To heat a small technical building, a potbelly stove is often used, but before installing it, you need to select and equip the design for the output of combustion products. Most often, a chimney is arranged in the garage through the wall.
Chimney device
The design scheme provides for the use of several structural elements: pipes, bends, deflector. This conclusion of the combustion products is simpler, but it can not always be used. The pipe comes out at the level of the outlet of the potbelly stove or at a height of 20-25 cm from the ceiling.
The second option is preferable - when heated from smoke, the pipe turns into a kind of heat exchanger, additionally heating the space. The first type of design involves bringing the element out at the level of the stove. Its vertical part is fixed on the wall on the street. This option is the safest in terms of fire.
Materials and design features
For the manufacture of a chimney for a stove in the garage with your own hands, the following materials are required:
- metal pipes with thick walls (the length and diameter of the product is determined at the design stage);
- a tee equipped with a plug;
- a cap for closing the chimney from ingress of debris or precipitation;
- adapters for connecting the stove to the outlet pipe;
- heat-resistant sealant, material for pipe insulation on the outside, asbestos cord.
The garage is additionally equipped with a ventilation system. In order for the chimney to be resistant to ignition, the following design features are observed:
- Stainless steel chimney is assembled from components. In this case, it is easier to clean and easier to dismantle if there is a breakdown.
- All joints and seams are carefully sealed. For this, an asbestos cord is used.
- If the furnace will be operated frequently and for several hours a day, it is better to divide the structure into 2 parts: a heat exchanger and a smoke exhaust channel.
To avoid smoke in the garage, a tight lock is installed in the pipe. The valve system will allow you to independently adjust the flame power.
Pipe recommendations
The correct chimney for the stove in the garage should effectively remove the products of combustion of fuel. The brick option in this room is not welcome. This design is heavy and bulky. To equip it, you need skill, as well as strengthening the foundation.
Asbestos pipes are difficult to install. They do not withstand high temperatures and already crack at 300 degrees. Products of this type are heavy. They absorb condensate, so their cleaning is difficult.
The best material for making a chimney is stainless steel or corrugation. Corrugated elements are suitable for creating a structure inside a garage. It is easily laid to a tee against a wall or roof. Stainless steel is a universal product that is laid not only inside the garage, but also on the street.
It is better to use alloy steel. It withstands ultra-high temperatures and can last up to 10 years.
Instructions for the construction of the chimney in the garage through the wall
The complexity of constructing a chimney through the wall depends on the characteristics of the building material from which the garage is made, the placement of a stove.You need to prepare for work. Measure the diameter and total length of the pipe. The first parameter should be at least 2 times larger than the volume of the combustion chamber. Otherwise, the traction will be insufficient.
You need to determine the number of parts to connect. So that condensate does not impair smoke output, a method for removing it is provided. For this purpose, a tee is installed. The chimney pipe should rise above the slate and the ridge of the roof by 1.5 m.
The hole for the passage glass is prepared in advance. Here it is necessary to ensure the fire safety of building materials in contact with the pipe. Heat resistant materials are used for this.
Chimney assembly
To equip the hood, all the details must be laid out in the prescribed sequence. This will help to fold the structure correctly. If a stainless steel sheet is used for work, scissors, a pipe bender, and a hammer are required.
Installation of all components
The wall behind the chimney must be lined with heat-resistant material. If the pipe will be discharged through a wooden wall, it is placed in a heat-resistant box, which is filled with glass wool or expanded clay fine fraction.
The passage assembly is fixed not only from the outside, but also from the inside. Next, the pipe nozzle is connected to the bottom of the chimney pipe. For this, a heat-resistant sealant and a special clamp are used. Since the outlet is in the wall, the next element to be installed is the elbow with the desired angle.
After the pipe is brought out onto the street, an element is put on it, which sets the chimney to a vertical position. The outer part is insulated, a protective mushroom is put on the pipe itself. At the bend points, doors are installed for revision and cleaning of the structure.
Since you can make chimneys for bourgeois in garages yourself, the design is not expensive. Before its final fixation, the heating system is checked. During the melting of the potbelly stove, the draft in the chimney should be estimated.
Service and Care Features
Every year, the design is checked for mechanical damage. Every six months cleaning of the garage chimney is required. To this end, brushes or chemicals that dissolve soot are used. The mechanical version is more effective, but unacceptable for a stainless steel. In this case, a hook is permitted.
Before the start of the heating season, the tightness of all chimney connections is checked. To prevent the appearance of soot on the inner walls of the pipe, you can use aspen firewood. Special chemicals that process logs can dissolve soot. For a metal pipe, this method is safe.
If the product has end-to-end damage, it must be replaced. They will reduce draft and smoke into the room.
If you correctly build and operate the chimneys from the profile pipe for the bourgeois, the heating structure will fully perform its functions. It is necessary to observe the rules of operation of the structure.
