13.7 Instructions for the exhaust air pipe
The appliance manufacturer does not provide any war-
ranty for faults attributable to the pipeline.
¡ Use a short, straight exhaust air pipe with as large a
pipe diameter as possible.
¡ Long, rough exhaust air pipes, many pipe bends or
small pipe diameters reduce the suction power and
increase the fan noise.
¡ Use an exhaust air pipe that is made of non-com-
bustible material.
¡ To prevent condensate from returning, fit the ex-
haust pipe with a 1° gradient from the appliance.
Flat ducts
Use flat ducts with an inner cross-section that corres-
ponds to the diameter of the round pipes:
¡ Diameter of 150 mm corresponds to ap-
prox. 177 cm².
¡ Diameter of 120 mm corresponds to ap-
prox. 113 cm².
¡ Use sealing strips for different pipe diameters.
¡ Do not use any flat ducts with sharp bends.
Round pipes
Use round pipes with an inner diameter of 150 mm (re-
commended) or at least 120 mm.
13.8 Instructions for the air extraction mode
For air extraction mode, a one-way flap should be in-
stalled.
Notes
¡ If a one-way flap is not included with the appliance,
one can be ordered from a specialist retailer.
¡ If the exhaust air is conveyed through the external
wall, a telescopic duct should be used.
13.9 Information about circulating-air mode
The appliance must only be operated when it is se-
curely installed and the pipework is connected.
13.10 General information
Follow these general instructions during the installation.
¡ For the installation, observe the currently valid build-
ing regulations and the regulations of the local elec-
tricity and gas suppliers.
¡ When discharging the exhaust air, the official and
legal regulations, such as the regional building
code., must be observed.
¡ In order to freely access the appliance for servicing,
select an easy-to-reach installation site.
¡ The surfaces of the appliance are sensitive. Avoid
damaging them during installation.
