Miele SmartLine CSDA 7000 FL Operating And Installation Instructions page 51

 If the exhaust air is to be ducted into
a flue, the ducting must be directed in
the flow direction of the flue.
 If ducting is to be laid horizontally, it
must be laid with a downwards
sloping gradient. This is to ensure
that condensate cannot drain back
into the extractor.
 If the vent ducting is to run through
rooms, ceiling space, etc. there may
be great variations in temperature
between the different areas. The
problem of condensation will need to
be addressed. The exhaust ducting
will need to be suitably insulated.
 Ensure that the ducting can easily be
disconnected from the exhaust
connection in the event the appliance
needs to be taken out of the worktop
for service purposes.
 Stick the supplied sealing strip on the
exhaust connection if the ducting
does not sit securely up against the
exhaust connection.
