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

Improper air shutter adjustment. Close air shutter slightly according to
combustion air adjustment instructions.

Loose electrode wire or switch terminal
wires.

Check that electrode wire is firmly pushed
onto the terminal on the back of the
igniter. Check that the lead wires from the

One spark systems must use a one spark
igniter.

5mm). The gap can be adjusted by bending
the box in or out.
Close air shutter slightly - see previous

light each other.
Plugged ports along back of burner. Clean burner ports. See burner
