8.9. The chimney pot
Must be windproof.
Must have an inner cross-section equivalent to that of the chimney flue and an outlet smoke passage cross-
section equal to at least twice the inner cross-section of the chimney flue.
In the case of paired chimney flues (which should be at least 2 m apart), the chimney pot that receives the solid
fuel product discharge or that of the highest floor must be at least 200 cm above the other.
Must go beyond the reflux area (in Italy, refer to Standard UNI 10683)
Must allow for maintenance operations to be performed on the chimney
8.10. Indirect air intake
Prepare, at floor level, an air intake with a useful surface area (net of any meshes or other protections) of at least 80
cm2 (diameter 10 cm).
In order to avoid draughts, it is advisable to place the air intake behind the stove or behind a radiator.
It is advisable not to have it in front of the product to avoid draughts.
The inflowing air can come from an adjacent room provided that:
The flow does not encounter any obstacles as it travels though permanent openings communicating with the
outside
The room adjacent to the installation room is never depressurised with respect to outside.
The adjacent room is not used as a garage or for activities causing a risk of fire, nor is it a bathroom or a bedroom.
The adjacent room is not a common room of the building
In Italy, Standard UNI 10683 indicates that ventilation is sufficient even if the pressure difference between the external
and the internal environment is maintained at 4 Pa or less (Standard UNI EN 13384-1 non-exhaustive example).
The installer who issues the declaration of conformity is responsible for this.
