HIGH EFFICIENCY DECATHLON SERIES GAS FRYERS

CHAPTER 1: SERVICE PROCEDURES

1.5 Adjusting the Pilot Flame

1.5.1 Main Pilot

1.Remove the cap from the pilot adjustment screw hole on the gas valve.

2.Using a small, flat-tipped screwdriver, turn the pilot adjusting screw counterclockwise to increase length of flame or clockwise to decrease length of flame. Adjust to obtain a flame from 1 inch to 1½ inches long.

3.Reinstall the pilot adjustment screw cap.

1.5.2 Trailing Pilot

Unlike older Decathlon units, current production HD units do not have a trailing pilot adjustment.

1.6 Calibrating the Thermatron

1.Fill the frypot to the lower OIL-LEVELline with cooking oil. If solid shortening is used, it must be melted before starting the calibration procedure.

2.Ensure the fryer ON/OFF switch is in the OFF position and light the pilot.

3.Place the fryer ON/OFF switch in the ON position. Set the potentiometer dial to 325°F (162°C).

4.Allow the oil to equalize at setpoint temperature. This is evident when the burners have cycled on and off several times.

5.Insert a thermometer or pyrometer into the frypot within 3 inches of the probe bulb. Ensure the tip of the thermometer/pyrometer does not touch the frypot burner tube.

6.If the temperature on the thermometer is higher or lower than 325°F (162°C), the knob is out of calibration.

7.Calibrate the knob by first loosening the setscrew and slowly turning the knob to match the temperature reading of the thermometer. Tighten the setscrew, ensuring the knob does not move on the shaft during tightening.

8.Allow burners to cycle on and off several times, then recheck oil temperature as described in Step 5. If the thermostat dial temperature matches the thermometer temperature, the thermostat is calibrated. If not, repeat Step 7.
