CLEANING AND MAINTENANCE

Thermostat Calibration

For Millivolt Thermostats refer to the following procedure.

a.Remove the tube rack from the tank and place the tip of a digital thermometer in the shortening/oil approximately one inch above the temperature sensor.

Light the pilot as described in this manual, set the thermostat to 325°F (163 °C) and allow the shortening/oil to come up to temperature; let the appliance cycle 4-6 times to insure that the shortening/oil temperature has stabilized. Compare the thermostat setting of 325°F (163 °C) to the digital thermometer reading.

b.Remove the thermostat dial by pulling the knob straight out. DO NOT rotate the dial.

c.Holding the outside of the shaft so that it does not move, scrape away the sealing compound in the center of the shaft with a small flat blade screwdriver.

d.Turn the adjustment screw clockwise to lower the thermostat’s temperature setting or counter- clockwise to raise it.

NOTE

One-quarter turn of the adjustment screw changes the temperature setting

approximately 24°F (13 °C).

e.Turn the adjustment screw until the burners come on at 325°F (163 °F).

f.Replace the knob and allow the appliance to cycle 4 to 6 times. Check the temperature of the digital thermometer against the thermostat dial setting; if there is greater than a 5°F

(3 °C) difference, repeat the calibration procedure.

Weekly Cleaning

General Cleaning

The appliance should be thoroughly cleaned AT LEAST once a week. This should include a thorough wipe down of the entire appliance with a rag and mild detergent.

WARNING

The power supply must be disconnected before cleaning and servicing this appliance!

WARNING

NEVER spray cleaner into the main burners or pilot. This could act as a magnet for dust and other debris, causing it to accumulate and inhibit the proper operation of your appliance.

Boil Out Procedure

The appliance should be boiled out AT LEAST once a week to remove food debris and shortening/oil build up. You will need a container large enough to hold 1 ½ times the shortening/oil in the tank. Refer to the following procedure for weekly boil out.

WARNING

Completely shut the appliance down when the shortening/oil is being drained and replaced with water. This will prevent the main burners from coming on during the draining and filling procedure.
