en Installation instructions
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 pipe that is made of non-combustible
material.
To prevent condensate from returning, fit the exhaust
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.
