| Troubleshooting
Solution
Ensure lighting procedure is followed carefully. All gas valves must
be in the OFF position when the tank valve is turned on. Turn tank
on slowly to allow pressure to equalize. See Operation – "Lighting
Instructions".
Pipe must be sized according to installation code.
Allow burner to cool and inspect very closely for cracks. Contact
your authorized Napoleon dealer to order replacement burner
assembly if any cracks are found.
Preheat grill with both main burners on high for 10 to 15 minutes.
Thoroughly clean nest or webs out of your burner orifice by
removing it and following instructions in this manual.
See "Leak Test".
Open or close air shutter slightly according to this manual.
See "Maintenance Instructions".
IMPORTANT! This must be done by a qualified gas installer.
Check gas level in propane cylinder.
Reposition supply hose as necessary.
Turn the burners off and close the tank valve, wait a minute before
fully re-opening the valve, allow a few seconds for the pressure
to equalize before following the Lighting Instructions to start the
grill. Ensure igniting procedure is followed carefully every time you
cook. All gas valves must be OFF when the tank valve is turned
on. Always open the tank valve slowly.
Solution
Turner burner OFF and allow to cool for at least 2 minutes.
Reignite burner and burn on HIGH for at least 5 minutes, or until
the ceramic tiles are evenly glowing red.
Ensure no more than 75% of the grill surface is covered by
objects or accessories. Turn burner OFF and allow to cool for at
least 2 minutes. Reignite.
Allow burner to cool and inspect very closely for cracks. Contact
your authorized Napoleon dealer to order replacement burner
assembly if any cracks are found.
Preheat grill with both main burners on high for 10 to 15 minutes.
Clean sear plates and drip pan regularly. Do not line pan with
aluminum foil. Refer to "Cleaning Instructions".
Solution
This is not a defect. The finish on the lid and hood is porcelain
or stainless steel and will not peel. The peeling is caused by
hardened grease, which dries into paint-like shards, that flake off.
Regular cleaning will prevent this. See "Cleaning instructions".
