CHIMNEY CAP
•
The chimney cap should have the following characteristics:
−
Must have an internal section equivalent with the chimney one.
−
Must have an exhaust section exit not lower to the double of the chimney internal one.
−
Must be built in a way to avoid rain, snow or external body entrance, to ensure the
right exit of combustion products with any type of wind.
−
Must be positioned in order to allow the right fumes dispersion especially out of the
re-flux area. This area has different dimensions and conformations according to the
inclination corner of the covering, therefore it’s necessary to adapt the minimal
highness as indicated in the following tables:
