Connecting a gas water heater on your own is an extremely dangerous activity. In accordance with state regulations, only services with a special license for installation can carry out these works (the same with heating). However, it is allowed to replace the old device with a new one, but not to thoroughly install it from scratch.

Below are the standards for installing a gas water heater according to SNiP, they are valid for apartments and for private houses in Moscow.

1. Room for installing a gas water heater - at least 7m3.
2. The wall on which it is planned to place the equipment must be made of fireproof material (brick, concrete).
3. The presence of good ventilation and windows in the room where the column is installed is a prerequisite.
4. The height of the ceilings is at least 2 meters.
5. To place the device, you will have to find a chimney in the room.
6. Adequate operation of the entire system is possible at a water pressure of 1 atm.
7. Unauthorized installation in the bathroom and toilet is prohibited. In addition, in the kitchen, the unit must be at a distance of at least 10 cm from the hob, but it must not be hung over it.

These were the latest SNiP norms. The old ones are somewhat different. If you have an old type column in the bathroom, you can replace it with a new one - this will not be a violation of the law.

We prepare documents before connecting the gas water heater

Initial installation is often costly and a lot of documentation. However, this fact does not repel the apartment owners.

In the absence of a gas pipeline in the house, you will have to lay the gas supply lines yourself. This will require a lot of funds, so it is advisable to team up with neighbors who also want to install speakers.

What stages of documentation should the owner go through?

First, to obtain consent from gas distributors and transporters for the supply of gas and for the installation of a land plot under the gas pipeline. Plus, calculate consumption and get an extract with technical conditions.

Second, create a project. This includes the conclusion of a contract, the collection of all documents and their thorough examination, obtaining permission from the inspections.

Thirdly, after the completion of the assembly work, an agreement must be concluded with GORGAZ and OBLGAZ.

It is impossible to legalize such activities without the appropriate documents. Below is a list of them.

• a document confirming your ownership of the apartment (photocopy);
• 2nd, 3rd, 5th page of the passport (photocopy);
• a photocopy of the taxpayer identification number (TIN);
• permission to process your personal data;
• a document on the purchase of gas and a letter indicating the conclusion of a contract for the forthcoming work;
• gas equipment maintenance document;
• technical conditions for gas connection and confirmation of compliance with technical conditions;
• a photocopy of the act stating the division of property between the home owner and the gas distributor;
• a photocopy of the technical passport of the gas meter and a conclusion on its verification; a copy of the entire project and a stamp from the Gazprom branch.

How to install a gas water heater

Now we come to the actual installation of a gas water heater in the apartment. After you have managed to register activities in all inspections, lay gas lines, get a full set of documentation and fulfill all technical conditions, setting up a gas column will not be large labor.

Main stages:

1. Remove the front panel and determine the location of the anchors by the markings of the fasteners. Checking the correctness of the markup is carried out using a building level. Drill holes, screw in dowels and anchors.
2. Install the anchor plate (found on most models) and level with a building level.
3. Place the column directly on the plate. A characteristic click will indicate the correctness of this action.
4. Lay a corrugated pipe from the outlet of the water heater to the common chimney. Work the wall with a puncher, insert the chimney there. The space between the wall and the chimney must be sealed with foam.

Choosing a location for installation

The norms for installing a gas water heater in an apartment assume the correct placement of equipment. First of all, they are based on the installation of the hood in accordance with all the rules, the convenience of the location of the water heater and the possibility of communications.

The volume of the room must exceed 8m3.

The wall on which the unit is hung must be fireproof. Otherwise, a galvanized metal sheet with a thickness of up to 1 mm is used. If we talk about at what height to hang the gas water heater, then everything is accurate - from the side panel to the wall at least 15 cm and at least 60 cm of free space in front of the front panel.

In a living space, you can either place a new appliance in the kitchen, or replace an old one in the bathroom. About how to install a gas water heater in a private house, we can say that the installation rules are the same as in an apartment building. These were the requirements for installing a gas water heater in an apartment, private housing. It can also be placed in non-residential specialized premises with appropriate permits.

Training

If you need to replace the column, then first of all we dismantle the old device. Be sure to check the quality of the valve closure on the gas pipe to avoid gas leakage. All valves in the water supply must be closed.

Now disconnect all pipes and a flexible gas hose from the column. The chimney is also dismantled. The column is removed (after detaching the front panel).

Very often the wall needs cosmetic repairs. Old fasteners are removed, and the holes are filled with a special solution.

For a fine installation, the wall is leveled. A special adapter is connected to the chimney for connecting the corrugation. pipes.

Installation

You will need:

• drill (or hammer drill) with a set of drills (0.8-1 cm);
• a set of fasteners (screws, anchors), the type of fastening is selected depending on the speaker manufacturer;
• bubble, laser level.

To gain access to the water heater fasteners, you need to remove the front panel. Further, according to the marking of these fasteners, mark on the wall the places where the anchors or hooks are attached. The location of the marks must be checked by level. Using a drill, holes are drilled (2.4 pcs.), Where anchors or dowels are then placed.

Most modern models have a plate that is primarily attached to the wall. This greatly simplifies the installation of the gas column. The plate is applied to the wall, leveled and the fixing points are marked.

Drill a hole at the desired height and fix the plate, mark it with a level. Next, drill the remaining holes. This completes the installation.

It remains to fix the water heater. Set the bezel aside to avoid damage (it is too early to attach).

The chimney for the column is most often a corrugated flexible steel pipe. Walk along the wall with a puncher, then insert the chimney. The remaining gap is either sealed with a non-combustible insulation, or simply filled with foam.

Gas connection

When installing the equipment for the first time, it is required to lay a pipe with gas. This work is carried out exclusively by specialists of gas services who have the appropriate permits. To do this, you will have to fill out an application and invite masters. They will be engaged in tapping a tee into the pipe going to the plate. A pipe is connected to the tee and then moves to the installation site.

If you know the exact model of the device, bring the tube to the place of its joint to avoid the use of a flexible hose. Note that there is a gas valve in front of the connection. First of all, the column is installed on the wall, and therefore the gas pipe is supplied to it.

An even easier way is to bring the edge of the pipe up to 50 cm to the installation site and complete the path by connecting a gas valve. In this case, you do not have to rely on the work schedule of the gas service masters, and carry out the installation at a convenient time.

Water connection

A pipe with cold water is directed to the device, and hot wiring is carried out throughout the house. It is better to connect to the water heater using an American (connection with a movable nut).

Be sure to place ball valves as shut-off valves in hot and cold water lines.

The durability of the heat exchanger depends on the purity of the water. Therefore, it is advisable to install a filter.

There are two ways to route pipes:

1. At a distance of less than 30 cm, connect using a flexible hose or copper tubing.
2. Depending on the material of the main wiring, make a direct connection of metal-plastic, polypropylene, steel, pipes.

Starting and configuring the gas column

Check for seams before starting. Gas and water pipes must be tight. To check if this is the case, there is a tried and tested way:

 treat all connections and fittings with soapy water;

• open the gas cock;
• check for bubbles on the connections;
• Plumbing joints are much easier to check, just make sure they are dry.

The launch is carried out according to the instructions of the purchased device. Another important step is customization. It is produced using a pressure gauge (the price of this device can vary greatly depending on the functionality). The gas pressure is affixed with the adjustment bolt, and the air supply - with the shaber.
