CHIMNEY CAP

The draught of the flue depends also on the suitability of the chimney cap.
Therefore, if it is handicraft constructed, the output section must be more than twice as big as the internal section of
the flue. Should it be necessary to exceed the ridge of the roof, the chimney cap must assure the discharge also in
case of windy weather (Picture 8). The chimney cap must meet the following requirements:
•
have internal section equivalent to that of the stack.
•
have a useful output section twice as big as the flue internal one.
•
be manufactured in such a way as to prevent the penetration of rain, snow, and any other foreign body in the
flue.
•
be easily checkable, for any possible maintenance and cleaning operation.

The right output section must
be at least twice as big as the
internal section of the flue
(ideal value: 2.5 times).
(1) In case of flues side by side, a chimney cap must be higher
than the other one of at least 50 cm in order to avoid pressure
transfers between the flues themselves
