Installation of a stove in a bath with an external furnace

If you decide that you will begin to heat an oven from an adjacent room, and the structure itself will have an external combustion chamber, then it is necessary to decide how to install such equipment. It is important to know how to build in the wall of the remote furnace. A lot of masters are wondering what is needed for this, and what materials are to be used. The installation of a stove in a bath with an external combustion chamber implies the withdrawal of the latter into an adjacent room, this indicates that an opening will need to be made in the wall. It's about the wall that separates the rooms of the bath.

It should be noted that it is most appropriate to create such an opening by the method of laying this part of the wall into a future project. This will be much easier compared to if afterwards you have to cut a hole in an already erected wall. However, in a situation where, after the construction of the bath was exploited for some time, and then you decided to change the oven, this option also has the right to live.

Selecting the size of the opening

If you will be installing a stove in a bath with an external firebox, it is important to choose the correct hole size in the wall. This parameter will depend on several factors, among them one can distinguish the dimensions of the fuel channel of the furnace, the type of material at the base of the wall, as well as the rules for isolating the fuel channel.

Dimensions of the fuel channel

If you are installing the oven in a bath with a remote furnace, it is important to give the dimensions of the furnace, namely the height and width, a special value. These parameters act as the base data, which must be used in the course of work. The depth or length of the fin will not affect the dimensions of the opening in any way. However, when buying a steel stove with a remote furnace it is necessary to take into account the thickness of the wall through which the furnace will be emitted. It is necessary to add 5 cm, which act as the distance between the vertical surface of the heater and the wall. Thus, the length of telescopic channels in different models of furnaces can vary from 160 to 300 millimeters.

Execution of the furnace through a concrete or brick wall

Installing the oven in a bath with an external combustion chamber assumes the formation of an opening in a concrete or brick wall, which will depend on the height and width of the furnace. For different furnaces, the dimensions of the opening can vary from 40 to 60 cm, with respect to height, and also within 25 to 50 cm, which is true for the width.

If the heating furnace equipment is installed on the foundation, then it must also be taken into account. To the dimensions of the furnace it is important to add about 10-20 millimeters on all sides. This indicates that there should be a small distance between the wall and the box, because when the material is heated the material will expand.

Installation of the oven in a sauna with an external combustion chamber provides for the sealing of the gap by the method of sealing with a heat-resistant elastic material. As it can act asbestos cord, mineral or basalt wool. Among other things, if the brick walls are offered to be lined with a lining, then from the furnace it is necessary to retreat in all directions about 10 cm or more. The remaining open surface on both sides should be covered with a steel sheet, preferably for this use stainless steel. Preliminary in the canvas will need to make a slot for the furnace.

Excavation of a firebox through a wooden wall

If you install the oven in a sauna with a remote furnace, you may have to work with a wooden wall. This can be a log or bar. Initially, it will be necessary to make a hole in the wall and lay it out with a brick. It is recommended to use certain calculations. To the height of the base, if it is provided, it is necessary to add the dimensions of the firebox, it is important to take into account the height of the legs. After that, add the width of the gap for expansion when heated. To the resulting figure add 25 cm of brickwork, which will spread upwards and in both directions.

Installation of the oven in a sauna with a remote furnace should be made with the help of fire safety rules. To do this, from the walls of the firebox to surfaces that are flammable, should remain approximately 25 centimeters or more. The remaining gap between the wooden wall and the brickwork must be filled with heat-resistant material.

Recommendations for work

The most correct thing is to first install the oven, then lay the bricks, and only then put the wall. By the same technology you need to act when it is necessary to completely coat the steel stove. Initially, the entire furnace is surrounded, only after the wooden partition is erected.

Distance from the side wall to the wood-burning stove

When creating an opening, it is necessary to take into account the safe distance from the side wall to the furnace equipment. If the wall is based on wood or lined with lining and is not protected, the step to the stove should be 500 millimeters. If there is a single insulation by the type of steel plate, the thickness of which is 1 millimeter, then the distance can be reduced to 250 millimeters. This is also important for the case where the insulation is made in the form of a non-flammable fibrous cement reinforcement sheet.

Installation of the oven in a sauna with a remote furnace, the price of which is from 5000 rubles, should be made at a distance from the side wall of 125 millimeters. This is true when double insulation is provided, which involves the use of a double sheet of heat-resistant material. Insulating sheets must not touch the wall. Between them it is important to leave a distance that is 3 cm. For this, steel spacers can be used as an intermediate support. Among other things, it is important to remember that insulation should also not come into contact with the floor and ceiling.

Isolation of space in front of the furnace

When installing the oven in a sauna with a remote firebox "Termofor", it is important to isolate the floor in front of the stove, which is necessary for the case when it is made of wood. For insulation it is necessary to use a steel sheet that has a size so that it captures the entire width of the fuel channel from the left and right side by 10 centimeters. Before the door of the furnace, the canvas should cover a distance that is 40 centimeters. This insulation element is recommended to be laid not only for easily combustible bases, but for all others. This will secure the space in front of the furnace from sparks and fallen embers. Among other things, sometimes there is foreign garbage when laying firewood.

Metal protective screens

If you are thinking about how to install the oven in a bath, the installation features described in this article will allow you to exclude errors. Some furnaces are sold together with a protective metal screen. When installing the furnace, it is able to replace the brickwork. For them, it is necessary to cut a hole in the wall, as in the case of a brick. There are floor and side screens, which are designed to protect the floor and walls from possible fire. Whichever method is used for the integration of the fuel channel into the wall, the most important condition is the need to comply with fire safety rules.

Features of the work on the embedding of the fin

If you decide to start the installation of a stove for a sauna with an external furnace, it is important to take into account all the nuances, because of this, first of all, will depend on fire safety. If the oven is installed close to the wall, then the latter should be protected with a minerite cladding, which is created on a metal frame. Under this layer there should be a layer of thermal insulation, as well as a vapor barrier material. After you can create a tunnel in the wall, it must be covered with ceramic bricks. Between the brickwork and the wall it is necessary to lay basalt insulation.

Installation of a furnace for a wall with a significant thickness

If you want to work with an oven that has a shortened remote furnace, you can make a safe installation in a wall with a significant thickness. In the partition, it is necessary to create an opening in which a fireplace niche should be laid out, while decorative bricks should be used. Above the brickwork, it is necessary to install a flat jumper made of metal sheet. The thickness of the latter can vary from 8 to 10 millimeters. The walls adjacent to the oven equipment must be insulated with a thermal insulator, and also vapor-insulated. Do not forget about the finish of the minerite. Above the stove to the ceiling it is necessary to fix the screen, the size of which should be 1 X 1 meter. Between the protective screen and the ceiling it is necessary to provide an air gap, the thickness of which is 3 cm.

The need for a foundation

The installation of a metal furnace in the bath with their own hands can assume the need for a foundation. If the mass of the furnace is not more than 700 kg, then it is not necessary to equip a separate base. However, if it is supposed to impose a construction, and also provide it with a furnace screen, the foundation is most likely needed. If the weight is less than mentioned, then you can manage with good lags and a massive board, which you need to lay on the floor. In the presence of a foundation, its dimensions should be more than 15 cm from all sides in comparison with the dimensions of the furnace itself or the screen. These requirements are especially important, since safety is paramount.
