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.)
Rear and Side burners will not
light with the igniter but will light
with a match.
Dead battery / or installed incorrectly.
Loose electrode wire or switch terminal wires.
Lifting flames on burner.
Replace with premium 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.
Close air shutter slightly - see previous problem.
Main burner will not light with
the igniter but will light with a
match.
Jet-fire outlet is dirty or clogged.
Clean jet-fire outlet with a soft bristle brush.
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.
Dirty or corroded cross light brackets.
Clean or replace as required.
“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.
Burner output on “high” setting
is too low. (Rumbling noise and
fluttering blue flame at burner
surface.)
Lack of gas.
Supply hose is pinched.
Dirty or clogged orifice.
Spider webs or other matter in venturi tube.
Propane regulator in “low flow” state.
Check gas level in propane cylinder.
Reposition supply hose as necessary.
Clean burner orifice.
Clean out venturi tube.
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.
