CHAPTER 8: TROUBLESHOOTING

8.1Pilot Burner Malfunction (cont.)

C.Pilot flame of proper size, but is unstable. Flame wavers and does not envelope the thermocouple completely at all times.

ƒCheck for drafts that might be caused by air conditioning equipment or make-up air apparatus. Turn air-moving equipment off and recheck the pilot.

8.2Main Burner Malfunctions

A.Main burner will not come "ON"; gas not detected at main burner.

1.Check that the gas valve is open.

2.Check that the pilot is ignited and is operating properly.

3.Authorized Service Agent Only: Check the high-limit switch for continuity.

4.Authorized Service Agent Only: Check the combination gas valve and replace if defective.

B.Main burner flames are small and appear lazy; shortening does not come up to temperature quickly.

• Authorized Service Agent Only: Check gas pressure at the pressure tap of the gas valve. Use dial type or standard water-type U-gauge manometer. With burner in operation, the pressure should be 4" W.C. for D and HD models utilizing natural gas. The pressure should be 11" W.C. for D models and 10" W.C. for HD models utilizing propane. If not, remove the pressure regulator adjustment cover. Use screwdriver to turn the adjusting screw for proper pressure. Replace cover, re-check pressure and re-install pressure tap plug.

C.Signs of excessive temperature; shortening scorches and quickly becomes discolored.

1.Check operating thermostat. May be out of adjustment or calibration. Recalibrate if necessary.

2.Check gas pressure as outlined above.

3.Shortening used is of inferior quality and/or shortening has been used too long. Replace shortening.

4.Ensure frypot is clean when refilling with new shortening.
