Posted by on August 7, 2020

The correctness of its devices depends not only on the efficiency of furnaces, fireplaces and other similar heating devices, but also the security of residence in the house. Smoke, the inverse traction, and finally a fire – all this can happen as a result of ill-conceived and irresponsible attitude towards the chimney. Installation of flues should be carried out in accordance with the Rules of the production pipeline, furnace work, developed VDPO: Smoke channels (pipes), stoves and other heating units for solid fuel shall ensure the complete removal of combustion gases in the atmosphere, for each furnace and each heating unit should be include, as a rule, a separate stack; Chimneys should arrange vertically without ledges, and without reducing the cross section, cross-sectional area chimney must be at least square dymootvodyaschego pipe heating system, the height of chimneys for furnaces along the entire length should be at least 5 meters, metal pipes shall be of high quality special alloy steel with high corrosion resistance, a wall thickness of not less than 1 mm, the joints of links hacking pipes should be placed outside the intercommunication and attic floors, the chimney is necessary to provide apparatus for cleaning canals of soot deposits; Construction of Buildings of combustible materials (walls, partitions, ceilings, beams), adjacent to the smoke channel must be protected from fire cutting of noncombustible materials; When crossing the smoke channels design slabs of combustible materials should arrange horizontal cuts. The rise of chimneys should be: at least 500 mm above the flat roof, no less than 500 mm above the ridge of the roof at the location of the pipe on distance of 1.5 meters from the ridge, not below the ridge of the roof at the location of the chimney at a distance from 1,5 to 3 meters from the ridge, not below a line drawn from the ridge down at an angle of 10 degrees to the horizon at the location of the chimney at a distance of more than 3 meters from the ridge. Also, be aware that the chimney should be lifted to 500 mm above the top of the building, attached to heated buildings. Chimneys on the buildings with roofs of combustible materials should show above the ridge to 1-1,5 meters. Also on the rise of the flue affected by the presence of adjacent higher buildings or structures. For chimneys are the most important indicators of craving, which is calculated from power relations fireplace, type of heating system, number of turns, height and cross section of chimney, fire and acid. On the thrust may affect: tightness chimney; Blockages, obstructions, narrowed section of the chimney, the impact of wind backwater zone, improper tip location relative to the ridge, the low temperature of exhaust gases.
