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

accompanied by the
smell of gas.
Possible spider web or

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.)

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

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.
