Connection for air extraction

Important: To avoid the danger of

toxic fumes, please observe the

Warning and Safety instructions.

This is especially crucial when using

the cooker hood at the same time as

another heating appliance which

relies on air from the same room.

The cooker hood should be installed

according to local building

regulations. Seek approval from the

building inspector where necessary.

– Only use smooth pipes or flexible

hoses made from non-flammable

materials for the extraction ducting.

– When using an external motor, make

sure that the exhaust ducting is

sufficiently rigid. The external motor

can cause an underpressure which

could result in the exhaust ducting

distorting.

To achieve the greatest possible air

extraction with the lowest noise level,

please note the following:

– To ensure efficient air extraction, the

diameter of the exhaust ducting

should not be less than 150 mm.

– If flat ducting is being used, the

cross-sectional area must not be

smaller than the cross-sectional area

of the exhaust connection.

– All ducting, pipework and fittings

must be of non-flammable materials.

– The exhaust ducting should be as

short and straight as possible.

– Only use wide radius bends.

– The exhaust ducting should not be

kinked or compressed.

– Ensure that all connections are

strong and airtight.

– Where ducting is horizontal, it must

be laid to slope away by at least

1 cm per metre. This is to ensure that

condensate cannot drain back into

the cooker hood.
