AEG 8820, Operating And Installation Instructions

63

• 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 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 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 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.

— 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.
