Connection For Air Extraction - Miele PUR 68 W Operating And Installation Instructions

Connection for air extraction


Before installation, it is important
to read the information given on the
following pages as well as the
"Appliance dimensions" and the
"Warning and Safety instructions" at
the beginning of this booklet. This is
particularly crucial when using the
rangehood 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.
The rangehood should be installed
according to local and national
building regulations. Seek approval
from the building inspector where
necessary.
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.
