■ Chimneys – UNI 7129/01
The chimney constitutes the outlet point of
exhaust fumes from a single flue or from a series
of branched flues.
Although the chimneys may have various sizes
and shapes, they must nevertheless comply with
the following requirements:
- Have a net outlet cross-section at least double
that of the single flue or branched flue in which it
is inserted.
- Have a form such that prevents the infiltration of
rainwater or snow into the flue or chimney.
- Be constructed in a manner that guarantees the
free discharge of exhaust fumes regardless of the
direction and inclination of the prevailing wind.
In order to prevent any backpressure from
obstructing the free passage of the exhaust into
the atmosphere, the following minimum height
requirements must be satisfied (fig. 1):
1. Flat roof
If the chimney is further than 5 m from the highest
point of the roof, it must be at least 0.5 m higher
than the edge of the roof itself.
If the chimney is 5 m or less from the highest
point of the roof, it must be at least 0.5 m higher
than this highest point.
2. 15° pitched roof
If the ridge of the roof is further than 1.85 m from
the chimney, the chimney must be at least 1 m
higher than the edge of the roof.
If the ridge of the roof is 1.85 m or less from the
chimney, the chimney must be at least 0.5 m
higher than the ridge itself.
3. 30° pitched roof
If the ridge of the roof is further than 1.30 m from
the chimney, the chimney must be at least 1.2 m
higher than the edge of the roof.
If the ridge of the roof is 1.30 m or less from the
chimney, the chimney must be at least 0.5 m
higher than the ridge itself.
4. 45° pitched roof
If the ridge of the roof is further than 1.50 m from
the chimney, the chimney must be at least 2 m
higher than the edge of the roof.
If the ridge of the roof is 1.50 m or less from the
chimney, the chimney must be at least 0.5 m
higher than the ridge itself.
5. 60° pitched roof
If the ridge of the roof is further than 1.20 m from
the chimney, the chimney must be at least 2.6 m
higher than the edge of the roof.
If the ridge of the roof is 1.20 m or less from the
chimney, the chimney must be at least 0.5 m
higher than the ridge itself.
