Chimney for a bath: device and installation

The correct design of the pipe to remove the smoke will increase the quality of the operation of the bath. Such a device will divert in a timely manner, will not give ovens too quickly. Correct chimney can be constructed with your own hands. Consider the features of the device and its proper installation.

Peculiarities

Work on the arrangement of chimney can not be started without knowledge of the design features. For example, each manufacturer of the bath furnace recommends its own diameter and height of the chimney. Technical indicators require maximum compliance with certain requirements. The device will not be better if the thrust is stronger than the required rules.

With a strong pull, hot gases will not have time to warm the oven, they will disappear into the pipe. With insufficient pull in the furnace, there will be little oxygen. The room will be blurred, which will lead to the uncomfortable finding of a person in the bath and the possibility of carbon monoxide poisoning.

The thrust is an important indicator for a chimney, which reflects the movement of the smoke inside the design.

Air in the chimney moves from below up. To check the correctness of the direction of movement, use a candle or a grilled piece of paper to be reduced to the furnace. Fire must draw inside. With incorrect chimney device often occurs a reverse traction. The main consequence of this phenomenon is an unpleasant smell of smoke and gary indoors. Smoke and Gar badly affect people’s health, wall covering, ceiling and furniture.

The perfect chimney should be strictly horizontal. However, it is not always the construction of such a design possible. If the chimney requires a change in direction, the so-called knee is used. Modern manufacturers offer a huge selection of devices, characterized by the ratio of corners and turns. The presence of knees in the chimney complicate its cleaning. Therefore, it is recommended to use this option with the possibility of arrangement of the horizontal design.

Another feature of the bath chimney is the ability to install construction inside and outside the construction. Each option has its advantages and disadvantages. It is believed that the external chimney is less free-hazardous in comparison with the inner design. It is easier to install it, consolidate and exercise subsequent cleaning. The main lack of external chimney is large thermal losses.

If the chimney is internal, the concept of heat loss is automatically excluded. However, the installation of this design is more complicated. In addition, this design is not quite fireproof. Less deficiencies in the external and inner chimney will be used in the work of modern materials. Features of used raw materials and elements must match the characteristics of the bath. Registration of temperature in the room, sanitary standards, the structure of the bath itself (preferably the presence of wooden materials).

Views

Variants of chimney designs are selected depending on the bath construction material used. All device items are permissible to purchase in the finished form or to build yourself. Until recently, the main material of the chimney pipe was brick. It is characterized by ideal characteristics, durability, fire safety.

For the construction of a brick tube, special knowledge and skills are needed. Not for each bath, this option is suitable. Without the absence of practical experience in the masonry of a brick tube, the correct chimney is almost impossible to build. The structure of the brick has characteristic rough areas that cause soot deposition in chimney, which leads to a rapid clogging of the structure. In addition, planting sediments may lead to the appearance of sparks when crossing the furnace, which is unsafe.

Modern masters often choose stainless steel chimney for a bath furnace. The main advantage of such a device is quick installation. In addition, the chimneys from the metal are deprived of problems that may arise in a brick oven. Stainless steel chimneys are often a sandwich design. Direct Iron Chimney Bath Easily Install your own hands.

The inside of the pipe made of steel is distinguished by a smooth surface. Missing faces and roughness contribute to the best removal of smoke from the furnace. But when temperature changes on the steel pipe appears condensate. With the insulation closed, the pipe of such a phenomenon does not occur. About this effect it is worth remembering, organizing construction arrangement with their own hands.

Another kind of chimney for bath stoves – ceramic. This design is distinguished by resistance to fire, reliability. Modern pipes from ceramics are suitable for solid fuel boilers, as well as devices working on liquid fuel.

The main differences between these structures from other types:

  • Universal system (the possibility of selection of different diameters);
  • ease of processing chimney even with side passage;
  • water and parangarity (accessibility for stoves with a heater);
  • Mechanical strength.

Varieties of ceramic, metal models and brick products imply a mandatory presence in the structures of the base, capacity for the accumulation of condensate, a tee for cleaning and inspection.

The grounds for any chimneys must be perfectly even and strictly horizontal.

Options of device designs

Options for arrangements require calculations in which the amount of incoming air that ensures fuel combustion is taken into account. There are complicated and simplified methods for calculating.

For the first calculation, the optimal characteristic features of the chimney of the bath are needed:

  • Gas temperature at the outlet of the pipe +120;
  • The minimum speed of movement is about 2m / s;
  • The recommended length is 5 meters;
  • combustable fuel at one bookmark in fiber – 10 kg / h.

To calculate the diameter of the chimney, there is a formula: d = √ (2 & 4xvr / 3.14×2)

Here d – the diameter of the pipe, and VR is the amount of air.

Section geometry can participate in the height of the chimney. For this calculation make up a schedule. The graphics calculation involves the area of ​​the furnace and the pipe area. The first value must be divided into second and determine the percentage ratio.

With a sectional, equal to 10%, the minimum height of the chimney will be:

  • 7 M. – with a round tube;
  • 9 M. – with a square tube;
  • 11 M. – with a rectangular pipe.

All values ​​are valid when building a straight chimney. In most cases, smoking pipes require rotary structures that reduce traction. To prevent this, when calculating the chimney with curvatures, the resulting diameter can be slightly increased. If the stove for the bantle is purchased, the stage with the calculation of the diameter of the chimney can be completely skipped. All necessary parameters for chimneys are usually indicated by the manufacturer in the instructions for a specific model.

Internal values ​​of pipes are calculated taking into account the stove power. Standard bath pipe is 150-200 mm. It is worth considering that with an enlarged structure of the design, heat in the furnace will not be delayed. With a small section there will be no necessary thrust. When building a prefabricated design, it should be borne in mind that the diameter of the pipe sections should not be less than that of the output part of the stove.

The exact value of the height of the pipe is interconnected with the design of the construction on the roof. If the pipe turned out to be in the middle of the skate, the design is necessarily raised over the skate to the half-meter height. This parameter is closely interrelated with the location of the furnace inside. If there is not one furnace in the bath, each of them should be equipped with its own chimney system. Otherwise the normal traction will not succeed.

System of the cauldron Specialists recommend shutdown in extreme cases. There are special parameters that require maximum compliance.

To save heat in a pair chimney, you need to place closer to the inner wall. Here the thrust will be the most effective. In the absence of such a possibility of the wall must be solid and solid. With thin walls of the bath bath, you can never wait.

Elements of the chimney system

Standard kits include:

  • pipes or cylindrical panels;
  • adapters;
  • tees;
  • fixing elements (brackets and clamps);
  • nozzles;
  • End elements of various forms;
  • Top elements.

In some cases, additional components are applicable. When assembling any chimney, it is important to be guided by the construction regulatory documents and fire safety requirements. All components of the pipes that are in contact with flame or outgoing gases must be made of leaf steel with refractory characteristics. Admissible to use equivalent similar materials.

In the production elements of the chimney design, it is customary to divide into two groups. The first of them includes double pipes, sandwich panels. Elements include an outdoor and inner tube with different diameters. Among themselves, they are insulated with insulation with non-combustible characteristics. This design provides fast and best heating. This affects the rise in temperature in a short time above the dew point, which makes a smaller amount of condensate, which often becomes the cause of corrosion.

The elements of the first group are used in the designs of ventilation and smoke channels, which pass through the unheated parts of the bath (for example, through the attic). This design is applicable to external smoking arrangement. Second-order verticals that are not in contact with flame and gases are allowed from galvanized base or stainless steel. The second group of chimney elements is usually single-mounted, it has a diameter from 80 to 400 mm.

Usually, the stainless steel is allowed for the chimney device in the absence of insulation. It has a smooth touch surface.

Special elements allow you to collect unlimited in height, place and method of installing the structure, these include:

  • Wall supports;
  • installation sites;
  • Shibers;
  • taps;
  • telescopic brackets;
  • clamps, sparking, heat exchanger.

When installing can not be used double pipes as the initial element of the structure.

The initial part installed on the outlet of the stove should be a single pipe with a permissible length to meter and a metal thickness of 1.0 mm. An exception can be a stove with water capacity. To move from one type of item to another, the start of the sandwiches apply.

How to install?

To arrange the chimney, with their own hands, the perfect variant of the material are pipes from metal. They reduce the cost of construction, as well as labor costs. Mounting chimney begins to the oven already installed in the bath. Before the first knee install the usual iron pipe. Proper mount will ensure special designs with refractory characteristics.

The initial part attach to the furnace pipe. Immediately install a Sewber – a valve that will add or subscribe traction. Then the hole is performed in the roof, which can be square. Next collect a metal box with through hole corresponding to the size of the structure. Through it, the chimney will be bred in the attic. The height of the box should be more ceiling finishes materials.

The box is securely fixed in the ceiling. Free space of the box is filled with mineral wool, or clay. In the attic, the design is closed with a lid with a hole for the pipe. At the dying point of the chimney, a sheet of heat-resistant material. The upper tube is protected by sheets of mineral wool or asbestos. A special hydraulic cuffs are used as thermal insulation. Clauses can be treated with sealant.

An even smaller labor costs will require the installation of an external metal chimney. The device assumes the presence of a suitable hole in the wall (not in the roof). For the turning pipe from the furnace acquire a special knee. The taps are different, select the option you need.

The discharge is installed on the pipe stove. Then from the outside put a tee. From it, the chimney is performed upwards along the wall, if necessary down. As a wall insulation, it is properly used to use a similar metallic box filled with non-combustible bulk material.

Outside the building chimney needs to be fixed along the entire length. For this use special holders. They can be made of foolish non-combustible materials.

With the arrangement of the outer construction, it is important that it rises above the skate by 50-60 cm: this installation will be a guarantee of good traction. To prevent chimney from small garbage and rain over a special umbrella.

Brick chimneys can be indigenous or noar. The best option for bath furnaces is a native. If the furnace is made of brick, then attach the design from the same material. If the furnace is made of metal, the brick chimney is connected to a special pipe with a nozzle.

The chimney of the brick is suitable in the form of a square pillar, which is equipped with a well-shaped cross section. The size of the section is associated with the power of a bath stove, it can be half bricks, brick or two bricks. The basis for a brick design is the foundation of the same thickness with a bath stove, which makes it a single whole. The pipe is raised to the desired height where the valve is installed.

Immediately mark the place for the design on the ceiling and in the roof. For compliance with strict verticals, use the Level. Work start from the masonry of the adsadd part for which there is already a point on the stove. Perform the aisles of brick rows Exactly: any irregularities will worsen the quality of the traction force. Control the location of each row. For control, the tensioned thread is suitable between the angle of the initial row and the angle of the hole in the roof.

For the protection of the ceiling from ignition laid the flap. Flap is the expansion of the external walls of the pipe, which also provides stability of the design. The most wide place of the roller must be located at the ceiling material level. After the installation is completed, the chimney is fixed by edged boards. Next, the roller is narrowed, the pipe is aligned to the initial value.

The outer perimeter of the chimney is laying out until the roof material appears. Upstairs build a design that will serve to remove rainwater. It has increased dimensions of about a quarter of a brick. Lay out the design by a similar principle with a floss. Its height is interconnected with an angle of inclination of the roof.

It is worth considering an important nuance: the beginning of the structure should be located from the bottom of the roof and perform over the upper point in several rows.

Next lay out the neck of the chimney. Metal cap is allowed over construction. The joints of the brick chimney and roofing structures are important to carefully seal. Choose ways of work and additional elements depending with the type of roofing material. Methods of this work are different, solutions for the use of one way or another are taken at the venue of the pipe.

Properly install brick chimney with your own hands difficult. In addition, the design is the high cost. Therefore, you should not start brickwork if you saw a brick and trowel only on video. Modern materials allow to build simpler and efficient designs for a bath.

Clean Tips

After the structure of the chimney, as well as some time of use, it is important to take care of the regular cleaning of the system. The most proven way to clean the chimney – the use of mechanical instruments. For this, special rams, weights, in some cases scrap and sledgehammer will be suitable.

The work of a pipeline – the occupation is dirty, because everything is carried out from the bath in advance, the surfaces are closed with newspapers or film:

  • The easiest method is the use of a special rash, which can be cleared. The rash is enough to insert into the pipe, then it is necessary to carefully push it up until resistance runs out due to accumulated soot. It should not be thrown around the axis, otherwise there is a risk that it will get stuck in the pipe, and it will have to get parts.
  • Another effective method of cleansing chimney – the burning of aspen wood. The method will help with a small amount of soot on the surface of the pipe. When burning aspen, the best way is created, which is capable of carrying out the pipe.

  • Potato skins possess such properties. But to prepare the desired amount of material will have to be closely engaged in cleaning not one kilogram of vegetables.
  • Modern methods of protection of pipes from soot using chemicals became frequent in use. Modern drugs include special components that, when combustion, we carry out soot. Components can act as a seal separator, it will fall off the walls of the pipe as a result.

It is believed that the best time to clean the chimney – after the rain. In a humid environment it is easier to carry out the cargo. Timely pipe cleaning will be the key to high-quality firewood burning. This will save heat in the bath.
