Miele DA5341D - Manual (Page 7)

The ventilation hood works by air
extraction. The air is drawn in and
cleaned by the grease filter and
directed outside.
The hood comes equipped with a
non-return flap in each chimney. This
flap automatically closes when the
hood is turned off so that no exchange
of outside air and room air can occur.
When the hood is turned on, the air
pressure of the exhaust fan
automatically opens the flap blowing
the inside air and cooking odors
outside.
