The diameter of the chimney should not be less than the size of the output element of the heat generator, and the total height of the channel is at least 5 m. Before making a chimney, it must be understood that the calculation of the diameter of the pipe and traction forces are directly dependent. It may happen that a too large section of the pipe, even with its sufficiently large height, will not give sufficient traction. This is the main thing that you need to think about first. The main characteristics of the flue channel can be calculated, for example, by the “Swedish formula” or using GOST 9817-95 “Household apparatus that operate on solid fuel”.
