Installation instructions

Prior to installation, always follow the
instructions and warnings in the chapter
entitled "Safety instructions"!
Exhaust-air mode
The exhaust air is conveyed upwards via a
ventilation shaft or directly through the outer
wall to the exterior.
Note: The exhaust air must not be conveyed into a
functioning smoke or exhaust gas flue or into a
shaft which is used to ventilate
installation rooms which contain heating
appliances.
Before conveying the exhaust air into a non-
functioning smoke or exhaust gas flue, obtain
the consent of the appropriate heating
engineer.
Discharge exhaust air in accordance with the
official and statutory regulations (e.g. regional
building laws).
If the exhaust air is conveyed through the outer
wall, a telescopic wall box should be used.
To ensure optimum performance, the extractor
hood requires:
a short, straight exhaust air pipe and
the largest possible pipe diameter.
If pipe bends cannot be avoided, ensure the
largest possible radii.
Note: If long, rough exhaust air pipes, a lot of pipe
bends or pipe diameters less than 150 mm are
used, the air capacity will be less than optimum and
there will be an increase in noise.
Use only pipes or hoses made of non-
combustible material for installation of the
exhaust air duct.
The manufacturer of the extractor hoods is not
responsible for complaints which can be
attributed to planning and design of the
pipework.

Connecting pipes

The diameter of the exhaust air pipes should
not be less than 150 mm.
Round pipes:
We recommend an inner diameter of 150 mm,
however at least 120 mm.
Flat ducts must have the same inner cross-
section as round pipes.
There should be no sharp bends.
Ø 150 mm approx. 177 cm
Ø 120 mm approx. 113 cm
If pipe diameters differ:
Use sealing strips.
Connection of 150 mm ø exhaust air pipe
(recommended size)
Attach exhaust air pipe
directly to the air-pipe
connector and seal
appropriately. If using an
aluminium pipe, smooth the
connection area beforehand.
Connection of 120 mm ø exhaust air pipe
Attach reducing connector
directly to the air-pipe
connector.
Attach exhaust air pipe to the
reducing connector.
Seal both joints appropriately.
