the use of charcoal, mesquite chips, chunks, and/or logs
that are used for cooking.
Two nozzles are available for natural charcoal char-broiler
protection. High proximity and low proximity. The maximum
depth of fuel (charcoal) must not exceed 6 in. (152 mm).
The 1H nozzle (Part No. 551029) is used for high proximity
natural charcoal 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 35 in. (609.6 mm
to 889 mm) above the cooking surface of the appliance and
aimed at the center of the broiler surface. See Figure 3-23.
The 1L nozzle (Part No. 551026) is used for low proximity
natural charcoal char-broiler protection. This nozzle is a one
flow nozzle. The nozzle must be located
anywhere on the
