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 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 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 5 you can
see some examples of good and bad chimney con-
nection.

The flue must be well isolated and circular if possi-
ble. 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.
The chimney pot must have an exit section dou-
bled than the one of the chimney, in order to make
easier the exit of the smoke. The chimney pot must
be enough tall to lean out over the reflow zone
generated by the roof: if you are not sure about
this contact experienced technicians. If you are
in a windy place, it might be necessary to install
windproof devices.
