2.11 Hob fan installation

• The product may only be connected by a qualifi ed fi tter
according to applicable local regulations. The same
applies for the extraction air connections. The fi tter is
responsible for proper functioning at the installation
site.
• On installation, observe the relevant national building
regulations and the regulations of the electricity sup-
pliers.
• The hob fan can be operated in the extraction air and
recirculation air mode.
• Lead the outgoing air outside through a ventilation shaft
intended for this purpose or through the wall of the
building.
• Outgoing air may not be led into a smoke or exhaust
gas fl ue which is in operation. Contact the district mas-
ter chimney sweep if you are in any doubt.
• A suffi cient supply of inlet air must be provided if a
wood, coal, gas or oil heater requiring a chimney is
operated in the environment of the hob fan, since an
insuffi cient supply of air results in a risk of poisoning.
The safe operation of the hob fan is guaranteed when
the negative pressure resulting from the hob fan does
not exceed 0.04 mbar (4 Pa) and a suffi cient supply of
inlet air can fl ow into the room.
• Exhaust air pipes must comply with fi re class B 1 DIN
4102.
• Please make sure that the minimum nominal width of
the appliance connecting pieces is not reduced.
• A system recommended for the airfl ow and compatible
with the hob extractor should always be used.
• The nominal width of the recirculation air pipe should
not be less than 150 mm.
• Exhaust air pipes should be as short as possible. They
should not have a 90-degree angle; instead they should
have soft bends and no reductions in their cross-secti-
on.
• Never use pipes with a diameter of less than 150 mm.
No bends/angles may be laid 50 cm before the fan
module.
• Always insert a straight piece of approx. 50 cm bet-
ween two angles/bends.
• The cross-section of wall vents and the cut-out in the
base panel should should at least correspond to the
exhaust air pipe. The outfl ow opening must be at least
500 cm². Reduce the height of the skirting boards or
make corresponding openings.
• When installing the appliance make sure that the con-
vection air unit is still accessible when the kitchen has
been completely installed.
• If necessary levelling feet for the kitchen units must be
moved.
PLEASE NOTE
When the convection air mode is in
operation, ventilation must be suffi cient in
order for the air humidity to be removed.
