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 and national

building regulations. Seek approval

from the building inspector where

necessary.

– All ducting, pipework and fittings

must be of non-flammable materials.

– The exhaust 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 150 mm.

If exhaust ducting with a diameter of

less than 150 mm, or if flat ducting is

used, the noise level of the cooker

hood will increase and extraction will

be less efficient.

Only reduce the diameter of the

ducting if absolutely necessary, e.g.

where narrower ducting has already

been installed.

– Only use wide radius bends. Tight

bends reduce the air throughput of

the cooker hood.

– Only use smooth pipes or flexible

hoses made from non-flammable

materials for extraction connection.

– Where ducting is horizontal, it must

be laid to slope away at at least 1 cm

per metre.

This is to ensure that condensate

cannot drain back into the cooker

hood.

– If the exhaust air is to be ducted into

the open air, the installation of a

telescopic wall vent is recommended.

– If the exhaust air is to be ducted into

a vent flue, the ducting must be

directed in the flow direction of the

flue.
