Miele DA 337 I - Manual (Page 38)

Never connect an exhaust hood to
an active chimney, dryer vent, vent
flue, or room venting ductwork.
Seek professional advice before
connecting an exhaust hood vent to
an existing, inactive chimney or
vent flue.
Ductwork with a diameter of less
than 6" (150 mm) should only be
used when absolutely necessary.
As duct diameter decreases, the
hood performance and sound levels
will be affected.
Note:
If the ductwork runs through rooms,
ceilings, garages, etc. where tempera-
ture variations exist, it may be necess-
ary to use insulation to reduce conden-
sation. In some cases, a condensate
trap may also be required.
