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 insure no debris accumulating.
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 32).
Under no circumstances shall 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 inactivated. If flammable
vapors are present, a fire or explosion may result causing property damage, personal injury or death.
Upon completion of the cast iron burner adjustment procedure, the inner door must be replaced per
SERVICE PROCEDURE RG-1, steps 4 through 14 to reactivate Bradford White Defender Safety System.
Inner door and burner components may be HOT when performing this operation. Take necessary
Step 1. With main burner in operation, remove right side inner door per SERVICE PROCEDURE I, steps
3b & 3c. Be sure to maintain wire connection to resettable thermal switch for this adjustment
procedure.
Step 2. To adjust for proper burning, loosen the air shutter nut, rotate the shutter to close the opening in the
burner, then slowly rotate the shutter until the yellow tips disappear and the flame becomes blue.
Tighten the air shutter nut. Too much air will cause the flame to lift off the burner ports and create
noisy burner operation. Too little air (yellow tips) will result in soot formation.
Place right side inner door into proper position to confirm proper burner flame pattern and correct
air shutter adjustment. It may be necessary to allow the burner to operate for several minutes for
burner flame to stabilize.
