the gas inlet. Check the burner ports and valve orifices for blockages. Burner ports can close over time due to
cooking debris and corrosion, use an opened paperclip or the supplied port maintenance bit to clean them.
Drill out blocked ports using this drill bit in a small cordless drill. The ports are easier to clean if the burner is
removed from the grill, but it can also be done with the burner installed. Do not flex the drill bit when drill-
ing 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!
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.
Protection Of Infrared Burners: The infrared burners of your grill are designed to provide a long service life,
though care must taken to prevent cracking of their ceramic surfaces. Fractures will cause the burners to
malfunction. The following provides a few of the causes of cracks and the steps you can take to avoid them.
Damage caused by failure to follow these steps is not covered by your grill warranty.
1. Impact with hard objects - Never allow hard objects to strike the ceramic. Take care when inserting or re-
moving cooking grates and accessories into or from the grill.
2. Contact with water or other liquids - Cold liquids contacting the hot ceramic surfaces can cause them to
break. Never throw water into the grill to douse a flame. If the ceramic or interior of a burner becomes wet
while not in use, later operation of the burner can create steam, which can produce sufficient pressure to crack
the ceramic. Repeated soaking of the ceramic can also cause it to swell and expand. This expansion causes
undue pressure on the ceramic that can cause it to crack and crumble.
i) Never throw water into the grill to control flare-ups.
ii) Do not attempt to operate the infrared burners in open air while raining.
iii) If you find standing water in your grill (because of exposure to rainfall, sprinklers, etc.), inspect the
ceramic for evidence of possible watersoaking. If the ceramic appears to be wet, remove the burner from the
grill. Turn it upside down to drain the excess water and bring indoors to dry thoroughly.
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 cook-
ing 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.
