LIGHTING INSTRUCTIONS
OPERATING INSTRUCTIONS
GF-30H and HLP Fryers are furnished with a pilot safety valve. Please follow the instructions below.
Fill the fat tank about 3/4" below the full line with proper frying cornpound before lighting pilot. The reason for
filling the tank 3/4" below the full line is that the frying corn pound will expand during the preheating process.
If the frying compound expands above the full line, the frying compound may overflow out of the tank during
the cooking process. The reason for adding fry compound in fry tank before lighting the pilot or burners is
that the unit will be damaged if this is not done.
1. Turn on main gas supply to unit, on-off valve located under the unit.
2. Turn the burner temperature control knob to "OFF" position. Open the front panel and wait at least 5
minutes to allow any gas which may have accumulated in the combustion chamber to escape.
3. Turn the Off/Pilot/On valve control to Pilot. Depress the Off/Pilot/On valve control on the valve and
light the pilot. Keep the Off/Pilot/On valve control depressed for at least 1-2 minutes after pilot has lit.
I f pilot does not stay lit, repeat this step.All valve controls and dials must be operated by hand. Never
use pliers, wrenches or other tools to rotate valve control and temperature dial.
4. If pilot flame needs to be adjusted, remove the pilot adjust cover screw and turn the inner adjustment
screw clockwise or counter-clockwise to adjust pilot flame to 1/2" to 3/4" long (12/19 mm) above the
pilot channel. This can be done while pilot stays lit to see flame size.
1. Make sure the temperature dial is in the off position before turning the Off/Pilot/On valve control to
the on position.
2. Wait at least 5 minutes for the Pilot/thermopile to warm up before turning the Off/Pilot/On valve to
the on position.
3. Since the burners are lit from constantly burning pilot, turn the temperature control knob to 375
degrees to put the unit in operation; then adjust to any desired temperature.
4. If the burners do not ignite, turn temperature dial to the off position and let the thermopile warm up
for a few more minutes then turn the temperature dial to 375 degrees to put in operation.
5. If the burners still do not ignite within 5 seconds, turn temperature dial to the off position. The pilot
flame may be too short and adjust to specification in step 4 above. Then repeat burner ignition
steps.
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. There
may be no obstructions to the bottom of the unit or the top flue. Primary air supply is controlled by an air
shutter on the front-of each burner. Loosen the hexagonal head screw on front of the burner, and adjust the
air shutter to just eliminate yellow tips of burner flame. Lock the air shutter in place by tightening the screw.
Repeat this procedure with all burners if necessary.Adjustment may not be required.
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.
