2.4 Supply of combustion air
All wood burning stoves need constant supply of air to ensure a clean and efficient combustion. This is often
a problem in modern energy-efficient houses that are very tight. Therefore, the Aduro 9 air is equipped with
external supply of combustion air, where the air to the combustion is supplied from the outside and directly
into the wood burning stove. Air from the outside can be provided through a channel, which is connected to
the connecting pipe under the combustion chamber. The amount of air needed for combustion is 25m3/h.
The connecting pipe has an external diameter of 78 mm, to which you need a pipe with a diameter of 80 mm.
If the pipe work is further than 1 m, the pipe diameter must be increased to 100 mm and a correspondingly
larger wall valve must be chosen. In warm rooms the channel should be insulated with 30 mm mineral wool
covered with a damp-proof course (plastic). It is important that the lead-in between the pipe and the wall (or
floor) is sealed with jointing compound. You can eventually use the complete Aduro fresh air kit.
The pipe with external supply of combustion air can be taken out at the bottom of the back side of the stove
or under the stove (see illustration below):
If you want to use the wood burning stove without connecting the supply of combustion air, “brake” off the
cover plate in the rear cover at the bottom of the back of the stove.
