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 ~ Page 19
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
A = straight piece (1.0 m)
B = curved pipe (R = 200 mm)
C = straight piece (1.5 m)
D = pipe elbow
E = telescopic wall box with grid 14

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
A = curved pipe (R = 300 mm)
B = straight piece (1.5 m)
C = curved pipe (R = 100 mm)
D = straight piece (0.5 m)

– It is not permitted to connect the
– If the appliance is being
exhaust air duct to chimneys
which are connected to gas or
coal-fired ovens/cookers or gas-
fired heating systems.
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.
