Exhaust ducting
If the extractor is used at the
same time as a heating appliance
that relies on oxygen from the same
room, there is a risk of toxic fumes.
It is essential that the “Warning and
Safety instructions” are observed.
The extractor should be installed
according to local and national
building regulations. Seek approval
from the building inspector where
necessary.
The extractor has an exhaust
connection of 222x89mm.
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 cross-section of the exhaust
ducting must not be smaller than the
cross-section of the exhaust
connection (see “Appliance
dimensions”).
- 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.
- Ensure that all connections are
strong and airtight.
Remember that any constriction of
the airflow will reduce extraction
performance and increase operating
noise.
