Connection for air extraction
If the cooker hood is used at the
same time as a heating appliance
that relies on oxygen from the same
room, there is a risk in certain
circumstances of toxic fumes
building up.
It is essential that the “Warning and
Safety” instructions are observed.
The cooker hood should be installed
according to local and national
building regulations. Seek approval
from the building inspector where
necessary.
Only use smooth pipes or flexible
exhaust ducting made from
approved non-flammable materials
for exhaust ducting.
To achieve the most efficient air
throughput 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 duct (see
“Appliance dimensions”). This applies
in particular when using flat ducting.
- The exhaust ducting should 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 exhaust ducting has flaps,
these must be opened whenever the
cooker hood is switched on.
Any constriction of the air throughput
will reduce extraction performance
and increase operating noise.
Flue
If the exhaust air is to be ducted into a
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.
