When the unit is used in its extractor version, a sufficiently large

ventilation hole must be provided, with dimensions that are approxi-

mately the same as the outlet hole.

National and regional building regulations impose a number of

restrictions on using hoods and fuel-burning appliances connected

to a chimney, such as coal or oil room-heaters and gas fires, in the

same room.

Hoods can only be used safely with appliances connected to a

chimney if the room and/or flat (air/environment combination) is

ventilated from outside using a suitable ventilation hole approxi-

mately 500-600 cm

being created during operation of the hood.

If you have any doubts, contact the relevant controlling authority or

building inspectors office.

Since the rule for rooms with fuel burning appliances is outlet hole

of the same size as the ventilation hole, a hole of 500-600 cm

which is to say a larger hole, could reduce the performance of the

extractor hood.

If the hood is used in its filtering function, it will operate simply and

safely in the above conditions without the need for any of the

aforementioned measures.

When the hood is used in its extractor function, the following rules

must be followed to obtain optimal operation:

short and straight outlet hose

keep bends in outlet hose to a minimum

never install the hoses with an acute angle, they must always

follow a gentle curve.

keep the hose as large as possible (preferably the same diam-

eter as the outlet hole).

the length should be no more than:

3 metres with one 90° bend

2 metres with two 90° bends

Bends of more than 90° will reduce the efficiency of the hood

and reduce the airflow.

Failure to observe these basic instructions will drastically reduce the

performance and increase the noise levels of the extractor hood.
