Grids And Warming Rack

: The grids and warming rack are best cleaned with a brass wire brush during the 

pre-heating period. Steel wool can be used for stubborn stains. It is normal that stainless grids (if equipped) 

will discolor permanently from regular usage due to the high temperature of the cooking surface.

Control Panel

: The control panel text is printed directly on the stainless steel and with proper 

maintenance will remain dark and legible. To clean the panel, use only warm soapy water or stainless steel 

cleaner available from your Napoleon dealer. Never apply abrasive cleaners on any stainless surfaces, 

especially the printed portion of the control panel or the printing will gradually rub off. 

Cleaning Inside The Gas Grill

: Remove the cooking grids. Use a brass wire brush to clean loose debris from 

the casting sides and underneath the lid.  Scrape the sear plates with a putty knife or scraper, and use a 

wire brush to remove the ash. Remove the sear plates and brush debris from the burners with the brass 

wire brush. Sweep all debris from inside the gas grill into the drip pan. 

WARNING!

 Accumulated grease is a fire hazard.

Drip Pan

:  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 drip pan, located beneath the gas grill and accumulate 

in the disposable grease tray below the drip pan.  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 Napoleon 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 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. 

WARNING!

 Hose: Check for abrasions, melting, cuts, and cracks in the hose. If any of these 

conditions exist, do not use the gas grill. Have the part replaced by your Napoleon Gas Grill dealer or 

qualified gas installer.

WARNING!

 When reinstalling the burner after cleaning it is very 

important that the valve/orifice enters the burner tube before lighting your 

gas grill. If the valve is not inside the burner tube a fire or explosion could 

occur.

Tube Burner

: The burners are 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 Universal Liquefied Petroleum Gas 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 beneath the 

control panel. To clean the inside of the burner, it must be removed from the gas grill: Remove the screw 

that attaches the burner to the back wall.  Slide the burner back and upwards to remove.  Cleaning: Use 

a flexible venturi tube brush to clean the inside of the burner. Shake any loose debris from the burner 

through the gas inlet. Check the burner ports and valve orifices for blockages. Burner ports can close over 

time due to cooking debris and corrosion, use an opened paperclip or the supplied port maintenance bit 

to clean them.  Drill out blocked ports using this drill bit in a small cordless drill. The ports are easier to 

clean if the burner is removed from the grill, but it can also be done with the burner installed. Do not flex 

the drill bit when drilling the ports, as this will cause the drill bit to break. This drill is for burner ports only, 

not for the brass orifices (jets) which regulate the flow into the burner. Take care not to enlarge the holes.  

Ensure the insect screen is clean, tight, and free of any lint or other debris.

Reinstallation

: Reverse the procedure to reinstall the burner. Check that the valve enters the burner when 

installing.
