Assembly and instal-
lation
Safety instructions
• This appliance must be installed in accordance with the ruling regulations
and may only be used in well ventilated rooms. Please read the instructions
before installing and commissioning the appliance.
• Attention! The gas category permitted for the connection of the appliances
can differ from region to region. In case of doubt enquire at your local gas
board to find out which categories of gas come into question.
• Before connecting the appliance it must be checked whether the local sup-
ply conditions (type of gas and gas pressure) and the settings of the ap-
pliance correspond. If there are any discrepancies the appliance must be
converted accordingly!
• The settings for this appliance are indicated on an indicating label (or on
the identification plate). The settings can also be found in these instructions
in the section „Technical data“ (page 25).
• If the appliance is connected up to the gas mains, particular attention must
be paid to the relevant regulations and guidelines laid down by the associa-
tions in the country where the appliance is being operated.
• Regulations of the local gas utilities and authorities (e.g. for fire protection)
are also to be observed.
• Statutory regulations and the connection specifications issued by the local
power supply company must be strictly observed.
• The appliance should only be connected and put into operation by a quali-
fied gas fitter who should also be the only person to carry out any work
such as maintenance and repair or adjustment and conversion. The legally
recognised regulations and the conditions for connection laid down by the
local gas board should be observed in all details.
Work which has been improperly carried out endangers the safety of the
user!
• This appliance should not be connected to a pipe for extracting combustion
products. It must be installed and connected in accordance with the appli-
cable conditions of installation.
Particular attention should be paid to sufficient ventilation measures.
• If the connection plug should not be accessible, protect the appliance by
line-protecting switches, fuses or contactors whose contact opening has a
width of at least 3 mm.
• When the appliance is being connected up and when repair work is being
carried out on it, the appliance should be disconnected from the electricity
supply using one of these devices. Always ensure to disconnect the ap-
pliance from the energy supply when repairs are being carried out on faci-
lities for directing the flow of gas.
• If the power supply cable of this device is damaged, it must be replaced by
a special supply cable available from the manufacturer directly or the cu-
stomer service.
• The earth wire must be sufficiently long so that if the strain relief fails, the
live wires ofthe connecting cable are subjected to tension before the earth
wire.
• When converting from natural gas to liquefied petroleum gas, it is always
necessary to change the injectors of the wok burner. This also applies if the
reverse is the case. This conversion should only be carried out by a qualified
gas fitter.
• No changes may be made to the appliance unless with the express appro-
val of the manufacturer.
• When the appliance has been built in it should not be possible to come into
contact with parts that are under electric current.
Conditions for building in the appliance
The installation space must have a minimum volume of 20 m³, and must have
a window or door to the outside for ventilation purposes.
The hob is built into a worktop opening, which must be cut in accordance with
the dimensions specified below.
The side clearance between the hob and wall units must be at least 60 mm.
However, for practical reasons, a clearance of at least approx. 300 mm should
be ensured.
The wall connection strip should be made of heat-resistant material and must
not be provided with sockets in the area around the hob. We recommend using
a support strip made of plastic and a covering strip made of aluminium. The
lateral part on the worktop must not be longer than 30 mm.
The wall above the wall connection strip in the area around the appliance must
be made of non-inflammable material. Wood, plastic, PVC foil etc. do not meet
this requirement.
Under normal operating conditions heat with a temperature of 65 °C above
room temperature can radiate onto the surrounding furniture. The furniture
parts must at least conform to this requirement.
The plastic finish or the veneer of built-in kitchen furniture must have been pro-
duced using a heat-resistant adhesive (100 °C).
Minimum distance to adjacent wall cupboards hung high above the oven is
650 mm. Please take note of the instructions of the respective manufacturer of
the cooker hood.
The underside of the properly installed hob must be protected by a cover (inter-
mediate bottom or liner) to prevent any accidental contact with the underside
of the the hob.
It must only be possible to remove this cover with tools.
Gas connection
When the appliance is fitted and installed, particular attention must be paid to
the relevant regulations and guidelines.
First check whether you have the right type of gas and the right gas supply pres-
sure. You will find the details of the gas supply pressure under the heading
“Technical data”.
The stick-on label indicates what type of gas the built-in hob has been set to run
on.
It is possible to convert to another type of gas; this is explained in these opera-
ting and installation instructions under “Converting to a different type of gas”.
The gas connection must only be done by an approved and qualified gas
fitter!
The gas connection at a customer is preferably to be carried out so that it is
easily accessible in an adjacent side cabinet.
It must be ensured that the connection parts are laid in such a way that they
cannot heat up and become damaged while the appliance is in operation and
that they cannot come into contact with the movable parts of the kitchen ele-
ments.
Leave the main gas cock closed initially and do not insert the plug into
the socket yet.
Electrical connection
An earthed shockproof socket is required for electrical connection. The electri-
cal connection must be carried out in compliance with VDE guidelines and
should preferably be in an adjacent cabinet. The appliance has been designed
for a mains supply of 230 V/50 Hz. For details of electrical power input, please
refer to the Technical Data on page 25.
The connection cables must be laid in such a way that they do not heat up and
become damaged when the appliance is in operation.
