If you decide that you will start heating the stove from the room adjacent to the steam room, and the structure itself will have a remote firebox, then you need to decide how to install such equipment. At the same time, it is important to know how an external firebox is built into the wall. Many craftsmen are wondering what is needed for this, as well as what materials to use. Installing a stove in a bath with an external firebox involves bringing the latter into an adjacent room, which indicates that an opening will need to be made in the wall. We are talking about the wall that separates the rooms of the bath.
It should be noted that it would be most expedient to create such an opening by laying this part of the wall into a future project. This will be much easier compared to if you then have to cut a hole in an already erected wall. However, in a situation where, after construction, the bath was operated for some time, and then you decided to change the stove, this option also has the right to life.
Choosing opening size
If you will be installing a stove in a bath with an external firebox, then it is important to choose the right size of the hole in the wall. This parameter will depend on several factors, among them are 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 insulating the fuel channel.
Fuel channel dimensions
If you will be installing a stove in a bath with an external firebox, then it is important to pay special attention to the dimensions of the firebox, namely height and width. These parameters act as basic data that must be used in the process of work. The depth or length of the firebox will not affect the dimensions of the opening in any way. However, when buying a steel heater with an external firebox, it is necessary to take into account the thickness of the wall through which the firebox will be removed. 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 the telescopic channels for different models of ovens can vary from 160 to 300 millimeters.
Implementation of the output of the firebox through a concrete or brick wall
Installing a stove in a bath with an external firebox involves the formation of an opening in a concrete or brick wall, which will depend on the height and width of the firebox. For different furnaces, the dimensions of the opening canvary from 40 to 60 cm for height, and also within 25 to 50 cm for width.
If the heating furnace equipment will be installed on the foundation, then it must also be taken into account. It is important to add about 10-20 millimeters to the dimensions of the firebox on all sides. This indicates that there should be a small distance between the wall and the box, because when heated, the material will expand.
Installing a stove in a bath with an external firebox provides for sealing the gap by sealing with a heat-resistant elastic material. Asbestos cord, mineral or bas alt wool can act as it. Among other things, if it is proposed to line brick walls with clapboard, then about 10 cm or more must be retreated from the firebox in all directions. The remaining open surface on both sides must be covered with steel sheet, preferably stainless steel. First, you will need to make a slot for the firebox in the canvas.
Bringing the furnace through a wooden wall
If the stove is installed in a bath with an external firebox, then you may have to work with a wooden wall. It can be a log cabin or a beam. Initially, it will be necessary to make an opening in the wall and lay it out with a brick. In this case, it is recommended to use certain calculations. To the height of the base, if 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 atheating. 25 cm of brickwork is added to the resulting figure, which will spread upwards and in both directions.
Do-it-yourself installation of a stove in a bath with a remote firebox must be carried out taking into account fire safety rules. To do this, about 25 centimeters or more should remain from the walls of the firebox to surfaces that are flammable. The remaining gap between the wooden wall and the brickwork must be filled with heat-resistant material.
Recommendations for work
The most correct way would be to first install the stove, then lay the bricks, and only then put up the wall. The same technology must be used when it is necessary to completely veneer a steel heater. Initially, the entire furnace is lined, only after a wooden partition is erected.
Distance from side wall to wood stove
When creating an opening, it is necessary to take into account the safety distance from the side wall to the furnace equipment. If the wall is based on wood or lined with clapboard and is not protected by anything, then the step to the heater should be 500 millimeters. If there is a single insulation of the type of steel sheet, the thickness of which is 1 millimeter, then the distance can be reduced to 250 millimeters. This is also important when the insulation is in the form of a non-combustible fibrous cementitious reinforcing sheet.
Installing the stove in a bath with an external firebox,the price of which is from 5000 rubles, should be made at a distance of 125 millimeters from the side wall. This is true when double insulation is provided, which involves the use of a double sheet of refractory material. Insulating sheets must not come into contact with the wall. It is important to leave a distance of 3 cm between them. For this, steel bushings can be used as an intermediate support. Among other things, it is important to remember that the insulation should also not come into contact with the floor and ceiling.
Isolating the space in front of the firebox
When the stove is installed in a bath with a remote firebox "Termofor", it is important to isolate the floor in front of the heater, which is necessary for the case when it is made of wood. For insulation, a steel sheet should be used, which is of such a size that it captures the entire width of the fuel channel on the left and right sides by 10 centimeters. In front of the firebox door, the canvas should cover a distance that is 40 centimeters. This insulation element is recommended to be laid not only for flammable bases, but also for all others. This will protect the space in front of the firebox from sparks and fallen coals. Among other things, sometimes extraneous debris appears when laying firewood.
Metal protective screens
If you are thinking about how to install a stove in a bath, the installation features described in this article will allow you to eliminate errors. Some furnaces are sold together with a protective metal screen. When installing the ovenhe is able to replace the brickwork. For them, it is necessary to cut a hole in the wall, as is the case with a brick. There are floor and side screens that are designed to protect the floor and walls from possible fire. Whatever method is used when embedding the fuel channel into the wall, the most important condition is the need to comply with fire safety rules.
Features of work on embedding the firebox
If you decide to start installing a stove for a bath with a remote firebox, then it is important to take into account all the nuances, since fire safety will primarily depend on this. If the stove is installed close to the wall, then the latter must be protected with a minerite sheathing, 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 manage to create a tunnel in the wall, it must be overlaid with ceramic bricks. Bas alt insulation must be laid between the brickwork and the wall.
Installing an oven for a thick wall
If you have to work with a stove that has a shortened remote firebox, then you can safely install it in a wall with a significant thickness. It is necessary to create an opening in the partition, inside 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 a metal sheet. The thickness of the latter can vary from 8 to 10 millimeters. Adjoiningfurnace equipment walls must be insulated with a heat insulator, as well as vapor barrier. We should not forget about the finish with mineralite. 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.
Need to build a foundation
Installing a metal stove in a bath with your own hands may involve the need to create 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 planned to enclose the structure, as well as supply it with a furnace screen, then the foundation will most likely be needed. If the weight is less than mentioned, then you can get by with good lags and a massive board that needs to be laid on the floor. If there is a foundation, its dimensions should be 15 cm larger on all sides compared to the dimensions of the furnace or screen itself. These requirements are especially important as safety is paramount.
