Burner Inspection, Cleaning & Replacement - Bradford White PV Series Service Manual

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.
Pilot flame should be stable, some causes for an unstable pilot flame are:
a) Water heater vent is less than the allowable vent length.
b) Gas pressure is out of specification.
c) Pilot flame not fully engulfing spark/flame sensor.
Main burner should light smoothly from pilot and burn with a blue flame with a minimum of yellow
tips.
Main burner must be free from any debris accumulation that may affect burner operation (see
burner cleaning procedure on page 18).
