Napoleon Grills UP405 manual Maintenance Instructions, Yellow Tipping Approximately Dark Blue

MAINTENANCE INSTRUCTIONS

It is recommended that this gas grill be thoroughly inspected and serviced annually by a qualified service person.

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.

BURNER

LIGHT BLUE BURNER PORT

YELLOW TIPPING

	APPROXIMATELY
DARK BLUE	1/2"

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	3/16"	Back Burner	Propane	3/8"
	Natural	1/8"		Natural	1/8"

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 gas grill dealer, or qualified gas installer.

	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 2 screws located above the burner to the left and right of
	the centre of 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.
	ALUMINUM CASTINGS - Clean castings periodically with warm soapy water. Aluminum will not rust, but due to high temperatures
	and weathering, oxidation can occur on aluminum surfaces. This will appear as white spots on the castings. To refinish the
8	castings, clean them and sand lightly with fine sandpaper. Wipe surface to remove any residue, and paint with high temperature
	barbecue paint. Protect surrounding areas from over-spray. Follow curing directions found on the can.
