ACTION REQUIRED
WARNING:
WARNING:
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 19 lb. when it is empty
and 39 lb. when it is 80 % full.
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. 15).
Use a pin or needle to carefully probe the orifice in
the gas valve. Never enlarge the orifice (Fig. 16).
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 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 19 lb. when it is empty ad
39 lb. when it is 80% full.
Never take a propane cylinder
