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 table 1 it is indicated the rec-
ommended diameter for the flue according to the model and to the height of the chim-
ney (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 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.
