Chimney must be dimensioned in a correct
way according to the type of cooker it is con-
nected with, minding the environmental and
general conditions of the place in which it is
placed. The section of the chimney must per-
mit the flow of the fumes produced by the
cooker without difficulties, but it must not
be too big otherwise the chimney will experi-
ence problems in heating itself and this may
generate problems like weak draught and
condensation. In the table it is indicated the
recommended diameter for the flue accord- ing to the model of cooker and to the height
of the chimney (H). The height of the chim-
ney 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 is not insured.
The chimney must not have tortuous parts,
horizontal parts or counterslope parts; the
number of bends must be reduced to mini-
mum. In picture 4 you can see some examples
of good and bad chimney connection.
