A chimney cap is a device that is normally placed on top of a flue outlet for the purpose of facilitating dispersion of the combustion products; it
must satisfy the following requirements;
-have a useful exhaust section that is at least double the section of the flue outlet on which it is inserted;
-have a shape that prevents the entry of snow or rain into the flue outlet;
-be built in such a way that venting of the combustion products is guaranteed regardless of wind direction. The diagrams show how the chimney
should be constructed.
