(624 in.2 (40257 mm2) x 26
in. (660 mm) longest side maximum)
Note:
Radiant charbroilers are distinguished by the use of
heated metal strips (radiants) that are used for cooking.
Two nozzles are available for radiant char-broiler protection.
High proximity and low proximity.
The 1H nozzle (Part No. 551029) is used for high proximity
radiant char-broiler protection. This nozzle is a one flow
nozzle. The nozzle must be located
anywhere within the
perimeter
of the hazard area, 24 in. to 48 in. (609.6 mm to
1219 mm) above the cooking surface of the appliance and
aimed at the center of the broiler surface. See Figure 3-19.
The 1L nozzle (Part No. 551026) is used for low proximity
radiant char-broiler protection. This nozzle is a one flow
nozzle. The nozzle must be located
anywhere on the
perimeter
of the hazard surface, 13 in. to 24 in. (331 to
609.6 mm) above the cooking surface of the appliance and
