Salamander Broiler Protection – 1N (1-Flow) Nozzle
Overhead
A salamander broiler with a maximum hazard area (internal
broiler chamber) of 16 in. (406 mm) deep x 29 in. (736 mm) wide
can be protected using a 1N nozzle. The nozzle is stamped with
1N, indicating that this is a one-ow nozzle.
The single 1N nozzle must be located directly in line with either
vertical edge of the broiler opening, 6 in. (152 mm) to 12 in. (304
mm) in front of the broiler, and 0 in. to 12 in. (304 mm) above the
top of the broiler. The nozzle must be aimed at the center of the
broiler opening. See Figure 4-57a.

A salamander broiler with a maximum hazard area (internal
broiler chamber) of 15.5 in. (393 mm) deep x 31 in. (787 mm)
wide can be protected using a 1F nozzle. The nozzle is stamped
with 1F, indicating that this is a one-ow nozzle.
The single 1F nozzle must be located directly in line with the
center of the broiler opening, 8 in. (203 mm) to 12 in. (304 mm)
in front of the broiler and 12 in. (304 mm) to 18 in. (457 mm)
above the top of the broiler. The nozzle must be aimed at the
center of the top broiler opening when the grate is located in the
middle position. The nozzle must be orientated so the nozzle
tip ats are parallel with the grate left to right centerline. See

ered when protecting a salamander broiler/range combination
appliance that employs casters.
A salamander broiler with a maximum hazard area (internal
broiler chamber) of 15 in. (381 mm) deep x 31 in. (787 mm) wide
can be protected using a 1N nozzle. The nozzle is stamped with
1N, indicating that this is a one-ow nozzle.

Upright Broiler/Salamander Protection
The R-102 system uses two 1/2N Nozzles for all upright broiler
protection. The nozzle is stamped 1/2N, indicating that this is
a half-ow nozzle. A pair of these nozzles will equal one ow
number.
Two 1/2N nozzles will protect a maximum hazard area (internal
broiler chamber) of 30 in. x 32.5 in. (761 mm x 825 mm). These
nozzles must always be used in pairs on an upright broiler. One
nozzle must be positioned above the grate and pointed at the
back opposite corner of the broiler chamber. The second nozzle
must be pointed down into the center of the drip pan through the
open slot. See Figure 4-58.
