Hob fan installation
• The product may only be connected by
a qualied tter according to applicable
local regulations. The same applies for
the extraction air connections. The tter is
responsible for proper functioning at the
installation site.
• On installation, observe the relevant national
building regulations and the regulations of
the electricity suppliers.
• 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 ue which is in operation.
Contact the district master chimney sweep if
you are in any doubt.
• A suf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
insufcient supply of air results in a risk of
poisoning. The safe operation of the hob
extractor is guaranteed when the negative
pressure resulting from the hob extractor
does not exceed 0.04 mbar (4 Pa) and a
sufcient supply of inlet air can ow into the
room.
• Exhaust air pipes must comply with 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 air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-section.
• 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 between 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
out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 convection air unit is still accessible
when the kitchen has been completely
installed.
• If necessary levelling feet for the kitchen units
must be moved.
When the convection air mode is
in operation, ventilation must be
sufcient in order for the air humidity
to be removed.
