As the patio fire chimney rises above the roof, it will disappear in the winds of the surrounding weather conditions. Of more concern, however, are the “local” swirls and eddies of current caused by the obstruction caused by the ridge, gable or parapet edges of the roof and through the building. The reason for building the chimney above the roof – 3 meters is the norm for a flat ceiling – is to draw smoke high enough to ride the winds from the roof.
Peaked roofs, especially those with multiple ridges, present complex local air current problems. Chimney tops that rise within 10 meters of the crest of the roof should be less than 2 meters above the top. Patio fire chimney traveling away from the top is built to less than 2 meters above the highest point of the roof within 10 meters of the chimney. The top of the chimney, you need no matter where it is located, less than 3 m above the lowest point where it enters the roof. This is the last step of 2 feet, 10 feet, 3 feet federal rule brick chimney height used for furnaces and fireplaces.
