Venting
The hood is more effective when used in the
extraction mode (ducted to the outside).
Venting kits may be purchased through your
retailer or DIY store, and must be ducted to an
outside vent of 125mm (5").
The 120÷125mm collar should be fitted onto the
ducting spigot to suit UK diameter ducting, and
held in position by a jubilee clip (not supplied)
used to secure the flexible hose.
Where flexible duting is fitted the length should be
no more than:
3 metres with one 90º bend, or
2metres with two 90º bends.
Bends of more than 90º will reduce the efficency
of the hood and reduce airflow.
The ducting used must be manufactured
from fire retardent material conforming to
the relevant British Standard or DIN 4102-
B1.
When the cooker hood is ducted to the outside the
charcoal filters must be removed.
Recirculation
If you are using the hood for recirculation, ensure
the charcoal filters are in position following the
instructions contained in the section "To Remove/
Replace the Charcoal Filters".
Note: When the hood is used in the
recirculation mode ensure that the
plate (T) has been fixed into the lower
chimney section. If not, fit the plate as
illustrated opposite using two of the
self tapping screws provided in the
fixing kit.
