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".
Lighting main burner
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 small flame, there is a preset low).
Main burner air supply:
1. 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.
2. 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.

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 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, 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
Season Griddle:
Heat to low temperature (300 - 350 F/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.
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 plate 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 griddle will produce the most consistent product results.
