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.)
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.
