7.10 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 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 corre-
sponding 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 operati-
on, ventilation must be suffi cient in order for
the air humidity to be removed.
