The appliance must not be connected to a chimney or flue which is in use. Neither should it
be connected to ducting which ventilates rooms with fireplaces. Exhaust ducting must be of
non-inflammable material. If exhaust air is to be extracted into a chimney or ventilation duct no
longer used for other purposes, seek professional advice.
USING AT THE SAME TIME AS OTHER HEATING APPLIANCES THAT DEPEND ON THE
AIR FROM THE ROOM
Warning - danger of toxic fumes
Great care should be taken when using the cooker hood at the same time and in the same room
or area of the house as another heating appliance, which depends on the air in the room. Such
appliances include gas, oil, wood or coal-fired boilers and heaters, continuous flow or other
water heaters, gas hobs, cookers or ovens which draw air in from the room and duct exhaust
gases out through a chimney or extraction ducting.
When used in extraction mode, with or without an external motor fitted, or in recirculation mode
with a recirculation box installed outside the room, the appliance draws air in from the room in
which it is installed and from neighbouring rooms.
If there is insufficient air, an underpressure will occur. The heating appliance will be starved of
oxygen, impairing combustion. Harmful gases could be drawn out of the chimney or extraction
ducting back into the room, with potentially fatal consequences.
In order to ensure safe operation, and to prevent gases given off by the heating appliances from
being drawn back into the room when the cooker hood and the heater are in operation
simultaneously, an underpressure in the room of 0.04 mbar (4 pa) is the maximum permissible.
Ventilation can be maintained by air inlets which cannot be blocked, in windows, doors or
outside wall vents, or by other technical measures, such as ensuring that the cooker hood
can only be switched on when the heating appliance is switched off or vice versa. A ventilation
brick alone is not generally sufficient to ensure safe ventilation.
The overall ventilation condition of the dwelling must be taken into account. If in any doubt, the
advice of a competent builder or, for gas a qualified gas fitter (registered with an official gas
safety body in accordance with national safety regulations, GasSafe in the UK) must be sought.
If the cooker hood is used in recirculation mode, where the air is directed back into the room in
which it is located, operating a heating appliance, which depends on the room air at the same
time, is no cause for concern.
ENERGY RATING
As a result of the new EU65 “Energy label” and EU66 “ Ecodesign” regulations issued by the
European Commission, which came into force as from January 1st, 2015 , our products have
been adapted to comply with these new requirements.
All of the models complying with the energy label requirements, are equipped with new electronics
including a timer device for suction speeds control, when the air capacity exceeds 650m³/h. Internal
motor models, with maximum air capacity higher than 650m³/h, are equipped with a timer device that
automatically switches the suction speed from 4th to 3rd speed, after 5 minutes operation.External
motor models are equipped with remote motors that, as for internal motor versions, include a
timer device that switches down the suction speed when it exceeds 650 m
3
/h. Remote motors,
whose air capacity exceeds 650m³/h at both 4th and 3rd speed, will have the following by default
