Out of propane
Blockage in the gas

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).
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.
WARNING: Never take a propane cylinder indoors for any pur-
pose.
For safety, the regulator coupling on your barbecue is
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.
