are determined by the total number of flow numbers running through a particular piece of
pipe. This is the flow demand for that portion of the system.
Note: It is not permissible to drop pipe diameters below the required value. For example. using 1/2-
inch pipe to flow 18 flow numbers is not permissible. However, increasing pipe diameter is
acceptable (i.e.. using 1-inch pipe to flow 18 flow numbers) providing the system complies
with internal pipe volume limitations.

3-8.3 General Rules
A maximum of 100 equivalent ft. (30.5 m) but not more than 40 linear ft. (12.2 m) of 1/4-in, pipe
may be used from each branch line.
The highest point of the system shall not exceed 12 ft. (3.7 mi above the cylinder outlet.
The vertical rise of a branch line above the supply line shall not exceed a maximum of 4 ft.
(1.2 m).

3-8.4 Discharge Line Volume Limitations
There is a discharge line volume limitation in Range Guard systems. Discharge line volume is the
total volume of all pipe. tubing. and fittings used in single or multiple cylinder systems.
To measure discharge line volume, it is necessary to measure all pipe length from the center of one
fitting to the center of the next fitting and multiplY by the volume-per-foot factor given in Table 3-32
and Table 3-33

3-3.4.4 DETECTOR
Detectors using Range Guard approved fusible link detectors are required over cooking appliances
and in the ducts of kitchen cooking equipment per NFPA 17A and NFPA 96.
For protection of the duct, a detector must be centered either flush with the hood-duct opening or in
the duct but not more than 12 feet (3,7 ml downstream from where the duct is connected to the hood.
When mounted in the duct, the detector should be oriented so that the b:ackei does not shield the
link from the hot air stream. and the fusible link is centered in the duct.
Maximum dimension per detector is 54 in. x 54 in. 1372 mm x 1372 mm).
Appliances having a surface area larger than 54 in. x 54 in, (1372 mm x 1372 mm) require additional
detectors. When a cooking appliance is under the hood-duct opening, the appliance is protected by
the detector mounted at the hood-duct opening or 12 in. (305 mm) maximum into the duct. An
addiiona1 detector is not needed to protect that appliance.
A temperature survey must be performed at all locations where detectors will be installed. The survey
must be conducted under maximum cooking or appliance cleaning conditions in order to determine
the optimum exhaust air flow locations and to record the peak temperatures that are expected to
occur.
Once the survey is completed:
Select the lowest temperature rated detector that can be used.
Make sure the maximum exposure temperature of the link exceeds the maximum temperature
obtained from the survey.
Make sure links are located in the exhaust air now, not in dead air spaces. This will provide the
fastest detector response.
Note: Care must be taken not to install links directly in the exhaust flow of appliance flue gas
