Check that all burner valves are off
You will need: one burner control knob.
Valves are shipped in the OFF position, but you should
check to be sure. Put the knob on each valve. Check by
pushing down and turning clockwise. If they do not turn,
they are off, proceed to the next step. Figure 13.

Step 13
Check for gas leaks
Do not use an open flame to check for gas
leaks. Be sure there are no sparks or open
flames in the area while you check for
leaks. This will result in a fire or explosion
which can cause serious bodily injury or
death and damage to property.
WARNING: You should check for gas leaks every
time you disconnect and reconnect a gas fitting.
Note - All factory made connections have been thoroughly
checked for gas leaks. The burners have been flame
tested. As a safety precaution you should recheck all
fittings for leaks before using your Weber Gas Barbecue.
Shipping and handling may have loosened or damaged a
gas fitting.
WARNING: Perform these leak checks even if your
barbecue was dealer or store assembled.
You will need: a soap and water solution and a rag or
brush to apply it.
To perform leak checks: Slide back the collar of the quick
disconnect. Push male fitting of the hose into the quick
disconnect, and maintain pressure. Figure 14 (a). Slide
the collar closed. Figure 14 (b). If it does not engage or
lock, repeat procedure. Gas will not flow unless the quick
disconnect is properly engaged.

Turn on gas supply.
Check for leaks by wetting the connections with the soap
and water solution and watching for bubbles. If bubbles
form or if a bubble grows there is a leak.
Note - Since some leak test solutions, including soap and
water, may be slightly corrosive, all connections should be
rinsed with water after checking for leaks.
WARNING: Do not ignite burners when leak checking.
