Safety warnings

For the installer

• When used as an extractor unit, the hood must

be fitted with a 150mm diameter hose.

Attention: The hose is not supplied and

must be purchased separately.

• When installing the hood observe the

following minimum distances from the

cooking top:

electric cookers

gas cookers

The hood can be installed above these heights

but for optimum performance it should be

installed at the distance quoted for the

appropriate heat source.

• The national Standard on fuel-burning systems

specifies a maximum 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 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

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

is to say a larger hole, could reduce the perfor-

mance 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

500 mm

700 mm

large to avoid the

, which

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.
