Thermostat Calibration

To calibrate the Fenwal Thermostat, fill the frypot to the FULL mark with frying compound and turn the burner on. Insert a thermometer in the center of the frypot with the bulb about two inches below the surface. Allow the burner to cycle about four times, the thermometer reading should be within 5° of the thermostat knob setting. If this does not agree with the pointer of the thermostat knob.

1.Loosen the two set screws on the thermostat knob.

2.Set the pointer at the temperature indicated on the thermometer.

3.Tighten the set screws firmly.

4.Be sure the black surface of the knob is spaced away from the dial plate at least the thickness of a dime.

NOTE: DO NOT TURN ADJUSTING SHAFT MORE THAN TWO TURNS IN EITHER DIRECTION OR PERMANENT DAMAGE CAN RESULT. THIS ACTION MAY VOID THE STANDARD WARRANTY.

The Fenwal Thermostat is an electric switch with contacts that open on a temperature rise. It will respond to temperature changes of approximately 1° when the fryer is idling with no food being fried.

Turning the adjusting shaft counter-clockwise increases the temperature at which time the contacts will open. Some of the most common problems occur in connection with the pilot generator. These usually show as poor ignition of the main burner or frequent pilot outage.

Below is a diagram of how the Fenwal thermostat and Hi- Limit controls are wired to the safety system.
