and 75cm gives peak efficiency.
• The air must not be discharged into a flue that is used for exhausting
fumes from appliances burning gas or other fuels.
• When the hood is vented externally and used with appliances which
burn fuel (e.g. gas, oil, wood) the area must be sufficiently ventilated to
ensure safe operation. Fresh air must be allowed to freely enter the
room to prevent a partial vacuum.
• A partial vacuum can starve the heating appliance of oxygen, impairing
combustion. It can also prevent toxic fumes from leaving the room, or
can cause fumes to be sucked into the room from outside.
• Safe operation is only possible when the partial vacuum within the
working area does not exceed 4 Pa (0.04 mbar). This can be achieved
by ensuring air is able to enter the room from outside through a suitable
sized opening which cannot be sealed during operation. A number of
alternative solutions are available to ensure this. If in any doubt,
professional advice should be sought.
• Regulations concerning the discharge of air have to be fulfilled.
• There is a potential fire risk if cleaning is not carried out in
accordance with the instructions.
• Clean your appliance periodically by following the method given in the
chapter MAINTENANCE.
• If used in recirculation mode, the charcoal filters trap odours and must
be replaced at least once a year depending on how frequently the
cooker hood has been used.
• For safety reason, please use only the same size of fixing or
mounting screw, which are recommended in this instruction manual.
• Warning: Failure to install the screws or fixing device in accordance
with these instructions may result in electrical hazards
CAUTION:
Accessible parts of the hood can become very hot during
use with cooking appliances, whether in use or not, due to heat
rising from the hob. Sufficient time should be allowed for the unit to
cool before touching either the housing or the grease filters.
