r
This manual is intended for use with ANSUL� R-102T"'
Restaurant Fire Suppression Systems.
Those who install, operate, recharge, or maintain ihese fire sup-
pression systems should read this entire manual. Specific sec-
tions will be of particular interest depending upon one's
responsibilities.
Design, installation, recharge, and maintenance of the system
must conform to the limitations detailed in this manual and per-
formed by an individual who attended an ANSUL training pro-
gram and became trained to install, recharge, design, and main-
tain the ANSUL system.
Fire suppression systems are mechanical devices. They need
periodic care. Maintenance is a viial step in the performance of
your fire suppression system. As such it must be performed in
accordance with NFPA 96 (Standard for the Installation of
Equipment for the Removal of Smoke and Grease-Laden Vapors
from Commercial Cooking Equipment) and NFPA 17A (Standard
on Wet Chemical Extinguishing Systems) by an authorized
ANSUL disiributor. To provide ma�cimum assurance that the fire
suppression system will operaie effectively and safely, mainte-
nance must be conducted at six-month intervals, or earlier if the
situation dictates. Twelve-year maintenance must include agent
tank hydrostatic testing.

DESIGN AND APPLICATION
The ANSUL R-102 Restaurant Fire Suppression System is
designed to provide fire protection for restaurant cooking appli-
ances, hoods, and ducts. It is a pre-engineered group of inechan-
ical and electrical components for installation by an authorized
ANSUL distributor. The basic system consists of an ANSUL
AUTOMAN regulated release assembly which includes a regulat-
ed release mechanism and a liquid agent storage tank housed
within a single endosure. Nozzles, detectors, cartridges, liquid
agent, fusible links, pulley tees, and pulley elbows are supplied in
separate packages in the quantities needed for each fire suppres-
sion system arrangement.
The system provides automatic actuation; or it can be actuated
manually through a remote manual pull station. The system is also
capable of shutting down appliances at system actuation. For
appliance shutdown requirements, refer to the current version of
NFPA 17A, "Standard For Wet Chemical Extinguishing Systems;'
and NFPA 96, "Standard For Ventilation Control and Fire
Protection of Commercial Cooking Operations."
Additional equipment includes: remote manual pull siation,
� mechanical and electrical gas valves, and electrical switches for
automatic equipment and gas line shut-off. Accessories can be
added, such as alarms, warning lights, etc., to insiallations where
required.
The R-102 system suppresses fire by spraying the plenum area,
the filters, cooking surfaces, and the exhaust duct system with a
predetermined flow rate of ANSULEX Low pH Liquid Fire
Suppressant. When the liquid agent is discharged onto a cooking
appliance fire, it cools the grease surface, and reacts with the hot
grease (saponification) forming a layer of soap-like foam on the
surface of the fat. This layer acts as insulation between the hot
grease and the atmosphere, thus helping to prevent the escape of
combustible vapors.
Exhaust fans in the ventilating system shouid be left on. The forced
draft of these fans assists the movement of the liquid agent
through ihe ventilating system, thus aiding in the fire suppression
process. These fans also provide a cooling effect in the pienum
and duct after the fire suppression system has been discharged.
The system is UL listed with or without fan operation.
Make up or supply air fans, integral to the exhaust hood(s) being
protected, shall be shut down upon system actuation.
Along with the fire suppression system, the total system design
must include hand portable fire extinguisher(s) located within the
cooking/restaurant area that can be used to manually suppress a
fire that may be burning in an unprotected area. Class K e�ctin-
guisher(s) must be provided for hazards where there is a potential
for fires involving combustible cooking media (vegetable or animai
oils and fats). Refer to NFPA 10, "Standard For Portable Fire
Extinguisher;' for additional information.
UL LISTING
The R-102 Restaurant Fire Suppression System has been tested
and is listed by Underwriters Laboratories, Inc. as a pre-engi-
neered system. The system is in compliance with ULTest
Standard 300. These tests require extinguishment of fires which
are initiated in deep fat fryers, ranges, griddles, char-broilers,
woks, upright broilers, chain-broilers, filters, plenum chambers,
hoods, and ducts after pre-loading each appliance with a pre-
scri6ed amount of cooking grease. Each fire is allowed to progress
to maximum intensity before the fire suppression system is
actuated.

DEFINITION OFTERMS
� Actuation Gas Line: Piping and/or stainless steel braided hose
I assemblies from the ANSUL AUTOMAN Regulated Release
� Assembly which supplies high pressure nitrogen or carbon dioxide
to the Regulated Actuator Assembly for multipie-tank system actu-
ation.
AgentTank: A pressure vessel containing the liquid agent.
ANSUL AUTOMAN Regulated Release Assembly (Electrical):
An assembly which contains the regulated release mechanism,
agent tank (ordered separately), expellant gas hose, solenoid, and
electric switch within a metal enclosure. The enclosure contains
knockouts to facilitate component hookups.
ANSUL AUTOMAN Regulated Release Assembly (Mechani-
cal): An assembly which contains the regulated release mecha-
nism, agent tank (ordered separately), and expellant gas hose
within a metal enclosure. The enclosure contains knockouts to
facilitate component hookups.
Authority Having Jurisdiction: The "authority having jurisdiction"
is the organization, office, or individual responsible for "approving"
equipment, an installation, or a procedure. The phrase "AUthority
Having Jurisdiction" is used in a broad manner since jurisdictions
and "approval" agencies vary as do their responsibilities. Where
public safety is primary, the "authority having jurisdiction" may be
a federal, state, local, or other regional department or individual
such as a fire chief, fire marshal, chief of a fire prevention bureau,
labor department, health department, building official, electrical
inspector, or oihers having statutory authority. For insurance pur-
poses, an insurance company representative may be the "author-
ity having jurisdiciion:' In many circumstances the property owner
or his designated agent assumes the role of the "authoriTy having
jurisdiction;" ai government installations, the commanding officer
or departmental official may be ihe "authority having jurisdiction"
� Blow-Off Cap: A siliconized rubber or metal cap which covers the
Iend of the nozzle to protect the nozzle tip and minimize cooking
� grease migration into the nozzle orifice.
Branch Line: The agent distribution piping which extends from the
supply line to the nozzle(s).
� Bursting Disc: A disc installed in the tank adaptor which mini-
mizes the remote chance of siphoning of the agent into the dis-
charge piping during extreme temperature variations.
. Cartridge: A hermetically sealed, steel pressure vessel containing
nitrogen or carbon dioxide gas used to pressurize the agent tank.
Cooking Appliance: Includes fryers, griddles, ranges, upright
broilers, chain broilers, natural charcoal broilers, or char-broilers
(elecYric, lava rock, gas-radiant, or mesquite).
Cooking Area: Cooking area is defined as the maximum surface
that requires protection. Each type of appliance has a defined
. cooking area with parameters that vary for each appliance. For
example, the cooking area for a griddle is the entire flat cooking
surface, while a fryer may have hvo areas that need consideration,
. depending on whether the fryer has a dripboard or not.
Conduit Offset Assembly: A pre-formed piece of conduit which
can be instailed between the ANSUL regulafed release and the
conduit to allow the wire rope for the detection, gas valve and
remote manual pull station to be installed in a more convenient
manner.

tection is available: full hood continuous protection and group pro-
tection. Overlapping protection is in addition to appliance specific
coverages.
Plenum: The space enclosed by the filters and the portion of the
hood above the filters.
Pre-engineered System: NFPA 77A defines a pre-engineered
system as one which has "...predetermined flow rates, nozzle
pressures, and quantities of liquid agent:' The R-102 system, as
prescribed by UL (Underwriter's Laboratories), has specific pipe
sizes, mauimum and minimum pipe lengths and numbers of fii-
tings, and number and iypes of nozzies. The hazards protected by
this system are also specifically limited as to type and size by UL
based upon actual fire tests. All limitations on hazards that can be
protected and piping and nozzle configurations are contained in
the R-102 installation and maintenance manual which is part of
the UL listing.
Pulley Elbow: A device used to change the direction of the wire
rope which runs between: the regulated release mechanism and
the detectors, the regulated release mechanism and the mechan-
ical gas valve, and/or the regulated release mechanism and the

REGULATED RELEASE ASSEMBLY (MECHANICAL)
The ANSUL AUTOMAN Regulated Mechanical Release Assembly
(Part No. 429853) contains the regulated release mechanism,
expellant gas hose for agent tank hookup, and enclosure knock-
outs to facilitate instailing actuation piping; expellant piping; detec-
tion system; and additional equipment. This regulated release
assembly is used in single, double, and multiple-tank systems and
must be mounted to a rigid surface. The release mechanism can
be used to interconnect both the actuation and expellant gas lines
as required per system design. The regulator is designed to allow
� a constant flow of gas into the tank at 110 psi (7.6 bar) when the
system is actuated. The agent tank must be ordered separately.
In single, double, and multiple-tank systems, the provided expel-
lant gas hose connects the agent tank to the bottom outlet of the
regulator. In double and multiple-tank system configurations, the
back outlet of the regulator is used as an expellant gas feed for
one additional tank-enclosure or tank-bracket hookup. The enclo-
sure contains the required knockouts to facilitate this connection.
If a pressure switch is to be attached to the regulator, addiiional fit-
tings are required.
The tank is mounted within the enclosure. The tank contains an
adaptorRube assembly with a burst disc union. The burst disc
helps prevent siphoning of the agent up the pipe due to significant
temperature fiuctuations in the area where the tank is located. The
� tank is stainless steel and, under normal conditions, requires
hydrostatic testing every twelve years.
The detection and additional equipment required per system
design are connected to the release mechanism. The enclosure
contains knockouts to facilitate detection and additional hookups.
The system can be actuated automatically or manually. Automatic
actuation occurs when a fusible link within the detection system
separates in a fire condition. Manual actuation of the system
occurs when personnel pull on the remote manual pull station
pull ring.

DETECTORS
The detector consists of three basic components: the bracket, Iink-
age, and fusible link. (Fusible links are not included and must be
ordered separately.) The bracket holds the entire assembly to the
mounting surface. The linkage is used to support the fusible link.
The fusible link is designed to separate at a specific temperature
and release the wire rope, thereby actuating the regulated release
mechanism.
. The scissor sryle detector allows the wire rope to be strung com-
pletely through the detection system conduit and brackets first and
the detector linkage assemblies are then clipped on later.
. The detector consists of hvo types of assemblies:
� The Terminal Detector (Part No. 435546) includes a test link and
is placed last in a series of detectors. This detector is sometimes
referred to as the end-of-line detector and is thus named because
it is at the point at which the wire rope "terminates;' or is anchored
at the detector bracket. Only one terminal detector is required per
detection system.
� The Series Detector (Part No. 435547) is any detector iocated in-
line behveen ihe regulated release assembly and the terminal
� detector.
� When using Part No. 435546 and 435547 detectors, a total of 15
detectors can be in one detection system: 14 series detectors, Part
� No. 435547 and 1 terminal detector, Part No. 435546.
� Note: Series Detector, Part No. 435547, is also available as Part
� No. 435548, 25/Pkg.

STAINLESS STEEL CABLE
The 1/16 in. stainless steel cable is run from the terminal detector,
through conduit, all series detectors and pulley elbows, and into
the regulated release mechanism trip lever. When any fusible link
separates, the tension on the cable is relaxed, and the trip lever
actuates the regulated release mechanism. The cable can also be
used for mechanical gas valves and remote manual pull stations.
The cable is available in 50 ft(15 m) (Part No. 15821) and 500 ft
(752.4 m) (Part No. 79653) lengths.
REMOTE MANUAL PULL STATION
The remote manual pull station (Part No. 434618 or 435960) is
made out of a molded red composite material. The red color
makes the pull station more readily identifiable as the manual
means for fire suppression system operation. The pull station is
compatible with the ANSUL Flexible Conduit. The molded manual
pull station should be mounted at a point of egress and posiiioned
at a height determined by the authority having jurisdiction. Trim
Fings, Part No. 427074 (pack of 10), are available.

In addition to eliminating the siphoning effect, the common in-line
burst disc assembly eliminates the possibility of one or more indi-
vidual discs located in the tank adaptor from failing to burst. The
assembly consists of a stainless steel body which houses the
burst disc. When utilizing this assembly in a manifolded system, it
is necessary to modify (remove) the burst disc located in all of the
R-102 tank adaptors in the system. The in-line burst disc assem-
bly is to be mounted as close to the tank outlet as possibie. After
system discharge, the assembly must be disassembled and a new

AGENT DISTRIBUTION HOSE AND RESTRAINING CABLE KIT
The Agent Distribution Hose and Restraining Cable Kit, Part No.
435982, consists of a 5 k(1.5 mj long Agent Distribution Hose, a
3 ft(0.9 m) long Restraining Cable, and a Restraining Cable
Hardware Package. The Agent Distribution Hose can be utilized
with castered cooking appliances with castered supports found in
commercial kitchens. The hose allows for movement of the appli-
ance for cleaning without having to disconnect any fire suppres-
sion system discharge piping.
Note: The Agent Distribution Hose is authorized for use with only
UL Listed ANSUL Wet Chemical Restaurant Fire Suppression
Systems.
SYSTEM DESIGN
The ANSUL R-102 Restaurant Fire Suppression System may be
used on a number of different types of restaurant cooking appli-
ances and hood and duct configurations. The design information
listed in this section deals with the limitations and parameters of
this pre-engineered system. Those individuals responsible for the
design of the R-102 system must be trained and hold a current
ANSUL certificate in an R-102 training program.
The R-102 and the PIRANHA systems use compatible agenis and
components, therefore, they may be used together for cooking
appliance, hood, and duct protection. The primary ANSUL
AUTOMAN Release can be either an R-102 or a PIRANHA
ANSUL AUTOMAN Release and can actuate up to two additional
R-102 or PIRANHA Regulated Actuators. In systems utilizing a
701 remote release, any combination of the maximum number of
regulated actuators can be used.
• Both systems must actuate simultaneously.
• Each system must be designed and installed per its appropri-
ate manual.
• Adjacent appliances requiring protection must be protected
with the same type of system, eiiher R-102 or PIRANHA,
unless the center-to-center spacing between the adjacent
' R-102 and PIRANHA nozzles is no less than 36 in. (91.4 cm).
When appliances are protected with R-102 nozzles, the hood
and connecting duct above those appliances cannot be pro-
tected with PIRANHA nozzles.
Mixing systems in a common plenum is not allowed.
One of the key elements for restaurant fire protection is a correct
system design. This section is divided into ten sub-sections: Noz-
zle Placement Requirements, Tank Quantity Requirements, Actu-
ation and Expellant Gas Line Requirements, Distribution Piping
Requiremenis, Detection System Requirements, Manual Pull Sta-
tion Requirements, Mechanical Gas Valve Requirements, Electri-
cal Gas Valve Requiremeots, Electrical Switch Requirements, and
Pressure Switch Requirements. Each of these sections must be
completed before attempting any installation. System design
sketches should be made of ali aspects of design for reference
during installation.
NOZZLE PLACEMENT REQUIREMENTS
This section gives guidelines for nozzle type, positioning, and
quantity for duct, plenum, and individual appliance protection. This
section must be completed before determining tank quantiry and
piping requirements.
Duct Protection — Single Noule
All duct protection is UL listed without limitation of maximum duct
length (unlimited length). This includes ail varieties of ductworks
both horizontal and vertical including ducts that run at angles to
the horizontal and ducts with directional bends.
The R-102 system uses different duct nozzles depending on the
size of duct being protected.

Example: Protection is required for a duct that has an "A" dimen-
sion of 8.0 in. (20 cm) wide and a"B" dimension of 55 ia (140 cm)
long.
Referring to the table in Figure 2, if the "A" dimension is 8.0 in. (20
cm), the "B" dimension must not exceed 58.5 in. (149 cm). In this
example, the "B" dimension is 55 in. (140 cm), therefore, this duct
can be protected with a three flow application.
� Read over from the 8.0 in. (20 cm) line on the table to the 7 W
Module column. At that point, the chart shows that the "B" module
� length for the 7 W nozzle can be 22.0 in. (56 cm). Center the 1 W
nozzle in that module. The 2W module can now be centered with-
in the remaining module.

• Follow the design chart to determine maximum module size for

• When determining number of nozzles required, it is sometimes
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

Transition Protection
Transitions are protected at a point in the transition where the
perimeter or the diameter is equal to or less than the maximum
size duct that can be protected. The nozzle(s) must be located in
the center of the area at that point, or center of the module pro-
tected when more than one duct nozzle is required. Note: Noules
to protect ducts with a transition that is more than 4 ft(72 m)
in height, will be required to be positioned in the opening of
the transition from the hood 2 to 8 in. (5.1 to 20.3 cm) into the
opening using standard duct nozzle design parameters. See
Figure 4.

Electrostatic Precipitator P�otection
Some restaurant ventilating ducts have an electrostatic precipita-
� tor installed at or near the base. These precipitators are generally
� small and are used to aid in the cleaning of ezhaust air.
.
Ducts with precipitators located at or near the base can be pro-
tected using duct nozzle(s) above the precipitator and 1/2N noz-
zle(s) (Part No.479334) for the precipitator.One 1/2N nozzle must
be used for each cell being protected. This nozzle tip is stamped
with 1/2N, indicating that it is a 1/2-flow nozzle and must be count-
ed as 1/2 flow number.
When protecting ducts equipped with precipitators, the duct noz-
zle(s) must be installed above the precipitator and aimed to dis-
charge downstream. If the area above the precipitator is a duct, the
nozzle(s) must be positioned according to duct protection guide-
lines. If the area above the precipitator is a transition, the transition
guidelines must be followed.
The i/2N nozzle (Part No. 419334) must be centered 10 to 26 in.
(25 to 66 cm) below the precipitator and aimed to discharge at the
center of each precipitator cell. However, if it is physically impossi-
ble to mount the nozzle at 10 to 26 in. (25 to 66 cm) due to pre-
cipitator placement, the nozzle may be mounted closer than 10 in.
(25 cm). See Figure 5.

Plenum Protection
The R-102 system uses the 1 W Nozzle (Part No. 419336) or the
1 N Nozzle (Part No. 419335) for plenum protection. The 7 W noz-
zle tip is stamped with 1 W and the 1N nozzle tip is stamped with
1 N, indicating they are one-flow nozzles and must be counted as
one flow number each. When protecting a plenum chamber, the
entire chamber must be protected regardless of filter length.
VERTICAL PROTECTION — GENERAL

One 1 W nozzle will protect 4 linear feet (1.2 m) of plenum. The
maximum distance from the end of the hood to the first and last
nozzle must be no more than 2 ft(0.6 m). After the first nozzle, any
additional nozzles must be positioned at a maximum of 4 ft(1.2 m)
apart down the entire length of the plenum.The plenum width must
not exceed 4 ft(12 m). (The 1 W nozzle can be used on single or
V-bank filter arrangements.) See Figure 6.

When protecting plenums with the 1 W nozzle, two options of cov-
erage are available:
Option 1: The 1 W nozzle must be on the center line of the single

For a plenum, either single or "V" bank, with a linear extension
longer than 10 ft(3.1 m), each bank may be protected using one

length of the plenum. See Figure 12. The nozzles may point in the
opposite directions as long as the entire plenum area is protected,
and the 10 k(3.1 m) limitation is not exceeded. See Figure 13. The
nozzle positioning shown in Figure 14 is not an acceptable method
of protection because the plenum area directly under the tee is not

Appliance Protection
The following pages detail types of appliance protection. Each
design requires several factors: correct nozzle choice, correct noz-
zle height above hazard, correct nozzle location and correct aim-
ing point.
Fryer — Single Noale Protection
1. Design requirements for fryers are broken down into rivo
types.
A. FRYERS WITHOUT DRIPBOARDS
If the fryer does not include a dripboard, measure the
internal depth (horizontal dimension from front to back)
and length of the frypot.
B. FRYERS WITH DRIPBOARDS
If the fryer includes any dripboard areas, measure both
the internal depth (horizontal dimension from front to
back) and length of the frypot portion, and then measure
the internal depth and length of the overall hazard area
including any dripboard areas.
2. Using Table, "Maximum Cooking Area Dimension — Single
Nozzle Fryer Protection;' determine which nozzle is needed
to proiect the fryer based on the maximum dimensions listed.
A. If the Fryer does not include a dripboard, use the maxi-
mum dimensions listed in the first column of the table to
select the correct nozzle.
B. If the fryer includes any dripboard areas, use both the
maximum frypot dimensions in the first column of the
table, and the maximum overall dimensions in the second
column of the table to select the correct nozzle. None of
the maximum dimensions in either column may be
exceeded.
3. If either the mauimum frypot or the overall sizes are exceed-
ed, an additionai nozzle(s) will be required. Refer to the mul-
tiple nozzle requirements.
Example: A fryer with a dripboard. The inside of the frypot without
the dripboard measures 18 in. in depth x 18 in. in length (46 cm x
46 cm) and the inside of the overall area including the dripboard
measures 18 in. in depth x 24 in. in length (46 cm x 61 cm). From
the Table "Maximum Cooking Area Dimension — Single Nozzle
FryerProtectian," either the 3N or the 290 nozzle should be select-
ed to protect the fryer, depending on the maximum nozzle height
above the fryer and the positioning requirements allowed. Refer to
app�opriate Figures.

Fryer — Multiple Noule Protection
Design Requirements:
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 dripboard can
be used, regardless of whether the fryer has a dripboard or not.
� The mauimum size fryer that can be modularized is 864 in.z
.(5574 cm2) or in terms of R, s ft2 (o.s m2).
1. Design requirements for multiple nozzle fryers are broken
down into lwo types:
2.
�
A. FRYERS WITHOUT DRIPBOARD(S)
If the fryer does not include a dripboard, measure the inter-
nal depth (horizontal dimension from front to back) and
length of the frypot. Then, multiply the depth and length to
obtain the area of the frypot in square inches.
B. FRYERS WITH DRIPBOARD(S)
If the fryer includes any dripboard areas, measure both the
internal depth and length of the frypot portion, and then
measure the internal depth and length 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 depih and length
dimensions.
Divide the frypot or overall vat into modules, each of which can
be protected by a single nozzle, based on the ma�cimum
dimension and area coverage of the noule as specified in
Table, "Maximum Cooking Area Dimension — Multiple Nozzle
Protection"
A. If the module considered does not include any portion of
the dripboard, use only the maximum irypot area and max-
imum dimension listed in ihe first column of the table io
select the correct nozzle.
B. If the module considered includes any dripboard areas, use
both the maximum frypot area and dimension listed in the
first column of the table, and the maximum overall area and

select the correct noule.
None of the maximum dimensions in either column may be
exceeded. If either the maximum frypot or the overall sizes are
exceeded, the area divided into modules will need to be rede-
fined with the possibility of an additional nozzle.
Options For Modularizing Fryers

FRYER WITH DRIPBOARO
Example: A fryer with a d�ipboard_ The inside vat wi�hout the drip-
board measu�es 18 in. in depth x 30 in. in length (46 cm. x 76 cm)
and the inside of the overall vat including the drip6oard measures
24 in. in depth x 30 in. in length (61 cm x 76 cm). Because the fryer
is 30 in. (76 cm) in length, it exceeds the coverage of a single
nozzle.
Dividing the length in half, each module now has an overall vat
dimension of 24 in. in depth x 15 in. in length (61 x 38 cm). From
the Table, "Maximum Cooking Area Dimension — Multiple Nozzle
Fryer Protection,"either the 3N or the 290 nozzle should be select-
ed to protect each fryermodule, depending on the maximum noz-
zle height a6ove the fryer and the positioning requirements
allowed. Refer to approp�iate Figures, 15 through ?9.

Multiple Noule Fryer Protection —Tilt Skillet / Braising Pan
Protection for tilt skillets or braising pans is to be based upon the
coverage limitations provided for deep fat fryer protection. Refer to
Section IV, DESIGN, starting on Page 4-10, for maximum fryer
nozzle coverages and maximum fryer nozzle height limitations.
. Although the maximum 6 ftz (0.6 m2) total s�rtace cooking area
requirement applies to fryer proiection, it does not apply to tilt skil-
lets or braising pans.
Each tilt skilleWraising pan protected module must not exceed the
fryer limitations for "MAXIMUM SIZE MODULE OVERALL WITH
DRIPBOARD" coverage per nozzle as described in Table on Page
4-11.
Tilt skillets and braising pans generally utilize a hinged cover. Fryer
protection nozzles are to be placed toward the front of the appli-
ance io minimize the potential For the tili skillet or braising pan
� cover to interfere with the nozzle discharge. See Figures 25 and
� 26.

� Griddle Protection 1 W(1-Flow) Nozzle - Low Proximity
Application
15 in. to 20 in. (38.1 cm to 50.8 cm) above the cooking surtace.
The low proximity 1-flow nozzle application for the protection of
griddles requires the 1 W nozzle, Part No. 419336.
The nozzle tip is stamped with 1 W indicating that this is a one-flow
nozzle and must be counted as one flow number.
When using the 1 W noule for low proximity griddie protection with
our without obstruction, the maximum length of the cooking sur-
Face to be protected must not exceed 26 in.(66.0 cm).The nozzle
must be centered at one end of the mauimum 26 in. (66.0 cm)
length, aimed along a centerline to a point 20 in. (50.8 cm) from
the end of the length, protecting a maximum width of 20.5 in.
(52.1 cm).
The 1 W nozzle tip must be positioned at or below the obstruction,
if present. The protected area begins at the point straight down
from the nozzle tip. The nozzle can be positioned above the edge
of the hazard area to be protected. See Figures 51 and 52.
Note: If the hazard area exceeds the single nozzle coverage list-
ed above, additional nozzles will be required. The additional noz-
zle can be positioned in front at high proximiiy or at the side at low
proximity.

Chain Broiler Protection
�The following listed protection guidelines can be applied to any
manufacturer's chain broilers, if the chain broiler meets the speci-
fied parameters. Chain broilers utilizing catalytic converters can
be protected from overhead using model specific protection iden-
tified in the "Specific Application by Model" section in System
Design. Or, they can be protected with standard 1 N nozzle hori-
zontal chain broiler protection with the nozzles positioned at either
end of the chain broiler openings. Refer to the Horizontal Chain
Broiler Protection section for specific design information.
Horizontal Chain Broiler Protection
The R-102 system can use hvo 1 N Nozzles (Part No. 419335) for
. horizontal chain broiler protection. The nozzle tip is stamped 1 N,
indicating that this is a one-flow nozzle and must be counted as
one flow number (total of two flow numbers for each chain broiler
being protected).
Two 1N nozzles are always needed for chain broiler protection
when the hazard area to be protected does not meet the
"Overhead Broiler Protection" requirements. The maximum inter-
nal size of the broiler is 43 x 31 in. (109 cm x 79 cm). The nozzles
must be positioned at each end of the enclosed cooking chamber
1 to 3 in. (2.5 to 7.5 cm) above the surface of the chain and a max-
imum distance of 4 in. (10 cm) away from the broiler opening. The
nozzles may be mounted at either corner as long as they are at
opposite ends of the chain broiler and positioned to discharge
. diagonally across the top of the chain. See Figures 53 and 54.

Overhead Chain Broiler Protection
. The R-102 system can use two 1 W Nozzles (Part No. 419336) for
overhead chain broiler protection. The nozzle tip is stamped with
1 W, indicating that this is a one-flow nozzle and must be counied
as one flow number.
Overhead protection is only available For chain broilers with
exhaust opening dimensions that are not less than 60% of the
internal broiler length and not less than 60 % of the internal broiler
width, to a minimum size of 12 in. x 12 in. (30.5 x 30.5 cm). Internal
broiler size can not be larger than 32 in. x 34 in. (81 x 86 cm).
When overhead protection is used, the nozzles must be centered
above ihe exhaust opening within 4 to 8 in. (10 to 20 cm) of each
other and they must be located 10 to 26 in. (25 to 66 cm) above
� the top of the broiler surface. See Figure 55.

The nozzles may vary in position as long as they are evenly
spaced from the exhaust center and are always 180° opposite of
each other. If the opening is not square, the nozzles must be posi-
tioned along the centerline, parallel to the longest side of the open-
. ing. See Figure 56.

Overhead Chain Broiler Protection (Continued)
Example No. 1- Internal broiler size is 24 in. long x 20 in. wide
(67 x 57 cm), with an opening of 16 in. x 16 in.
(40.6 x 40.6 cm).
To determine minimum opening size, multiply the
internal length and the internal width by 0.6:
Length of opening - 24 in. x 0.6 = 14.4 in.
(61 cm x 0.6 = 36.6 cm)
Width of opening - 20 in. x 0.6 = 12.0 in.
(51 cm x 0.6 = 30.5 cm)
The minimum allowable opening for overhead protec-
tion would be 14.4 in. x 12.0 in. (36.6 x 30.5 cm).
This example would be acceptable for overhead pro-
tection.
Example No. 2- Internal broiler size is 30 in. long x 24 in. wide
(76 x 61 cm) with an opening of 22 in. x 12 in.
(56 x 30 cm).
To determine minimum opening size, multiply internal
length and internal width by 0.6:
Length of opening - 30 in. x 0.6 = 18.0 in.
(76cmx0.6=45.7cm)
Width of opening - 24 in. x 0.6 = 14.4 in.
(61 cm x 0.6 = 36.6 cm)
Minimum allowable opening for overhead protection
would be 18 in. x 14.4 in. (45.7 x 36.6 cm).
Because this broiler has an opening of 22 in. x 12 in.,
the 12 in. width is below the minimum allowable cai-
culated dimension of 14.4 in. (36.6 cm) and therefore
would not be acceptable for overhead protection.
� Salamander Broiler Protection
The R-102 system uses three different nozzle locations for sala-
mander broiler protection. All of the design options require a one-
flow nozzle.
Salamander Broiler Protection - 1 N(1-Flow) Noule Overhead
A salamander broiler with a maximum hazard area (internal broil-
er chamber) of 16 in. (41 cm) deep x 29 in. (74 cm) wide can be
protected using a 1 N nozzle, Part No. 419335. The nozzle tip is
.stamped with 1 N, indicating thai this is a one-flow nozzle.
The single 1 N nozzle must be located directly in line with either
vertical edge of the broiler opening, 6 in. (15 cm) to 12 in. (30 cm)
in front of the broiler, and 0 in. to 12 in. (30 cm) above the top of
the broiler. The nozzle must be aimed at the center of the broiler
. opening. See Figure 57a.
