You know what the worst word for any homeowner? I think everyone guessed? Yes, this is a fire and how to correctly install a chimney in a wooden house, to avoid it, you will find out in our article. In fact, there are no difficulties. We must do everything according to the rules and comply with all the requirements than wake up at night from a heart -rending scream “Fire!”.
What should we do and what to do with the chimney to be safe?
But nothing, in the sense of superfluous. There is a charter in the army, and builders-a collection of norms and rules No. 41-01-2003. Describing all conceivable and inconceivable requirements, this management document will help the professional and the novice installer to understand all the intricacies of the organization of heating, ventilation and removal of carbon monoxide.
In suburban houses, baths, boilers, stoves and fireplaces are widely used. The air heating in the room occurs during their furnace. As you know, the combustion of fuel is accompanied by increased temperatures and a negligent attitude to fire safety is fraught with “bad” consequences. Particularly careful compliance with the rules should be in wooden houses. To use chimney channels, regardless of the type of heating complexes, simple requirements must be observed. There are several “golden” rules for construction and operation.
SNIP smart book says that you can not have combustible structures closer than 13 cm from brick and concrete chimneys. Ceramic products used as removal channels for hot gases have more stringent requirements – 25 cm.
Important! Long-term heating of flammable materials at a temperature of 80-900 ° C causes their spontaneous combustion!
Installation of a brick furnace in a wooden house
Since the smoke channel is part of the design of heating devices, this requirement applies to the entire complex. This does not mean that the furnace should be in the center of the room, it can even adjoin the wooden walls and partitions, but thermal protection is performed using materials that prevent heating. This is asbestos, a felt with clay impregnation. An effective addition will be a layer of sheet metal. There is such an expression – “distance from smoke”. When building brick furnaces, this indicator is 0.25 m in the presence of thermal protection and 38 cm – without it. These requirements relate to steel, ceramic and concrete materials. The rule should be observed when the chimney passes through the wooden wall, ceiling, roof.
The minimum elevation of the pipe, which goes at the highest point of the roof or in the area up to 150 cm, should be at least 0.5 m. When moving away from the center, the following principle should be observed. Imagine a conditional line passing to an angle of 100 from the skate to the horizon. So, the top of the chimney, located from the highest point at a distance of 3 m or more, should be not lower than this level. To ensure reliable traction, the total length of the pipe is 5 m from the level of the grate. The section depends on the power of heating devices.
To prevent “throwing” smoke and protect the roof from fire, sparkles and visors are used.
For stone structures, selected brick is selected, without cracks, chips, with a smooth surface. Inside the room, masonry is performed on a solution of clay with sand, with a thickness of not more than 5-7 mm, a cement solution is used outside.
Before starting installation, a reliable foundation with waterproofing from groundwater is carried out. The location should be strictly vertical.
When using steel chimneys, it is forbidden to deliver individual elements in the thickness of the walls.
The operation of the chimney consists of periodic cleaning (at least 1 time in half a year), a regular examination for the detection of cracks and cracks, impaired tightness. When identifying them, immediately repair.
Compliance with simple rules will allow you to sleep calmly, without worries about the good state of your furnace!
