Dear customer,
We would like to thank and congratulate you for your choice.
This practical modern appliance has been made using materials of
the highest quality, which have been put through the strictest of
Quality Controls during manufacture and meticulously tested to
ensure that they meet all of your cooking demands.
We kindly ask you to read and follow these simple instructions
in order to guarantee first-class results from the very start. This
booklet contains important information not only concerning use,
but also concerning your own personal safety and maintenance of
the appliance.
Our products need to be carefully packed to protect them during
transportation. All the material used for packing is considered
essential for this purpose and is also completely recyclable. You
too can contribut towards protecting the environment by disposing
of this material at your nearest recyclable refuse collection point.
Do not dispose of used cooking oil down the kitchen sink. Oil may
seriously damage the environment. Dispose of it in a closed container
at your nearest collection point or, failing this, dispose of it in your
rubbish bin. Although this last solution is far from perfect, your oil
will be taken to a controlled refuse dump where it will not be allowed
to pollute water. You and your children will appreciate it.
Render your old appliance useless before disposing of it at your
nearest recyclable refuse collection centre.
Your local authority will be pleased to inform you where your nearest
centre is.

Electrical:
An electrical 10 amp socket needs to be within 1 m of the
hotplate to allow electrical connection. The socket must remain
accessible after installation of the appliance.
Important note:
Gas:
During the planning stage, consider the position of supply
The hob must be connected to the gas supply with upstream
connection of an isolation valve in accordance with the respec-
tively valid regulations. We recommend that the isolation valve
be fitted prior to the cooktop to enable isolation of cooktop
times.
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.

Direction of gas flow is indicated on the rear of the regulator.
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.
In either of the cases, do not move or twist the L-tube from its
factory-set position.
If for some reason, the L-tube should be twisted, it is necessary
to make sure that this area is properly sealed. Make sure that
all connections performed are free of leakage.
The manufacture does not accept any liability for leakage on
connections performed by the installer or if the L-tube is moved
