Many residents of private houses and cottages use gas heating. Not everyone will decide to independently install such a unit. This work requires responsibility and care. Despite all the difficulties, the installation of a gas wall-mounted boiler can actually be done with your own hands. It is important to follow all the rules set for this.
Who is eligible for this type of job?
According to the law, only specialized employees of gas services have the right to conduct operations with a gas pipeline. But the installation of a gas boiler refers to this type of work that is permissible to carry out independently. However, the connection of such a unit should already be carried out by employees of specialized services.
What needs to be done to install the equipment?
Do-it-yourself installation of wall-mounted gas heating boilers should be done only after certain preparatory steps. First of all, you need to make sure that the room where the boiler will be installed, meets the standards for installation. It is necessary to check the heating device, find out that in all respects it fits the established standards for heating appliances. You should tune in for two business days that the installation will take.
What should be the boiler room?
To install the heating unit , the following rules must be observed.
- Prepare a spacious room. It should be more than four cubic meters in volume. It must be remembered that the volume of the room is directly proportional to the power of the boiler. If you want to put the unit more powerful than before, then you should think about increasing the room in which it will be located.
- An equally important point is the height of the ceilings. The boiler can be installed in a room where the ceilings will be at least two and a half meters.
- Following the installation instructions for a wall-mounted gas boiler, you need to remember that the wall must first be covered with fireproof material. It can be glass wool or plaster.
- According to the rules for installing wall-mounted gas boilers, there must be windows in the room where it will be located. It should be ventilated, and in case of fire hazard it should be possible to open it. If the room is in the basement, then you need to make at least one window.
- According to fire safety rules, the installation of a gas wall-mounted boiler must take place indoors at a height of 800 millimeters or more.
- If you plan to install the boiler, then you definitely need a chimney. It is worthwhile to think over how to connect to it. Installation of chimneys of wall-mounted gas boilers is carried out individually. It all depends on the mounting structure and its parameters.
- The place where the chimney passes through the wall is also sheathed with fireproof material.
- When installing a wall-mounted gas boiler with your own hands, it is necessary to maintain a distance of approximately 300 millimeters with other electrical devices.
General rules for installation
Failure to comply with the installation rules, as well as the continued use of low-quality equipment, threatens consequences for all residents. The owner of the boiler with violations will pay a fine.
Installation of a wall-mounted gas boiler in the house should begin with the arrangement of a high-quality chimney. It is better that the chimney is separate from the ventilation system. This condition is explained by the fact that during the operation of gas equipment a lot of harmful substances are released. They pose a threat to human health, and if you make an extract through the ventilation, then the harmful substances released will end up in living rooms. They will cause serious harm to human health.
Installation of wall-mounted gas heating boilers is carried out after the owner of the house makes sure that the chimney does not have turning angles. If bends appear, then you need to remember that there should not be more than 3 pieces. The pipe has a horizontal part. It is located in the boiler room itself. Its length should not be more than 3 meters.
Wooden house
To complete the installation of a wall-mounted gas boiler in a wooden house, you need to know certain requirements.
- The boiler room is located in one of the rooms or on the ground floor. In a wooden house you can not install a gas boiler in the basement.
- The room must comply with the requirements described in the PPB and sanitary standards.
- Personal protective equipment and fire extinguishing, as well as smoke detectors and fire alarms, are mandatory.
- Do not place equipment in living rooms. Installation in the kitchen, living room is not allowed, installation in the bathroom and toilet is conditionally prohibited.
How high above the roof is a chimney allowed?
In the process of chimney equipment, exclusively refractory materials are usually used. The pipe should rise above the roof by at least 50 centimeters.
Important chimney information
Nowadays, in order to avoid the risks of poisoning people with harmful substances, boilers are equipped with safety equipment: if an accident occurs, the gas supply will be immediately blocked.
The most convenient outlet for the chimney pipe is the roof. There are times when a boiler is installed in a multi-storey building, in which a separate outlet for the pipe is not provided. Then the residents themselves think over the arrangement of the chimney.
In apartment buildings, the pipe is laid through an external wall. A small hole is made. Its diameter is not more than 100 millimeters. For successful operation of heating, it is better to hang the boiler on the same wall.
Each gas boiler is accompanied by instructions. In it, you can read the recommendations for this heater. The diameter of the chimney pipe is usually equal to the diameter of the slit in the body of the gas boiler.
To be able to clean this unit, you should think about where to make the rubber hole in advance, because in order to clean the boiler from debris, you need to open the hatch.
What shape is a chimney worth doing?
According to the installation rules of a gas wall-mounted boiler, it is considered that the cylindrical will become the best form of the chimney. The pipe must be stainless steel. Are bends allowed? There should be no more than three bends in one pipe.
It is important that the connecting part that goes between the boiler and the chimney is approximately 250 millimeters long. If this segment is larger, then defects may occur at the joints.
Installation Recommendations
The design of the gas boiler has its own nuances. They provide a number of installation requirements.
- The distance to the floor should be from 800 millimeters and above. A branch pipe is usually installed at the sink level.
- Do not put anything under a wall-mounted boiler.
- In the room where the boiler is located, it is necessary to close the spaces where the waste from gas equipment falls.
- A metal sheet is usually laid on the floor. It must be durable, square in shape. Its side, as a rule, is 100 centimeters.
- Expansion capacity is placed at the highest point of the system. An air crane is installed next to it.
What you need to check before purchasing a gas boiler?
Before you buy a gas wall-mounted boiler, you need to make sure that it is fully equipped and there are all fasteners. Need to study the instructions. It describes what is included in the equipment kit.
If the fasteners are missing in the kit, then you have to buy them yourself. There is no way to do without them. An important point is the availability of purchase certificates. If there are no such documents, then you will not be able to register a gas boiler. Inside the boiler, a number is placed on one of the sides. It is duplicated in documents. You need to check if the numbers are the same.
In advance, you need to inspect the surface where you are going to attach the gas unit. If the wall decoration has the property to catch fire, then it is necessary to completely cover it with a fireproof coating. Only then can installation work begin. The protective sheet should be a thickness of 2 millimeters or more.
There must be a gap between the boiler and the wall. This distance is allowed from 40 to 50 millimeters. The space must be empty.
Before turning on the equipment, it is necessary to pass water through it through the internal pipes. Due to the pressure of water, all dust and other debris will be washed off.
Installation
Installation of a gas wall-mounted boiler includes several stages:
- Initially, mounting plates are attached to the selected wall. They should be at a distance of 1.5 meters from each other. Perhaps the smallest distance (it will be 100 centimeters). The building level checks how smoothly they were installed. If they are fixed crookedly, then it is better to align them. You can start the installation if you are convinced that the trims hang evenly.
- A special filter is attached to the feed tube. It is designed for hard cleaning. Thanks to filtration, no blockages will appear in the heat exchanger.
- A pipe is installed, which is a chimney. It is necessary to check whether the draft is on. She must be moderate. Combustion products in boilers are eliminated due to the fan installed for this, so strong traction is not necessary. The main point at this stage is the lack of reverse thrust. It definitely should not be when you turn on the device.
- You will need a special threaded sleeve to connect the boiler to the pipeline. From the bottom side, it is necessary to connect a pipe through which water is returned. Water comes from above, also through a special tube. All items of equipment are interconnected by gas welding. The slope should be 0.5 centimeters per meter of pipe.
- It should be noted that the boiler cannot be connected to the gas pipeline itself. Such actions may only be carried out by a qualified gas service worker.
- The last step is to connect the gas equipment to the network.
If you managed to independently install the gas wall-mounted boiler, then you should invite specialists to check the work done.
In which case is it advantageous to put a gas boiler in the apartment?
In apartments, such units are less common than in private houses. Nowadays, there is a tendency to increase heating prices in the cold season, so more and more residents of apartment buildings want to have a gas boiler, so as not to depend on excessive tariffs and to be able to independently regulate the heating temperature of the house in winter.
Now there is a tendency in construction to rent houses with gas heating. Gas equipment will also come in handy when the family does not have extra money, and the local water utility regularly shuts off hot water. You can purchase a simple single-circuit boiler, which is intended for domestic hot water.
At prices, gas units differ from standard boilers for heating water. It is worth considering that installing a counter allows you to pay off this equipment in one or two years.
Bypass unit
There are also double-circuit gas wall boilers. Installation is quite simple. These boilers are recognized as "smart." They determine the temperature in the house, as well as on the street. You can set a program to work that will independently reduce the heating. This is usually done during the day, while all residents are at work or at school. Gas consumption is significantly reduced, in percentage terms it will decrease by 30 percent and a maximum of 70.
But the installation of double-circuit wall-mounted gas boilers is not always relevant. The disadvantage of this heating unit is that it "does not know how to behave" in extreme conditions. For example, when natural disasters occur, the systems in the boiler instantly stall. And the boiler itself goes into minimum heating mode.
What should be considered?
The installation of a gas heating device has rather stringent requirements, but they are caused by safety measures for humans. For example, it is unacceptable to install a gas boiler in the old-style block Khrushchev and if there is no main gas pipeline.
If you do not have time to privatize your home, then there may be difficulties with the boiler: you will not be allowed to install it. In such an apartment you can install only a hot water boiler.
It is not recommended to put a floor gas boiler in the apartment, it is better to give preference to the wall. In a private house, various options for installing a boiler are considered. If the mansion is large, then choose the appropriate unit, which will heat not only residential, but also utility rooms.
Conclusion
So, we found out how to install a gas boiler. The installation of this unit will significantly save on heating costs. At the same time, the performance of the gas boiler is quite high. The room will always be warm and comfortable.
