Exhaust ducting
Before installation, it is important
to read the following information.
This is particularly crucial when using
the downdraft extractor at the same
time as a heating appliance that
relies on oxygen from the same
room, which could result in the build-
up of toxic fumes.
It is particularly important that the
“Warning and Safety instructions”
are observed.
The downdraft extractor should be
installed according to local and
national building regulations. Seek
approval from the building inspector
where necessary.
The downdraft extractor has an exhaust
connection of 222x89mm.
In order to achieve optimum
extraction or recirculation
performance and low noise levels,
Miele recommends the installation of
a modular rectangular ducting system
made from approved non-flammable
materials.
To achieve the most efficient air
extraction with the lowest noise
levels, please note the following:
- The cross-section of the exhaust
ducting must not be smaller than the
cross-section of the exhaust
connection (see the appliance
dimensions).
- The exhaust ducting should be as
short and straight as possible.
- For the rectangular ducting, Miele
recommends not to exceed a
maximum total ducting length of 5 m,
with a maximum number of three
bends.
- Only use wide radius bends.
- The exhaust ducting must not be
kinked or compressed.
- Ensure that all connections are
strong and airtight.
Remember that any constriction of
the airflow will reduce extraction
performance and increase operating
noise.
