The air outlet installation must comply with the regulations laid down

by the relevant authorities.

•

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

ventilation hole must be provided, with dimensions that are

approximately 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 inspector's 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 only

— keep the hose as large as possible (preferably the same diameter

as the outlet hole).

•

Failure to observe these basic instructions will drastically reduce the

performance and increase the noise levels of the extractor hood.
