Chimney has a main importance for the correct
working of every wood burning device. The stove
works at its best only if the chimney matches the
building laws. Call an experienced technician or a
2.3
DIMENSIONS AND CORRECT FORMS OF CHIMNEY
Chimney must be dimensioned in a correct way ac-
cording 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 pro-
duced by the stove without difficulties, but it must
not be too big otherwise the chimney will experi-
ence problems in heating itself and this may gener-
ate problems like weak draught and condensation.
In table 1 it is indicated the recommended diameter

for the flue according to the height of the chimney.
The height of the chimney must be enough to in-
sure the draught necessary. 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 4 you can see some examples
of good and bad chimney connection.
