4. Remove the basket support frame when lling the frypot with solid shortening.
5. When solid shortening is used, be careful not to bend, break, or twist the thin capillary wires of the sensing
elements located in the frypot.
6. Pack solid shortening into the zone below the tubes, all spaces between the tubes, and at least an inch above
the top of the tubes before lighting the fryer. If any air spaces are left around the heat tube surfaces when
the heat is turned on, the tube surfaces will become red hot, burn the solid shortening, weaken the frypot, and
CAUTION
NEVER ATTEMPT TO MELT A SOLID BLOCK OF SHORTENING ON THE TOP OF THE HEAT TUBES.
NEVER START THE BURNERS WHEN THE FRYPOT IS EMPTY.
7. To prevent burning or scorching the solid shortening, keep the thermostat set at the lowest temperature until
all the solid shortening between and above the tubes has been melted. Additional solid shortening can then
be added until the desired frying depth has been reached.
8. Replace the basket support frame over the frypot heat tubes.
SHUTDOWN PROCEDURE
Standby: Turn knob on the combination gas valve to the “PILOT” position. At this setting, only the pilot burner will
remain ignited.
Complete Shutdown: Turn knob on the combination gas valve clockwise, press down on the knob and continue to
turn to the “OFF” position.
RELIGHTING
1. Shut o all gas.
2. Wait ve minutes.
3. Follow the "Lighting" procedure as described on page 10.
WARNING
In the event of a main burner ignition failure, a ve minute purge period must be observed prior to re-
establishing the ignition source.
AUTOMATIC PILOT VALVE
The Automatic Pilot Valve provides an automatic safety shuto for the fryer when the pilot ame is extinguished.
When the pilot ame is burning, the valve is held open electromagnetically by the electrical current from a
thermopile in the pilot ame. When the pilot ame goes out, generation of current ceases and the valve closes
automatically.
HIGH LIMIT CONTROL
Avantco Floor Fryers are equipped with a secondary heat control that prevents the oil temperature from rising
above 450°F. (Because of the accuracy tolerance of the sensor, the oil temperature may reach as high as 475°F.)
In the event the fryer shuts down due to this condition, the oil must be cooled to below 400°F before the pilot
burner can be re-ignited. When the oil has cooled, use the “Lighting” procedure on page 9 to place the fryer back in
operation. If the problem persists, contact your Avantco Service Representative or the Avantco Service Department.
