How to connect a gas water heater to a water supply. How to install a gas water heater with your own hands

Gas water heaters are considered one of the cheapest ways to solve hot water supply problems. This equipment is installed in most private homes. If the house is old, most likely there is an old-style water heater installed here, which can be not only ineffective, but also dangerous. a newer one will allow you to prepare hot water as cheaply as possible. With the new device you don’t have to worry about safety, and it’s very convenient to use.

Standards and requirements that govern the installation of geysers in apartments

Having decided on a replacement, the first thing you should do is familiarize yourself with the rules for installing geysers in apartments and houses. Issues regarding the installation and connection of these units are covered in SNiP. The document is called “Gas distribution systems”, and its number is 01/42/2002. If distribution systems or internal wiring were made on the basis of polymer pipes, then in addition to this document there is another one - SP 42-101-2003. These are “general provisions for the design and construction of gas distribution systems made of metal and polyethylene pipes.”

The main requirement for replacing geysers in an apartment, which is described in SNiPs, states that any work related to the organization of gas supply can only be carried out by specially trained people from gas facilities or private organizations. The latter must have a license for these works. By law, any independent changes can lead to explosions. Also, independent work is punishable by serious fines.

The pressure in the water supply system must be no less than 0.1 atmospheres. The speaker should be mounted on a wall that is lined with non-flammable materials. It cannot be closer than ten centimeters to the stove or above it. This is strictly prohibited.

Do I need to register?

Replacing a gas water heater with a new one is not specially formalized. But if a new one was installed where there was no water heater before, then official projects would need to be developed. They are ordered from gas utilities or companies licensed for such work. Any installation work is prohibited until the project is approved.

If the column has already been installed before

When replacing due to a malfunction, not only the unit itself, but also its passport should be changed. If you perform the installation yourself, the passport of the new dispenser will not include a note about putting the device into operation and inspections.

In accordance with fire safety requirements in residential buildings, gas equipment is inspected annually. It will not be possible to hide a gas water heater yourself from specialists. In this case, the equipment will be forcibly turned off, and the pipe will be sealed.

After the notice is received, you will have to reinstall the water heater. But this is done with the involvement of certified companies and specialists. They will conduct a study of the ventilation ducts. In old buildings, the channels are often clogged with various debris. Operation of such passages can be dangerous.

What are the dangers of self-installation?

Even if an old gas water heater is replaced with a new one, this is not a guarantee that everything will be fine. If during installation a gas pipe was inserted past the meter, then this falls under an article of the administrative code. There is a fine for this.

In addition to the provision of administrative penalties, there is also an article from the law “On Fire Safety”. According to it, the owner of the property may even incur criminal liability (depending on the severity of the consequences).

Materials and tools

To replace a gas water heater, you will need a hammer drill with a concrete drill. You should also prepare a set of open-end wrenches for 27/30 and 32/36, a gas pipe wrench, sealant, and FUM tape.

In addition to the speaker, you should purchase an outlet. This is a decorative element used to decorate the chimney inlet on the wall. You need an oblique water filter. Alternatively, you can buy a water softening system. To connect the water heater to the water supply system, various bends, tees, hoses, and taps are purchased. Experts advise purchasing flexible wiring. It is easier to work with due to the absence of the need to seal connections.

To connect to the gas main you will need a gas hose. It must be of sufficient length and have a thread for connection to the gas unit. It is worth making sure that the thread on the hose matches the one on the column. To connect the latter to the chimney, buy a galvanized pipe with a wall thickness of at least one millimeter. Such requirements are due to high gas temperatures. Thin-walled pipes burn out quickly.

Removing the old heater

First of all, turn off the gas supply valve to the column. Next, use a wrench to unscrew the nut that holds the gas hose to the column pipe. The hose should be carefully inspected. If it is worn or damaged, it is better to replace it.

Before disconnecting the device from the water supply system, it is recommended to close the rack valve. In the absence of the latter, shut off the valve at the entrance to the apartment. Pipes and flexible wiring are disconnected using wrenches. All that remains is to disconnect the pipe connected to the chimney. After this, the device can be safely removed from the wall.

On some dispensers, the gas supply may be in the form of a steel pipe. The coupling that connects the pipe and the pipe is difficult to unscrew. If you apply too much force, you can ruin the pipe. The clutch does not rotate well due to paint. First, remove the paint layer and then unscrew the coupling.

Installation of a new heater

Replacing a gas one should begin with the installation of fasteners. They are screwed using standard dowels. The location for the column is chosen based on the requirements of SNiPs.

When a suitable place is found, holes are marked on the wall. They must be strictly horizontal. This can be checked using a building level. Next, holes are made according to the markings. If there is tile on the wall, then you should purchase a separate drill for it.

Once the tiles have been penetrated, install a regular concrete drill. You can turn on the impact mode on a drill or hammer drill. After the holes are ready, screw in the dowels. The entire mounting kit is hung on the latter. Connection is the most important step when replacing a gas water heater. Mistakes are not allowed here. We will look at how to connect the unit to water and gas.

Connection to water supply

To do this, a tee is cut into the pipe with cold water. A filter, shut-off valve and other devices are screwed to the latter. This is relevant for installing a column for the first time - when replacing, there is already a tee in the pipe. Then a hose is attached to it, which at its other end is connected to the inlet pipe on the heater. It is worth doing this carefully so as not to confuse the inlet and outlet pipes.

The output is marked in blue and the exit is marked in red. The outlet element is usually connected to the tee and faucet through a hose that is connected to the hot line.

Final stage: connecting to gas

When connecting to gas yourself, do not tighten the nuts too much. This can easily crush the gaskets inside the hoses. After installing and tightening all the nuts, cover both ends of the hose with soapy foam and open the gas valve. If bubbles start to grow, there are leaks. The nuts are tightened. This is repeated until all leaks are eliminated.

How much does it cost to install a geyser? Dismantling and replacing a geyser by the hands of specialists will cost an average of 3,000 to 4,500 rubles. This is in Moscow, in the regions it will be cheaper. The amount is not astronomical, but, nevertheless, it is still a pity to give it for work that you can easily do yourself. And everything would be fine, but in this matter there are a great many nuances, ignoring which can greatly hit the user’s pocket.

What are these nuances? What kind of rules and regulations generally govern these types of work? And you simply must know the basic provisions, because this is not a plumbing system with which you can experiment. Gas is gas, negligence and carelessness in dealing with it ends very badly. In this article we will look at the procedure for replacing and installing a gas water heater. Let's look at step by step how and what you can do yourself, and what is best left to a gas industry representative.

Standards and requirements governing the installation of a geyser

Note! Let’s immediately make a reservation that all types of work related to gas supply, i.e. supplying a gas pipe, installing tees, shut-off valves on the gas pipe, etc. carried out only by organizations that have the appropriate special license. Ignoring this provision will, at best, lead to a hefty fine and a severe headache.

All work on installing a geyser can be divided into two categories:

installation from scratch, i.e. it wasn’t there, but you decided to deliver it;
replacing the old column with a new one.

In the first case, a design and supply of a gas pipe to the location of the future water heater is required. All this work is the responsibility of the gas industry in your area or a company that has a license for the corresponding type of activity. It is impossible to do without this. Do not try to do anything yourself in this case. This is not smart, because... You yourself risk your life and property, and when installing a gas water heater in an apartment, you endanger other people. And it’s not easy to play such games with the state, it’s not the right weight category. Therefore, entrust this work to people authorized by law for this type of activity.

If the project is ready, everything is agreed, then by completing part of the work properly you can save a significant amount. Any work that you decide to carry out yourself must be carried out strictly in accordance with the requirements of the approved project; if this is not done, the gas industry will not accept this gas water heater for operation.

Note. All work on the installation of gas units begins only when you receive a project with all the necessary permits and approvals.

All standards for installing a geyser are regulated by the following acts:

SP 42-101-2003 "General provisions for the design and construction of gas distribution systems made of metal and polyethylene pipes"

SNiP 42-01-2002 GAS DISTRIBUTION SYSTEMS

In order to bore the reader with many clever words, we present the basic standards for installing a gas water heater, which apply to the intended installation location:

The room in which the column is installed must have a volume of at least 7.5 m3.
The room must have ventilation (vent, window, etc.).
The ceiling height in such a room must be at least 2 m.
The room must have a chimney with a diameter of at least 120 mm (at the same time, “smotherers” in apartments do not qualify as such).
The pressure in the water supply must be at least 0.1 atmosphere.
It is prohibited to install geysers in bathrooms.
The column is installed on a wall made of non-combustible materials; installation above a gas stove and at a distance closer than 10 cm to it is prohibited.

At the same time, those speakers that are installed in bathrooms, in accordance with the technical standards in force at the time of installation, are allowed to be used in the future. That is, the law does not clearly prohibit its further exploitation. This means that replacement with a new one does not prohibit. And does not require transfer at the user's expense.

If all these requirements for installing a geyser are feasible, then you can order a project. The exact installation location and other details will be displayed in the project.

Removing the old column

Since the basic requirements and standards have been reviewed in general terms, if everything complies, you can begin replacing the gas water heater. And we should start with dismantling. You can do this yourself and save from 300 to 800 rubles.

We start by shutting off gas access to the column by closing the tap at the end of the gas pipe. Using an adjustable wrench or an open-end wrench of the appropriate size, unscrew the fixing nut of the hose (rarely, but there is a method of supplying gas using a metal pipe). It is quite difficult to damage the gas pipe when unscrewing the hose, but with the “ancient” connection method, i.e. a piece of metal pipe, quite realistic. Especially if the joint has been painted over for years. In this case, do not use excessive force; to remove paint, use a modern solvent specifically for this work. When unscrewing, hold the gas pipe with a second adjustable wrench, this way there is less chance of damage.

After disconnecting from the gas pipe, it is necessary to remove the hose (pipe) from the point of entry into the column. If the hose has recently been changed and its condition is satisfactory, then it can be reused when connecting a new column. If you have any doubts about the reliability of the hose, purchase a new one. When purchasing, take a certified and tested hose; after all, this is gas and buying a cheap hose from an unknown manufacturer is not appropriate here.

The next dismantling step is to turn off the water supply system. If there are taps to turn off the column, turn them off. If this is not possible, shut off the supply to the apartment. In the case of the latter option, before installing a new column, purchase two taps for the inlet and outlet of water from the column and install them on the pipes in the place where the connection will be made. This will make it easier to maintain in the future.

After disconnecting the column from the water supply, remove the connecting pipe from the outlet of the column and remove it from the chimney. The speaker is disabled and can now be removed from the wall mount. The installation site is free, you can begin installing the new unit.

Installation and commissioning of a gas water heater

During the initial installation, it is better to entrust the connection and verification, with the registration certificate of the gas water heater, to the gas specialists. If you change the old column, you can do all the work yourself. But there are two nuances, if you doubt your ability to correctly install a gas water heater - trust the specialists, your wallet will be somewhat thinner - but the nervous system will remain unaffected and, ultimately, the benefit will be yours.

If you decide to do everything yourself, you will succeed, the main thing is to do everything slowly and progressively. But even in this case, you cannot do without a representative of the gas industry; he must register the dispenser. The best option, perhaps, is the situation when you do all the connection work yourself, with the exception of gas-related work. In this case, you will save a significant amount and there should be no problems with the gas service, because connection to the gas main will be carried out by their representative. We will consider this option.

Tools and materials

Before starting work, you must purchase and have the following materials:

Galvanized pipe or corrugation, no thinner than 1 mm. If it comes with a speaker, great. If not, measure the diameter of the outlet of the column boiler or look in the instructions and purchase the appropriate pipe.
Purchase a ring-socket for arranging the entrance to the chimney, also according to the size of the corrugation.
If you plan to install a gas water heater in your house and you need chimney equipment, you will need an asbestos or metal pipe with a diameter of at least 120 mm, or more. The length is at least 2 meters, more is possible - the traction will be better.

The gas hose is standard, the size of the hose will depend on your conditions, i.e. distance from the end of the gas pipe to the inlet into the column. Pay attention to the type of thread at the inlet to the column, the hose tip must be suitable, there must be a match in the type of thread external/internal and a diameter of ½" or ¾". The diameter of the fixing nut on the hose is ½" and if the inlet to the column is ¾" you will need an adapter (coupling).

It is better to prepare the water supply connection point in advance, so you only need two connecting hoses of the required length. You can make connections using metal-plastic pipes, whichever is more convenient for you. In the latter case, determine whether couplings are needed to match the dimensions of the pipe and the connection location and thread (external/internal).
Dowels for mounting the speaker on the wall.
If your home does not have a coarse filter installed, we recommend installing one. The service life of the new unit will directly depend on the quality of the water.

Tools you will need:

Depending on the complexity of the work and the material - a hammer drill with a set of drills and chisels, a drill with a drill for ceramic tiles.
Adjustable wrench (2 pcs.).
Open-end wrenches 27/30 and 32/36.
Tow and sealant type "Unipak".

Installation and testing of a new unit

This description assumes that the water supply and the presence of a chimney have already been implemented. At the location where the gas water heater is installed, mark the points for installing the fasteners. You must calculate the height of the column in such a way that the connecting pipe (corrugation) has a vertical length from the outlet of the column to the socket of at least 50 cm, if the room height exceeds 2.7 m - 25 cm. At the same time, the installation height of the geyser is not should give children free access to the device. Also measure the distance between the mounting holes on the speaker body. After you calculate the installation locations for the dowels using a hammer drill or drill, depending on your conditions, make holes and install hooks. The speaker can be hung on the wall.

Now, using connecting hoses or PVC pipes, we connect the water supply to the inlet and outlet of the column. Using a hose is convenient because it does not require tow or FUM tape at the joints. We connect the cold water tap in series with the gas water heater inlet, indicated in blue. In the same way, we connect the hot water outlet to the tap (indicated in red). We open the cold and hot water tap and see if everything is sealed. If a leak is detected, carefully tighten the hose fixing nuts. Without unnecessary efforts, as you can crush the rubber gasket - seal. The connection using pipes will need to be unscrewed in places of leakage and the tow with a sealant or FUM tape must be twisted.

After we achieve the tightness of the water supply, you can go in two ways: either call a gas technician, or install the gas water heater yourself in full. You decide.

If the second option, then take a gas hose and screw it to the gas tap. After this, connect the other end of the hose to the inlet in the column. We clamp without unnecessary effort, so as not to crush the paranitic gaskets. We take a soap solution, generously smear the joints around the entire perimeter, open the gas supply tap and carefully observe to see if there are any bubbles. If there is, press the nut a little and apply it again. So until we achieve complete tightness.

So, we have a sealed connection between water supply and gas. The next step is to install the corrugation. Here everything is much simpler, on the one hand we put the speakers on the outlet, on the other we insert them into the chimney socket.

We insert the batteries into the column, open the hot water tap and adjust the water temperature according to the operating instructions for the column. We use it.

And one last thing. Usually, large stores also have a connection service. When purchasing, ask how much it will cost to connect them to a specialist. It will be cheaper or even free, and there will be no issues with the warranty on the column at all. And registration in the gas industry will take place without unnecessary friction.

If this is not available, I still recommend that you entrust the connection of the gas hose to a gas installer (the cost of installing a gas water heater for such a connection is several times less than for complete dismantling and installation), and he will be pleased (he will earn money) and there will be no complaints against you. Plus a guarantee of safety and integrity. But it is, of course, up to you to decide.

When deciding which water heater is better, most often the choice is gas. These devices are distinguished by their reliability, as well as the ability to heat a large volume of water in real time due to their flow-through type. But, when installing a flow-through geyser in an apartment or private house, certain rules must be followed.

It is impossible to do all the work on connecting the speaker yourself. There are installation standards, according to which only a gas service or an organization that has the appropriate license has the right to design and install gas equipment. Simply put, connecting the device to the gas main with your own hands is prohibited. But you have the right to carry out all other work yourself.

Before installing a gas water heater, you will need to order design documentation for the installation and connection of the equipment. Preparing the documentation will take some time, which can be used to select a water heater model.

The need to install a gas water heater arises for three reasons.

If the gas service insists on moving the unit to another room. Usually this moving the device from the bathroom to the kitchen, since it was previously installed according to currently outdated standards.
In the case when it is necessary to replace a failed gas water heater, or replace an outdated unit with a new one, placing it in the same place.
You have expressed a desire to install a water heater for the first time, instead of other types of hot water supply. In this case, a gas line must be installed in the house.

The choice of unit must be taken with particular seriousness, since the installation of a geyser in an apartment in which the kitchen does not have a chimney duct built into the wall (not to be confused with a ventilation duct) is not permitted according to regulations. The way out of this situation is to purchase a speaker that has closed combustion chamber. In such a unit, a coaxial pipe is used as a chimney, which is led out through the wall. The engineer performing the project must notify you of this situation.

Very often, a closed geyser is installed in a private home, which is due to its fairly simple installation.

Choosing an installation location

Despite the fact that the installation location will be determined by the prepared project, those who want to have a water heater in their kitchen must know the rules for installing a gas water heater in an apartment.

Dismantling the old unit

Before replacing the gas water heater with a new one, you must remove the outdated or broken unit from the wall:

You should start by turning off the gas supply to the device by closing the corresponding valve. After this, using an open-end or adjustable wrench, unscrew the nut on the pipe or hose through which gas is supplied to the device. If the nut on the pipe cannot be easily unscrewed because it has been painted over for a long time, then you should use a special solvent to remove it. After this, you need to hold the gas pipe with one adjustable wrench and unscrew the nut with the other.
The next step is to disconnect the device from the water supply. If, near a previously installed unit, it was not installed water shut-off valve, then it will have to be turned off with the main tap in the entire apartment. But before you connect water to the new column, do not forget to install 2 taps (one at the inlet to the unit, and the other at the outlet pipe). This will greatly facilitate the maintenance of the water heater in the future.
At the next stage, you will need to remove the pipe connecting the column to the chimney and unscrew all the fasteners holding the device to the wall.

Installing a new device

If you are installing a water heater indoors for the first time, then in order to install it correctly, it is better to entrust all the work to the employees of the relevant service. In case of replacing a previously installed device, it is allowed to install the geyser yourself. But still, you cannot do without the involvement of gas workers when connecting a gas water heater in an apartment or in a private building, since the device must be registered.

The best option is to install all the equipment on the wall according to the design and connect only the water hose to the unit’s connection pipe. You do not have the right to connect a gas water heater with your own hands to a gas hose and perform other work related to a combustible mixture.

Such arbitrariness is subject to a fine, the amount of which significantly exceeds the amount of payment for the work carried out by the specialist.

The procedure for installing the device is not original. In the place on the wall where the device will be located, it is necessary to make markings for fasteners. To do this it is necessary to make calculation of the height of fastenings so that the chimney pipe coming out of the unit vertically has a size of at least 30 cm. And the pipe to the chimney can be laid at a certain angle, the value of which can be determined using the diagram provided below.

This scheme is used to install a Bosch gas water heater, but it is also relevant for water heaters from other manufacturers.

After determining the mounting height, do the following:

Having measured the distances between the fastenings on the column, transfer the obtained values to the wall using a building level and a tape measure;
using a hammer drill, make holes in the wall for dowels or hook brackets;
after screwing in the hooks, hang the unit on them;
Now we install water hoses, screwing them to the inlet pipe of the water heater, as well as to the drain;
to check the tightness of connecting the hoses to the pipes, it is necessary to open the cold water supply and the hot water tap at the point of consumption;
after this, you can attach the chimney pipe to the installed unit using the diagram shown above, intended for a Bosch column; for convenience, it is allowed use of corrugation(for this, a flange corresponding to the diameter of the pipe must be installed in the chimney);
To connect the gas pipe, you must call a specialist who will do it correctly and issue a document confirming the registration of the device.

At this point, the procedure for connecting the gas water heater can be considered complete.

Installation standards

The installation of gas water heaters in buildings with many apartments must take place in accordance with the following documents: SNiP 42-01-2002, SNiP 31-01-2003 and SNiP 41-01-2003.

If the unit installed for the first time, or its location changes, it is necessary to prepare the following documentation:

a certificate confirming the normal condition of the chimney - this document is issued by the services that control ventilation ducts and chimney channels;
technical passport for the water heating unit;
an application from the homeowner to renovate the apartment - it is submitted to the city administration;
a dispenser installation project prepared by a GORGAZ engineer;
application for work to be carried out by gas service employees.

After receiving permission, specialists will carry out insert into the riser(if necessary), connect the hose to the outlet pipe and check the correct installation of the unit itself and the chimney pipe. Next, the gas technician must start the device and set it up.

Additionally, the owner must receive the following documents:

document from technical supervision;
certificate from the fire service;
an act certifying the acceptance of the dispenser into operation.

In addition, this water heater installation project must be entered into the BTI.

In conclusion, we can say that a gas water heater is the most convenient and economical type of device for providing a home with hot water. Its installation and independent connection must be carried out in accordance with established standards, and only up to a certain point, namely, before connecting the device to the gas main.

Installing a geyser with your own hands is theoretically possible. However, it should be taken into account that any work related to gas supply, be it the supply of a pipeline or the installation of fittings, can be carried out by experienced specialists. If you try to perform such actions yourself, the home master faces a fine. But how, in this case, can you install a gas water heater yourself?

There are two types of installation of such equipment:

The column is installed from scratch.
A new column is installed instead of the old one.

When installing a heating unit from scratch, it is necessary to develop a special project that will show the supply of the gas pipe to where the column will be mounted. Such planning of work should be carried out by specialized structures, be it the gas industry or companies that have a license to conduct such activities.

When the project is created and confirmed, and the appropriate permission for installation is issued, then you can install the equipment yourself, without fear of being fined. And it is at this stage that a significant amount of money can be saved.

Important! If the old water heater is being replaced, then no permits or projects are needed to carry out the work. In this case, the work must be carried out in accordance with the existing project.

The official act that regulates the installation of water heating systems is. All requirements for the gas water heater are also indicated here. But given the fact that today, when installing gas supply systems, materials not made of metal are most often used, it is necessary to pay attention to points. This is where all the nuances of working with products made of foam propylene and metal are described.

What to consider when installing a column

Let's consider the basic installation rules that must be observed when carrying out work:

The room must have a minimum area of 7.5 m2.
The minimum pressure readings should be 0.1 atm.
Sufficient ventilation must be ensured.
The equipment should be installed on a wall that has been protected with non-combustible materials.
Placement directly above a gas stove is prohibited. A minimum distance of 10 cm must be maintained between such devices.
A mandatory requirement for installing the device is the presence of a chimney. The diameter of the pipe should be from 120 mm.
The ceilings in the room must be at least 2 meters high.
There must be a gas meter in an apartment with a water heater.

Important! Installation of a gas water heater directly in a bathroom is not prohibited by basic regulatory documents. As a rule, in our time, the installation of these units in apartments is most often carried out in kitchen areas. However, if the speaker was previously installed in the bathroom, then there is no need to reinstall it in the kitchen.

Tools required for installation

To install a gas water heater in an apartment, you need the following tools:

Adjustable wrenches (two wrenches required).
Two open-end wrenches (27 by 30 and 32 by 36).
Sealant. Unipack is perfect.
Tow or FUM tape.

To carry out installation work, you need to prepare the following materials:

Galvanized pipe, 1 meter long. Often such materials are supplied complete with heating equipment.

Advice! If the geyser was not equipped with such a pipe, then you should read the instruction manual, where all the necessary parameters will be indicated by the manufacturer of such equipment.

Gas hose (its dimensions are specified in the documentation that comes with the kit).
A filter designed for rough water purification. Keep in mind that the service life of such equipment directly depends on the quality of the water.
A rosette ring required to lead out the entrance to the chimney.
Dowels that will secure the equipment to the wall.

Installation work step by step

When the chimney and water supply are prepared for the installation of equipment, you can proceed directly to its installation. Replacing a gas water heater is carried out in several stages:

Mark the equipment attachment points. Here you should take into account the minimum length of the chimney, which is 50 cm for rooms with a ceiling height of 2 meters and 25 cm - where the ceiling height is 2.7 meters or higher.

Holes are made in the wall according to the markings.
Hooks are installed to hold the column.
Now the device can be hung on the wall.
We take PVC pipes and connecting rods, through which the pipeline is connected to the inlet and outlet of the column.

The video shows instructions for installing a geyser

Advice! When working with hoses, the use of tow or FUM tape is unacceptable.

Having installed the pipeline, we open the water supply taps (both cold and hot), thus checking the system. Having detected a leak, we simply tighten the rod locking nuts. However, you shouldn’t tighten it too much either - you can damage the seal.

Important! If you identify a leak in connections that were made using tow or FUM tape, be sure to redo them.

At the last stage of installation, gas is supplied to the device. To do this, take a flexible hose: one end is screwed to the gas supply valve, and the other to the gas inlet into the column. Next, you need to crimp the connections and treat them with a soap solution to check for leaks.
We supply gas to the system. If there are no bubbles in the areas with the applied solution, then you can safely put the system into operation.

Advice! When purchasing a gas water heater, check with your consultant to see if the company provides equipment installation services. Large stores have a personal staff of specialists, and therefore can change the gas water heater in the apartment completely free of charge.

Conclusion

A gas water heater is the most obvious means of autonomous heating of an apartment. You can install it yourself, but this issue should be approached with all seriousness, having first obtained all the necessary permits for the work.

Are you planning to install and connect a gas water heater in your own apartment or private house? Then it won’t hurt you to familiarize yourself with all the rules that must be followed during this event, and with the progress of the installation work itself. I am ready to bring all this, including explanatory photographs and diagrams, to your attention.

Bureaucracy

Before performing installation work, you must obtain all the necessary papers and permits, the number of which varies depending on whether you are only replacing the device or installing it from scratch:

Documents required when replacing equipment

If you already had a water heater and you simply want to change it to a newer and more efficient model, then all you need to do is visit the gas service to write the following statements:

For permission to replace equipment at the same location;

On carrying out dismantling and installation work on gas and water mains.

Documents required when installing equipment from scratch

But here a lot of difficulties arise. You will need the following list of documents, without which installation of a geyser is impossible, or rather strictly prohibited by law:

Certified certificate from the ventilation and smoke duct control service, indicating the satisfactory condition of your chimney;
Technical data sheet of the new water heater;

If the equipment has not yet been purchased, but you have already decided on the exact model, then you can simply indicate it in the project at GORGAZ.

Installation project with technical specifications. Ordered from GORGAZ;
Application for reconstruction with the personal signature of the apartment owner. Submitted to the city administration;
Application for installation work. Also submitted to GORGAZ, but only after receiving the project;
Act from the fire service;
Certificate from technical supervision;
Certificate of acceptance of the device into operation.

Also, the placement of the column must be entered in the BTI.

In fact, I don’t recommend taking on the task of installing a gas water heater from scratch at all. Not only will you have to worry about obtaining all the listed documents, but you should also not forget about the need to connect gas pipes to the place where it is located, and this means additional expense and effort. For example, installing the same boiler in a similar situation with your own hands will be much easier and cheaper.

Preparation

Once all the necessary documents are in your hands, you can proceed to the preparatory steps, which should not be neglected even in the case of a simple equipment replacement, and not just installing a column from scratch.

As a rule, geysers are located in the kitchen, and from there they supply hot water to the sink, the bathtub located in the next room and other possible water points. And in order to better navigate the installation of equipment and all auxiliary elements, it is better to sketch out an approximate drawing of the installation location on paper or in a graphic editor in advance:

You will also need a diagram for connecting the water heater to the communications, which may look like this:

Communications

Now we check the state of communications if we are talking about installing a new column instead of the old one, and bring them up if the work is being done from scratch:

Pipe leading to the chimney, must be made of stainless steel or galvanized steel with a thickness of at least one millimeter, as specified in the regulatory document GSN V.2.5-20-2001;
The gas tap is mounted closer to the water heater. Moreover, it must necessarily have a yellow handle in accordance with SNiP 2.04.08-87;

Cold water supply implemented from the riser using a separate pipe equipped with a mechanical filter;
To output hot water, it is best to use a copper tube or corrugated stainless steel with a cross-section of 15 mm;
The installation site, or rather the wall on which the device will be hung, should be covered first with basalt insulating cardboard, and then with a millimeter galvanized sheet. This will completely eliminate the possibility of a fire hazard.

Another nuance that needs to be taken into account before connecting a gas water heater: the volume of the room in which it is located must exceed 8 m3.

Tools and materials

To install a gas water heater, you will need the following materials and tools:

PVC pipe to connect the device to the water supply;

	Apply markings on the wall using a mounting template. As a rule, it can be found in the box along with the gas water heater itself. If none is found, then we mark the locations of the fastening elements using a tape measure.
	Installing a rail for mounting the device, fixing it on the wall using dowels and self-tapping screws, having drilled the required holes in advance.
	We check its horizontal position with a spirit level. Crooked position of the device is not permissible.
	We fix bar to connect. Here again you will need a hammer drill, dowels, screws and a screwdriver.
	Installing gaskets on the bar, ensuring the tightness of each input and output of the column.
	Removing protective plugs from a new column.
	Hanging up the device onto the mounting rail.
	Connect from below connection strip using a suitable key. Then we bring all communications to it.
	Checking the draft in the chimney.
	We connect from above chimney or coaxial chimney. The diameter of the chimney should be 110 mm, length 30-200 cm, and the slope should be at least 2 degrees at the top.
	Connect the drain hose to the safety valve.
	Connecting the device to power supply.
	Checking access to the inside of the gas column.
	Removing the protective film from the surface of the device.
	Open the gas supply valve and perform a test run water heater.
