Important: To avoid the danger of

toxic fumes, please observe the

Warning and Safety instructions.

This is especially crucial when using

the rangehood at the same time as

another heating appliance which

relies on air from the same room.

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

hoses made from non-flammable

materials for extraction connection.

–

When using an external motor, make

sure that the extraction 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

diameter must not be smaller than

the diameter of the exhaust

connection.

– If exhaust ducting with a diameter of

less than 150 mm, or if flat ducting is

used, the noise level of the

rangehood will increase and

extraction will be less efficient.

–

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 at at least 1 cm

per metre. This is to ensure that

condensate cannot drain back into

the rangehood.
