INSTALLATION
Gas requirements
This appliance must be installed by an authorised person,
according to all codes and regulations of:
• AS/NZS 5601.1 (particular attention to clause 6.10.1
and figure 6.3 on page 97, and clause 6.10.1.11)
The cookers come in two gas types: Natural gas and
Universal LPG. Before installation check that the cooker
is suitable for the gas supply. To do this check the gas
type on the carton sticker or on the data plate behind the
bottom of the oven door. The following table shows the
supply and operating pressures for various gas supplies.
GAS TYPE
Supply pressure at inlet to
appliance regulator (if fitted)
Operating pressure

WFG617
Operating pressure
at appliance test point for
WFE517, WFE616, WFE619
*Some models do not require an appliance regulator
for LPG operation, in which case the supply pressure
and operating pressure are the same. In such cases
the supply pressure is adjusted at a regulator in the
consumer piping, typically located at the cylinder.
The following table shows the injector sizes for each burner.
