Chimney, installation and operation rules

Installation and operation of the chimney

Preparing for installation (basic requirements)

For flue furnaces manufacturer recommends using modular chimneys walled stainless steel with a diameter of 120 to 200 mm (depending on the model of the boiler - the furnace). This chimney is efficient, durable and requires minimal effort for installation and operation. The ideal solution is to install prefabricated modules with insulation "sandwich" type.

It should be understood that the use of thick-walled tubes will lead to intensive deposition of soot and condensation on the internal walls of the pipe due to increasing the duration of warm-thick wall and a rough surface in contrast to pipes recommended doped with a polished inner surface walls.

When mounting the flue away from the outer surface of the pipe to flammable home designs must be - at least 500 mm,

in the protection of the metal sheet walls of asbestos board thickness of 8 mm or 25 mm thick plaster on the metal net - not less than 380 mm.

Chimney should, if possible, have a minimum number of bends. Straight pipe is most preferred in any case, since a large thrust force, rather than bent.

Chimney height, measured from the grate to the mouth at the top, should be not less than 5 m. The height chimneys placed at a distance equal to or greater than the height of the solid structure, should be performed speakers:

• not less than 500 mm - above the flat roof;
• not less than 500 mm - above the ridge of the roof parapet or pipe at the location closer to 1.5 m from the ridge or parapet;.
• not below the ridge of the roof parapet or - at the location of the chimney of 1.5 - 3 m up to the ridge or parapet;.
• not below a line drawn down from the ridge angle of 10 ° to the horizontal when the location of the chimney from the ridge in the region of more than 3 m.

Chimney should be displayed above the top of the higher structures, and attached to the building.

When assembling the chimney in buildings with roofs of combustible materials obeskotlat tru6u spark arrester of metal mesh with openings no larger than 5x5 mm.

To prevent leakage of smoke into a heated room place all modules compound chimney between and a boiler temperature-resistant sealant necessary to seal ensuring tightness of joints pipe.

When passing through the tubes through the ceiling is necessary to perform a breaker. Cutting must be greater than the overlap thickness (ceiling) of 70 mm. Should not rely or rigidly connect the boiler house with a breaker design.

The gaps between the partitions and the ceiling should be filled with non-combustible material (such as expanded clay, slag, basalt wool, sand).

The distance from the outer surface of the tube to the rafters, lathing and other parts of the roof and slow-combustible materials should be provided in the light of at least 250 mm, while insulation resistance to heat 0.3 sq. x m ° C / W or difficultly combustible material - not less than 130 mm,

Flue pipe situated in the freezing temperature zone must necessarily be meploizolirovan material withstanding mempepamyru to + 400 ° C.

To avoid condensation in the flue gases contained moisture insulation must obeskotlavat temperature chimney wall in freezing temperature zone not less than 100 ° C, apply a thermally insulated pipe-type "Sandwich". Modules chimney recommended docked on a "top inside of the water." In this case, the condensate flows into the firebox of the boiler, it evaporates and is discharged with the flue gases.

When connecting the boiler to the stationary integrated chimney, or in other cases, it is not recommended to reject the chimney to the vertical axis by more than 45 °. Removal of the vertical axis of the boiler chimney collector of the vertical axis of the chimney must not be greater than 1 m.

Absolutely forbidden collapsible compound from the boiler chimney.

Care chimneys

For the most effective and safe operation of the boiler is necessary to monitor the serviceability of the flue.

Chimney is a complex engineering structure, and in addition and fire system.

The inner surface of the chimney should be as smooth maksimalno not promote accumulation of moisture and carbon black, not prevent withdrawal of gases and combustion products. The number of bends of pipes should be made as small as possible for the same reasons.

During operation of the boiler on the inner surface of the chimney soot settles and condenses moisture. This eventually leads to a deterioration of traction, fuming, even to the fire hazard.

Planting of the degree depends on the fuel used and the operating conditions. When using softwood soot formation is more intense. moisture condensation caused by insufficient insulation or chimney using raw wood.
The use of aspen logs is recommended to reduce the soot layer.

Chimneys should be checked for suitability for use according to the manuals on the content of the housing stock (MDK 2-04.2004) on the following dates:

• brick - once every three months;
• asbestos cement and pottery from the heat-resistant concrete - once a year;
• heating and cooking stoves - three times a year (at the beginning and the middle of the heating season, and spring);
• heating stoves and boilers - once a year (before the heating season).

Before starting a new season of operation, check and, if necessary, to make cleaning the chimney soot. As a precaution nice chimney cleaned once every two months, but at least once a year.

Purification of the chimney can be carried out mechanically (using special tools, rockfish, brushes, goods, scrapers), chemically (using sold "logs - chimney sweeps") and Using our website promoted self-cleaning method which does not require manual cleaning of the chimney, since pipes themselves are purified by simple calcination furnace open flames mode once 5-7 furnaces.
