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 of
0.04 mbar (4 pa) is the maximum
permissible in the room.
Ventilation can be maintained by air
inlets which must not be blocked, in
windows, doors and 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 (Corgi registered
in the UK) must be sought.
Warning and Safety instructions
If the only way of ensuring adequate
ventilation is via an open window, then
a window contact switch should be
fitted.
The window contact switch ensures that
the cooker hood can only operate when
the window is opened sufficiently. The
cooker hood simply needs a conversion
kit to operate via the window contact
switch. The conversion kit is available
from the Miele Spare Parts Department.
Take care when ventilating the room
through an open window that ventilation
is not impaired by a closed blind or
curtain.
If the hood is being operated in
recirculation mode, the above
restrictions do not apply.
If in any doubt, the advice of a
qualified builder, gas fitter (Corgi
registered in the UK) or electrician
must be sought.
