Maintenance Instructions - Napoleon Ultra chef UD405RSB User Manual

Drip Pan: Accumulated grease is a fire hazard. Clean the drip pan frequently (every 4 – 5 uses or as often
as required) to avoid grease buildup. Grease and excess drippings pass through to the grease tray, located
beneath the gas grill and accumulate in the disposable grease tray below the grill. To access the disposable
grease tray or to clean the drip pan, slide the drip pan free of the grill. Never line the drip pan with aluminum
foil, sand or any other material as this could prevent the grease from flowing properly. The pan should be
scraped out with a putty knife or scraper. Replace the disposable grease tray every 2 – 4 weeks, depending on
gas grill usage. For supplies, see your Ultra Chef Gas Grill dealer.
Cleaning The Outer Grill Surface: Do not use abrasive cleaners or steel wool on any painted, porcelain or stainless
steel parts of your Ultra Chef 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 Ultra Chef Grill dealer.

Maintenance Instructions

We recommend this gas grill be thoroughly inspected and serviced annually by a qualified service person.
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.
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. The back cover must be removed for rear tube
burner air shutter adjustment.
2. Loosen air-shutter lock screw located at the mouth of the burner and open or close air shutter as required.
The normal opening settings are:
Main Tube Burner Propane 3/16" (5mm)
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.

Burner: The burner is made from heavy wall 304 stainless steel, but extreme heat and a corrosive environment
can cause surface corrosion to occur. This can be removed with a brass wire brush.
CAUTION!
Beware of Spiders.
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 reduces the likelihood of insects building nests inside the burner but
does not entirely eliminate the problem. A nest or web can 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 screw (s) that attaches the burner to the back
wall. Slide the burner back and up wards to remove.
