Miele Imperial DA 846-1 Operating And Installation Manual page 9

When using the cooker hood at the
same time as another heating ap-
pliance which depends on the air in the
room, (e.g. gas, oil or coal fired
heaters, continuous flow or other water
heaters, gas cooker, gas hob or gas
oven) special care must be taken, as
the action of the cooker hood extracts
air from the room, which these types of
heater need for combustion.
In order to ensure safe operation, and
to prevent the gases given off by the
heating appliances from being drawn
back into the room when the extractor
and the heater are in operation simulta-
neously, an underpressure in the room
of 0.04 mbar (4 pa) is the maximum
permissible.
Ventilation can be maintained by air in-
lets which cannot be blocked, in win-
dows, doors and outside wall vents, or
by other technical measures, such as
ensuring that the extractor can only be
switched on when the heating ap-
pliance is switched off or vice-versa.
N.B.: The overall ventilation condition of
the dwelling must be taken into ac-
count.
If in any doubt, the advice of a compe-
tent builder or, for gas, a "Corgi" instal-
ler must be sought.
In countries which may be subject
to infestation by cockroaches or
other vermin, pay particular attention to
keeping the appliance and its surround-
ings in a clean condition at all times.
Any damage which might be caused
by cockroaches or other vermin will not
be covered by the appliance guaran-
tee.
Before discarding an old ap-
pliance switch off and disconnect
from the power supply. Cut off and ren-
der any plug useless. Cut off the cable
directly behind the appliance to pre-
vent misuse. This should be done by a
competent person.
The manufacturer cannot be held re-
sponsible for any damage caused
by non-observance of these instruc-
tions.
