Maintenance Instructions - Napoleon UP405 User Manual

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.
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
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
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.
