Ducting
If the downdraft extractor is used
at the same time as a heating appli-
ance 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 downdraft extractor should be
installed according to local and na-
tional building regulations. Seek ap-
proval from the building inspector
where necessary.
The downdraft extractor has an exhaust
connection of 222x89mm.
Only use smooth pipes or flexible ex-
haust hoses made from non-flam-
mable materials for exhaust ducting.
To achieve the most efficient air
throughput with the lowest noise
levels, please note the following:
- The cross-section of the ducting
must not be smaller than the cross-
section of the exhaust duct connec-
tion (see “Appliance dimensions”).
- The 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 air flow will reduce air throughput
and increase operating noise.
If the exhaust air is to be ducted into
a flue, the ducting must be directed in
the flow direction of the flue.
If ducting is to be laid horizontally it
must be laid with a downwards slop-
ing gradient. This is to ensure that
condensate cannot drain back into
the fan.
If the ducting is to run through rooms,
ceiling space, etc. there may be great
variations in temperature between the
different areas. The problem of con-
densation will need to be addressed.
The ducting will need to be suitably
insulated.
