What should be the chimney for a sauna stove. Chimney installation by own hands

Modern baths with a built-in chimney began to look much more attractive than those that our ancestors had. They had to wash and bathe in a "black" way. Now in the baths there is neither settling soot nor carbon monoxide. In this article we will tell you what should be a chimney for a sauna oven and how to install it yourself.

What is a chimney for a sauna stove?

Before writing about the requirements for the chimney, you need to understand what it is. In conventional terms, it is a kind of pipe that removes combustion products from the furnace and provides traction to support this process. That is, the chimney for the sauna oven removes smoke and creates traction.

Types of chimneys

Constructions have several classifications, most often they are divided into:

- internal;

- external.

The first is most often found in Russian baths. They do not violate the single architectural style of the steam room, in terms of economy - this is the most optimal option. All thermal energy remains inside the room. Such a chimney for a sauna oven is easy to operate, easy to maintain, it does not require additional insulation, and its traction is much better. What can not be said about external constructions. To install them, you need to make a hole in the roof of the bath, which in itself is not very beautiful.

The chimneys are made of the same materials as the designs for fireplaces and other similar equipment. Most often, stainless chimneys are produced. Apart from steel, ceramics and bricks are widely used. Very often you can find a combined model, where the steel pipe is installed inside the brickwork. Sometimes a ceramic tap is hidden in chimneys made of stainless steel. Aluminum and asbestos cement can not be used in saunas and baths, as the level of thermal conductivity and fire resistance of these materials is very low.

Requirements for structures

Chimney in the bath must meet certain requirements:

- The inner surface of the bend should be as smooth as possible, this will help in the future to reduce the amount of soot deposited.

- To achieve the best traction, the chimney must have a circular cross-section. In this case, the air will meet the least resistance.

- If you use a rectangular or square chimney, the area of the internal section must correspond to the power of the furnace. For example, for a 3.5 kW furnace, a cross section of 140 * 140 mm, 5.2 kW - 140 * 200 mm, etc. are required. The same applies to oval sections.

- In order for the traction force to be optimal and the soot to be deposited as little as possible on the inner sections of the pipe, it is necessary that the flat and horizontal pipes have a length in the total of not more than one meter.

- When the chimney crosses the ceiling of the roof, it is necessary to install a firebreaker. In these places there should not be a joint of pipes.

Different schemes of the device chimneys

Any chimney in the bath has a pipe, flanges and connecting parts. It is better to position the structure closer to the inner side of the wall. At this point the chimney will not give away the heat energy to anywhere, and the draft will be the most effective. If this can not be established, then there is another way to keep the heat - to insulate the walls. From the temperature on the street depends the speed of cooling the pipe. For regions with strong and prolonged frosts, it is better to make solid walls with a thickness of 58-68 cm, for others fit also 38-centimeter. For each furnace you need to install your chimney. The cutter is made at a height of 75 cm.

According to the installation method, two types of chimney are distinguished: front and back. The latter is attached to the outlet nozzle and usually has the usual form. Such a chimney is most often out through the roof. The attached structure is mounted to the side wall of the furnace or boiler. On the street, such a chimney is led out through the wall, after which the pipe is raised vertically up to a given height.

Installation of a chimney to a metal furnace

Installation of the chimney starts when the furnace is installed. To do this, you need the support legs, which thanks to the gaps for the expansion of pipes are perfectly attached to the structure. It is best to use not iron taps, but "sandwich" channels. The upper part of the pipe is equipped with an iron plug cone-shaped. It protects the chimney from precipitation. As for the lower part of the tap, it is closed with a traditional plug for cleaning pipes and draining condensate.

Installation of a chimney with a brick stove

Chimney made of bricks is usually laid out independently with the stove. The construction of the installation begins when the last row of the furnace stone is being laid. Some begin to create a chimney, when the brick hides the side doors of the stove. On the 21 rows of masonry, two bends are formed, each of which will be one brick wide. Above they will be united in a single channel. The space above the core overlaps, and the gap between it and the outlets is filled with a mineral wool. On the 22nd row, free space is completely hidden, and the process of connecting the taps to a single channel begins. Gradually, the chimney from the brick is narrowed until the space inside becomes equal to the width of one stone. At this point, install 2 latches through the row. After the styling turns into a classic raspushku. If you are not very familiar with the technology of brick installation, then such a task as building a chimney with your own hands, you can not do it. It must be carefully monitored to ensure that cracks do not form during cladding.

How to mount the chimney yourself?

The easiest way is to make a chimney for a stove from stainless steel. For self-installation, some tools and materials are required:

- 3 galvanized elbows, 2 of which are 16 * 120 cm, 1 - 20 * 120 cm;

- tee with a plug for 16 cm;

- 3 knees of stainless steel - 16 * 10 cm;

- fungus 20 cm.

All pipes must be fastened with screws. In the roofing plate make a hole with a diameter of 16 cm. Heat insulation, tiles and other materials that are on the roof near it, you need to remove. The outer part of the pipe is wrapped with basalt wool and is tightened additionally with an asbestos cord. On top of it, a pipe is put on, fastened and smeared with a bitumen mastic solution. That there were no gaps between the taps, you also need to reel the cord from the asbestos. This will save pipes from moisture and mold and fungus.

What to do with the finished chimney?

There are ready chimneys, the price of which starts from 400 rubles for 1 unit. How to install them correctly? The pipe for removing smoke is put in such a way that the care to the outside is not less than 50 cm. At the junction of the roof with the chimney, an "otter" is made-a sealed suture to protect the pipes from precipitation. If there is soot inside the ducts, the chimney is installed poorly, perhaps there are cracks or gaps in the structure, which cause the resin to settle on the surface.

Cleaning the chimney for a sauna oven

Absolutely any chimneys, whose price is 500 or 5000 rubles, need constant cleaning. It is best to use a mechanical method of cleaning with brushes and special weights. It happens that this procedure is accompanied by blows of a sledge hammer with a hammer. Clear stainless steel chimneys preferably on the street, as it is very dirty work with a lot of dust and soot. Usually other elements of the chimney are covered in packages or newspapers in advance. You can use a conventional brush, it is pushed inside the channel. As soon as the resistance of the soot weakens, the pipe is completely cleaned.

Some owners of baths clean the chimney for special cleaning, photos of such manipulations are found in building magazines. They throw a lump of snow inside the chimney. You can clean the pipe by tapping its outline with a hammer from the outside. Many bath attendants use aspen wood, which, when burned, creates a special craving. It allows you to remove the ash from the pipe. The strong dry heat of the aspen and coniferous trees contributes to the faster burning of resinous substances in the pipes. Some resort to more economical options. Potato purification has the same properties as firewood from aspen. However, it is not always possible to procure raw materials in the right amount. But if such an opportunity exists, it will save your expenses and forces several times.

There are special chemicals that help to clean the chimney. Photo, cost and characteristics of such funds can be viewed in various construction publications. The drugs carry out all the soot together with themselves, some substances loosen the soot, and it falls off by itself. Experienced bath attendants advise cleaning the chimneys in the baths after the rain.

The correct installation, simple maintenance and timely cleaning are all that is necessary for the efficient operation of the chimneys of the sauna stoves.
