GAS SUPPLY
■ The connection must be performed by an authorised person according to the relevant
standards.
■ Before connecting the appliance to the gas main, mount the brass conical adaptor
onto the gas inlet pipe, upon which the gasket has been placed (figs. 10 - 11).
Conical adaptor and gasket are supplied with the appliance (packed with conversion
kit for use with Natural gas or ULPG).
■ This appliance is suitable for use with Natural Gas or ULPG (Check the “gas type”
sticker attached to the appliance).
■ For Natural Gas models the gas supply is connected to the pressure regulator which is
supplied with the appliance (fig. 11). Adjust the regulator to obtain a test point pressure
of 1 kPa with the two semi-rapid (SR) burners operating at maximum.
■ For ULPG models the gas supply is connected to the test point adaptor which is
supplied with the appliance (fig. 10) and ensure that the supply pressure is regulated
to 2.75 kPa.
■ The connection must be made at the rear of appliance; the pipe does not cross the
cooker (fig. 12).
■ The inlet not used must be closed off with the cap and sealing gasket supplied.
■ IMPORTANT: Use two spanners to tighten or loosen the connecting pipe (fig. 13).
INSTALLATION WITH A FLEXIBLE HOSE ASSEMBLY
■ If this appliance has to be installed with a hose assembly, the installer shall refer to the
network operator or gas supplier for confirmation of the gas type, if in doubt.
■ When used with a flexible hose, the connector on the wall should be between 450
mm to 500 mm from the floor and 200 mm to 300 mm from the left-hand side of the
appliance as viewed from the front. The hose connection on the appliance shall face
downwards.
■ It is important that the hose does not come in contact with the metal of the appliance
and is secured as per appropriate gas installation codes.
A chain 80% of the length of the flexible gas hose must be used to prevent stress
being applied to the hose. The chain should be attached securely to the product where
shown, and on the wall.
■ Flexible hose assemblies should be AS/NZS 1869 Class B or Class D certified.
The thread connection shall be Rp ½” (ISO 7-1) male.
■ IMPORTANT WARNING: After connection the installer must check that the hose
is not kinked, subjected to abrasion or permanently deformed.
The installer must check also that the hose is not near (or in contact) with any
hot surfaces.
■ The hose assembly shall be as short as practicable and comply with relevant
AS5601 / NZS5261 requirements.
LEAK-TESTING AND FLAME-TESTING THE COOKER
1. After connecting the gas supply, check the piping and connections for leaks
using a soap and water solution. The presence of bubbles indicates a leak,
tighten or replace connections as appropriate.
Warning: Do not use any naked flame to check for leaks.
