WARNING!
Always wear protective gloves and safety glasses when cleaning your grill.
WARNING!
Turn off the gas at the source and disconnect the unit before servicing. To avoid the
possibility of burns, maintenance should be done only when the grill is cool. A leak test must be performed
annually and whenever any component of the gas train is replaced or gas smell is present.
Maintenance Instructions
We recommend this gas grill be thoroughly inspected and serviced annually by a qualified service person.
At all times keep the gas grill area free from combustible materials, gasoline and other flammable vapors and
liquids. Do not obstruct the flow of ventilation and combustion air. Keep the cylinder enclosure ventilation
openings (located on the cart sides and at the front and back of the bottom shelf) free and clear from debris.
Combustion Air Adjustment: (This must be done by a qualified gas installer.) The air shutter is factory set and
should not need adjusting under normal conditions. Under extreme field conditions, adjustments might be
required. When the air shutter is adjusted correctly the flames will be dark blue, tipped with light blue and
occasionally yellow.
• With too little air flow to the burner, the flames are lazy yellow and can produce soot.
• With too much air flow, the flames lift erratically and can cause difficulties when lighting.
Adjusting the air shutter:
1. Remove cooking grids and sear plates and leave lid open. You may have to open the door or remove the
top drawer (if equipped) to access the air-shutter screw located at the mouth of the burner. The back cover
must be removed for rear tube burner air shutter adjustment.
2. Loosen air-shutter lock screw and open or close air shutter as required. The normal opening settings are:
Main Tube Burner
Propane 5/16” (8mm) Rear Tube Burner Propane Full Open
Natural 1/8” (3mm) Natural 1/8” (3mm)
*Infra-Red burners have no air adjustment.
3. Light the burners and set to high. Visually inspect burner flames. When the shutters are set correctly, turn
burners off, tighten locking screws, and replace removed parts. Ensure that the insect screens are installed.

Cleaning The Outer Grill Surface: Do not use abrasive cleaners or steel wool on any painted, porcelain or stainless
steel parts of your Napoleon Grill. Doing so will scratch the finish. Exterior grill surfaces should be cleaned with
warm soapy water while the metal is still warm to the touch. To clean stainless surfaces, use a stainless steel or
a non-abrasive cleaner. Always wipe in the direction of the grain. Over time, stainless steel parts discolor when
heated, usually to a golden or brown hue. This discoloration is normal and does not affect the performance of
the grill. 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 Grill dealer.
