TUBE 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.
MAINTENANCE/CLEANING INSTRUCTIONS
INFRA RED BURNER - Because of the high intensity of the infrared burner, most drippings and food particles that fall onto the
burner surface are immediately incinerated. However, some debris and residue may remain. To remove this residue after
cooking, turn the grill on high with lid closed for 5-10 minutes. Never use a brush or pressure washer to clean the infra red
burners.
HOSE - Check for abrasion, melting, cuts and cracks. If any of these conditions exist, do not use gas grill. Have part
replaced by your Napoleon Gas Grill dealer, or qualified gas installer.
CLEANING THE OUTSIDE OF THE GAS GRILL - Do not use abrasive cleaners to clean any painted, porcelain or stainless
steel parts. Porcelain enamel components must be handled with additional care. The baked on enamel finish is glass like,
and will chip if struck. Touch-up enamel is available from your Napoleon Gas Grill dealer. Exterior grill surfaces should be
cleaned while warm to the touch, with warm soapy water. To clean stainless surfaces, use a stainless steel cleaner or a non-
abrasive cleaner. Always wipe in the direction of the grain. Do not use steel wool, as it will scratch the finish. Stainless steel
parts will discolour when heated, usually to a golden or brown colour. This discolouration is normal and will not affect the
performance of the grill.
It is very important when re-installing the burner after
cleaning 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
CAUTION BEWARE OF SPIDERS
PROTECTION OF YOUR INFRA RED BURNERS - The infrared burners of your grill are designed to provide a long service life.
However, there are steps you must take to prevent cracking of their ceramic surfaces, which will cause the burners to malfunc-
tion.
1. Never let water come in direct contact with your ceramic burner.
2. Avoid impact with hard objects.
3. In order 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 may become deprived of oxygen, causing them to crack. Do not cover more than 75% of the cooking
surface with solid metal (ie. griddle or large pan).
Damage caused by failure to follow these steps is not covered by your grill warranty.
IMPORTANT
• Do not allow cold water (rain, sprinkler, hose, etc.) to come in contact with hot ceramic burners. A large
temperature differential can cause cracking of the ceramic tile.
