The quality of the work of the fireplace largely depends on how correctly all the instructions were followed during installation.Thus, professional craftsmen recommend following the following rules:

  • When determining the place where the fireplace will be located, it is important to ensure that the walls and ceiling surface adjacent to it are resistant to high temperatures;
  • arrangement of the fireplace assumes the presence of a level stone or ceramic as a base;
  • as a safety measure, the base of the firebox should be equipped with a sheet of steel, the thickness of which should be more than 2 mm;
  • The role of insulating material will perfectly perform a wool on a basalt base, which should be placed between the surfaces of the floor and ceiling. Such wool is highly heat-resistant (heating up to 900°C will not cause it any harm);
  • one of the peculiarities of laying the firebox is the need for its gradual rounding, for which each of the following bricks must be stacked 6 cm closer from the beginning of the previous brick;
  • The remains of the mixture of mortar, formed after the laying of a number of bricks, it is required to remove with a sponge;
  • speaking of such a parameter as the thickness of the walls of the furnace, it should be remembered that the side walls of this parameter should be 20 cm, and the back edge. 10 cm;
  • provided that if the fireplace is installed in a structure made of stone, its arrangement can be carried out near any desired wall. But if the main element of the structure of the house is wood, then before installation it is necessary to build a special layer of protection. For this purpose, either standard bricks or building blocks can be used;
  • the diameter of the grids installed in the decompression chamber must correspond to the capacity of the furnace used;
  • In order to ensure that the surface is not damaged during the operation of the fireplace, the chimney pipe is important to extend beyond the roof at least 1 meter;
  • Those parts of the chimney that cross the attic room, it is necessary to treat a layer of insulation;
  • joint of the fireplace firebox and chimney pipe must be completely airtight;
  • in order for the chimney outlet to receive the air necessary for ventilation, it is necessary to provide a 5 cm clearance in the chimney outlet area;
  • the minimum height of the firebox above the floor surface is 20 cm;

How to furnish the fireplace stove with your own hands

Cladding the fireplace firebox is a necessary process. It is needed not only for decorative purposes, but also for the furnace to have a fulcrum. Chimney stove is not just a decorative element, but a real heating device that operates on solid fuel, which is used both as the main and additional, auxiliary source of heating in the house.

Many people, buying a fireplace stove, immediately enlist the help of professionals in order to perform its installation and cover it with brick or other fireproof materials. However, if you want to do everything by your own forces and are not going to resort to the help of stovesmiths and craftsmen, we recommend that you read the tips and recommendations from this article in more detail. You can always buy ready made fireplace cladding in our online store.

Chimney installation

The chimney will be made of two parts. The lower part from the firebox through the first and second floors to the exit to the attic is a sleeve made of stainless steel. steel was assembled “by smoke” and was firmly encased in brick. The upper part was made through the cold attic with access to the roof and the height according to SNIP at least 0.5 m. Above the ridge is a stainless steel sandwich gathered by condensation. The structure is very heavy, the chimney was taken out of the furnace and finally has a separate base for the brickwork and not in contact with it in any way.

The chimney sleeve and sandwich had to be assembled by ourselves after the furnace was installed in its place and about half of the furnace was laid. Brickwork had to be done after the furnace was laid. Stainless brackets, which were purchased along with the pipe, were used to attach the sleeve. The chimney was put autonomously, for which there were reasons:

  • Nothing prevented it from making temperature fluctuations.
  • Oscillations of other structures such as floors, partitions, roofs and others were not affected.
  • No one excluded fire requirements and SNIP.

No difficulty was experienced during installation. Chimney installation took half a day. Difficult work, especially on the roof was helped by a neighbor.
