1. Turn all burner valves to OFF. Wait 5 minutes to allow gas which may have accumulated in the burner
compartment to escape.
2. Turn gas supply to the griddle ON.
3. Turn on the electric supply to the griddle by turning the toggle switch to ON. The red light will light.
4. At closing time, turn the toggle switch to OFF. The pilot, igniter, red light, and thermostat will be turned off.
Operating a Griddle with the Electric Ignition Option
1. Turn the toggle switch to ON. The red light will light, the igniter will spark (not visible) and ignite the pilot.
2. When the pilot is lit, the igniter will turn off.
3. The griddle may now be operated from constantly burning pilots. Turning the thermostats as desired is all that
is required to put the griddle into service.
For the griddle plate, turn burners on about 15-20 minutes before cooking for preheating. Set the thermostat dials
to the desired griddle plate temperatures. Each thermostat will control gas flow to burners to bring that area of
the plate up to the set temperature.
4. If the pilot goes out, the electric ignition will automatically relight the pilot.
5. If the electricity to the griddle goes off, the gas supply to the pilots and to the burners is automatically shut off.
Extended Shutdown
To turn the griddle completely off for an extended shutdown:
1. Turn electric supply to the griddle OFF.
2. Turn gas supply to the griddle OFF.
If griddle is to be shut down for an extended period, put a heavy coat of grease over the griddle plate to inhibit rusting.
LIGHTING THE STANDING PILOT ON THE OPEN BURNERS TO THE LEFT OR RIGHT OF THE GRIDDLE, OR
AS FREE-STANDING HOTPLATES
1. Turn all burner valves to OFF. Wait 5 minutes to allow gas which may have accumulated in the burner
compartment to escape.
2. Turn main gas supply to the griddle ON.
3. Light the pilot and adjust the pilot regulating valve (Fig. 3) to give a stable pilot flame.
4. If the pilot light goes out, turn the burner controls to the OFF position. To relight, repeat Steps 1, 2, and 3.
ADJUSTMENTS
Main burner air supply: For efficient burner operation, it is important that a proper balance of gas volume and primary
air supply is maintained to give complete combustion. Insufficient air supply results in a yellow streaming flame.
Primary air supply is controlled by the air shutter on the front of the burner venturi. Loosen the screws on the venturi
and adjust the air shutter to just eliminate yellow tips on burner flames. Lock the air shutter in place by tightening the
screws. Repeat this procedure with all burners.
The burners and pilot flames may be observed through round holes in the upper front panel.
