  2. If the roof is flat, then the outside of the chimney must have at least 1 m of height.
  3. In cases where the roof is pitched, it is necessary calculate the distance from the chimney to the ridge, if it less than 150 cm, then it should rise 50 cm in height, if about 300 cm – on the same level.

For the correct calculation of this parameter, you may need specialist consultation to comply with all rules and regulations fire safety.

Before proceeding with the masonry, some calculations. This process can well be dealt with on your own. With the right calculation, a high-quality chimney will come out, which means the amount of fuel for heating will be minimized, all waste from combustion will go out without difficulty, and in The room will circulate fresh air.

A correctly calculated chimney height parameter will allow organize a good draft, which means that the combustion process will as high quality and effective.

Fire safety should be calculated depending on wall thicknesses: wide – will heat up for a long time, while one layer of brick will warm up in just an hour.

Calculate each parameter in individually, depending on the room, roof, and type of heating system.

The form Each element must have identical dimensions.

Then you need to start the selection of components for the solution. The composition should include: sand, clay, water, cement. Each component affects the quality of the chimney: a fine fraction of sand, high-quality cement, clay without impurities. Having similar source materials you can independently build any chimney.

Masonry process

The masonry process

Chimney masonry tools:

  • grinder (for cutting a brick of a certain size);
  • ruler;
  • marker (for data accuracy).

Before laying a chimney out of brick, you need to consider one important point – the solution layer must be small so that The strong and reliable design turned out. Masonry process standard – as for the construction of any building: each row must be shifted half the brick sideways to get maximum grip.

When forming a cut and otter, experts recommend use metal rods that must be mounted in brickwork, but the fittings should not cross the smoke channel. How to make chimney clogging minimal soot inside almost did not settle on the walls? Need to smooth walls of the structure using plaster.

During the construction of the chimney walls, leave small openings so that the cleaning process does not cause inconvenience.

Build a riser

Building a riser

The riser must be folded in the attic (roof), while it must be made close to the roof. Directly in her a hole is made (or the roof is partially disassembled), through which will be conducted pipe out. The riser height must be higher than the height of the ridge.

After about 10-15 rows you need to perform the neck of the chimney, whose parameters are optional. Arrange at the very end head on top of which you can install a cap or weather vane.

To complete the construction, you need to mount and thermal insulation that ensures efficient heating system.

As you can see, you can build a chimney out of brick yourself, taking into account the recommendations of specialists and adhere to the technology.
