Miele DA5000D - Manual (Page 29)

If the exhaust is ducted into an inactive
flue, the air must be expelled parallel to
the flow direction of the flue.
Never connect an exhaust hood to
an active chimney, dryer vent, flue,
or room venting ductwork. Seek
professional advice before
connecting an exhaust hood vent to
an existing, inactive chimney or vent
flue.
Important
If the duct work runs through rooms,
ceilings, garages, etc. where
temperature variations exist, it may
need to be insulated to reduce
condensation.
