Solid fuel stove: fire protection rules

It seems that the one thing the world will remain unchanged, even when it changes at all: people will stoke the furnace. No electricity, no gas will be unable to displace solid ovens of our homes. Based on the experience FORUMHOUSE users, today we talk about the fire protection of facilities that use solid fuel stove.

Wood burning stoves and fireplaces - a true symbol of home comfort: the crackling of wood in the furnace, the house is distributed soft warmth... But if you do not think lightly or fire protection to save her, the oven can be a source of danger to property and life. Fire can break out due to a falling out of the furnace sparks or overheated walls. When we set up the stove or fireplace, fire protection should be a "very important item of expenditure", and save money on it should not be in any case.

I assure you that life is more expensive.

Therefore, conscientious producers of stoves and fireplaces are always written in the instructions that the installation site heaters need protection floor, walls and ceiling.

Screen

To reduce the thermal radiation from the metal heater, make shields from sheet iron or steel. The screen reduces the glow oven temperature to 100 degrees. Ready screen can be easily mounted at a distance of 50 mm to the wall oven.

Floor

Floor, on which the CT-furnace must be protected nonflammable and durable coating. Variants of the basis on which you are installing the stove, might be:

Alexey Telegin (Member FORUMHOUSE):

• for asbestos board 5 mm galvanized sheet;
• or two layers of gypsum fiber board - granite;
• stainless steel, etc.

How to determine the size of this fire retardant lining on the floor? Usually, it is made such that on each side of it is 100 millimeters advocated the furnace perimeter. Before the oven necessarily mounted predtopochny sheet which will protect against embers and sparks falling from the furnace. Depending on the furnace size, the sheet size may be small, 500h700 mm or 400h640 mm or 100 mm play for the furnace with the other moans.

Now rarely does the old sheets, nailing to the floor a piece of tin. Most interesting buy ready sheets of polished stainless steel, and for the fireplace - copper or brass, etched and decorated artistic patina.

The furnace should be at a minimum distance of 100 mm from the floor.

Ceiling

For fire protection ceiling can be used the same materials as the floor, changing only the distance from the heater.

If it is a stone furnace (fume collection pipe and the top of furnace thermal capacitance, overlapped three rows masonry), the ceiling must be at least 250 millimeters from the surface of the furnace. If the furnace of uninsulated metal (what are the most bath), the minimum length - 1200 mm. If the ceiling is protected, and the oven has thermal insulation, the distance is reduced to 800 mm.

Fire protection of the ceiling must be greater than the perimeter of the heater - add to the perimeter of the surface of the fuser 150 millimeters on each side.

Walls

For optimum fire protection solid fuel stove is placed at a safe distance from the wall, which must be protected from fire. Material and method of protecting the walls depends on the thickness of the furnace walls. Members of our portal is used for the treatment of walls fire-retardant impregnation, Mastic, foaming formulations, etc. Such fire protection needs to be updated frequently. But more users demand not FORUMHOUSE compositions for the treatment of surfaces and materials to protect them: basalt fiber mats, fire protection foil etc.

Especially popular refractory plates: vermiculite, super powers (thin plate designed for use in the defense industry and withstand temperatures above 1000 degrees +), fiber cement panel steklomagnezitovy sheet, gypsum sheet (GVL), calcium silicate (Superizol). Not all of these materials are equally good, but they can withstand long-term heating to high temperatures, poorly conduct heat and serve for a long time without losing strength.

In the baths, some still use the old grandfather's method: trim the walls with two layers of felt soaked in a solution of clay.

Alexey Telegin:

Such protection not only prevents fire, but also signals the danger of fire the smell of burnt feathers.

Embodiments and combinations

Most of these materials and methods can be applied only under certain conditions, combining them with each other and observing a number of requirements. For example, we wall trim plates of fireproofing material, wherein a certain thickness, and the metal shield oven set etc.

Here are the options to protect the walls, which are used members of our portal (both ovens are in the country, the wall - wall paneling)

- The wall is treated with flame retardant, is installed on top of a sheet of asbestos (or similar) in height from floor to ceiling, and on the sides of the stove, he speaks at 15 centimeters. On top of a sheet of drywall, and completes the "pie" - tiles for beauty.

- On the battens in staggered rows, with overlapping, apply two coats of a basalt cardboard, it closely Miners, it trapezoidal sheet roofing with round cross section. Subtlety is that the floor plate to a convention should be a gap of 5 centimeters.

A combination of several ways to make wall insulation protection reliable. And vice versa.

Redston (User FORUMHOUSE):

85% of fires occur at a time when at one point going to a number of factors, individually, in general, it is quite acceptable.

Redston gives the following example: flammability combustible construction materials are distributed into groups, and, Specifically, the group B1 includes flame-retardant, for example, gypsum fiber board, which many people use for fire protection.

Redston:

Group flammability B1 means that per square meter of surface you will need to attach a power of 35kW or more. But your stove area much smaller and iron stoves are sometimes very hot. To ignite a piece GVL area of ​​10x10 cm, only need 350 watts! GVL has low thermal conductivity, so localized heating will not be dissipated by its area. At one point, it heats up, and go!

The distance between the furnace wall and depends primarily on the type of furnace. We must bear in mind that no matter how you protect the walls, for metal furnaces distance should always lay with the stock ..

Alexey Telegin:

When regulations are neglected or unduly rely on thermal insulation, there is a fire.

A distance between the wall and the outer surface of the furnace in technical language is called Pechnikov otstupkoy. It correctly made otstupka protects the wall from an accidental spark, which can fall out of the gap of the door, and overheating, which leads to inflammation.

If the oven is a thin-walled, and the wall surface is not protected, the distance should be 500 mm. If the oven is a thick-walled, and the walls you defend to the maximum permitted distance of even 200 mm.

When you open otstupke from all sides of the furnace there is an open space.

Closed otstupka - a structure which is closed on all sides or more. How does it work, you can see from the figure below.

1. Fundam furnace. 2. The sealing layer. 3. Fireproof floor. 4. Wooden wall. 5. Shield boards. 6. Insulation (asbestos or felt). 7. Brick "on edge." 8. Oven. 9. Predtopochny sheet.

If the oven (or chimney) "bump" in any partition - is, for example, it is often in the bath when she the furnace is in the sauna room and the furnace door - in another room, and partitions between the furnace is also done otstupka. The smaller the protected design, the greater must be the distance.

At the party FORUMHOUSE Kisha has a large old house. He wants to divide it into two rooms, and at the intersection of frame partitions to put the stove. Members of our portal have advised him straight from the stove lay otstupku wide brick, and have it to attach the partition. Even better, fireproof materials will be included in the structure of the walls.

Dmitriy2791 (Member FORUMHOUSE):

For example, metal profile, thereon LSU, flat slate, leafminer and m. P. For insulation abutment to the oven fill basaltic cardboard or basalt wool and metal mask doorsteps.

In general, when installation of furnaces or fireplace should carefully examine the manufacturer's instructions, which is usually indicated and otstupok value, and the recommended operating conditions. If the distances are not listed in the manual, it is necessary to examine the SNP, which gives a reference to the certificate of conformity. Most often, there is a size otstupok, and even depending on the operating mode you choose.
