Troubleshooting - Napoleon N415-0183 Owner's Manual

BURNER - The burner is made from heavy wall 304 stainless steel, but due to the extreme heat and corrosive environment,
surface corrosion will occur. Use a brass wire brush to remove surface corrosion. Clean any blocked ports using an opened
paper clip. Do not enlarge the burner ports. Spiders and insects are attracted to the smell
of propane and natural gas. The burner is equipped with an insect screen on the air
shutter, which will reduce the likelihood of insects building nests inside the burner, but
does not entirely eliminate the problem. The nest or web will cause the burner to burn
with a soft yellow or orange flame or cause a fire (flashback) at the air shutter underneath
the control panel. To clean the inside of the burner, it must be
removed from the gas grill. Remove the screw(s) located above the
burner to the left and right of the centre of the burner on 450 models.
Lift back of burner upwards to remove. Use a flexible venturi tube
cleaning brush to clean out the inside of the burner. Shake any loose
debris out of the burner, through the gas inlet. Ensure that the insect
screen is clean, tight, and free of any lint or other debris. Check also
that the valve orifices are clean. Do not enlarge the orifices. Re-
install the burner. Check that the valve enters the burner when
installing. Replace burner cover and mounting screws to complete
installation.
ALUMINUM CASTINGS - Clean castings periodically with warm
soapy water. Aluminum will not rust, but due to high temperatures
and weathering, oxidation can occur on aluminum surfaces. This will appear as white spots on the castings. To refinish the
castings, clean them and sand lightly with fine sandpaper. Wipe surface to remove any residue, and paint with high
temperature barbecue paint. Protect surrounding areas from over-spray. Follow curing directions found on the can.

TROUBLESHOOTING

Problem
Low heat / Low flame when
valve turned to high.
Excessive flare-ups/uneven
heat.
Burners burn with yellow
flame, accompanied by the
smell of gas.
Flames lift away from burner,
accompanied by the smell of
gas, and possibly difficulties
in lighting.
Possible Causes
For propane - improper lighting
procedure.
For natural gas - undersized sup-
ply line.
For both gases - improper preheat-
ing.
Sear plates installed incorrectly.
Improper pre-heating.
Excessive grease and ash build up
on sear plates and in drip pan.
Possible spider web or other debris,
or improper air shutter adjustment.
Improper air shutter adjustment.
Screw
Solution
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.
Pre-heat grill with all main burners on high for 10 to 15 min-
utes.
Ensure sear plates are installed with the holes towards the
front, and the slots on the bottom. See assembly instructions.
Pre-heat grill with all main burners on high for 10 to 15
minutes.
Clean sear plates and drip pan regularly. Do not line pan
with aluminum foil, sand or any other material, as it can
prevent the grease from flowing properly. Refer to cleaning
instructions.
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.)
Close air shutter slightly according to combustion air
adjustment instructions.
(This must be done by a qualified gas installer.)
