MAIN BURNER: Inspection, Adjustment, Cleaning and Replacement
At periodic intervals (not more than 6 months) a visual inspection should be made of the main burner for
proper operation and to ensure no debris accumulation.
Main burner should light smoothly from pilot and burn with a blue flame with a minimum of yellow tips.
Steel burner models have a self-adjusting air mixture and do not have an adjustable air shutter.
Main burner must be free from any debris accumulation that may affect burner operation (see burner cleaning
procedure on page 36).
Under NO circumstances should flammable materials be used or stored in the vicinity of the water
heater. With the inner door removed the Bradford White Defender Safety System will be
deactivated. If flammable vapors are present, a fire or explosion may result causing property
damage, personal injury, or death.
Inner door and burner components may be HOT when performing this
operation. Take necessary precaution to prevent personal injury.
