6.2  Pilot Burner Malfunction (cont.) 

 

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. 

 

 

 CAUTION 

Do not attempt to turn the adjustment past the stops or the controller will be 

damaged. 

 
 

6.3  Main Burner Malfunction 

 

A.

 

Main burner will not come "ON"; no gas 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 3.5" WC 
(8.75 mbar) for natural gas, and 10" WC (25 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 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 vessel is clean when refilling with new shortening.
