.
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.

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);
