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 inside the front panel. To open front panel:
•Remove thumb screws from front panel, lift the front panel off of the unit.
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.
•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 maybe required for the first lighting to adjust the
flame for your elevation.
1Turn off the manual shut off valve and wait 5 minutes to clear the gas.
2Turn all knobs to the “OFF” position.
3Remove the grease drawer and front panel for easy access.
4Turn the manual shut off valve on.
5Hold an ignition source (match) at the pilot tube. When the flame is established, remove the ignition source.
NOTE: Standing pilot lighter arms must be lit in two (2) locations. At the end of the tube and in the bend.
6Turn 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”.
7Replace the front panel and grease drawer.
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 5 minutes to clear gas.
•Relight following steps 3 through 8 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.
•When the broiler is first heated, it will smoke until oil used in manufacturing, preservation and dust from storage and ship-
ping 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 meat item.
•Keep the grease/water pan with sufficient water to cover the entire bottom.
•Clean 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 combus-
tion air. DO NOT BLOCK THIS SPACE.
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 un-authorized tampering by the end user.
All burners are lit from constantly burning pilots. Turning the thermostat to the desired temperature 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, affecting operation and causing unde-
sirable 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 and thermostats must be checked and lubricated periodically. Consult the 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 tempera-
ture. If different temperature settings are to be used, adjoining areas should be set at progressively higher temperatures us-
ing the lowest temperatures on the outside burners. A uniform and systematic approach to the loading of the unit will pro-
duce 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 on the front and
rear supports (between the positioning tabs). 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.
Note: When cooking grates are placed sloping toward the front, the grooves on top will guide the excess fat drippings into
the grease trough.

Cleaning / Maintenance:
Initial Cleaning:
Prior to operating your new broiler, thoroughly wash the exterior with a mild detergent or soap solution. do not use abra-
sive cleaners, since this might damage the cabinet finish. If the stainless steel surfaces become discolored, scrub by
rubbing only in the direction of the finished grain.
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.
Cleaning:
DAILY
Remove the grease pan, empty and wash it.
Grate "burn off". The grease buildup on the grates should be cleaned daily (more often as needed).
a. Caution, When handling grates or radiants, always use insulated gloves to prevent burns.
b. Warning, Do not cover the top of the grid grates during a burn off operation. Restricting the airflow by covering the grid
grates may cause them to warp.
c. Place grates on broiler, with grid bars horizontal, facing down.
d. Turn control knobs to "HI" for approximately 45 minutes.
e. Turn off the broiler and allow it to cool for 20 Minutes.
f. Clean top and bottom surfaces of grate with a wire brush to remove animal fats and carbonized grease.
g. Clean channels on grates with a scraper.
h. Remove grates from broiler. Clean top surface of radiants with the wire brush. They may be cleaned in place.
WEEKLY
Thoroughly clean the exposed surfaces of broiler, sides, front and top grease trough, with a damp cloth, then polish with a
soft, dry cloth. A detergent may be used for cleaning. To remove discoloration, use a non-abrasive cleaner.
After performing daily cleaning procedures, proceed with the following:
a. Remove the radiants. Clean reflecting drip shield of any dust or debris with a brush.
Note: Top grid grates and radiants are heavy. They may break if dropped or bumped.
b. Burner air shutter openings must be kept clean.
c. Burner ports must be kept clean. To clean burners, boil them in a strong solution of lye water for fifteen to twenty min-
utes. Then, either brush with a wire brush or clean gas ports with a sharp-pointed metal instrument to insure open
ports.
Extended Shutdown:
Turn the manual shutoff valve to “OFF”; (field installed valve not supplied by the manufacturer), turn all control knobs to
the “OFF” position and shut off the pilot flame by turning the adjustment on the pilot valve.
