Miele DA 249-4 Service Manual download pdf (Page 8)

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 rangehood

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 rangehood 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 must be sought.

If the rangehood is being operated in

recirculation mode, the above

restrictions do not apply.
