How to make an asbestos chimney correctly
Asbestos chimney is much cheaperanalogues, and with the right installation it will last for many years. The installation rules are dictated by the features of the material: it differs in porosity and is destroyed under the influence of high temperatures.
Asbestos chimney pipes should be chosen withtaking into account the size and power of the heater. It should immediately be noted that the fire safety rules prohibit the use of asbestos chimney pipes for coal furnaces or wood fireplaces. However, for small gas stoves or as an upper part of a pipe not adjacent to the heating unit, they are quite suitable.
Asbestos cement chimney it does not have a high draft and soot quickly adheres to the walls, so it is better to choose pipes of large diameter.
Installation asbestos chimney
The beginning of the chimney adjacent to the furnace, you needmade of stainless or ceramic pipe. In a place where the smoke during cooling will cool below 300oC, you can connect it with an asbestos cement pipe. The lower section should be located strictly vertically, the following are attached either to the beams of the ceiling in the attic, or using clamps to the outer wall of the house. To install the chimney, as a rule, sections of 1.5-2 meters are used.
It is necessary to provide several windowscleaning, since soot accumulates rapidly inside the asbestos chimney. To achieve tightness of joints, it is possible to use couplings with an asbestos cement packing or steel clamps with a lining of this material. The design of the asbestos cement chimney must be as direct and vertical as possible, any bend leading to a significant reduction in thrust.
how to warm an asbestos chimney
Asbestos cement is rapidly destroyed by a droptemperatures due to condensation. To avoid this, it is necessary to insulate the asbestos chimney with the help of basalt or mineral wool. It is wound on a tube about 6 cm thick, then fixed using an outer casing. The casing can be made of stainless steel, connecting several sections with clamps. In the place where the chimney passes through the roof, you need to stop and seal all the holes. Part of the pipe that is outside the house must be protected from rain.
