Troubleshooting Guide

PROBLEM POTENTIAL CAUSE
Burner will not light
Gas supply turned off
Out of propane
Blockage in the gas system
Misalignment of the gas valve to
the venturi tubes of the burner.
Improper attachment of the
propane hose and regulator
Unit won't heat up (LP)
Control knob left open at startup,
turning gas on too quickly
Wind
Unit won't stay lit
Running out of fuel
Turn on fuel supply and retry.
Confirm the flow of gas by smell or by listening for the hiss
of gas being emitted. Allow gas to clear before attempting to
relight.
Weigh your propane cylinder. A standard 20 lb. cylinder
will weigh about 18 lb. when it is empty and 38 lb. when it
is 80 % full.
WARNING: Never take a propane cylinder indoors for any
purpose.
Confirm that the venturi tubes are not blocked by insects or
other debris. Use a special venturi brush to clean (Fig. 16).
Use a pin or needle to carefully probe the orifice in the gas
valve. Never enlarge the orifice (Fig. 18).
Look under the front control panel and reinsert the gas
injector into the venturi tube, if required (Fig. 22).
Tighten the regulator's plastic collar onto the cylinder valve.
Hand-tighten only (Fig. 4).
For safety, the regulator coupling on your barbecue is
or
equipped with a flow control mechanism. This device limits
gas flow in the event of a sudden change in the demand for
gas. This may be engaged inadvertently, if a burner control
knob should be left ON when you open the propane cylinder
valve. Rapidly opening the valve can also engage flow control.
To resolve the problem, close your cylinder valve. Confirm that
all burner control knobs are in the OFF position. Open the
cylinder valve slowly (about 1 to 2 turns) and wait 5 seconds.
Finally, turn a single burner ON and try relighting it.
Always shelter your Grill from strong winds.
Confirm the flow of gas by smell, or by listening for the hiss
of gas being emitted.
Weigh your propane cylinder. A standard 20 lb. cylinder will
with about 18 lb. when it is empty ad 38 lb. when it is 80% full.
