TIPS DESIGNER

Paul recommended that you perform in front of a fireplace in stone, floor tile or metal.

unsuccessful arrangement should be considered within the outer wall of the chimney, as well as inside the walls, arranged in terms of the distance from the ridge of the roof.The chimney is located in the outer wall can create problems in the winter, and the chimney away from the ridge will strongly rise above the roof.

If the form and type of the future of the fireplace is not selected, and the time has come to lay the chimney, you can prepare a brick wall of the shaft (the size of the channel ~ 26 x 26 cm.) Or leave openings between the construction of the building, which will allow to build a chimney built in the house.

It may be useful advance left corner in a brick wall or a hole in the wood, which will later be filled with masonry and leaning against the wall will serve as a fireplace.About

hot air

When the fireplace is a constant circulation of air inside it.The heated air in the furna
ce, rising up, causing jet thrust.As a result, through a special slot and drovnitsa cold air enters the furnace.Cast iron radiators (the outer surface of the furnace gives off heat) can increase the efficiency of the fireplace.The air is in contact with the heat sink, and heated through special metal gratings in the housing falls into the fireplace room.Sometimes these gratings have shutters to regulate the flow of warm air coming into the room.The greater the heat sink temperature, the faster the flow of air.The radiator itself is not smooth and ribbed.

Ribs need to increase the cooling surface.Some furnaces have a special outlet valve, whose position can be changed via the drive - cable.If you close the valve, the hot air in the oven for longer delays and more heat will enter the room.Others flame burners controlled only the bottom flap of the air purged.Typically, the furnace is attached to the chimney using steel pipes.Now for this purpose, flexible corrugated stainless steel pipe (with zirconium alloy, gives a special strength of the product).

CHIMNEY

is largely determined by the performance of the fireplace.The basic requirements to it:

a) the height of the chimney should be sufficient to in a closed furnace to create the necessary vacuum thrust or if an open fireplace.The height of the chimney should be at least 5 meters from the surface of the burning fuel.At the height of the chimney over 12 meters have to take special measures to the fuel does not burn in seconds.After all, in the furnace of high vacuum is created, and it has to be limited.Care should be taken so that the smoke channels were not below the vent.

b) channel chimney should be insulated, made of non-combustible, dense materials, ensuring its integrity, its main part is to take place inside the heated space.In practice, the chimney is in the form of a brick shaft inside which extends a thin-walled stainless steel tube, or use special ceramic chimney sections (blocks) of different sizes.You can make the chimney in the form of double-walled metal elements with thermal insulation based on basalt fiber.

chimney section

thrust depends on it in the fireplace.The size of the cross section is selected depending on the size of the furnace.For the smallest of the furnace - a minimum of 180 mm, and for the greatest - not less than 250 mm.The wider the pipe, the more difficult "run" the fireplace.For good traction is desirable that all parts of the chimney were vertical.But if your house is already finished chimney and design considerations required to put a fireplace in some distance from him or from the side, such a possibility is certainly there.It is important that the angle of inclination of the chimney was not more than 45 degrees for closed furnaces and more than 30 degrees - to open.

CONCLUSION ON ROOF

In the case of non-flat roof is better when the chimney goes closer to the ridge and is not lower than 10 degrees from the horizon toward him.Usually, the end of the chimney should be higher than the ridge 40 cm. Special cover made of galvanized steel pipe crowns.It is made so as not to interfere with the free exit of smoke and at the same time protect it from rain and snow.For the insulation of the chimney from moisture, in a place of its passage through the roof, and use a special foam sealant.Around the pipes do "apron" made of galvanized iron, not violating the principle of fish scales, where each layer overlying roof superimposed on the underlying.

fireplace FOUNDATION WHY?

Fireplace - a house fire, and any house begins with the foundation.Why can not put the fireplace on a hardwood floor?-opasnost here is not so much a weakness of overlap, but in the fact that there may be cracks and leaks due to the mutual mobility of the floor and leaning against the wall.And anyway, right on the floor fireplace is placed only in the case if it is a monolithic platform, which is based on the foundation of the building.Often, in the initial stage of building the model and size of the future fire is not yet known.Then make a universal training places.Avoid the construction of the foundation helps lightweight modular design of the fireplace (350-600kg).Carrying console elements built into the wall, too, can reduce the load on the ceiling.

DESIGN

Fireplace - the only detail of the interior, which was built from the foundation to the roof.
foundation under the fireplace should be independent, in no way associated with the foundation of the house.In the case where both of the foundation disposed in close proximity between them making a sand filling thickness of at least 50 mm.And b) channel chimney should be insulated, made of non-combustible, dense materials, ensuring its integrity, its main part is to take place inside the heated space.In practice, the chimney is in the form of a brick shaft inside which extends a thin-walled stainless steel tube, or use special ceramic chimney sections (blocks) of different sizes.You can make the chimney in the form of double-walled metal elements with thermal insulation based on basalt fiber.

fireplace FOUNDATION WHY?

Fireplace - a house fire, and any house begins with the foundation.Why can not put the fireplace on a hardwood floor?- The danger is not so much a weakness of overlap, but in the fact that there may be cracks and leaks due to the mutual mobility of the floor and leaning against the wall.And anyway, right on the floor fireplace is placed only in the case if it is a monolithic platform, which is based on the foundation of the building.Often, in the initial stage of building the model and size of the future fire is not yet known.Then make a universal training places.Avoid the construction of the foundation helps lightweight modular design of the fireplace (350-600kg).Carrying console elements built into the wall, too, can reduce the load on the ceiling.

DESIGN

Fireplace - the only detail of the interior, which was built from the foundation to the roof.
foundation under the fireplace should be independent, in no way associated with the foundation of the house.In the case where both of the foundation disposed in close proximity between them making a sand filling thickness of at least 50 mm.

And you need to make sure that the pipe in the construction not hit the beams or rafters, that is correlated with the tube axis of the future arrangement of load-bearing structures.It creates a pipe main load, so it is possible to be positioned closer to the center of the foundation.This will prevent the asymmetrical load and, consequently, possible uneven rainfall.Sometimes it is done independent foundation under the so-called radical chimney.

Foundation dimensions depend on the weight and parameters of the fire, on the quality of the soil.Take the area of ​​the fireplace in the plan.Was added thereto at 6-7 cm. On each side.This is the area of ​​the basement.

depth of the

This is a very important indicator, because it depends on the durability of the fireplace.In the depth of the influence of soil properties.On dry sandy soils and it usually does not exceed 60-80 cm. On the ground, where there is swelling of the soil, it is necessary to lay the foundation for deeper: 150-170 cm. Below the freezing depth.



of excavation pit is 10-15 cm. Larger than the size of the foundation.It is important that the pit or enters groundwater and keep vertical walls.Getting Started tab.The bottom of the pit is covered with a layer of gravel thickness of 10-15 cm and compacted hand-rammer, after which the level is checked its horizontality.Then you can build a pile or rubble concrete foundation.


Make rubble concrete formwork.The inner walls of the formwork should be properly waterproofed with bitumen daubing or glassine lining, tar paper or roofing material.Laid on the bottom of the first layer is large (up to 15 cm in diameter) stones, filling the space between them with rubble.Laid layer watered special cement-sand mortar of 1: 3 (1 part cement, three parts sand).At one time you need to fill it with a solution of 1 row rubble laid.The remaining layers to perform better with a break of one day.After seven days, the foundation is ready for the construction of masonry.The top of the foundation should be 6-7 cm below the finished floor.

pile

In fact - it is finely recessed concrete slab thickness of 12-15 cm, reinforced in the lower layer.Conventional manual drill make cylindrical holes with a diameter of 20 and a depth of 100 cm. At the bottom of the pits and poured a layer of compacted gravel thickness of 10-15 cm. Then, fold the tube of roofing material (which will serve as formwork) and insert them into the pit - the fresh concrete.
