Evacuation system
Exhaust duct
It applies to the exhaust duct that:
• The exhaust duct must be smooth on the inside
(low air resistance).
• The exhaust duct must lead into the open.
• The exhaust duct must lead clear of the
building as condensation may cause frost
damage to the building.
• The exhaust duct must be protected against
rain and foreign objects.
• The exhaust duct must have gentle bends,
fig. 1.
• The exhaust duct must not be a shared duct
between dryers and appliances using gas or
other fuels as their energy source.
It applies to the installation of several dryers
on a shared exhaust duct that:
• The exhaust duct diameter must increase after
each dryer, fig. 2.
The table below shows the exhaust duct
diameter and the necessary fresh-air inlet area.
Note!
It is recommended that each dryer is
connected to a separate exhaust duct.
Service organization/dealer
If you have questions relating to the design of the
exhaust system, please contact your local dealer
or service organization.
The exhaust duct
diameter must not
be reduced.
