Manual Lighting
Failure to open lid while igniting the
barbecue, or not waiting 5 minutes to
allow the gas to clear if the barbecue
does not light, may result in an explosive
flame-up which can cause serious bodily
injury or death.
1) Open the lid. Figure 2.
2) Check that fuel scale reads more than "E".
Note - E = empty; F = full.
3) Make sure all burner control knobs are turned OFF.
(Push each knob down and turn clockwise.)
WARNING: The burner control knobs must be in the
OFF position before turning on the LP tank valve. If
they are not in the OFF position, when you turn on the
LP tank valve, the excess flow control will activate,
limiting the flow of gas from the LP tank. If this should
occur, turn OFF the LP tank valve and burner control
knobs and start over.
When the excess flow control is
activated, a small amount of gas is still
flowing to the burners. After turning OFF
the tank and burner control knobs, wait
at least 5 minutes for the gas to clear
before attempting to light the barbecue.
Failure to do so may result in an
explosive flame-up which can cause
serious bodily injury or death.

the gas clear before you try again or try to light with a
match.

burner.
Note - Always light the FRONT burner first. The other
burner ignites from the FRONT burner.
