Masonry brick oven, stove

The transverse dimensions of the foundation should not exceed the dimensions of the oven for a half-brick on each side. From the foundation wall should separate its gap filled with sand, and the depth of the pit must be at least 50 cm
The foundation for the stove is made, usually of the same material as the foundation of the entire bath.
Its surface is leveled with mortar and covered with a double layer of waterproof material.
Masonry generally use ordinary brick and masonry firebox - refractory (when using firewood) or refractory (when using other types of fuel).
Before using ordinary bricks must hold in water for 1-2 minutes.

The whole mass is thoroughly mixed. Masonry Mortar of refractory or refractory bricks made from clay and grog.
The distance between ordinary bricks in masonry shall not exceed 5.4 mm, and between refractory and refractory - W mm. Every 4 rows you need to wipe the inside of the clutch with a wet cloth. To the furnace wall was smooth, after the second series of the corners you need to install the guide ropes with a plumb line, fixing them on nails driven into the floor and ceiling. Not allowed ligation of ordinary masonry brick masonry of refractory or refractory bricks, since the degree of expansion at high temperatures is different.
In the process of being installed masonry metal parts furnace. To set the door of the fire, you must first attach the frame to its feet of iron hoop, and she herself was wrapping cloth or asbestos cord. Bridge over the firebox door is blocked "in the castle." Other doors and dampers are mounted in the clutch with a wire cross section of 2 mm.
When installing the grates and plates above the firebox and masonry between them is necessary to leave a small gap and fill it with sand.
If your room is heated with wood, we can limit the minimum size of the firebox width - 25-30 cm, height - 35-40 cm, but if possible, the height of the fire should be increased to 50-60 cm to the furnace with the door open embers falling down under the firebox must be below the firebox door frame.
The inside of the dymooborotov not gloss over the clay, to her pieces do not fall off when dry and do not fall into the chimney.
The top three rows of bricks placed flat with ligation. If they match the vertical joints, the series should cover the steel sheets.
Chimney constructed on the entire array of the oven. It is laid out like a furnace in a half-brick and coated with cement or mortar. Chimney height above the roof should be at least 50-60 cm
Brick chimney should be removed from the wooden parts of the bath for at least 25-40 cm, depending on whether they are or not fire protection, and metal, respectively, at 75-100 cm
In addition, the installation of a metal pipe all the wooden parts of the roof and ceiling are covered with felt, soaked mud and sheathed steel roofing sheets.
Junction of metal or asbestos cement pipe with bricks reinforced with waterproof mortar. Outside the pipe it is necessary to cover the insulation material to ensure that it does not condense.
At the upper end of the tube is desirable to set the deflector (metal cone), which protects it from rain and snow and provide gas leak by the wind.
At the completion of the oven should be plastered one of the following solutions by adding a one-tenth of asbestos gypsum, lime, sand in the ratio of 2: 2: 1, clay and sand in the ratio of 1: 2, clay, cement, sand in the ratio of 1 1: 3.

Stone backfill
For stone backfill best suited natural stones, hardened sun and water, and rocks, with volcanic (basalt, granite, etc.). But you can use the stones from siliceous rocks, which are found on the banks of the natural waters.
The main criteria for the selection of the stones should be: smooth surface, appropriate size (not less than 10-15 cm in diameter), high density, the ability to withstand high temperatures, keep warm and do not crack when exposed to cold water.
Large stones should be laid down, and smaller - up. Bath heated to more quickly between the stones must be placed vertically lumps iron or steel bars.
Instead of natural stone can be used bat pieces of ceramics, porcelain or perezhzhennogo brick.
