GENERAL INSTALLATION INSTRUCTIONS
Ensure gas supply and gas type, as shown on unit nameplate, agree.
Unit installation must conform with the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the National Gas
Installation Code, CSA-B149.1, or the Propane Installation Code, CSA-B149.2 as applicable and in accordance
with local codes.
Screw legs into the permanently fastened nuts on the four corners of the unit and tighten by hand. Level the unit
by turning the adjustment screw at the bottom of each leg. Do not slide unit with legs mounted, lift if necessary
to move unit.
Pipe threading compound must be resistant to the action of liquefied petroleum gases.
Caution: DO NOT use an open flame to check for leaks. Check all gas piping for leaks with a soap and water
solution before operating unit.
THESE UNITS ARE SUITABLE FOR INSTALLATION ON NON-COMBUSTIBLE SURFACES ONLY.
Noncombustible clearances:
0" sides (0 mm) 0" rear (0 mm) 4" floor (102mm)
Do not obstruct the flow of combustion and ventilation air, under the unit by the legs or behind the unit by the
flue.
Adequate clearance for air openings into the combustion chamber is required. Do not place objects between the
bottom of the unit and the counter top.
There must be adequate clearance for removal of the front panel. All major parts except the burners are
removable thru the front if the gas line is disconnected.
Unit must have adequate clearances for servicing. (Sides = 0", Rear = 0", Floor = 4").

DIMENSIONS: GCB-18i & GCRB-18i
CONVERSION
Instructions are for conversion from Natural Gas to Propane (L.P.) on all models GCRB and GCB.
The conversion should be done before connecting the unit to the gas supply.
Units are shipped from the factory equipped for use on natural gas. Orifices necessary for LP (propane) are
provided in a bag tied to the valve on the front panel.
1. Remove the knobs and front panel.
2. Remove the orifice fittings from the valve. Change the orifices to the size recommended for propane (L.P.).
3. Replace the orifice fittings into the valve.
4. Remove cap, invert the insert and replace cap. NOTE: Marking on insert.
5. Continue with the installation.
LIGHTING INSTRUCTIONS
GCB and GCRB Broilers are furnished with either a pilot safety valve or a standing pilot (not available in the
European Community). Please follow the instructions for your unit.
Pilot Safety Valve Lighting Instructions
Lighting instructions are on the right side panel.
5
If the pilot goes out, an automatic shutoff valve turns off the gas supply to the burners. To relight the pilot, follow
this procedure:
Turn the control valve to "OFF". Wait a sufficient length of time to allow gas, which may have accumulated in
the burner compartment, to escape (at least five minutes).
Turn on the main shutoff valve.
Depress and hold in the red button "A" on the automatic shutoff valve while lighting the pilot burner.
When gas at pilot has been burning for about 45 seconds, release the red button. If pilot does not remain lit,
repeat the operation, allowing more time before releasing red reset button. The button can be accessed
through an opening in the front panel.
To adjust the pilot flame, Rotate the knob clockwise to reduce the gas flow, and counterclockwise to
increase the gas flow; to provide a properly sized pilot flame (approximately 1/2" to 3/4" long). (12 to 19 mm)
All units are equipped with fixed orifices for use with natural gas, and no adjustment is necessary.
Units for operation on natural or propane gas, are also equipped with a factory preset pressure regulator
with an outlet pressure of 6.0" W.C. (15 'mbar') for natural gas supply, and 10" W.C. (25 'mbar') for propane
gas supply, and should not require further adjustment.
Standing Pilot Lighting Instructions (Not Available in the European Community)
The pilot lights on the broilers have been set at the factory. A screwdriver may be required for the first lighting to
adjust the flame for your elevation.
1. Turn off the manual shut off valve and wait 5 minutes to clear the gas.
2. Turn all knobs to the "OFF" position.
3. Turn the manual shut off valve on.
4. Hold an ignition source (match) at the pilot. When the flame is established, remove the ignition source.
5. Turn the burner knobs to "HI". If the burner does not ignite, promptly open the pilot valve more. If the pilot
flame appears larger than necessary, turn it down and reset burner ignition. The pilot flame should be as
small as possible but large enough to guarantee reliable ignition of the burners when the knobs are turned to
"HI".
RELIGHTING PILOT
If the pilot light should go out for any reason:
Promptly shut off all gas at the manual shut off valve.
Turn off all knobs and pilot valves; wait 5minutes to clear gas.
Relight following steps 4 through 6 under Standing Pilot Lighting Instructions.
LIGHTING MAIN BURNER:
Since the burner is lit from constantly burning pilot, turn knobs to "HI" to put the unit in operation; then adjust to
any desired position between "LO" and "HI".
To light burner, turn knob to "max". Then back off to the desired flame level. The range of adjustment is
virtually infinite between high and off. (At the small flame, there is a pre-set low).
When the broiler is first heated, it will smoke until oil used in manufacturing, preservation and dust from
storage and shipping are burned off. An hour at "max". On all burners is usually sufficient.
Turn knobs off and let cool.
For first cooking, set the grates at maximum tilt position and preheat before broiling. You will have to
experiment with knob settings and grate position for each particular item.
Keep the grease/water pan with sufficient water to cover the entire bottom.
