The chimney acts as an indispensable component of the heating system. The efficiency of heating and the safety of operation will depend on how correctly it will be possible to build it. That is why it is necessary to take an interest in its device even before the moment of its construction. When choosing a chimney for a stove, you can consider several varieties of such structures, they can be:
- wall;
- push-on;
- indigenous.
Technologies for arranging these chimneys are similar, but there are some differences. It is important to consider that each design can be used in a specific case.
Wall chimney installation
The wall chimney for the stove is part of the wall and runs through its inner space. It is important to consider before planning construction work that the wall must be made of red brick. Sometimes there are wooden surfaces, but in this case the place under the chimney should be lined with red brick.
Considering such a chimney for a furnace, it should be noted thatnode walls should be more than 1/2 brick in thickness. At the place where the stove is connected to the chimney, there are reversible sleeves, which are elements that have a horizontal direction. They act as part of the smoke channel.
The channels are laid out of brick, but the length of the sleeves should not exceed 2 m. For the sleeves, steel pieces are used in the form of corners, which are placed in the furnace at the stage of its construction. The outlet channel should be 6.5 cm lower than the steel angles.
The corners are usually horizontal or have a slight slope towards the smoke outlet. When laying out such a chimney for the furnace, you will need to form the walls of the sleeve, the thickness of which is equal to a quarter of a brick. This indicates that the products should be stacked on edge. It is important to ensure that the sutures are tied vertically.
The node device assumes the presence of a base, which is located on the top of the furnace or on the floor. The foundation will look like a platform filled with concrete. It must have an equal footing. After the laying of the first row begins, it is necessary to use clay mortar. It is important to align the corners. Then further bricklaying is carried out, in which a hole is made in the chimney with a door for preventive cleaning. If we are talking about a private house, then galvanized steel sheet should be laid in front of the stove, the same technology should be used when working on the chimney sleeves.
Root flue installation
Chimneys for sauna stoves are presented today in several varieties. They may be indigenous. In this case, the assembly will have a foundation for which a pit is being prepared, taking into account the dimensions of the chimney. The internal space of this part of the stove must be equal to 135 x 260 mm, only under such conditions it will be possible to guarantee the removal of smoke and normal draft.
It is necessary to deepen the pit by 30 cm. Its bottom will be filled with crushed stone or gravel, which is covered with sand. The layers should have approximately the same thickness, which is 15 cm. The pillow is compacted and well leveled.
The sauna stove, the chimney of which will have a radical design, assumes the presence of a leveling screed, which is prepared from cement mortar. It is necessary to make the composition liquid, which will ensure the evenness of the surface. Once the screed is dry, you can start laying the chimney.
Specialist recommendations
First, the first layer of bricks is set up, then you can start drawing corners using a building level or a plumb line. The masonry must be carried out to the level where the sleeve is to be attached to the furnace. Its fastening is carried out with metal corners, the second ends of which must be installed in the chimney, as in the case described above. The junction is smeared with a clay solution. The laying of products should be carried out with dressing in half a brick.
When to choose a shellchimney
Chimneys for sauna stoves can also have a built-in design. It can also be used for solid fuel boilers. Installation is carried out directly on the stove or fireplace. Among the advantages, the possibility of using asbestos-cement or steel pipes should be highlighted.
Device of a wall-mounted chimney
Boilers, stoves, the chimneys of which usually have a plug-in design, can be installed independently. That is why, before starting work, it is necessary to take an interest in the device of this unit of the heater. The difference in technology in this case is only that the chimney will be adjacent to the stove.
The system will not have a foundation, but the heater itself will act as a foundation. However, there are still a few tips that must be applied when building a chimney yourself. The structure should be brought to the ridge of the building, and when choosing the height of the pipe, be guided by the distance to the ridge. The most appropriate parameter in this case is 0.5 m above the ridge if the distance to it is less than 1.5 m.
If there are nearby wooden buildings or trees growing that could come into contact with the pipe, you can build up the knot with a ceramic pipe, which will reduce the risk of fire. At the end of the chimney, a visor should be installed that protects the pipe from rain and debris. The scheme of the chimney of the furnace assumes the presence of a grid, which is located inside the chimney, at its end. This will prevent the escape of unburned particles, such as paper.
Conclusion
Quite often, coaxial chimneys are also used for stoves, which can have a knee with a right angle. The design must contain a tip, connecting clamps and decorative overlays. The device should begin with the choice of the location of the pipe to the street. It should be closer to the heater.
