Burner Maintenance

Note: The Burner Maintenance section replaces pages 31-33 in the Defender Atmospheric service manual, p/n 238-44943-00.

Burner Inspection

At periodic intervals (every 6 months), a visual inspection should be made of the pilot and main burner for proper operation and to assure no debris is accumulating. The pilot flame should be stable. Some causes for an unstable pilot flame are:

a)Gas pressure is out of specification.

b)Pilot flame not fully engulfing spark/flame sensor.

The main burner should light smoothly from the pilot and burn with a blue flame with a minimum of yellow tips.

Steel burner models self adjust air to gas ratio mixture and do not have an adjustable air shutter. The main burner must be free from any debris accumulation that may effect burner operation (See Burner Cleaning Procedure on page 17).
