Napoleon Grills MIRAGE 730 - Manual (Page 8)

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 5/32"
Natural 5/32"
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. Ensure that the insect screens are installed.
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.
GRIDS AND WARMING RACK - The grids and warming rack are best cleaned during the pre-heat period with a soft brass
wire brush. Steel wool can be used for stubborn stains. Stainless grids will discolour permanently from normal usage, due
to the high temperature of the cooking surface.
CLEANING INSIDE THE GAS GRILL - Remove cooking grids. Use a soft brass wire brush to clean loose debris from casting
sides and insides of the lid. Scrape sear plates with a putty knife or scraper, and use a wire brush to remove ash. Remove
sear plates and brush debris off of burners with a brass wire brush. Brush all debris from inside the gas grill into the
removable drip pan. Ensure that the sear plates are placed properly when they are reinstalled (Check assembly instructions
for proper orientation).
DRIP PAN - Slide the drip pan out for easy cleaning. It should be cleaned frequently (every 4-5 uses) to avoid grease
buildup. Grease and excess drippings pass through to the drip pan, located under the gas grill, and accumulate in the
disposable grease tray below the drip pan. Accumulated grease can cause a fire hazard. Do not line the drip pan with
aluminum foil or sand, as it can prevent the grease from flowing properly. The pan should be scraped out with a putty knife or
scraper, and all the debris should be scraped into the disposable grease tray. This tray should be replaced every two to four
weeks, depending on gas grill usage. For supplies, see your Napoleon Gas Grill dealer.
MAINTENANCE/CLEANING INSTRUCTIONS
It is recommended that this gas grill be thoroughly inspected and serviced annually by a
qualified service person.
Ensure that the burners are turned off prior to cleaning. Avoid unprotected contact with hot surfaces. Clean grill in an
area where cleaning solutions will not harm decks, lawns or patios. Do not use oven cleaner to clean any part of this gas
grill. Do not use a self cleaning oven to clean cooking grids or any other parts of the gas grill. Barbecue sauce and salt
can be corrosive and will cause rapid deterioration of the gas grill components unless cleaned regularly.
• Do not use pressure washer to clean any part of the unit.
