Noises and Flare-ups
• Humming regulator.
• Excessive flare-ups and uneven heat.
Possible causes Solution
Normal humming noise on hot days.
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.
The cylinder valve was opened too quickly. Open cylinder valve slowly
Sear plates installed incorrectly.
Ensure sear plates are installed with holes towards the front, and
the slots on the bottom. See Assembly Instructions Guide.
Improper heating. Preheat grill with both main burners on high for 10 to 15 minutes.
Excessive grease and ash build on sear plates and in drip
pan.
Clean sear plates and drip pan regularly. Do not line pan with
aluminum foil. Refer to "Cleaning Instructions".
Gas Flow
• Low heat or low flame when valve is turned to high.
• Burners burn with yellow flame, accompanied by the smell of gas.
• Flames lift away from burner, accompanied by the smell of gas, and possible lighting difficulties.
• Burner output on HIGH, but setting is LOW. Rumbling noise and fluttering blue flame at burner surface.
Possible causes Solution
Propane – improper lighting procedure
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".
Natural gas – undersized supply line. Pipe must be sized according to installation code.
Leaking gasket surrounding the ceramic tile, or a weld
failure in the burner housing.
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.
Both gas propane and natural gas – improper preheating. Preheat grill with both main burners on high for 10 to 15 minutes.
