remain accessible after installation of the appliance.
Important note:
This appliance is connected to the mains (240 VAC) by
means of the connecting lead which must be fixed to the
kitch en un it to pre ven t it f rom c omi ng i nto c ont act wi th h ot
parts of the cooktop (or an oven installed underneath)
and remain accessible after installation of the cooktop.
When making this connection make sure that the lead
cannot come into contact with hot parts of the cooktop.
Important: This appliance must be earthed. When
connecting the cooktop ensure that the earth wire is
connected first and that all wires are connected to the
correct terminals. Fig. 4.
Gas
During the planning stage, consider the position of supply
connections.
The cooktop must be connected to the gas supply with
upstream connection of an isolation valve in accordance
with the respectively valid regulations. We recommend
that the isolation valve be fitted prior to the cooktop to
enable isolation of cooktop from gas supply. The valve
must be easily accessible at all times.
Fig. 3a
Fig. 4

13
To find out the factory set gas type, see bottom of
cooktop next to gas connection.
Remove plastic cap from gas supply line prior to
installation.
Fit regulator (N.G.) or a test point (Propane gas) directly
to the R 1/2’’ connection as per Fig. 5. and Fig. 6.
Direction of gas flow is indicated on the rear of the
regulator.
For position of the inlet connection refer Fig.1.
Use pipe compound or thread sealant, properly theaded
pipes and careful assembly procedure so that there is no
cross threading, etc., which might cause damage or
leakage.
Make sure that all connections peformed are free of
leakage.
The manufacturer does not accept any liability for
leakage on connections performed by the installer or if
the L-tube is moved or twisted.
There are two ways to carry out the connection to the
main gas line:
A. The hotplate can be connected with rigid pipe as
specified in AS/NZS 5601.1
B. Flexible Hose: If installing with a hose assembly, install
with a hose assembly that complies with AS/NZS 1869
(AGA Approved), 10 mm ID, class Bor D, no more than
1,2 m long and in accordance with AS/NZS 5601.1.
Ensure that the hose does not contact the hot surfaces of
the hotplate, oven, dishwasher or any other appliance
that may be installed underneath or next to the hotplate.
The hose should not be subjected to abrasion, kinking or
permanent deformation and should be able to be
inspected along its entire length with the cooktop in the
installed position. Unions compatible with the hose
fittings must be used and all connections tested for gas
leaks.
The supply connection point shall be accessible with the
appliance installed.
Fig. 5 Fig. 6

14
WARNING: Ensure that the hose assembly is restrained
from accidental contact with the flue outlet of an
underbench oven.
Before Leaving- Check all connections for gas leaks with
soap and water. DO NOT use a naked flame for detecting
leaks. Ignite all burners both individually and concurrently
to ensure correct operation of gas valves, burners and
ignition. Turn gas taps to low flame position and observe
stability of the flame for each burner individually and all
together. Adhere the duplicate data plate to an
accessible location near the hotplate. When satisfied with
the hotplate, please instruct the user on the correct
method of operation. In case the appliance fails to
operate correctly after all checks have been carried out,
refer to the authorised service provider in your area.
It should be expressly noted that we cannot accept any
liability for direct or indirect damage caused by wrong
connection, leakage or improper installation. When being
repaired, the appliance must always be disconnected
from the mains supply; if required, notify our customer
service.
