Connection for air extraction



Before installation, it is important

to read the information given on the

following pages as well as the

"Appliance dimensions" and the

"Warning and Safety instructions" at

the beginning of this booklet. This is

particularly crucial when using the

rangehood at the same time as a

heating appliance that relies on

oxygen from the same room, which

could result in the build-up of toxic

fumes.

The rangehood should be installed

according to local and national

building regulations. Seek approval

from the building inspector where

necessary.

Only use smooth pipes or flexible

ducting made from approved non-

flammable materials for exhaust

ducting.

When using an external motor, make

sure that the exhaust ducting is

sufficiently rigid. The external motor

can cause an underpressure which

can result in the exhaust ducting

distorting.

To achieve the greatest possible air

extraction with the lowest noise level,

please note the following:

– 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.

– The exhaust ducting should be as

short and straight as possible.

– Only use wide radius bends.

– The exhaust ducting must not be

kinked or compressed.

– Ensure that all connections are

strong and airtight.

Remember that any constriction of

the airflow will reduce extraction

performance and increase operating

noise.

 If the exhaust is ducted through an

outside wall, a telescopic wall vent or

a roof vent (available as an optional

accessory) 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.

 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 rangehood.

 If the exhaust ducting is to run

through rooms, ceiling space etc.

there may be great variations in

temperature between the different

areas. The problem of condensation

will need to be addressed. The

exhaust ducting will need to be

suitably insulated.
