Assembly and installation
Safety instructions
=Take heed of the safety instructions on page 13!
■ Caution! The permissible category for connecting the appliances can vary
from region to region. If you are in any doubt, you should enquire at your
local gas supply company to find out which categories of appliances come
into question. Check whether the details on the identification plate coincide
with the local connection conditions (type of gas and gas pressure) and with
the settings of the appliance. If you ascertain any discrepancies, the
appliance must be converted accordingly!
■ When connecting the appliance to the gas mains you should particularly
observe the relevant regulations and guidelines of the institutions of the
country where the appliance is operated. In Germany and Austria these are:
DVGW-TRGI 1986 Technical guidelines for gas installations (Germany)
TRF 1988/1996 Technical guidelines for liquefied petroleum gas (Germany)
ÖVGW-TRGI and TRG 2, part 1 Technical guidelines (Austria)
You should also observe the regulations of the local gas supply companies
and those stipulated by the authorities (e.g. fire protection regulations).
■ All work such as connection, putting the appliance into operation,
maintenance and repairs or carrying out settings and conversions should
always be done by a qualified gas fitter in conformity with the applicable
safety regulations. The legally binding regulations and connection conditions
of the local gas supply company should be observed in full. Work which is
improperly carried out can represent a potential safety hazard!
■ This appliance is not connected to a pipe for extracting combustion
products. It must be installed and connected according to the applicable
installation conditions. It is particularly important to ensure that adequate
ventilation measures are taken.
■ When the appliance is being connected or repaired it should be dis-
connected from the electricity supply. The energy supply should always be
turned off when repairs are being carried out on facilities that conduct gas.
■ Should the connection plug not be accessible, safeguard measures should
be carried out using line-protecting cutouts, fuses or contactors whose
contact opening has a width of at least 3 mm.
■ The openings to allow the extraction of fumes should not be covered over.
■ When converting from natural gas to liquefied petroleum gas, it is always
necessary to change the injectors of the burner jets. This also applies if the
reverse is the case. Such conversion work should always be carried out by
a qualified gas fitter.
■ Conversion to other types of gas must be clearly and indelibly marked on
the type plate.
■ No modifications should be made to the appliance unless with the explicit
consent of the manufacturer.
Requirements for installation
■ The room where the appliance is installed should have a volume of at least
20 m3 and it must be possible to ventilate it by a window or a door opening
out into the fresh air.
■ The hob is built into an opening in the worktop. This opening must be
prepared according to the installation dimensions specified below.
■ The worktop must be aligned horizontally. Make a clean cut into it for the
opening.
■ There must be no cross bars beneath the opening. They should be cut back
to at least the size of the opening in the worktop.
■ The distances at the front, rear and sides of the hob opening must conform
to the measurements shown in the drawing. The edges at the front and the
rear are based on a worktop depth of 600 mm. The rear edge will be wider
for worktops with a greater depth.
■ We recommend protecting the cut surfaces of the worktop opening with a
coat of waterproof paint.
■ To ensure ease of operation at the hob, tall cupboards at the side should
be at least 300 mm away.
■ Additional space for the gas connection is required below the hob.
■ The wall connection strip must be made of heat-resistant material and must
have no sockets in the area around the hob. We recommend using a
support strip made of plastic with 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. are
not suitable.
■ In normal use very high temperatures may act on the surrounding items of
furniture. The plastic finish or the veneer of built-in kitchen furniture must
be protected by a heat-resistant adhesive (100 °C).
■ Cooker hoods and wall cupboards above the hob must be installed at a mi-
nimum distance of 650 mm.
■ Before installing the hob and any time that the hob is removed, the gasket
should be checked for signs of damage and to ensure that it fits perfectly.
Fit a new gasket if necessary.Do not use any additional adhesives such as
silicone, as there is a danger that plastic-coated worktops could be dama-
ged when the hob is removed.
Exception: Uneven worktops (e.g. worktops with ceramic tiles) require a
gasket made of a heat-resistant, permanently elastic sealing material (e.g.
with silicone, suitable for ceramic surfaces). Only apply this sealing material
around the edge of the hob, never underneath it!
