of the burner. Shake any loose debris from the burner through the gas inlet. Check the burner ports and valve orifices for blockages. Burner ports can close over time due to cooking debris and corrosion, use an opened paperclip or the supplied port maintenance bit to clean them. Drill out blocked ports using this drill bit in a small cordless drill. The ports are easier to clean if the burner is removed from the grill, but it can also be done with the burner installed. Do not flex the drill bit when drilling the ports, as this will cause the drill bit to break. This drill is for burner ports only, not for the brass orifices (jets) which regulate the flow into the burner. Take care not to enlarge the holes. Ensure the insect screen is clean, tight, and free of any lint or other debris.

Reinstallation: Reverse the procedure to reinstall the burner. Check that the valve enters the burner when installing.

Warning! When reinstalling the burner after cleaning it is very important that the valve/orifice enters the burner tube before lighting your gas grill. If the valve is not inside the burner tube a fire or explosion could occur.

Aluminum Castings: Clean castings periodically with warm soapy water. Aluminum will not rust, but high temperatures and weathering can cause oxidation to occur on aluminum surfaces. This appears as white spots on the castings. To refinish these areas, clean first and sand lightly with fine sandpaper. Wipe the surface to remove any residue and paint with high temperature barbecue paint. Protect surrounding areas from over-spray. Follow the manufacture’s directions for curing.
