TYPE OF GAS
Your natural gas grill is factory built to operate using natural gas only . Never attempt to
operate your grill on gases other than the type specified on the grill rating plates .
Your grill operates at 7" of water column pressure. If replacement of the hose becomes
necessary, factory specified parts are required . See your local dealer .
For safety and design reasons, the conversion of a Weber
Natural gas to operation using LP gas is not allowed .
WHAT IS NATURAL GAS?
Natural gas, often called methane, is a safe modern fuel . Natural gas is supplied by your
local utility and should be readily available if your house is already heated with gas .
NATURAL GAS CONNECTION
Uncoil the NG supply hose and route the end out the access hole at the back panel of
the cabinet (1). The 330 unit requires a 1/2" hose as opposed to the 3/8" hose for the
310 & 320 . Weber
recommends moving the grill at least 24" from the gas supply and
®
any combustible surfaces . After the gas supply has been run and checked for leaks in
accordance to the assembly instructions, you are ready to grill . To connect the hose
to the gas supply, pull back the outer fitting, insert the hose fitting all of the way, and
release the outer fitting . This process will produce a gas joint .
LEAK CHECK PREPARATION
Check that all Burner Valves are Off
Valves are shipped in the OFF position, but you should check to be sure that they are
turned off . Check by pushing in and turning clockwise . If they do not turn, they are off . If
they do turn continue turning them clockwise until they stop, then they are off .
Check the Flexible Hose to Manifold Connection
The natural gas hose was attached during the manuafacturing process . We do
recommend that the hose to gas manifold connnection be leak tested, following
guidelines in this Owner's Guide, prior to barbecue operation .
To perform leak checks: Slide back the collar of the quick disconnect (2) . Push male
fitting of the hose into the quick disconnect, and maintain pressure . Slide the collar
closed (3) . If it does not engage or lock, repeat procedure . Gas will not flow unless the
quick disconnect is properly engaged .
