Natural Gas
Natural gas installation should only be carried out by a qualified technician.
Fit the natural gas regulator that was supplied with your grill directly to the
grill inlet located on the right side of the grill. You can do this using either
hard plumbing or a flexible hose connected to a bayonet point.
Refer to local installation code for pipe sizing details. Secure all joints spanner
tight but do not over- tighten.
Test gas pressure by removing the last burner from the left hand side of the grill
and attaching a hose and pressure gauge to the end of the gas valve. Turn on 2
burners and check the pressure. Inlet pressure should be 4.0" WC or 1.00 kPa.
For mobile trolley installations that use flexible hosing to connect to natural
gas, a chain or similar restraining device must be fitted to prevent strain on
the gas supply line. One end of the chain should attach to the grill; the other
end should attach to a fixed structural point close to where the hose connects
to the gas piping. The chain must be at least 30% shorter than the gas supply
line. In this way, if the grill is accidentally moved, the chain stops the grill from
stretching the hose.
The grill must be isolated from the gas supply piping system by closing its
manual shut off valve during any pressure testing of the gas supply piping
system.
