Hob fan installation
• The product may only be connected by
a qualified fitter according to applicable
local regulations. The same applies for
the extraction air connections. The fitter 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 flue which is in operation.
Contact the district master chimney sweep if
you are in any doubt.
• A sufficient 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
insufficient 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
sufficient supply of inlet air can flow into the
room.
• Exhaust air pipes must comply with fire 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 airflow 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
outflow 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
sufficient in order for the air humidity
to be removed.
