b. The Supply Pressure required for this appliance is shown in the 'Specifications' Section of this
manual. Check the gas supply to ensure that adequate supply pressure exists.
c. The Input Rate of this appliance is shown on the Rating Plate and in the 'Specifications' section of
this manual. The input rate should be checked against the available supply line capacity. Particular
note should be taken if the Barbeque is being added to an existing installation.
NOTE: It is important that adequately sized piping runs directly to the connection joint on the
appliance with as few tees and elbows as possible to give maximum supply volume.
3. Fit the gas regulator supplied, into the gas supply line as close to the appliance as possible.
The regulator connections are ¾" BSP female.
The connection is ¾" BSP male.
(Refer to the ‘Specifications’ section for the gas supply location dimensions).
