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. Insect
nests or webs 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 nut located underneath the burner support at the center of
the curve in the burner. Lift back of 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.

Turn off the gas at the source and disconnect unit before servicing. Maintenance should only be done when the grill is
cool, to avoid the possibility of burns. A leak test must be performed annually, and whenever any component of the gas
train is replaced.
COMBUSTION AIR ADJUSTMENT - (This must be done by a qualified gas installer.) The air shutter is factory set and
should not have to be adjusted under normal conditions. However, some extreme field conditions may exist that require
adjustment. When the air shutter is adjusted correctly, the flames will be dark blue with light blue tips, and occasional yellow tips.
YELLOW TIPPING
If the burner is getting too little air, the flames will be lazy yellow, and possibly produce soot. If the burner is getting too much
air, the flames will be lifting erratically from the burner and may cause difficulties when lighting.
1. To adjust the air shutter, remove cooking grids and sear plates and leave lid open. The back cover must be removed for
back burner air shutter adjustment.
2. Loosen air-shutter lock screw and open or close air shutter as required. The normal settings are:
Main Burner
Propane
Full Open
Natural
Full Open
3. Light burners and set to high. Visually inspect burner flames. When shutters are set, turn burners off, tighten locking
screw, and replace removed parts.
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.
