Figure 3a): Tubing from exterior: the recommended solution for connecting the wood
burner to the chimney of the building. Tubing from interior: recommended when the height of
the chimney exceed 6m in height. (In the chimney of the building normally the first
metre of tubing is used for connecting the chimney of the building, then continuing
just with this. In this first metre of tubing generally the pull is good and no
condensation is produced).
Figure 3b): Solution recommended when there is the risk of excessive cooling of the
smoke in the chimney, with the possible formation of condensation.
metal chimneys, the smoke can cool and produce condensation, to prevent this,
chimneys with a wider diameter are used which facilitate the outlet of smoke).
5. - Some regulations
Below we provide some rules which must be followed when building the chimney:
a) Use resistant and fireproof materials. Do not install fibre cement tubing.
b) Choose the most vertical route possible. Do not connect several appliances
to the same chimney.
c) Prevent the duct letting out in areas near to buildings. It must exceed the
nearest rooftop in height, if there is an adjacent building.
