The gas/air balance is controlled by an air shutter on the front of the top 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. 2 & 3).
