Before connecting stove to an existing chimney, in addition to complying with that described above, make sure
there are no openings or cracks where air could enter and cause a temperature decrease affecting the draught.
Also make sure there are no obstructions caused by foreign bodies or a buildup of soot.
The first connection section
leaving the stove should be
vertical, whereas the flue
connection to the chimney
(which goes to the chimney
cap) must only enter by a few
cm, so as not to reduce the
cross section of the flue.
If the flue is not perpendicular
to the chimney it is advisable
to make the connection with
special steel fittings
that allow a maximum slope
of 45°.
If the walls and ceiling are
made of flammable
materials,
the parts in contact with the
flue
must
be
suitably
insulated. All connection joints must be carefully sealed, in particular where the
connection enters the flue.
If there are several heating stoves in the same home, each must have its own flue. It is inadvisable to make
openings in the flue for connecting other appliances, as this could affect the draught.
According to Standard UNI 7429, the chimney cap must meet several requirements; above all, it must have a
useful outlet cross section at least double that of the flue. It is also advisable to install an "antiwind" cap that
guarantees fume exhaust even in the presence of strong horizontal winds.
