INSTALLATION
Wiring connection for gas cooker
To allow for disconnection of the appliance after
installation, the plug must be accessible after installation.
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified persons
in order to avoid a hazard.
Installing the gas cooker gas connection
Read these points before connecting to the gas supply:
• The cooker inlet connection point has a ½" BSP
external thread. See diagram below.
• An NG regulator or a LPG test point fitting is supplied.
• It is recommended to fit the regulator or test point fitting
to the appliance connection point, then fit either hard
piping or a high level flexible connection (AS/NZS
5601.1 clauses 5.9 and 6.10.1.9) which is then
attached to the consumer hard piping.
• Ensure installation allows withdrawal of appliance.

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
at appliance test point
for 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.
