Chimney installation recommendationsBackBack

Modular systems Stainless steel flues are designed for removal of exhaust flue gases from the boiler. They are: Single system (without insulation), thermal systems (with a heater). Made of heat-resistant stainless steel grades AISI 201, 304, 321 thickness 0.5 0.8 1.0 mm. and AISI 316 brands thickness of 0.5 mm. Proposed diameter range from 100 to 1000 mm and thickness of heat insulating material (basalt wool) - 30, 50 mm.

Single chimney system (shells)

Elements of single-walled chimney systems are intended for use as inserts in existing or newly built brick chimney channels. Ensure the preservation of the inner surface of the damaging effects of condensation. Quick heating steel displays "dew point" outside of the chimney, thus reduces condensation on the inner walls. Single flue systems minimize soot build-up on the smooth surface of the channel, and ensure the operation of the heating system. Operating temperature single-system-hoods.

Thermo chimney system (insulated chimneys)

Elements of thermal chimney systems intended for use in the construction of an independent, used to remove waste products from heating appliances that run on different fuels. The system is resistant to high temperatures, acids and weathering. Between the inner and outer pipes means insulating layer of basalt wool. The thickness of the insulating layer depends on the type of boiler, the type of structure and materials used. Smooth inner tube wall chimney soot reduce the possibility of subsidence. Operating temperature system thermal chimneys.

The use of hoods

Application of the system is the selection of relevant parameters and the diameter of the flue depending on the characteristics of the boiler and the height of the existing chimney. The diameter and shape of the channel chimney must ensure the smooth introduction of its single-element system. In the case of curvature, axial displacement or small internal dimensions of the chimney of the old single-use system can be possible.

Application of the system is the selection of relevant parameters of a new chimney, its diameter, dependent on the type of appliance, height and location, based on the requirements of environmental protection, as well as the shape and size that are located near buildings.

Total height of the smoke channel from the boiler to the throat tube to be usually not less than 4.5m, providing the necessary dilution and creates cravings. In the camp without houses, provided that a stable thrust stack height channel can be received less than 4.5 m.

Chimneys rise above the roof of the building should be taken:

not less than 1200 mm above the flat roof;

at least 500 mm above the ridge of the roof or parapet - at the location pipes over a distance of 1.5 m from the ridge or the parapet;

not below the ridge of the roof or parapet at the location of the chimney at a distance of 1.5 to 3 m from the ridge or the parapet;

not below a line drawn down from the crest at an angle of 10 ° to the horizon - at the location of the chimney from the ridge or the parapet over 3 m.

In all cases the chimney height above the adjoining part of the roof must be at least 0.5 m, and for houses with adjoining roof (flat roof) - at least 2 m.

The retreat from the elements of structure and sheathing the passage of smoke channel through the ceiling and roof must be:

Pipe insulation - min 200 mm,

for pipes without insulation - min 500 mm.

Set single-wall chimney system recommended no closer than 1m from walls and flammable surfaces (wood, wallpaper, etc.) at a minimum distance from existing chimney (if any), and the free distance should be at least 1.25 m. Distance to combustible surfaces can be reduced to 300 mm when using thermo-chimney system or if flammable materials cover plaster 25 mm thick metal sheet or top layer of insulation material.

The connection elements must be outside ceiling beams. Construction of houses from combustible and hard combustible materials adjacent to the smoke channels must be protected from fire by performing rozdilok and indentation. For cleaning and control of Single-mounted system at the bottom part of it in an accessible place should establish cleansing hole (revision). For condensate and precipitation that fall into the smoke channel must arrange the condensate drain that runs both the lateral and vertical tap.

Collection of modular system


• Chimney consistently meets the elements "for condensate", ie inner tube should be directed downward.

• Brackets and clamps installed as the installation of a vertical pipe with subsequent final fixing clamp on the bracket after complete installation of pipes (the place) and verify its vertical position, also recorded and stretching (if needed).

• Passages through the pipe wall and ceiling cut 400 mm more diameter outer tube and pipe laid around cotton "PAROC" and closed flanges.

The method of construction of thermal chimney system similar method of constructing single-system.

In the case of a large chimney height must use a standard range of mounting elements carrying the load segments mounted on them smoke on the supporting elements of the system below.

Number of mounting elements and the distance between them

As a mandatory element of the carrier, the construction of thermal systems, you must use the stand or bracket with clamp for load distribution. With the rise of the chimney above the roof more than 2 meters must use extensions using the clamp.

When passing through the chimney intermediate floor or wall jointing applicable elements of fire, and through the roof - a roof passage node or decorative cap.

The warmed air ducts should mount plug from the bottom up method, combining individual elements of the system so that the upper inner tube element chimney system included inside lower inner tube element, that is, "For the condensate." All elements Thermo system should fasten together.

After completion of installation work, check the tightness of joints and availability of traction in the channel. For quality check should be thrust to open the bottom of the channel bring a candle flame or a thin strip of paper. Deviations flame or paper strips in the direction of the channel indicates the presence of traction. For qualitative determination of the dilution channel micromanometer to use any type of measurement error of less than 2 Pa. Dilution channel must be at least 10 Pa (for the fireplace without door - at least 15 Pa). At lower values ​​of dilution should increase the height of the smoke channel. To check the tightness smoke channel should connect to whitewash chalk or lime suspension, and channel light material, separating the combustion of large amounts of soot (roofing material). The absence of soot to whitewash evidence of tightness.

Identified areas of penetration of the smoke channel rewire the use of heat-resistant sealant and repeat the test.


Responsibility for proper selection and subsequent safe, durable work relies on the chimney installation company which decides Installation of a heating equipment.
