User manual

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

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

, 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 as an extractor,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 (100 or 120 mm Ø min.).

Failure to observe these basic rules will drastically reduce the

performance and increase the noise levels of the extractor hood.

Where flexible ducting is fitted 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 air flow.

Electrical connections

Please ensure that the voltage and current indicated on the rating

plate agree with the voltage of your electricity supply.

If your appliance has been equipped with a mains lead with a

moulded-on type plug, you must comply with the following
