Troubleshooting - Napoleon PRESTIGE 500 Instructions Manual

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.
