2.3 DIMENSIONS AND CORRECT FORMS OF CHIMNEY
Chimney must be dimensioned in a correct way according to the type of stove
it is connected with, minding the environmental and general conditions of the
place in which it is placed. The section of the chimney must permit the flow of
the fumes produced by the stove without difficulties, but it must not be too big
otherwise the chimney will experience problems in heating itself and this may
generate problems like weak draught and condensation.
In table 1 it is indicated the suggested diameter for the flue according to the
model and to the height of the flue (H).

TS 60
Table 1 – dimension of the flue according to its model and height (H).
The height of the chimney must be enough to insure the draught necessary to the
chosen model. Bigger is the height of the chimney, bigger is the draught; if the
chimney is lower than 4 metres, the correct working of the stove is not insured.
The chimney must not have tortuous parts, horizontal parts or counterslope parts;
the number of bends must be reduced to minimum.
In picture 2 you can see some examples of good and bad chimney connection.
Picture 2 – Samples of correct and incorrect chimney connection.
2.4 FLUE
The flue must be well isolated and circular if possible. The flue must not have
defects, narrowings or losses. All the inspection doors must be closed and well
sealed. The connection of other devices to the same chimney is not allowed.
