Installation
Connection for air extraction
Only use smooth pipes or flexible
ducting made from approved non-
flammable materials for exhaust
ducting.
To achieve the most efficient air
extraction with the lowest noise levels,
please note the following:
- The diameter of the exhaust ducting
must not be smaller than the cross-
section of the exhaust connection
(see "Appliance dimensions"). This is
particularly applicable when using flat
ducting.
- The exhaust ducting must be as
short and straight as possible.
- Only use wide radius bends.
- The exhaust ducting must not be
kinked or compressed.
- All connections must be strong and
airtight.
- If the ducting has flaps, these must
be opened when the rangehood is
switched on.
Any constriction of the airflow will
reduce extraction performance and
increase operating noise.

Vent flue
If the exhaust air is to be ducted into a
vent flue, the ducting must be directed
in the flow direction of the flue.
If the flue is used by several ventilation
units, the cross-section of the flue must
be large enough.
Non-return flap
Make sure you use a non-return flap
in the exhaust air system.
A non-return flap ensures that when the
rangehood is not in operation, the duct
is closed and no exchange of room and
outside air can take place.
If the exhaust air is ducted through an
outside wall, a Miele wall vent or a
Miele roof vent (available as an optional
accessory) is recommended. These are
fitted with an integrated non-return flap.
Miele will not accept warranty claims
for any functional defects or damage
caused by inadequate ducting.
