App1ication
The R-102 system uses four different nozzles for the protection
of griddles. One of the applications requires a 1-flow nozzle and
three of the applications require a 2-flow nozzle.
High Proximity Application: Ji. —to 40iin. (889 to 1016 mm)
above the cooking surface. - - -- -
This high proximity application uses the 1 N nozzle.
The nozzle is stamped with 1 N indicating this is a one-flow
nozzle and must be counted as one flow number.
One 1 N nozzle will protect a maximum cooking area of0801n
(69677 mm2) with the maximum longest side oj361T(914 mm).
When using this nozzle for griddle protection, the nozzle must be
positioned along the cooking surface perimeter to a maximum of
2 in. (50 mm) inside the perimeter, and aimed to the midpoint of
the cooking surface. See Figure 4-39 and 4-40.
NOTICE
When using this type of griddle protection,
only five flow numbers are allowed on a 1.5
gal (5.7 L) system and only 11 flow numbers
are allowed on a 3 gal (11.4 L) system.

Once the hazard analysis is completed and the total nozzle flow
numbers are established, the quantity and size of agent tanks and
cartridges needed to supply the nozzles with the proper volumes
of agent at the proper flow rates can be determined. For cartridges
used in the regulated release mechanism, flow capacities, tank
quantities and sizes, and regulated release cartridge options are
given in the table below.

The 101-30 cartridge can not be used when (2) two 3.0 gallon tanks are nianifolded together.
For higher total flow numbers (23 to 110), multiple cartridges and
regulated actuators are required as shown in the System Selection
Guide in Section IX - Appendix.
ACTUATION AND EXPELLANT GAS LINE REQUIREMENTS
This section contains the guidelines for installing the actuation and
expellant gas lines between the regulated release mechanism reg-
ulator, each regulated actuator regulator, and each agent tank.
These limitations should be considered when selecting the com-
ponent mounting locations.
The actuation gas line is the length of pipe and/or hose that is run
from either the AUTOMAN Regulated Release Assembly or the
Remote Release Assembly that directs high pressure from the
cartridge in the release to actuate one or more additional
Regulated Actuator Assemblies. The actuation gas line can consist
of 1/4 in. Schedule 40 black iron, chrome-plated, stainless steel, or
galvanized steel pipe and fittings, and/or factory supplied stainless
steel braided actuation hose.
The expellant gas line is the length of pipe that is run from the
regulator in either the AUTOMAN Regulated Release Assembly or
a Regulated Actuator Assembly that directs regulated pressure to
the agent storage tanks to pressurize the tank and discharge the
agent. The expellant gas line shall consist of 1/4 in. Schedule 40
black iron, chrome-plated, stainless steel, or galvanized steel pipe
and fittings.
Actuation Gas Line - 6 to 8* Tanks Maximum
* 8 Tank maximum reflects the utilization of 3 tank regulated actuators.
Use only 1/4 in. Schedule 40 black iron, hot-dipped galva-
nized, chrome-plated, or stainless steel pipe and fittings.
The actuation gas line piping is installed from the regulated
release mechanism to each regulated actuator connected
within the system. The total length of the actuation gas line
from the regulated release assembly to the regulated actuator
assembly(ies) must not exceed 20 ft (6 m) when using an
LT-20-R, an LT-30-R nitrogen cartridge, or a 101-10 or a
101-20 carbon dioxide cartridge. See Figure 100.

Expellant Gas Line
1. The expellant gas line is installed from the regulated release
mechanism in double, three, and multiple-tank systems, and
from the regulated actuator assembly in multiple-tank sys-
tems. The expellant gas line is the piping and/or hose between
the regulator and the tank-enclosure/tank-bracket assembly.
The total length of the epellant gas line from the regulated
release mechanism or each regulated actuator assembly
must not exceed 30 ft (9 m) when using a "double-tank" car-
tridge, an LT-A-101-30 Cartridge, or a 101-30 Cartridge. See

4. If three 3.0 gallon tanks are connected to the regulator in
either a regulated release or regulated actuator assembly,
only factory supplied expellant gas hose assemblies will be
utilized. Refer to Distribution Piping Requirements - 9.0
Gallon System, page 4-55 for additional design requirements.
DISTRIBUTION PIPING REQUIREMENTS
Once the nozzle placement and quantity of tanks has been deter-
mined, it is then necessary to determine the piping configurations
between the tank adaptor and each discharge nozzle. This section
contains the guidelines and limitations for designing the distribu-
tion piping so that the liquid agent will discharge from the nozzles
at a proper flow rate. These limitations should also be referred to
when selecting the mounting location for the regulated release
mechanism and agent tank.
General Piping Requirements
All R-1 02 system piping is straight line. Therefore, the need for
critical lengths and balancing is minimized.
Two 45° elbows count as one 90° elbow.
Each branch line includes the tee or elbow leading to it, and
all fittings within the branch line itself.
The minimum piping length of Schedule 40, 3/8 in. pipe from
the tank outlet to any nozzle protecting a range, fryer, or wok
must be 6 ft (1.8 m).
Pipe lengths are measured from center of fitting to center of
fitting. See Figure 105.

FIGURE 105
000778
All distribution piping must be 3/8 in. Schedule 40 black iron,
chrome-plated, or stainless steel. Do not use hot dipped gal-
vanized pipe on the distribution piping.
All threaded connections located in and above the protected
area must be sealed with pipe tape. Tape should be applied to
male threads only. Make certain tape does not extend over the
end of the thread, as this could cause possible blockage of the
agent distribution.
Before installing blow-off caps on nozzles, apply a small
amount of Dow Corning No. 111 silicone grease across the
opening in the nozzle tip and also a small amount coating the
exterior of the blow-off cap. This will help keep cooking grease
from building up on the cap.
Tees used in the distribution piping can be used as thru tees,
side outlet tees, or bull tees.
A combined total of nine fittings may be used in these lines,
eight 90° elbows and one tee. Two 45° elbows equal one 90°
elbow.
If two tanks are connected to the regulated release assembly
in a multiple-tank system arrangement, the total combined
length of the actuation and expellant gas lines must not
exceed 30 ft (9 m) when using a "double-tank" nitrogen car-
tridge, an LT-A-101-30 nitrogen cartridge, or a 101-30 carbon
dioxide cartridge. See Figure 101.

In installations where a UL listed damper assembly is
employed, the duct nozzle can be installed beyond the 8 in.
(20 cm) maximum, to a point just beyond the damper assem-
bly that will not interfere with the damper. Exceeding the maxi-
mum of 8 in. (20 cm) in this way will not void the UL listing of
the system.
Previously listed 3 flow number and 5 flow number duct pro-
tection detailed in earlier published manual, Part No. 418087-
06, can also still by utilized.

Perimeter Perimeter
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
1 nozzle every 10 ft (3.1 m) or less depending on the overall
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 ft (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
within the discharge pattern of either nozzle.

Gas-Radiant/Electric Char-Broiler Protection
The R-1 02 system uses the 1 N nozzle, (Part No. 419335) for gas-
radiant/electric char-broiler protection.
The nozzle tip on the 1 N nozzle is stamped with a 1 N, indicating
that this is a one-flow nozzle and must be counted as one flow
number.
One IN nozzle will protect a hazard with a maximum length of
36 in. (91 cm) and a total cooking area which does not exceed
864 j2 (5574 cm2). The nozzle tip must be located 15 to
40 in. (38 to 102 cm) above the hazard surface. When using this
nozzle for gas-radiant/electric char-broiler protection, the nozzle
must be positioned anywhere along or within the perimeter of the
maximum cooking area and shall be aimed at the center of the
cooking surface. See Figure 59.

Range Protection (With or Without Back Shelf/Obstruction)
When this type of hazard is equipped with a back shelf or other
similarly sized obstruction located above the range top, two pro-
tection options are available: One requires a 1 F nozzle, Part No.
419333, and the other option requires a 260 nozzle, Part No.
419341.
Range Protection 1 F (1-Flow) Nozzle (With or Without Back
I Shelf/Obstruction)
Single and multiple burner ranges can be protected using a 1F
nozzle, Part No. 419333. The nozzle tip is stamped with 1 F indi-
cating that it is a one-flow nozzle and must be counted as one flow
number.
When using the 1 F nozzle for range protection with or without back
msheIf or other similarly sized obstruction, the maximum length of
the burner grates being protected must not exceed 28 in. (71 cm)
and the maximum area of the burner grates must not exceed
336 in.2 (2168 cm2). See Figure 37 for nozzle location details.

Griddle Protection 1 (1-Flow) Nozzle - High Proximity
I Application
The R-102 system uses four different nozzles for the protection of
griddles. One of the applications requires a 1-flow nozzle and
three of the applications require a 2-flow nozzle.
High Proximity Application: 35 in. to 40 in. (89 to 102 cm) above
the cooking surface.
This high proximity application uses the 1 N nozzle, Part No.
419335.
The nozzle tip is stamped with 1 N indicating this is a one-flow noz-
zle and must be counted as one flow number.
One 1 nozzle will protect a maximum cooking area of 1080 in.2
(6968 cm2) with the maximum longest side of 36 in. (91 cm).
When using this nozzle for griddle protection, the nozzle must be
positioned along the cooking surface perimeter to a maximum of
2 in. (5 cm) inside the perimeter, and aimed to the midpoint of the
cooking surface. See Figure 39 and 40.
NOTICE
When using this type of griddle protection, only
5 flow numbers are allowed on a 1.5 gal (5.7 L)
system and only 11 flow numbers are allowed
on a3 gal (11.4 L) system.

P. 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 (1-Flow) Nozzle 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 that this is a one-flow nozzle.
The single iN 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.
