Operation
High Limit Control
Thor Fryers are equipped with a secondary heat control that prevents the oil temperature from rising above
195
°
C/450
°
F. (Because of the accuracy tolerance of the sensor, the oil temperature may reach as high as
200
°
C/475
°
F.)
In the event the fryer shuts down due to this condition, the oil must be cooled to below 185
°
C/400
°
F before
the pilot burner can be re-ignited. When the oil has cooled, use the “Lighting” procedure on page 11 to place the
fryer back in operation. If the problem persists, contact your Thor Service Representative or the Technical Service
Department of the manufacturer.
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.
CAUTION
The space between the legs at the bottom admits combustion air. DO NOT BLOCK THIS SPACE.
All burners are lit from constantly burning pilots. Turning the valve to the desired flame height 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 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.
Note:
Please wait at least 15 seconds to restart the main burners to maintain the best function of the thermostat valve
after turning off the main burners.
IMPORTANT
Should any abnormal operation like;
- ignition problems,
- abnormal burner flame,
- burner control problems,
- partial or full loss of burner flame in normal operation, be noticed, the appliance requires IMMEDIATE
service by a qualified service person and should not be used until such service is carried out.
