3.3 Requirements for the wall duct:
D WARNING!
Risk of death due to improper installation!
A wall break-through influences the structural integrity of the
building. There is a danger of collapse. This work must only
be carried out by a specialist.
☞
Make sure that the wall duct is established properly.
D ATTENTION!
Danger of property damage due to improper installation!
If the angle of the wall duct is incorrect, water can flow inside
and cause damage.
☞
Make sure that the wall duct is angled 1-2° outwards.

3.4 Requirements for the exhaust air duct
D WARNING!
Fire hazard and asphyxiation hazard due to improper
installation!
When using the exhaust air ducting with other devices
or when connecting an active exhaust air channel (e.g.
chimney), gases or smoke can be drawn into the room.
☞
Make sure that the requirements for the exhaust air
ducting are complied with.
y The exhaust air ducting is used exclusively by this device.
y The exhaust air ducting is made of non-combustible
material in accordance with DIN 4102 class 1.
y When routing the exhaust air ducting through the
outside wall:
y The cross-section must not be smaller than that of the
fan outlet.
y Installation of condensed water collector in the
exhaust air ducting in order to prevent water damage
inside the device. The condensed water collector must
be adequately dimensioned.
y Adequate fresh air supply is assured through the
installation of the necessary accessories (e. g. window
contact switch).
The cross-section, length, type and course of the exhaust
pipe affect the extraction efficiency. Changing the direction
of the air too severely leads to a loss of performance and to
noise.
To optimise the device performance:
y Keep the exhaust air ducting as short as possible and
route it directly to the outside.
y The stipulated cross-section of the exhaust air ducting is
complied with.
y Exclusive use of ducts and bends with smooth inner
surfaces.
In order to avoid turbulence or backpressure in the
transported air - do not use:
y Spiral hoses.
y Flexible tubes.
y Flat deflection pieces.
y Sharp-edged exhaust air channels.
