NOTICE

When this appliance is installed with casters, it must be installed with the casters supplied, a
connector complying with either ANSI Z21.69 or CAN/CGA-6.16 and a quick-disconnect device
complying with either ANSI Z21.41 or CAN1-6.9. It must also be installed with restraining

For your protection, we recommend a qualied installing agency install this appliance.

They should be familiar with gas installations and your local gas requirements. In any

case, your gas company should be called to approve the nal installation.

This appliance, its pressure regulator and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of that system at test
pressures in excess of 1/2 PSIG. This appliance and its pressure regulator must be isolated
from the gas supply piping system by closing its individual manual shutoff valve during any
pressure testing of the gas supply piping system at test pressures equal to or less than 1/2
PSIG.

EXHAUST CANOPY

Open hearth broilers inherently create a good deal of heat and smoke and should be

installed under an efcient exhaust hood with ame proof lters. A vertical distance of not
less than 48" shall be provided between the top of the appliance and lters or any other

GENERAL INSTALLATION DATA (continued)

PLACING RADIANTS - RCB SERIES

After the unit is unpacked and installed, place 1 radiant above each burner. Install each
radiant on 2 slots of the rear wall and on 1 pin of the front wall of the liner weld assembly.
Refer to the exploded view in this manual for orientation of the radiants.

PLACING LAVA ROCKS- CB SERIES

Open the lava rock bags and place rock evenly on the lower internal grates - not the top
cooking grates. Spread the lava rock evenly on the grates approximately 1 layer thick.
Do not cover the grates with more than two layers of lava rock. Do not put more than 5
pounds of rock per burner section.

GAS PIPING

Gas piping shall be of such size and so installed as to provide a supply of gas sufcient to

meet the full gas input of the appliance. If the appliance is to be connected to existing piping,
it shall be checked to determine if it has adequate capacity. Joint compound shall be used
sparingly and only on the male threads of the pipe joints. Such compounds shall be resistant
to the action of L.P. gases. WARNING: Any loose dirt or metal particles which are allowed
to enter the gas lines on this appliance will damage the valve and affect its operation. When

installing this appliance, all pipe and ttings must be free from all internal loose dirt.

GAS PRESSURE REGULATOR

A convertible pressure regulator is provided with each charbroiler. It should be connected
to the inlet pipe at the rear of the unit. The gas supply is then connected to it. The supply
pressure to the regulator is not to exceed 1/2 PSIG. It is shipped set for 5" water column
manifold pressure for use with natural gas.

MANUAL SHUT OFF VALVE

A manual shut off valve should be installed upstream from the manifold and within six feet of
the charbroiler.

CONNECTING GAS SUPPLY LINE

The gas inlet of the charbroiler is sealed at the factory to prevent entry of dirt. Do not remove
this seal until the actual connection is made to the gas supply line.

PROPANE GAS - CONVERSION

This charbroiler is equipped with xed orice hoods and is shipped from the factory for use
with natural gas. To convert to propane gas, install the burner orice hoods, located in the

water pan, as follows:

1. Remove grates, radiants and burners.

2. Remove the burner orice hoods and install the orice hoods supplied.

3. Replace the burners, radiants, and grates.

4. Set manifold pressure to (10) inch water column. A 1/8" pipe plug on the burner manifold can
be removed for attaching a pressure gauge. Remove the slotted, or hex-threaded plug from
the pressure regulator. Invert the plug and re-install. The letters "LP" should now be visible
on the plug. The regulator is now set for 10" (25.4 cm) water column. Attach the conversion
label, supplied with the unit, close to the nameplate.

CHECKING FOR GAS LEAKS

Check entire piping system for leaks. Soap and water solution or other material acceptable for
the purpose, shall be used in locating gas leakage.

CAUTION

Matches, candle ame or other sources of ignition shall not be used for locating

gas leaks.
