4.Air Shutter Adjustment

TOOLS REQUIRED: Standard flat blade screwdriver.

The efficiency of the oven depends on a delicate balance between the air supply and the volume of gas. Whenever this balance is disturbed, poor operating characteristics and excessive gas consumption will occur.

The gas mixer balance is controlled by an air shutter on the front of the oven burner. A yellow streaming flame on the burner is an indication of insufficient air. To correct this condition, loosen the screw locking the shutter into position. Rotate the air shutter open until the burner flame begins to lift from the burner, then close the shutter slightly down again and lock it into place (Fig’s. 5 & 6).
