Solution
TM
Clean JETFIRE outlet with a soft bristle brush.
Clean or replace as required.
Replace with premium heavy- duty battery.
Check electrode wire is firmly pushed onto the terminal on the
back of the igniter. Check the lead wires from the module to the
ignition switch (if equipped) are firmly pushed onto their respective
terminals.
Close air shutter according to "Maintenance Instructions"-
Combustion Air Adjustment section in this Owner's Manual.
IMPORTANT! This must be done by a qualified gas installer.
Solution
This isn't a defect. It's caused by internal vibrations in the regulator
and doesn't affect the performance or safety of the grill. Humming
regulators WILL NOT be replaced.
Open cylinder valve slowly
Ensure sear plates are installed with holes towards the front, and
the slots on the bottom. See Assembly Instructions Guide.
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
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".
