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 15).
