Installation option
Notes
■
Route the exhaust air duct in such a
way that the dryer cannot draw the
moist, warm exhaust air back again.
■
The outlet for the exhaust air must
be designed or positioned in such a
way as to prevent any additional
backpressure (e.g. from a direct
ingress of wind) in the escaping
exhaust air, e.g. by using 90°, facing
down
■
The outlet for the exhaust air duct
must be no more than 2.5 m higher
than the exhaust air opening on the
appliance.
Installation options for the exhaust air
duct:
■
Through a wall box into the open
air
Example: pipe connection - inside
diameter = 100 mm, smooth
■
Directly into the open air
Route the exhaust air duct directly
into the open air via an exhaust air
pipe through an open window.
Example: pipe connection - inside
diameter = 100 mm, flexible pipe,
corrugated
■
Through a wall box into chimneys or
ventilation shafts
Notes
– It is not permitted to connect the
exhaust air duct to chimneys
which are connected to gas or
coal-fired ovens/cookers or gas-
fired heating systems.
– If the appliance is being
connected to a moisture-
insulated ventilation shaft the
reponsible chimney sweep must
be informed and the approval of
the local building department
(building supervision office) or
the owner of the building must be
obtained.
