Another important element of the system is the chimney flue. This, according to the standards (UNI 10683,
UNI 7129 and subsequent updates), should meet the
following requirements:
- Have the insight material equivalent to that of the tube.
- Have a fume exit of at least twice the size of the inner section of the chimney, to facilitate the release of
smoke.
- Be impervious to rain, snow and foreign bodies and being save against wind, in terms that the fume exit is
also ensured in the case of strong wind.
The chimney cap should be positioned at least 50 cm over the rooftop, to guarantee an efficient discharge
of combustion into the atmosphere. Not respecting this minimum distance could lead to a reflow of the
combustion and counterpression in the cinmney
Separate flues on a rooftop should have a minimum distance of at least 2m. The distance to other externals
like buildings or trees should be at least 8m.
