Chimney
The chimney is a particularly important element for correct stove operation.
The chimney must be sized so as to guarantee the draught declared by the Manufacturer.
Do not connect the stove to a collective chimney.
.
The chimney must be built applying the following regulations:
•
it must observe product standard EN 1856-1;
•
it must be made of materials that are suitable to guarantee resistance against normal mechanical, chemical and thermal stress
and be correctly thermally insulated to limit the formation of condensation;
•
it must be mainly vertical and not feature any bottlenecks along its entire length;
•
it must be correctly spaced with an air gap and insulated from flammable materials;
•
there must be a maximum of 2 changes in direction and angles must not exceed 45°;
•
the chimney inside the home, however, must be insulated and can be inserted into a skylight shaft, as long as it respects
standards regarding placing inside a tube;
•
the smoke conduit must be connected to the chimney using a "T" fitting with an inspection collection chamber for combustion
residue and especially for collecting condensation.
! IMPORTANT
It is necessary to check the safety distances that need to be observed when there are
flammable materials and the type of insulating material that needs to be used is on the
chimney data plate.
Use watertight pipes with silicone seals.
It is forbidden to use the discharge mounted directly on the wall or directed towards indoor spaces and any other
type of discharge that is not set forth by the regulation in force in the country of installation (Note: in Italy only
roof-discharge is allowed).
Chimney pot
The chimney pot, i.e. the top end of the chimney, must fulfil the following characteristics:
•
the cross-section of the smoke outlet must be at least twice the internal cross-section of the chimney;
•
it must stop water or snow from getting in;
•
make sure the smoke is taken away even when there is wind (wind resistant chimney pot);
•
the outlet height must be outside of the reflux zone (refer to national and local regulations to calculate the reflux zone);
•
it must always be built at a distance from antennas or dishes, it must never be used as support.
Installation
For appliance installation and use it is necessary to observe all of the local, national and European laws and
regulations.
Stove installation and the preparation of the building work must observe the regulation in force in the country of
installation (ITALY = UNI 10683).

authorised by the Manufacturer. The staff in charge of installation must issue a declaration
of conformity of the system to the buyer, whereby they take full responsibility for the final
installation and good operation of the installed product.
