Exhaust 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. 2.
• 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. 1.
The table below shows the exhaust duct
diameter and the necessary fresh-air
inlet area.
• The exhaust duct must have a nonreturn flap
after each dryer.
Note! It is recommended that each dryer is
connected to a separate exhaust duct.
