Before connecting a heating 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 hindrances caused by foreign bodies or a build-up 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 other appliances, since the draught could be negatively affected.
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.
