WARNING! Hose: 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.
