Installing a gas boiler in a private house - what standards do you need to know about? How to properly install a gas wall-mounted boiler How to properly install a wall-mounted gas boiler

It is not uncommon that many private houses do not have centralized heating and water supply. For this reason, the owners themselves have to resolve such issues. Wall-mounted gas boilers can come to the rescue. How to correctly install a wall-mounted gas boiler with your own hands? How much does it cost to install a gas boiler?

Today they are presented on the market in a huge number and variety of brands. With their choice of problems should not arise. However, it is worth deciding how to mount the boiler - on your own or with the help of qualified specialists? The latter option is not bad, but you have to spend extra money as payment to employees.

The room in which the boiler will be located must have a window for ventilation. The door to the room should open outwards. The room must have an area of more than four square meters. The ceiling should be at a mark of two meters or more. As for the doorway, its width must be at least 800 millimeters. A prerequisite for a boiler room is the presence of a working ventilation duct. Often wall-mounted boilers are located in utility rooms, kitchens or pantries.

Another important condition is pasting the wall where the unit will hang with non-combustible materials. This action will eliminate the possibility of a fire, which can be caused by sparks on combustible materials. Modern non-combustible products will harmoniously fit into the design of the room without spoiling the interior.

When buying a boiler, you need to get an official certificate, because in the absence of this documentation, registration of heating equipment will become almost impossible. Also, the certificate will allow you to connect the equipment to the gas supply system.

Even when choosing a place for the unit, you need to consider installing an exhaust hood for a gas boiler. Old chimneys can be used, and if they are not available, new chimney pipes will need to be installed. Most often, the exhaust system for combustion products comes with the boiler itself.

Compliance with such rules for installing a gas boiler is vital.

Some tips for installing boilers

One of the most important steps in the installation of gas heating boilers is their connection to the gas supply system. In order for the regulatory authorities to give permission for it, it is necessary to carry out the installation and installation of the gas boiler strictly in accordance with the recommendations and requirements that the technical passport has. Otherwise, you will have to redo something, if not everything.

When installing the gas boiler "Navien » , as well as the installation of the Immergaz gas boiler, it is important to check whether its power corresponds to the power of the entire heating system. When connecting the boiler to an old heating system, it is imperative to clean and flush all pipes, which will eliminate the possibility of clogging in the near future.

In advance, it is necessary to think over the entire installation scheme of a wall-mounted gas boiler. It should provide for water treatment to supply the hot water system. The inlet to the unit must be equipped with a cleaning and metal-catching magnetic filter.

One of the worst enemies of a gas boiler, and of the entire heating system, is corrosion. Therefore, in order to avoid its occurrence, it is better to start installing a closed circuit, which will prevent air from freely entering the system.

Installation rules

The wall-mounted gas boiler must be attached to a load-bearing or main wall.
During the installation of the Ariston gas boiler, you need to ensure that the hood and chimney are proportionate.
The unit must be easily accessible so that timely maintenance can be carried out and the replacement of parts freely in case of breakage.
If the boiler is installed inside the cabinet, it is necessary to provide a five-centimeter indent from the cabinet partition above the equipment. This free space will make the nodes in the upper part accessible, so that any maintenance work will become possible.

Boiler installation technology

Before directly installing gas equipment, you need to deal with the chimney hole.

It will be much more convenient to install if you use a special cardboard template. With its help, marks are easily and effortlessly made for all fasteners and the chimney. When the place for the boiler is finally chosen, the template should be attached to the wall. It must have points of fastening lines and places where the wires will connect. These important marks should be transferred to the wall with a marker or colored pencil. The template can then be removed.

The next step is to drill holes for the dowels. To do this, choose a drill that has the desired diameter. Each dowel must be selected according to the material and thickness of the wall. After the holes are ready, metal corners are attached to the wall.

Then you need to remove the top cover of the unit. Now you can safely hook the equipment to hanging corners on the wall. Before installing the brackets, you need to make sure that all chimney fittings have the right dimensions exactly according to the instructions, otherwise there will be problems later. The bracket to which the gas boiler is attached must itself be very securely fixed to the wall. This is the most important point.

It is important to remember that depending on the type of wall, there are different ways of fastening. There are different types of mounting installations, each of which is designed to install a certain type of unit and type of load.

During installation, it is important to ensure that debris does not get inside the fan. The branch pipe, through which combustion products will be removed, must recede from the wall surface by at least two centimeters.

Boiler mounting tools

Before installing the wall-mounted unit, you should acquire in advance:

screwdrivers,
fasteners,
glue,
tow,
wrenches,
drill,
gloves
threaded socket,
non-combustible finishing material.

First you need to turn off the water supply using the valve. After that, you can connect the boiler and the pipeline using a threaded coupling. To achieve the most dense fixation, it is imperative to use tow. Connect the unit first from the end side. The hot water supply is connected to the top pipe of the unit, and the return is connected to the bottom pipe.

The junction box of the unit must be connected to the power supply cable, and a safety contact outlet must be provided from the switch.

Thanks to the cable, power is supplied to a powerful boiler, and therefore each fuse must not exceed three Amperes in power, or the fuse must have a rating less than the current rating required for the boiler to be used efficiently. At the end of this type of work, you need to connect the gas equipment to a reliable ground.

As you can see, installing a gas boiler on your own is quite feasible in the shortest possible time without wasting time, effort and money. Do-it-yourself installation of a wall-mounted gas boiler on the video can be studied in more detail. For example, the most frequent questions were regarding the installation of the Danko gas boiler, which is gaining popularity.

The cost of installing a gas boiler is much lower than the price of calling specialists. In addition, the work is carried out quickly, and the skills gained during installation will still be useful in the future.

Gas heating is considered the cheapest today and also the most efficient. This can explain the fact that gas boiler manufacturers offer their customers the widest range of their products. A gas boiler can be selected in different capacities based on the total area of \u200b\u200bthe house, as well as in various sizes to be placed in a room specially designated for it. It depends on how correctly the installation of gas heating boilers is carried out, how efficiently the heating system will work and how economical the boiler will be.

Requirements for the installation of a gas boiler

The first nuance that you should pay attention to is that the installation of gas heating boilers must be carried out in a non-residential premises. Some wonder if it is possible to install a boiler in a bathroom or kitchen. The answer to this question depends on whether it will be possible to arrange the removal of combustion products from such a room. The chimney must be installed in such a way that it does not interfere with the passage and complies with all fire safety regulations. In the boiler room, it is necessary to equip a system of supply-flow ventilation. Air should exit through holes under the ceiling, and enter through holes that are located above the floor, but not higher than 30 cm.

For a private or country house with a small area, a boiler with a capacity of 20-30 kW is ideal. To install such a boiler, then connect the heating to a gas boiler, you will need a room with a volume of no more than 7.5 cubic meters. If the boiler is planned to be installed in the kitchen, then such a room must have an area of \u200b\u200bat least 12 square meters. meters.

How to install a gas boiler in the bathroom

To install a gas heating boiler in a room of this type, one of the following conditions must be met:

The presence of a window in the bathroom;
Install a boiler with an open or closed combustion chamber.

For a boiler with a closed type combustion chamber, you can also choose a room without a window. Typically, such boilers are equipped with a chimney, which serves as a channel for the penetration of oxygen.

In the case of installing a boiler with an open type combustion chamber, a window will be a must. If the boiler has an open combustion chamber, and there is no window, but you still want to install it in the bathroom, then there will be nothing left but to cut through the window. If this is not done, then the utilities and housing services simply will not issue you permission to install and connect gas heating boilers.

Particular attention should be paid to the wiring of the gas unit. Modern devices are equipped with various components of automation and electronics. Wiring must provide a good and reliable drive. The wires must be very well insulated, as there is always high humidity in the bathroom.

If you are not sure that you can perform these procedures yourself, it is better not to take risks and contact a specialist in this field.

How to install a boiler in the kitchen

The kitchen is one of the most optimal rooms for installing a gas boiler, and there are several reasons for this:

The first reason is that the kitchen meets all safety requirements and standards.
Secondly, every kitchen has a window, and sometimes several. Also, the window usually has a window, and this is an important detail for airing the room.
Another reason is that the kitchen has ventilation.
Usually the walls of the kitchen are built from materials that do not have the ability to ignite. Even if the walls are made of a different type of material, it will be sufficient to install a gas heating boiler based on fire safety rules.

Installing a floor boiler

Gas boilers are divided into several varieties, and the main criterion for separation is the method of installation. Manufacturers of modern boilers offer their customers wall-mounted and floor-mounted boilers.

The floor boiler stands out for its simpler installation. To install such a boiler, you will need to organize a podium from a metal sheet or concrete mortar. The most important condition is to make a solid foundation and use non-combustible material for this.

The only disadvantage of such boilers is that they require more free space than for wall-mounted devices.

Manufacturers of gas boilers recommend using a separate room in the house for floor-standing devices. This will not only comply with safety rules, but the boiler will not interfere with the passage. From a separate room, you can organize a boiler room. Here you can also install other components and components of the heating system.

Installation of such a system begins with the most important element - the boiler. After that, you need to attach a chimney to it. After installing the chimney, the piping of the gas heating boiler follows. For the correct implementation of this, there is a piping scheme for a gas heating boiler. The last step is to connect the device to the gas and water pipes.

Installation of a wall-mounted boiler

The installation of gas heating boilers of this type requires care when installing fasteners that are fixed on one of the walls of the room. Such a boiler is very popular with owners of private or country houses, as it is light in weight and compact in size.

During the installation of such a boiler, it is also necessary to follow certain rules and safety measures.

If the house is built from a material such as wood, then the wall on which the boiler will be installed must be covered with a sheet of non-combustible material, such as metal. Often in private homes, a wall-mounted gas boiler is mounted in the kitchen. Modern devices have an attractive appearance, so they will fit into any interior and will be combined with kitchen furniture.

A wall-mounted gas boiler does not require a separate boiler room, as it includes all components and components, such as a circulation pump, shutoff equipment, automation, and others. You will need to carry out such a stage as distributing heating from a gas boiler.

Installation of a gas boiler, wall or floor type, connection and piping of elements such as gas heating boilers, repairs - all this is best entrusted to a specialist.

This will help to avoid errors that can affect the efficiency of the heating system. If you do the installation yourself, then you need to have certain skills and knowledge, and also take as a basis all the requirements that are indicated by SNiP. Otherwise, the system simply will not be approved by the state services and it will require repair of gas heating boilers.

Natural gas is the most convenient and affordable type of fuel for heating boilers in private houses. The pipeline system for supplying gaseous fuel to the burner, simple ignition, parameter control and shutdown make the operation of gas heating installations simple and does not require special training. The ability to immediately stop burning in emergency situations provides an increased level of safety during the operation of installed equipment.

At the same time, there are special requirements for installing a gas boiler in a private house. Their implementation is mandatory for all types of equipment in order to ensure a minimum degree of risk when burning explosive fuel in residential buildings and individual structures.

Requirements for rooms and air exchange

An important advantage of a private house, unlike city apartments, is the possibility of allocating non-residential premises for the installation of heating equipment. The current regulatory documents provide a number of requirements for the size and arrangement of such rooms. The main ones are:

a total area of 4 m 2 or more should allow the boiler to be placed at a distance of 350 mm from the outer wall;
ceiling height of at least 2.5 meters;
the floor level in the furnace is not lower than the zero mark of the building;
the width of the entrance door is from 800 mm, while the leaf must open outward;
obligatory presence of a glazed window, the area of \u200b\u200bwhich is determined depending on the thermal performance of the gas boiler;
the illumination rate is set to 0.03 l/m 2 ;
the minimum cross-sectional area of the air channel for natural supply ventilation is 8 cm 2 for each kW of heating unit power.

When organizing the air supply, it is necessary to take into account its amount used for gas combustion and also add a three-fold air exchange according to the volume of the room.

All walls and internal partitions must be built of non-combustible refractory materials with a fire resistance rating of at least 45 minutes. The layout of the room and the arrangement of ventilation ducts should not contribute to the spread of flame in case of fire.

The volume of free space not occupied by the installed equipment is normalized depending on the capacity of the installed boilers:

for heating units up to 30 kW - less than 7.5 m 3;
60 kW - 13.5 m 3;
more than 60 kW - 15 m 3.

Installation of a gas boiler in a private house with a total heat output of more than 200 kW is prohibited. In this case, the power of one unit should not exceed 100 kW.

Flue gas removal

Channels and pipes designed to remove gas combustion products must ensure normal combustion in the boiler furnace. Concerning:

the cross section of the flue duct must not be less than the size of the boiler connection pipe;
it is allowed to reduce the cross-sectional area of the chimney if the design of the heating unit provides for the forced removal of combustion products and air supply;
channels can be located inside the main walls and partitions of the appropriate thickness or be attached to them;
the material for the manufacture of chimneys must be fireproof and not subject to active corrosion;
the design of the chimney should provide for the presence of a special hatch for cleaning the channel from soot and a device for draining the resulting condensate;
the height of the chimney above the roof ridge or the line at an angle of 15° away from it.

All butt joints of the elements are made airtight and exclude not only the release of combustion products into the premises, but also the possibility of air leaks and a decrease in thrust.

Preparatory activities

Preparation for the installation of a gas boiler in a private house begins with the study of regulatory requirements, the rules for installing a gas boiler in a private house, design solutions for the placement of auxiliary equipment, technical specifications and the internal structure of the boiler.

For permission to connect a heating boiler to a gas pipeline and supply gaseous supply to a residential building, the building owner must submit a corresponding application to the local gas service, where the request will be considered by specialists within a month.

After that, the applicant is given technical conditions for connection or a reasoned refusal until the existing comments are completely eliminated. Installing a gas boiler without obtaining and fulfilling technical conditions is considered illegal and may entail liability for the owner of the house, the level of which is determined by the consequences of the deed.

The project of an individual furnace is developed taking into account all the technical requirements and rules set out in the conditions. The heat losses of the building are calculated and the boiler capacity is determined, taking into account the consumption of hot water for household needs.

The finished project must be approved by the special supervision service of the gas supply organization. To do this, together with it, the following is sent to the supervisory authority:

technical passport of the boiler;
manufacturer's instructions for installation and operation of the heating unit;
a copy of the certificate for its compliance with current regulatory documents.

The next stage of work is to complete the equipment and necessary materials. Here you should pay attention to the correspondence of the connecting fittings in size and thread pitch to the counterpart connections of the boiler, pumps, tanks and other equipment provided for by the design solutions.

It must be understood that the furnace equipment is part of the heating system and should not be considered as a separate isolated section of the house.

Installation of boilers in houses of individual development

The method of placing a heating boiler in a residential building depends on its design and can be floor or wall. It should be noted that floor models in most cases exceed the heat output of mounted heat sources.

In addition, a freer circuit of the coolant circulation in such devices allows their installation for operation in autonomous heating systems with natural circulation.

Installation of floor boilers in a separate furnace

If it is necessary to install a heat source with a power of more than 32 kW, gas boilers with installation on the floor are chosen, since the thermal performance of serial mounted models does not exceed the named value. The developed typical schemes of furnaces, for private houses, provide for the presence of:

expansion tank;
domestic hot water heater;
capacitive or high-speed separator;
distribution comb;
at least two circulation pumps.

In addition, it is required to install emergency relief lines and safety valves that operate when the pressure in the pipelines rises.

Work on the installation of the boiler begins with the preparation of brick or concrete bases not only for it, but also for all tanks, which, after filling with water, will become quite heavy. After that, it is necessary to assemble the distribution manifolds and pumping units with shut-off valves, and fix them on the wall according to the design scheme.

Boiler piping

Install the tanks and the boiler on the bases and, if there are mounting holes, fix the position with anchor bolts. Now you can start work on the device of the chimney and installation of pipelines.

One of the circulation pumps is installed on the return line between the boiler and the separator. The second one is on the supply line after mixing the coolant flows in the separation column. A safety relief valve must be installed on the outlet line of the heated water from the boiler, which will ensure the protection of the installed equipment in case of pressure increase.

Return.

Emergency discharge pipes must not be connected to household plastic sewers, which may be damaged by boiling water. Metal must be used as the material. At the connection to the water supply, a regulator for feeding the heating system is installed, which in a simple version is a bypass valve that regulates pressure after itself.

The length of the horizontal section of the chimney at the outlet should not be more than two diameters of the factory branch pipe. After that, the chimney must be moved to a vertical or inclined position at an angle of at least 30°. If the temperature of the flue gases exceeds 85 ° in the passport data of the unit, the metal chimneys must be closed with thermal insulation.

Connecting a gas boiler in a private house to a gas pipeline, purging a fuel line and a test run of gas is carried out by employees of a gas supply organization. These works are allowed to be carried out by the installation organization, but only in the presence of a representative of the controlling office.

Installation of wall hung boilers

Unlike floor structures, mounted models do not require such complex piping and installation of auxiliary equipment. A circulation pump, an expansion tank, a heat exchanger for heating domestic hot water and a safety valve are already installed inside the unit's body, which, according to the device, is a compact mini-furnace.

However, the power of such boilers usually does not exceed 32 kW, which can ensure the operation of the heating system in a residential building up to 300 m 2. At the same time, if we take into account the consumption of hot water in double-circuit devices, then the heated area must be reduced by 25-40%. But for small buildings, wall-mounted gas boilers are the most optimal solution to the issue of organizing stable heating operation.

Boiler location

There are two types of mounted gas boilers on the market, which differ in the way they organize the supply of air for combustion and the removal of flue gases. They are called boilers with atmospheric and closed firebox. In the second case, the design of the unit provides for the presence of an axial exhaust fan and a double coaxial chimney. The piping of both types is structurally the same.

Coaxial chimney.

The place for installing the boiler is chosen depending on its design. Models with an atmospheric firebox should be mounted as close as possible to a vertical smoke channel that runs inside the wall. Units with a closed firebox can only be installed on an outer wall or on a partition adjacent to it in order to be able to bring the coaxial pipe to the street.

Brief installation instructions

In each package, manufacturers include an assembly or marking sheet, on which the contours of the boiler are drawn, marking all connections and installation points for fasteners. Its presence greatly simplifies the work. The installation procedure is as follows:

fasten a sheet of refractory material with a thickness of at least 3 mm to the wall surface;
on the surface of the sheet you need to stick the mounting sheet;
drill holes in the mounting marks and install anchor hooks on which the heating unit will be hung;
hang the boiler on the wall;
check the gap between the boiler and the wall, if necessary, remove the device and tighten or unscrew the fasteners;
focusing on the applied markup of the mounting sheet, connect the gas boiler to the heating and hot water supply system;
install the flue on the outlet pipe and bring it to the smoke channel or take it outside;
connect the boiler to the mains through a voltage stabilizer or uninterruptible power supply;
invite gas service workers and, in their presence, connect the unit to the gas pipeline.

Normal operation of heating attachments can only be ensured if the power supply is stable. Even short-term failures will lead to a stoppage of the boiler and possible damage to the electronic control unit. Therefore, protection is a must.

Rules for the operation and maintenance of a gas boiler

The operation of heating equipment should be carried out at a positive air temperature and normal humidity. At least twice a year, it is necessary to check the cleanliness and performance of the ventilation system and chimneys. The main activities during the operation of the boiler must necessarily include:

annual cleaning of all installed filters;
control of technical serviceability of the control unit;
inspection of the heat exchanger for the presence of soot;
checking the tightness of the joints and connections of the gas pipeline by soaping;
cleaning the burner from soot and dust.

All failed parts should be replaced with new ones, and not attempted to be restored. A conscientious attitude to the implementation of all necessary technical measures will increase the life of the equipment and ensure your safety.

basic information

In most cases, there are units that are able to heat 6 liters of water in one minute. This indicator can be considered quite good. True, it is possible only if the correct installation of the installation is carried out.

The principle of operation is based on the presence of two separate circuits. The first is responsible for heating the house, and the second for hot water in the tap.

To connect the installed boiler, you need to take into account the presence of several systems in the room at once:

Heating. There will be two pipes - hot supply and cold reception.
Water pipes. Cold water is supplied to the system.
Gas pipeline. Fuel supply.
Power supply. It is necessary if the device has control devices and automatic ignition.

Installation and connection of the double-circuit begins with mounting it on the wall. For this, special brackets are used, which in most cases are supplied with the equipment. The main thing to consider is that the fasteners must be in an ideal horizontal plane, and therefore it is imperative to have a level.

After installing the fasteners, the boiler itself is hung on the wall. All this is done by hand. In order to avoid any mistake, just in case, you can first watch several videos, of which there are many on the network. They show the installation of different systems.

Requirements for the premises

There are several rules that must be followed when choosing a room for installing the unit:

The presence of a window that can open at any time.
Active ventilation.
The room must have outlets for all the necessary pipelines to which the domestic boiler will be connected. Particular attention should be paid to the gas pipe. It must have a counter.

Usually the connection of similar devices is the same. The only thing that can differ is the location of the nozzles. But that doesn't happen often either.

Main knots

Due to the fact that there are many different models of gas boilers on the market, it is difficult to talk about all the specific installation schemes. You can only highlight the main components that must be present so that the unit is not only easy to install, but also used in the future.

Key points:

Water filter. Mandatory element of a gas boiler in a private house, which will help protect the system from debris generated in the pipes. Another such device is installed on the return line to stop possible contamination from the heating system. It must be placed on a horizontal section along with a crane.
Magnetic filter with tap. Used to fight rust and scale.
Gas filter with tap. Allows you to protect the installed boiler from scale and dust. The use of this element allows you to significantly increase the service life of the installation.
Ball valves, which are needed to shut off highways, so that it is easier to carry out repair work.
A special expansion tank is installed for the heating system. In wall models of boilers, they are usually installed at the factory.
Safety devices -. Again, wall models already have it all. For floor-standing, everything is purchased separately and placed next to the installation.
Radiators.
Pipeline.

Important nuances

Installation must begin with the installation of a shut-off valve and a filter on the water supply. This will help to pass through the unit only purified liquid, which in turn will significantly extend the service life.

The valve is necessary for a situation when it is necessary to turn off the water supply for filter replacement, system cleaning or repair.

After that, the pipes of the heating system and hot water are connected. There is nothing complicated here either. First, the shut-off valves are connected, and then the connection with the boiler takes place.

A home wall-mounted boiler is necessarily equipped with a pump that ensures uniform heating of all radiators in the room. This device needs special strapping. Wall models are volatile, and therefore any power outage instantly reduces work efficiency. Floor models are able to work without such pumps, since special elements are provided for them to create natural pressure.
