Checking and adjusting pressure regulator
1. Turn thermostat “OFF” and combination gas valve knob to the “PILOT” setting.
2. Remove pressure tap plug from burner manifold located directly below the burners in the cabinet.
3. Install a fitting appropriate to connect a manometer.
4. Turn combination gas valve to “ON” position and thermostat to “ON.” The burners will ignite. Be
certain that sufficient oil is covering the tubes.
5. With burners on, read manometer.
6. If the manometer does not read 4" W.C. for natural gas, or 10" W.C. for propane gas, adjust regulator.
7. Remove regulator adjustment screw cap (see diagram on page 18).
8. With small screwdriver rotate adjustment screw “CLOCKWISE” to increase or “COUNTERCLOCKWISE”
to decrease pressure. Be sure to adjust with burners “ON.”
9. Turn thermostat “OFF” and set combination gas valve knob to “PILOT” position.
10. Remove manometer and replace pressure tap plug.
11. Replace adjustment screw cap.
Checking and adjusting calibration of thermostat
1. To check appliance temperatures, use a thermocouple-type temperature test instrument or reliable
thermometer. Place the thermocouple of test instrument or thermometer in the center of the fry pot.
2. Turn the control dial to the temperature setting requiring the greatest accuracy. Allow enough time
for temperature to stabilize, or until several temperature readings are identical.
3. Recalibrate if setting and actual temperature
differ by more than 10°F.
4. Remove dial from dial shaft “B.” Be careful that
dial shaft does not rotate in either direction
(which would change the dial setting).
5. Hold dial shaft “B” steady and with a
screwdriver turn calibration screw “A”
clockwise to decrease the temperature, or
counterclockwise to increase the temperature.
6. Replace dial. Let the appliance operate until
the temperature has stabilized before a final
check is made to determine whether or not the
calibration has been corrected.
7. Once correct, seal the calibration screw with
glyptol.
The combination gas valve (includes pressure regulator) is factory set at 4" W.C. for natural gas and 10" W.C.
for liquid propane gas. To check the manifold pressure, do the following:
All thermostat controls are carefully calibrated at the factory (i.e., the dial is properly set to control appliance
temperatures accurately). Only a qualified appliance service technician should perform this adjustment.
