Remove cooking grids and sear plates and leave lid open. You may have to open the door or removethe top drawer (if equipped) to access the air-shutter screw located at the mouth of the burner. The backcover must be removed for rear tube burner air shutter adjustment.2. Loosen air-shutter lock screw and open or close air shutter as required.
