Connection for air extraction

Danger of toxic fumes.

Please heed the "Warning and

Safety instructions" to avoid the

danger of toxic fumes.

The cooker hood should be in-

stalled according to local building

regulations. Seek approval from the

building inspector where necessary.

Connection for air extraction

– All ducting, pipework and fittings must

be of non-flammable material.

– The extraction ducting should be as

short and straight as possible.

– To ensure efficient air extraction the

diameter of the exhaust ducting

should not be less than 125 mm.

The use of flat ducting also reduces

the air extraction efficiency.

The use of extraction ducting with a

diameter of less than 125 mm and of

flat ducting increases the noise level

of the cooker hood.

– Only use wide radius bends. Tight

bends reduce the air throughput of

the cooker hood.

– Only use smooth or flexible pipes

made from non-flammable materials

for extraction connection.

– When ducting is horizontal it must be

laid to slope away at 1 cm per metre,

to ensure no condensate drains into

the appliance.

– If the exhaust air is to be ducted into

the open air the installation of a tele-

scopic wall vent is recommended.

– If the exhaust air is to be ducted into

a vent flue the ducting must be di-

rected in the flow direction of the flue.
