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. Replace sear plate mount and tighten screws to complete reinstallation.
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.
WARNING!
Regulator Hose (when applicable): Check for abrasions', melting, cuts, and cracks in the
hose. If any of these conditions exist, do not use the gas grill. Have the part replaced by your Napoleon Gas
Grill dealer or qualified gas installer.
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.
