Chimney must be dimensioned in a correct way ac­
cording to the type of device 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 cooker or thermal cooker without dif­
ficulties, 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 rec­
ommended diameter for the flue according to the

cular if possible. The flue must not have defects,
narrowings or losses. All the inspection doors must
model of device and to the height of the chimney
(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 cooker or thermal cooker 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 6 you can see some examples of good and
bad chimney connection.
