Napoleon PRESTIGE II 450 Installation And Operating Instructions Manual page 11

3. Impaired ventilation of hot air from the grill - For the burners to function properly, hot air must have a way
to escape the grill. If the hot air is not allowed to escape, the burners can become deprived of oxygen causing
them to back-flash. If this occurs repeatedly, the ceramic could crack. Never cover more than 75% of the cooking
surface with solid metal (i.e., griddle or large pan).
4. Incorrect cleaning - Do not clean the ceramic tile with a wire brush. If debris is collecting on your burner,
light the burner and operate on high for 5 minutes with the lid open, allowing debris to burn off.
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.
