• When used as an extractor unit, the

hood must be fitted with a hose
having preferably the same diameter
as the outlet hole.

If the instructions for installation for
the gas hob specify a greater
distance, this must be adhered to.

• The national Standard on fuel-

burning systems specifies a maxi-
mum depression of 0.04 mbar in
such rooms.

• The air outlet must not be connected

to chimney flues or combustion gas
ducts. The air outlet must under no
circumstances be connected to
ventilation ducts for rooms in which
fuel-burning appliances are installed.

• The air outlet installation must comply

with the regulations laid down by the
relevant local authorities.

• When the unit is used in extraction

mode, 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 approximately 500-600 cm

large to avoid the possibility of a
depression 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 recirculation

mode, 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

extraction mode, 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 diameter 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.
