TROUBLESHOOTING FOR AUTHORIZED SERVICE TECHNICIANS ONLY!

NOTICE
Warranty will be void and the manufacturer is relieved of all liability if:

• Service work is performed by other than a qualified technician (see warranty doc for details) OR
• Other than approved Avantco replacement parts are installed.

WARNING: Adjustments and service work may be performed only by a qualified technician who is experience in, and knowledgeable with, the operation of commercial gas cooking equipment. However, to ensure your confidence, contact your Avantco Service Representative for liable service, dependable advice or other assistance, and for genuine factory parts.

All units are adjusted at the factory. In case of problems in operation at initial installation, check type of gas and manifold pressure and compare with information listed on the serial plate. A mill voltage circuit diagram is located inside the front door of the fryer, and also on page 19.

CHECKING AND ADJUSTING MAIN BURNERS

The main burners should burn with a steady blue flame, and the inner cone of the flame from each port should be about 3/4″ long. The flame from each main burner should enter each heat tube without touching the front of the fry pot or the sides, top, or bottom of each tube.

• Yellow Tips (too little air or too much gas)
• Blowing or Lifting Tips (too much air)
• Normal Flame

Checking and adjusting pressure regulator

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:

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

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.

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.

Checking and Adjusting Safety Pilot

The pilot flame should surround the thermopile for 1/2″. It must be large and sharp enough to cause the thermopile to glow a dull red, or sufficient to hold the safety valve open.

1. Remove pilot adjustment cap.
   

2. Adjust pilot key to provide properly sized Diagram A shows improperly adjusted pilot.

3. Release pilot adjustment cap.
