OPERATION AND MAINTENANCE
Top and bottom heating units are each operated by a three heat heavy duty reversible switch.. An oven thermostat with pilot light is also provided.. The thermostat maintains the temperature and the switches determine the source of the heat..
1Turn the top heating unit to HIGH..
2Turn the bottom heating unit to HIGH..
3.Set the oven thermostat to the desired temperature.. The pilot light will now come ON..
4.When the desired temperature is reached, the pilot light will go OFF.. At this time the top heating unit switch may be turned OFF or set as desired..
5The bottom heating unit switch may be left at HIGH or adjusted as desired..
Thermostat Calibration
All electric ovens are equipped with snap action thermostats.. Field calibration is seldom necessary and should not be resorted to unless experience with cooking results definitely provides that the control is not maintaining the temperature to which the dial is set.. To check the oven temperature when calibrating, use only a reliable mercury thermometer or preferably an oven pyrometer..
1.Place the thermocouple of the test instrument or reliable mercury thermometer in the center of the oven..
2.Turn oven temperature control dial to 400°F (204°C).. In order to allow the oven temperature to stabilize, the oven control must be allowed to cycle twice before taking a test reading
3.Check temperature reading control just as it cycles ‘OFF” as indicated by the cycling pilot.. If the temperature doe not read within 15°F (8°C) of the dial setting, recalibrate as follows
4.Carefully remove the thermostat dial, not disturbing the dial setting..
5.Hold the dial shaft steady and with a screwdriver, turn the calibration screw, located inside the dial shaft clockwise to decrease and
6.Replace the thermostat dial and repeat steps 1 through 3 to verify that the correct adjustment has been made..
Cleaning of Core Plates
1.Set the thermostat dial to 550°F (288°C) at the end of the cooking day and allow to cycle for one hour..
2.When the oven has cooled the residue will have carbonized and can be removed by sweeping with a stiff wire brush..
3.Stubborn residue can be loosened with a scraper..
