A chimney is an engineering structure for removing burnt products. The composition of the chimney determines the efficiency of all components (fireplace, sauna furnace, boiler), the efficiency of the heating system as a whole. Calculation of chimney pipes is a difficult and responsible job.
The best shape for a chimney device is a cylindrical surface, t.to. streamlined shape does not interfere with smoke removal. The shape and material of the structure is determined by engineering calculations. Today, acid-resistant stainless steels are used, since they are fully suitable for the installation of sauna inserts, fireplaces.
The size of the chimney (diameter) is determined according to calculations. It depends on the ratio of the height of the chimney, the number of turns in it to the power of the boiler. The height of the chimney is also determined by the calculations performed by qualified engineers.
A very important task is to fix the chimney. The metal from which the element is made undergoes thermal expansion under the influence of temperatures. Please keep this in mind when installing.to. there may be a crushing of the lower parts of the element by the upper ones.

If the chimney has horizontal sections, then their length should not exceed 1000 mm (according to the laws of physics, smoke, like heated air, is understood above). Often it is these sections of the chimney that become clogged faster than others, because. to. soot accumulates here.
Remember the need to install the chimney. Elements located outside, in utility rooms without heating, near plastic and wood structures must have fireproof thermal insulation.
