Burner Maintenance
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 unsta- ble 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. After 5 minutes of operation the burner screen will become radiant and the flame will soften and turn or- ange. If the burner screen does not become radiant after 5 minutes of op- eration it must be cleaned (see burner cleaning procedure below).
