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 pan
with aluminum foil. Refer to cleaning instructions.
Burners burn with yellow
flame, accompanied by
the smell of gas.
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
burner, accompanied
by the smell of gas, and
possibly difficulties in
lighting.
Improper air shutter adjustment. Close air shutter slightly according to combustion air
adjustment instructions. (This must be done by a
qualified gas installer.)
Burner will not light with
the igniter, but will light
with a match.
Dead battery / or installed
incorrectly.
Loose electrode wire or switch
terminal wires.
Wrong replacement igniter.
Improper gap at electrode tip.
Lifting flames on burner.
Replace with heavy duty battery.
Check that electrode wire is firmly pushed onto the
terminal on the back of the igniter. Check that the
lead wires from the module to the ignition switch (if
equipped) are firmly pushed onto their respective
terminals.
One spark systems must use a one spark igniter.
Ensure that the collector box is tight and the gap
between the electrode end and the collector box is
between 1/8” - 3/16” (3mm-5mm). The gap can be
adjusted by bending the box in or out.
Close air shutter slightly - see previous problem.
Humming regulator. Normal occurrence on hot days. This is not a defect. It is caused by internal vibrations in
the regulator and does not affect the performance or
safety of the gas grill. Humming regulators will not be
replaced.
Burners will not cross
light each other.
Plugged ports along back of
burner.
Clean burner ports. See burner maintenance
instructions.
“Paint” appears to be
peeling inside lid or hood.
Grease build-up on inside
surfaces.
This is not a defect. The finish on the lid and hood is
porcelain, 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.
