The lower edge of the stove must be minimum 22.5 cm above the floor.
2.5 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 wood burning stove is
equipped with external supply of combustion air, where the air to the combustion can be provided through a
channel from the outside and directly into the wood burning stove. The amount of air needed for combustion
is 25 m3/h. Air vents must be positioned where they cannot be blocked.
The connecting pipe for the external air supply has an external diameter of 78 mm, to which you need a pipe
with a diameter of 80 mm. If the pipe work is more than 100 cm, or if there are bends on the tube, the
resistance in the pipe increases significantly. Negative pressure outside on the sheltered side of the house
can also affect the resistance of the pipe. In these situations, the pipe should have a diameter of minimum
100 mm. It may also require a stronger chimney draft, which you can achieve by installing an Aduro
DraftOptimizer.
You can easily test the resistance in the pipe by opening a window close to the stove, disconnect the
external air supply and then light up the stove. If the combustion looks different than before, there is too
much resistance in the external air supply. If the pipe work is longer 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. If necessary, you can
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):
