LIGHTING INSTRUCTIONS
HCB and HCRB 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 Operation Flame Failure Gas Valve:
Operation of the gas valve pilot:
1. Turn knob on the main gas valve to the pilot position
2. Depress knob to start gas flow to the pilot valve
3. Light pilot valve
a. Using a match or taper
4. Hold in knob for 15 to 30 seconds to heat up the thermocouple
5. Release knob and turn to the desired gas flow position
a. If pilot goes out repeat steps 1-4, some thermocouples will take longer to heat up
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. The valve can be accessed through an opening in the front panel or remove the cooking grates
and light the pilot from above.
4. Turn the manual shut off valve on.
5. Hold an ignition source (match) to both openings on the pilot tube. When the flames are
established, remove the ignition source.
6. 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:
lPromptly shut off all gas at the manual shut off valve.
lTurn off all knobs and pilot valves; wait 5 minutes to clear gas.
lRelight 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".
lTo 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).
lWhen 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.
lTurn knobs off and let cool .
lFor 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.
lClean regularly. Grates may be removed for washing in the sink. Brush out carbonized particles.
Thoroughly wash the grease/water pan.
CAUTION
Never attempt to move a grill section while cooking. An unexpected flare could cause severe injury. Turn off
the unit, let it cool and use potholders and/or gloves to reposition or remove. The space between the legs at
the bottom admits combustion air. DO NOT BLOCK THIS SPACE.

10
Main burner air supply:
For efficient burner operation, a proper balance of gas volume and primary air supply must be maintained
which will result in complete combustion. Insufficient air supply results in a yellow streaming flame. Primary
air supply is controlled by an air shutter on the front of the burner.
Loosen the screws on the front of the burner, and adjust the air shutter to just eliminate the yellow tips of the
burner flame. Lock the air shutter in place by tightening the screws.
European Community:
If adjustment becomes necessary in the field, it should be done by a factory authorized and trained
technician who should seal the screw after the adjustment to safeguard against unauthorized
tampering by the end user.
All burners are lit from constantly burning pilots. Turning the valve to the desired flame height is all that is
required to put the unit in service.
Do not permit fans to blow directly at the unit. Wherever possible, avoid open windows next to the units'
sides or back. Avoid wall type fans which create air cross-currents within a room.
It is also necessary that sufficient air should be allowed to enter the room to compensate for the amount of air
removed by any ventilating system. Otherwise, a subnormal atmospheric pressure will occur, which will
effect operation and cause undesirable working conditions.
A properly designed and installed hood will act as the heart of the ventilating system for the room or area in
which the unit is installed and will leave the unit independent of changing draft conditions.
All valves must be checked and lubricated periodically. This must be done by an authorized service
representative in your area.
OPERATING INSTRUCTIONS
OPERATION: Turn the burners on about 15-20 minutes before cooking for preheating. Set the knobs to the
desired flame height or temperature. Each valve will control the gas flow to the burner to bring that area of
the unit up to the set temperature. If different temperature settings are to be used, adjoining areas should be
set at progressively higher temperatures using the lowest temperatures on the outside burners. A uniform
and systematic approach to the loading of the unit will produce the most consistent product results.
RADIANTS
Place the radiants in their position as shown in Sketch 1. Make sure that the radiants are setting properly
into the slots on the front and rear supports. Radiants should be centered over straight section of the
burners.
COOKING GRATES
Place the top cooking grates with the grid bars sloping toward the front as shown in Sketch 2.
SEASON GRIDDLE
Heat to low temperature (300 - 350F/150-180C) and pour on a small amount of cooking oil, about one
ounce (30cc) per square foot of surface. Spread the oil over the entire griddle surface with a cloth to create
a thin film. Wipe off any excess oil with a cloth. Repeat this procedure 2 to 3 times until the griddle has a
slick, mirror-like surface.
NOTE: When cooking grates are placed sloping toward the front, the grooves on top will guide the excess
fat drippings into the grease trough. For wider branding marks turn the cooking grate over so the product is
placed on the wider rails. There is less grease removal with the cooking grates in this position so there will be
a little more flare ups in this position.
CAUTION: Do not turn on gas valves without lighting pilots. This could cause a build up of
gas and potential explosion.
