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.
