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, make sure you

observe the following minimum distance

from the top edge of the cooking hob/ring

surfaces:

electric cookers

500 mm

gas cookers

650 mm

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 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

approximately 500-600 cm

2

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

2

,

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.
