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.
Aluminum Castings: Clean castings periodically with warm soapy water. Aluminum will not rust, but high
temperatures and weathering can cause oxidation to occur on aluminum surfaces. This appears as white spots
on the castings. To refinish these areas, clean first and sand lightly with fine sandpaper. Wipe the surface to
remove any residue and paint with high temperature barbecue paint. Protect surrounding areas from over-spray.
Follow the manufacture’s directions for curing.
Troubleshooting
Problem Possible Causes Solution
Low heat / Low flame
when valve turned to high.
For propane - improper lighting
procedure.
For natural gas - undersized supply
line.
For both gases - improper preheating.
Ensure lighting procedure is followed carefully. All
gas grill valves must be in the off position when the
tank valve is turned on. Turn tank on slowly to allow
pressure to equalize. See lighting instructions.
Pipe must be sized according to installation code.
Preheat grill with both main burners on high for 10 to
15 minutes.
Excessive flare-ups/uneven
heat.
Sear plates installed incorrectly.
Improper preheating.
Excessive grease and ash build on
sear plates and in drip pan.
Ensure sear plates are installed with the holes
towards the front and the slots on the bottom. See
assembly instructions.
Preheat grill with both main burners on high for 10 to
15 minutes.
Clean sear plates and drip pan regularly. Do not line

Possible spider web or other debris,
or improper air shutter adjustment.
Thoroughly clean burner by removing. See general
maintenance instructions. Open air shutter slightly
according to combustion air adjustment instructions.
(This must be done by a qualified gas installer.)
Flames lift away from

by the smell of gas, and
possibly difficulties in

in the regulator and does not affect the performance
or safety of the gas grill. Humming regulators will not
be replaced.
