Remove the four outward screws on the back of the heater and slide the outer frame upwards and off. You will find two screws one on each end underneath the third bar at the FRONT of the heater. Caution is needed as the screws are held by a clipon screw washer and they are easy to lose. To reassemble (which is easier said than done) aligne the screws from the outside first and make sure the clips are in place over the holes. Screw the two back. Slide the frame back and screw the four outer screws back. This might need a tight fit between the frame and the lower groove in the fire. Hope this helps.
