Troubleshooting - Napoleon PRESTIGE 600RB User Manual

BURNER - The burner is made from heavy wall 304 stainless steel, but due to the extreme heat and corrosive environment,
surface corrosion will occur. Use a brass wire brush to remove surface corrosion. Clean any blocked ports using an opened
paper clip. Do not enlarge the burner ports. Spiders and insects are attracted to the smell of propane and natural gas. The
burner is equipped with an insect screen on the air shutter, which will reduce the
likelihood of insects building nests inside the burner, but does not entirely
eliminate the problem. The nest or web will cause the burner to burn with a soft
yellow or orange flame or cause a fire (flashback) at the air shutter underneath the
control panel. To clean the inside of the burner, it must be removed from the gas
grill. Remove the screw located in the center of each burner. Lift the back of the
burner upwards to remove. Use a flexible venturi tube cleaning brush to clean out
the inside of the burner. Shake any loose debris out of the burner, through the gas
inlet. Ensure that the insect screen is clean, tight, and free of any lint or other
debris. Check also that the valve orifices are clean. Do not enlarge the orifices.
Re-install the burner. Check that the valve enters the burner when installing.
Replace burner cover and mounting screws to complete installation.
ALUMINUM CASTINGS - Clean castings periodically with warm soapy water.
Aluminum will not rust, but due to high temperatures and weathering, oxidation can occur on aluminum surfaces. This will
appear as white spots on the castings. To refinish the castings, clean them and sand lightly with fine sandpaper. Wipe surface
to remove any residue, and paint with high temperature barbecue paint. Protect surrounding areas from over-spray. Follow
curing directions found on the can.
