Do-it-yourself installation of a gas column in an apartment - norms, rules and step-by-step instructions

Installation of equipment

The sequence of actions when installing a column usually looks like this:

Marking is applied to the wall: holes will be made along it. The column should be located at a sufficient distance from the stove and at such a height that the viewing window is just at the level of the user's eyes. The length of the vertical section of the chimney extending from the column should be 500 mm or more when ceiling height from 2 meters, and not less than 250 mm - if the distance from the ceiling to the floor is equal to or exceeds 2.7 meters. You should also take into account the requirements of the norms mentioned above.
Having drilled holes, dowel sleeves are laid in them, and then mounting hooks are screwed onto which the column is hung.
A tee with a ball valve and a filter cuts into the cold water pipeline, which is connected by a pipe or hose to the inlet fitting of the water circuit of the column. With a collector scheme, the pipe is laid from the collector branch pipe, a ball valve and a filter are installed on it

Please note that the inlet and outlet fittings are not equivalent - it is important to identify the inlet. If a steel pipe is used for connection, threaded connections must be sealed with tow, flax, FUM tape or thread "Tangit Unilok". In the case of using a hose (flexible connection), there is no need to use a sealant - the tip of this element is already equipped with a gasket.
Similarly, a pipe for distributing hot water is connected to the outlet fitting.
Next, slowly open the root valve on the cold water pipeline

In this case, you need to watch for leaks at the joints. If it appears, you need to tighten the nuts (for flexible piping) or add a sealant.
The gas fitting of the column and the tap on the gas supply line are connected by a hose, which must be crimped with clamps. The tightness of the connections is checked using soap suds - if there are leaks, it starts to bubble.

It remains to fix the pipe on the chimney pipe and mount the draft sensor according to the instructions. The second end of the pipe is inserted into the chimney channel by means of a special adapter. Now you can test run.

2 What are the requirements for installing gas water heaters in a private house

A prerequisite for any potential user of a water heater is to know what are the requirements for a gas colony in a private house.

First of all, you need to know the snip gas water heaters for a private house, which sets the requirements for the room in which the water heater is planned to be installed: the minimum area is 15 square meters, the ceiling height is at least 2 meters, the presence of a window is at least 0.5 m 2, the presence of ventilation (or installed hood for gas columns in a private house), water pressure - from 0.1 atm., the wall under the gas water heater must be made of brick or concrete, otherwise insulation with a special basalt cardboard is necessary.

In addition, the standards for installing a geyser in a private house are required to comply with the following parameters:

1. There should be a margin of 60 cm in front of the front panel of the gas column;
2. The distance from the water heater to the gas stove is at least 20 cm;
3. The stopcock is mounted before the column is installed.

The rules for installing a geyser in a private house also regulate the procedure for legalizing the installation of a geyser.To obtain permission to install a water heater, you must obtain a project for your house and check the condition of the chimney (after which you receive an act), then the owner of a private house draws up an application for the conversion of his home.

You will also need those column passport, or its model (if the latter has not yet been purchased). After that, you can contact GORGAZ to carry out the tie-in.

You should know the subtleties at each stage of installing a geyser in a private house. This will be needed both for partial installation with your own hands, and for calculating all the nuances of the work. Experienced professionals share the following tips:

• If you decide to disguise the geyser in a snag cabinet, this is possible. But you should be aware that such a cabinet should not have a bottom, and the side walls should have high-quality insulation;
• If you hesitate in choosing between installing a chimney pipe, opt for corrugations made of laminated aluminum. Such a pipe is perfect for a private house, as it is easy to install, quite reliable and inexpensive, and inside it has steel pipes that prevent sagging;
• If you plan to mount a geyser instead of an old one that has become unusable, then it is best not to change the installation site. So you save time and some money;
• Remember that in case of unauthorized insertion into the gas pipeline and connection of the gas column, you will face administrative responsibility, in the form of a fine.

Paying attention to customer reviews, there is often a problem when the geyser freezes in a private house

Masters advise first of all to pay attention to the draft in the chimney

Most often, the problem is reverse thrust and causes failure of the water heater. The collection of gas column condensate in a private house may appear if an ash pan is not installed in the system, and condensate is already drained from it. Otherwise, this problem will occur every winter season.

The presence of such an installation in a residential area is a reliable, popular, economical option for obtaining hot water of the required volume with a centralized gas supply or from a cylinder.

In addition to the specific information on the site, you can also study specific problems for other people on this topic who have already bought a gas water heater or instantaneous water heater and thus avoid them. You will find a regularly updated list of such problems and their solutions.

This is the least expensive and time consuming option. When replacing, there is no need to obtain a project. Before starting work on replacing an old water heater, it is necessary to obtain certified copies of the schemes, a plan for installing gas, water, and smoke systems from the Housing Office. The gas supply plan must indicate the location, technical parameters of the device.

After receiving the documents, you must write an application to Gorgaz with a request for permission to replace the old equipment with a new one, while maintaining its previous location, an application for permission to work on gas and water communications in your home.

Norms and installation requirements

Installation work is carried out in houses or apartments with a gas energy carrier. AT SNiP 42-01-2002 and joint venture 42-101-203 the rules are clearly spelled out for domestic gas installation speakers in a private house or apartment:

• a room with an area of ​​at least 15 m2;
• ceilings from 2 m high;
• distance from the column to the floor covering - 1 m;
• a window with dimensions of 0.5 m2, which opens freely;
• distance from the column to the valve - 2.2 m;
• door width in the kitchen - 80 cm;
• the dwelling is equipped with an exhaust hood or ventilation system;
• pipeline with pressure from 0.1 atm;
• the column body is 20 cm away from the stove, while the front panel does not reach the furniture by 60 cm;

• free space near the water heater - 5 cm on the side and 15 cm on the bottom.

Important! Before installing the equipment, it is necessary to install a shut-off valve on the gas pipeline

Where can I install

Connecting a household gas flow column is possible when it is transferred from one room to another, replaced, or initially installed. The device must be located in the kitchen with a chimney 12 cm in diameter or ventilation ducts.

Important! Modern gas water heaters cannot be installed in the kitchen due to high humidity and lack of a chimney. In private houses it is allowed to use instantaneous water heaters if there is a coaxial pipe brought out into the street

Through it, air enters the closed compartments and combustion products are removed. Property owners are advised to:

In private houses, it is allowed to use instantaneous water heaters if there is a coaxial pipe brought out into the street. Through it, air enters the closed compartments and combustion products are removed. Property owners are advised to:

1. Apply to ZhEK to obtain a diagram of gas, water mains and a chimney system;
2. In the fire inspection, receive an act of checking the technical condition of the chimney;
3. Visit the gas service with an application, building layout from BTI, documents of the owner and passport;
4. Wait until the request is considered and granted.

Advice! If you live in a private house and install a heater on the basement floor, install protection valves and a gas analyzer.

In apartments equipped with an electric stove, it is forbidden to connect a column. A similar ban is imposed on buildings over 11 floors in height or when redevelopment. Studio apartments are also included in the list of residential properties where an instantaneous water heater cannot be connected.

Important! When replacing an obsolete column with a new one, in contrast to the transfer, if you have a project, you do not need permissions.

Who is eligible to install

Only laying a line in apartments without gas supply is allowed on their own. The owner needs to obtain documents authorizing the supply of gas fuel, as well as conclude an agreement with the authorities that will carry out the installation work. Among the documents you will need a contract for the purchase of gas, maintenance of equipment, copies of its schemes and a gasification project.

Only laying a line in apartments without gas supply is allowed on your own

It will not work to install a gas household column on your own. It is carried out only by state services and specialists who have a license and permits. Unauthorized tie-in into the gas pipeline line is considered as fuel theft. The violator is subject to a fine of 45 thousand rubles for connecting the heater, an administrative fee of 2 thousand rubles. In part 3 of Art. 158 UK The Russian Federation provides for imprisonment for a period of 2 years.

If you have been able to obtain a permit for independent work, it is recommended that you act consistently and follow the safety rules.

Rules for installing a geyser

As you probably understand, in order to install any gas appliance, you must comply with the relevant rules and regulations. If you neglect at least one of them, you risk not only getting into trouble with the law, but also causing the death of people close to you.

If you already have an old speaker, then you can easily replace it with a new device yourself. However, do-it-yourself installation of the device from “a” to “z” is prohibited.

Before proceeding with the connection of the geyser, you should carefully read the rules for its installation.

If you decide to connect a gas water heater yourself, or entrust only part of the work to special services, then you need to familiarize yourself with the basic rules of SNiP for such installation. They are applicable both in the apartment and in a private house.

SNiP standards:

• Installation of a gas type column is possible only in a room with a volume of at least 7 cubic meters. meters;
• The wall you plan to hang your speaker on should be made of a non-combustible material such as brick or concrete.
• In the room where the gas water heater will be installed, there must be a window and a good ventilation system;
• In an apartment with a column, the ceilings must have a height of at least 2 meters;
• In order to install a column, you need to find a chimney in the room;
• For normal operation of the column, the water pressure in the system must be at least 1 atm.
• You can not install a column in the bathroom and toilet, and the gas unit must be at least 10 cm from the stove. At the same time, a column cannot be hung above the stove.

These are the new norms of SNiP regarding the installation of a geyser. The old norms were somewhat different, so if your old column is installed in the bathroom, you can put a new unit in its place, and this will not be a violation of the law.

Tools and materials

During installation, you will need the following:

1. Impact drill or hammer drill for concrete work.
2. Open-end wrenches, sizes 27/30 and 32/36.
3. Key gas (pipe).
4. Sealant "Unipack".
5. Sealant for pipe connections - tow, sanitary flax or FUM tape.

In addition to the water heater, you will need to purchase:

A socket is a decorative detail through which a galvanized pipe is inserted into a wall chimney.
An oblique filter (mud collector) for water purification from large mechanical impurities.
Optional: a water softening system that prevents scale build-up of the column heat exchanger. In this capacity, you can use a cartridge with an ion exchange resin or a hydromagnetic system.
Piping parts (elbows and tees), fittings, hoses and cut-offs taps - for connection columns for plumbing

Please note: hoses (flexible pipes) are easier to connect, since the connection does not need to be additionally sealed (gaskets are built into the threaded lugs).
Gas hose, through which the column is connected to the gas distribution network. It must be of sufficient length and the connecting thread corresponding to the thread on the column gas pipe

If the hose tip does not fit the column nozzle, an additional adapter must be purchased.
A pipe made of galvanized steel with a wall thickness of 1 mm is used to connect the appliance to the chimney. The requirements for wall thickness are due to the high temperature of the exhaust gases - a thin-walled part will quickly burn out. Many models have such a pipe included.

If you had to buy it yourself, pay attention to the dimensions of the section: their values, as well as the required dimensions of the chimney, must be indicated in the column passport; if there are no special instructions - navigate on the dimensions of the flue pipe. The minimum allowable length of this pipe depends on the height of the ceiling:

The minimum allowable length of this pipe depends on the height of the ceiling:

• 2.0 to 2.7 m: 50 cm;
• over 2.7 m: 25 cm.

The hose should be chosen as carefully as the water heater itself. A poor-quality product can cause a gas leak, the consequences of which everyone is well aware of. Gas hoses from a reliable manufacturer come to retail with a certificate - do not be too lazy to ask to see it.

How to install a geyser

Self-installation is prohibited by the law of the Russian Federation, but since representatives of the gas service often remain elusive, we recommend that you mount the device yourself. Specialists should only be invited to connect the hose to the gas pipe and check all connections for leaks.

What to bring with you

First of all, prepare all the necessary materials and tools. You will need:

• new geyser;
• PVC pipes for water supply and metal-plastic pipes for gas;
• fitting;
• taps - gas and water (it is better to use ball valves);
• salt and magnetic filters;
• corrugation or galvanized pipe (if it comes with a column);
• Mayevsky's crane;
• a ring to make an entrance to the chimney;
• gas hose (its length depends on the distance between the pipe and the column);
• water hoses (also select the length depending on the distance);
• dowels and screws;
• gas key;
• pipe cutter;
• set of wrenches;
• drill;
• level;
• sealant, FUM tape and tow;
• soldering station for pipes.

In the case of a private house, you may also need a metal (asbestos) pipe to remove smoke. Its diameter should not be less than 120 mm, and its height should be two meters or more.

We remove the old

This is an old geyser, the use of which is not safe. It is best to replace it with a modern analogue.

If you already had a water heater, then, first of all, you need to dismantle it. For this:

1. Close all gas valves.
2. Using a spanner, unscrew the fixing nut on the hose.
3. Then remove the hose from the column. In the event that the hose is new and has no damage, then it can be used further. Otherwise, buy a new one.
4. Now you can proceed to disconnect the device from the water supply. Turn off the water (if there is a faucet near the column, then it is enough to turn it off, otherwise you will have to block access to the water for the entire apartment).
5. Remove the connecting pipe located at the outlet of the column and pull it out of the chimney.
6. Dismantle the water heater by removing it from the mountings.

Direct installation

Installation of a gas water heater takes place in several stages. After choosing a place, you need to prepare all communications: plumbing, chimney and gas pipeline.All this should be in close proximity to the future column, so that after installing the latter, you only have to connect the hoses to the pipes.

To connect the gas to the geyser, be sure to call the specialists of the special service.

1. So, the first step is to mark the place for the water heater. I hang it on a special bar that comes with the device. This is where you will need a drill, dowels and self-tapping screws. It is better to mark up with a level.
2. We drill holes, drive in dowels, apply a bar and fasten it to the wall with self-tapping screws.
3. The next step is to connect the water heater to the chimney. This is done using a corrugation or a metal pipe. Installing the latter is easy. The pipe must be put on the pipe (and the sleeve must also be tightened with a clamp) of the column. The other end is inserted into the chimney and covered with cement (possibly with asbestos). But do not forget that the horizontal section of the pipe cannot exceed 6 m and you cannot make more than 3 corrugation bends.
4. Now you can proceed to connect the column to the water supply. As mentioned earlier, the installation of pipes and branching is best done in advance. In this case, it is not always a good option to tie into the nearest line (if the pressure in it is weak, cut directly into the main pipe going to the apartment). Be sure to install a tap on the new branch that goes to the water heater so that you can repair the column or replace it without turning off the water in the entire apartment or house. To carry out the pipeline, you will need metal-plastic pipes and a soldering iron, as well as a faucet, couplings.
5. After finishing work with the hot and cold line piping, you just have to connect the hoses to the appropriate outlet and inlet to the column and to the pipes.

It looks like a chimney made of corrugations. The ring has a purely aesthetic value.

This completes your work. Connection to the gas pipe is carried out by specialists of the relevant service. A ball valve is also placed at the column inlet, all connections are sealed and then checked for leaks.

Unit selection guidelines

1. Which appliance suits you best: electric or gas.

2. Having calculated how much hot water you need, select the volume storage water heater or instantaneous power.

3. Decide on the place of installation of the device for water heating: on the wall, above the sink or under it and choose the model you need.

To figure out which is better - a boiler or a gas water heater, consider the pros and cons of both devices.

Advantages of the boiler:

• Ease of installation. For the installation of a storage water heater, it is not required to collect any documents and permits. No need for good ventilation and chimney.
• The ability to provide warm water to several points of water intake at once.
• Independence from the pressure in the water supply. Where the geyser does not turn on due to low pressure, the boiler will work properly.
• Noiselessness. For heating, a tubular electric heater is used, which does not make any sounds.

Disadvantages of storage water heaters:

• Long reheat time compared to columns. If the hot water in the tank runs out, you will have to wait from 30 minutes for the next portion to heat up (the reasons why hot water does not flow are described).
• Limited amount of water.If you choose the wrong volume, then there may not be enough water to meet the FGP needs of all residents.
• Dependence on electricity. If you turn off the light in the room, then the water will gradually cool down.
• Large dimensions. This can be a problem in small apartments with small bathrooms, where every square meter counts.

Scale accumulation. From time to time, the boiler requires cleaning from salt deposits. If you do not regularly perform preventive maintenance, then over time the water heats up more and more time.

In turn, geysers have the following advantages:

• Instant heating. When you open the tap in just a few seconds, the consumer receives hot water.
• Unlimited water. If there is water in the apartment, then the column can work constantly. The amount of water is not limited by the size of the tank.
• Small dimensions. New models are compact and do not take up much space in the kitchen.
• Independence from electricity. If the house turns off the light, the column will continue to work.

Disadvantages of gas water heaters:

• The need to collect additional documents during installation. Before you install a geyser, you must coordinate the project with utilities and obtain permission.
• The need for a quality chimney. For the operation of a gas water heater, it is necessary that the products of combustion go outside. This requires a chimney, the state of which will have to be monitored all the time.

  If it clogs, then at best the protection will work and the flame will go out. If for some reason it does not work, there is a danger of carbon monoxide poisoning.

• Pressure dependency.If there is a weak pressure in the water supply system, the gas will not open and the column will not work. Modern models with the ability to adjust the pressure inside the device partially solve this problem.

  Also, if two points of water intake are connected and water is turned on in the second one, the temperature in the first one will drop. This is not very convenient when the temperature of the water changes during the shower.

Impossibility of placement in the bathroom. Due to safety standards, gas flow heaters are not allowed to be installed in bathrooms.

To decide what to choose, it is important to consider the installation location. If you live in a private house that is heated by a boiler, it is advisable to purchase an indirect heating boiler, which will be the most profitable. Part of the heat that goes to heating will go to heating tap water

It is advisable to purchase a combined model that has an additional heating element in order to provide hot water in the summer

Part of the heat that goes to heating will go to heating tap water. It is advisable to purchase a combined model that has an additional heating element in order to provide hot water in the summer.

In an apartment where there is no gas meter and 1-2 people are registered, you need to install a gas water heater, which will be cheaper than a boiler due to a fixed payment for gas. An additional argument will be the small size of the apartment; a compact gas flow heater is better suited for Khrushchev.

If you have a nightly rate for electricity, get a boiler with a large tank capacity, because it will be most economical to turn it on at night and then use heated water during the day. Thermal insulation is installed between the body and the tank, due to which the cooling occurs very slowly.
