Burner Inspection, Cleaning & Replacement - Bradford White LC2PV50H76N Service Manual

Condensing PV Series
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) The water heater vent is less than the allowable vent length.
b) The gas pressure is out of specification.
c) The pilot flame is not fully engulfing the spark/flame sensor.
The main burner should light smoothly from the pilot and burn with a blue flame and a minimum of
yellow tips.
The main burner must be free from any debris accumulation that may affect burner operation (see
burner cleaning procedure on page 17).
