Milan 4 Passive.
The Milan 4 Passive has all the dimensions and characteristics of the Milan
4. It has been developed and tested for "air tight" houses.
When the Milan Passive is installed in accordance with these instructions
and with its dedicated outside air kit, it provides not only primary and
secondary air for combustion it also provides a "curtain of fresh air" into the
stove when the door is opened for up to 3 minutes. This "curtain of fresh
air" prevents harmful C02 entering the room.
