CHAPTER 8: TROUBLESHOOTING

8-2

8.2 Pilot Burner Malfunction (cont.)

4. Check all connections for cleanliness and security.

C. Pilot flame of proper size, but is unstable. Flame wavers and does not envelop the

thermocouple completely at all times.

1. Check for drafts that might be caused by air conditioning equipment or make-up air

apparatus. Turn air-moving equipment off and recheck the pilot.

8.3 Main 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. Check the high limit switch for continuity.

4. The combination gas valve may be defective; replace if necessary.

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

quickly.

1. 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. (10

mbar) for natural gas, and 11" W.C. (27.5 mbar) for propane.

2. 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 gas pressure as outlined above.

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

shortening.

3. Ensure vessel is clean when refilling with new shortening.
