Most often, the oven does not lay in the country house project, or do not build the project. The customer thinks that the main thing - to build a house, and the furnace and chimney "vkoryachim" then. As a result, to set the oven according to the rules, it is necessary to change already made by the internal layout of the premises. Wrestle with how to carry out a chimney through the ceiling and the roof is insulated. We have to change the already assembled truss system, and cut vapor barrier membrane, pull out the insulation. The main thing is that I do not understand - people putting cheapest chimney, trying to save 20 thousand. rub. down house in a few million rubles!

Case study. Familiar is engaged in complex construction of houses under the key. The client, as usual, left the construction of the furnace for later and now it is not clear where to put it. In the process of building a house "forgot" about the penetrations through the ceiling and the distance between the rafters for the withdrawal chimney. Imported furnace cost $ 180 thousand. rub. The customer says that chimney there are only 50 thousand. rub., while the furnace exhaust by 25 cm and need a 7-meter high chimney system. The result: Wise, kroili, somehow molded terminals to fit them into the existing regulations in the Russian Federation. Does not exceed. Acquaintance asks, "lights up?". I answer, that there is, but only if:

• The client will stoke the fireplace in accordance with the standards adopted in Europe, and as recommended by the manufacturer.
• The customer will only use dry wood, which was stored under a canopy of 2-3 years.
• The client will not burn the wood of resinous woods - if and pine.
• The client does not confuse with brown coal, and do not shove it into the furnace.
• The client will not throw chips into the furnace, branches and waste joinery production.
• The client will be 2 times a year to conduct an audit of the chimney and in a timely manner to clean it from soot.

Now tell me, if the client will comply strictly with these rules?

We dance on the stove! T. e., first make a design of the house with the stove and the chimney, and then proceed to its construction.

Important! Minimum height of the chimney - 5 meters the level of the grate or to the mouth of the burner tube. The height of the protruding portion of the chimney above the roof are calculated in relation to the ridgeIn accordance with the picture below.

All my friends burned bath. Cause of fire - cement-slate pipe. It overheated and cracked. Pieces of slate and sparks flew off the attic. And there are dry brooms and bath accessories. Bath was burned down to the foundation. Here's what it means - to save on the normal chimney.

A similar situation - a large bath with chopped on an unheated attic placed chimney of asbestos-cement pipes. In case of overheating it exploded. Do not put such a pipe!

Why did this happen? Air direct combustion furnace often raskochegarivayut to high temperatures. At the output of 600-800 ° C is obtained. BUT The high temperature flue gases in the asbestos cement pipe must not exceed 300 degrees Celsius. Otherwise, the material overheats. Chimney collapses, often with explosive effect and the dispersion of the fragments, and there is a fire.

5. Why do I need to comply with fire-distance when driving chimney slabs

Before we describe the tragic situation that happened to user FORUMHOUSE Vokmas describe what cutting and otstupka. So:

• Otstupka: The space between the outer surface of the furnace or the flue (pipe) and a protected or not protected against fire wall or partition or slow-combustible materials.
• cutting: Thickening of the furnace wall or flue (pipe) at the site of its contact with the building structure made of combustible material.

Cutting should not be rigidly connected to the building structure.

I burned down the house. Cause of fire in the chimney. Shrinkage overlap bar-shaped house parted module sandwich chimney. The fire left in the overlap. I have not served the chimney. I was sure that modern chimneys do not require attention during the warranty period. Call the fire department. While they were driving, we put out the fire yourself. Used fire extinguishers and water, in vain... Firefighters went for an hour. They admitted that they found us at the address and on the plume. We arrived with an almost empty barrels and still stuck at the entrance to the courtyard. Barely left. Simmer house really nothing. Firefighters turned around and went to fetch water. Returned minutes later 40-50. And what's the point? It would be better all burned, it would be less work to dismantle the house.

Chimney due to which the fire started.

Observe fire regulations when cutting and chimney otstupke and do not think that a quality sandwich chimney - the guarantee against fire.

The temperature of the flue gases the flue must not exceed 400 ° C for stainless steel tubing. Important! Leave on the outer tube to sandwich the floor structure made of combustible material, 25 cmWith the proviso that it is protected, and 38 cm to exposed surface. The space should be filled with non-flammable material.

Structures are considered protected if they are sewn on the metal sheet asbestos board thickness of 8 mm covered with plaster or 25 mm thick by a metal grid.

By the way, Vokmas I rebuilt the house again.

6. As it is impossible to do cutting and pass sandwich chimney through the roof

Consider the first example.

improper penetration nodes chimney closeup.

Lesik68 He asks what is wrong with the flue, which made the construction company, and how to fix it.

And this is an example of NikNikTar.

And the chimney, to the parents bought for the house already burning. Previous owners covered the scorched plywood beam.

When installing this chimney broken everything.

How to fix it? Dismantle the chimney and install it according to the rules set out in SP 7.13130.2013 "Heating, ventilation and air-conditioning. Fire safety requirements. "

The "distance from the outer surfaces of brick or concrete chimneys to trusses, lathing and other parts of the roof of the combustible material should be provided in the light not less than 130 mm from the ceramic pipes without isolation of 250 mm, and when insulation resistance of heat transfer of 0.3 m² ∙ ° C / W nonflammable or flammable, groups G1, materials 130 mm. The space between the chimney and the roof structures of incombustible and combustible materials group G1 should overlap combustible roofing materials. "

T. e., in the sinking of the roof, In a brick chimney, from smoke to protected sheathing and rafters must be maintained minimum distance of 25 cm. The thickness of a standard brick chimney 120 mm (half-brick) + required 13 cm in light obtain 25 cm. If you put the sandwich chimney (Structure with two metal tubes separated by a layer of non-combustible insulation) then, from the outer surface of the chimney to the protected rafters and battens, leave at least 130 mm.
