Gas speakers are called water heaters, which operate based on gas combustion.
These water heating devices are very beneficial to the fact that in the minimum amount of time you can get the desired amount of boiling water without the slightest effort. The first columns began to appear during large housing construction in apartments and houses in which there is no central heating or there are problems with the supply of warm water in the cottages. This is an excellent choice for people who would like to save electricity, especially in those villages where the problem with constant flow of current is very frequent.

Principle of operation of gas speakers
The principle of operation of these devices is simple: Ice water from the pipe falls directly to the heat exchanger, under which the burning gas burner is located. The combustion gases are derived through a specially built-in pipe - chimney, and oxygen comes in a natural way through ventilation systems. The use of various water heaters assumes that a certain amount of time should be used to obtain the desired temperature, and the stronger in power will be the gas column itself, the faster and more liters per minute it can produce hot water. Standardly choose heaters with a yield of 16-17 liters per minute, as it is supposed to use immediately on several waterproof points in the house, such as bathroom and kitchen.
Gas chimney installation scheme.
Three types of gas columns are isolated: manual, piezorozhig and electronic.
The first and simple type is manual, drives with matches and is practically not used now, as it is unsafe.
Piezorozhig: Work begins with an external influence on the button, as a result of which the spark appears, the burner lights up from it, and the water heater is activated.
And the most common now - electronic.
Tools for setting columns
In all the instructions for gas water heaters, reminders are constantly written that they must be set by experts who have admission to work and special qualifications to avoid unwanted accidents, as, by installing in the apartment, you are dangering not only yourself, but also Your neighbors. And if state bodies learned about the lack of permission to work this type, you can get a fine.

The correct functioning of such structures depends on the correct installation. If you still decide to engage in self, then you need to carefully prepare. Release the workplace from unnecessary items that can slow down the process and prepare all the tools that can be useful. Namely:
The chimney scheme for the gas column.
- Gas column design;
- Pipe for water supply from PVV;
- American fittings;
- Tube for supplying gas from metal plastic;
- gas crane;
- Magnetic filter;
- saline filter;
- Fittings for metal plastic;
- Water control faucet;
- corrugation;
- a set of dowels and screws;
- Maevsky's crane;
- electric drill;
- Truboresis;
- Soldering lamp for pipes;
- Set of combined keys.
Choosing a suitable location and conditions for installing the device
In the room where the installation of the gas column will be held, the standards must be observed, first of all, for the safety of the tenants themselves:- The volume of the room should be at least 7.4 m³;
- Be sure to be direct air access - ventilation;
- The height of the room is at least 2 meters;
- Chimney must be installed;
- It is strictly forbidden to install gas columns in the bathroom;
- Material on the wall where the water heater will be attached, should be from non-flammable material;
- The column cannot be placed near gas plates and open fire.
If all this is complied with, you can set smokers.
Selection of exhaust pipes for water heater and chimney installation
Diagram of the chimney device for the gas column.
The chimney for the gas column is called a tube that displays the burning gas from the heating system.
The correct exhaust pipe of combustion products is the highest moment in installing the water heater. And not just like that. Only with a high-quality installation can not worry about security.
There are several types of pipes for chimney of the gas column:
- Corrugated, they are beneficial to the fact that they are available at a price, they can be stretched to about 2.5-3 meters in length or even longer by increasing another pipe with a metal-based tape.
- Aluminum hoods, they are convenient in that it is absolutely immune to the harmful external influences of condensate formation, very easy and available in the installation. The only drawback of such a pipe is in the cold season will have to be additionally insulated to avoid glaciation.
- Coaxial exhaust pipe is now used much more often than the rest, since with the help of such a chimney air for ventilation goes through the same pipe from the street, and not out of the room, because it has another tube to exit combustion products.

Setting the chimney for column
When installing smoking pipes, certain norms must be observed:
Scheme of the gas column.
- It is forbidden to include gas water heaters without chimney recorded in it;
- The exhaust process inside the chimney should be uniform and constant;
- The tube material must be non-flammable, resistant to the release of condensate (or during operation, rotting the pipe walls, burning products will fall into the residential premises), to corrosion and mechanical effects on it;
- There is a chimney outside only in a vertical position;
- The number of bends of the tube should not be more than three;
- The chimney must be as sealed as much as possible to exclude gas entering the room;
- The chimney must necessarily comply with the standards installation standards;
- It is forbidden to remove the chimney pipe into the indoor indoor or in the interval between the floors;
- The pipe should be open access to quickly troubleshooting if necessary;
- You can not use ventilation systems for the output of combustion products;
- The chimney tube must be no less than 0.4-0.5 meters above the roof.
The easiest way is to install a corrugated pipe for chimney. Plus, it is that it is flexible and can be stretched, for example, if when the water heater is replaced, there is not enough length to the opening of the output of combustion products. The width of the chimney tube must correspond to the size of the gas pipe in the water heater. Sumy corrugation is inserted into the opening of the gas outlet, and the other it is placed in the chimney. Chimneys of our time are made in the form of sandwiches.
Installation of metal chimney with their own hands
- First of all, the distance required for the chimney is accurately measured, and special tubes, fastening clamps, nodes to build pipes between overlaps, adapter from a column and an umbrella to cover the place to exit combustion products;
- The installation of the chimney begins from the bottom - from connecting to the gas column. For this, special adapters are taken, and the joints themselves are impregnated with sealant;
- The pipe is joined into which the valve for increasing traction is installed;
- Next, the remaining parts of the chimney are installed, fixed by the clamps every 1.6 meters;
- Where the chimney pipes pass through the layers of overlaps, the protective nodes set to exclude the occurrence of fires. The yield of chimneys from the roof is carefully isolated with a plug.
Installation of the gas column
To begin with, hooks are fixed on the wall to which the water heater will hang. If there is a tile on the wall, then it will be drilled by a special pen on the conventional drill, it is not necessary to include shock mode, so more likely that the tile is not deformed. Read all that may be needed for installation, it is important not to forget to purchase hoses for hot and cold water with threads of the desired size and length. Before connecting the gas sleeve to the gas supply tube, you need to check the edge of the smooth tube, as the Paronite gasket will be used.
If the edges are rough, then they are aligned either with a file or shallow emery paper. It is much more convenient to connect the column to the hoses in the removed state. In order to seal the gas pipe thread connections, you can use tangite tape. Screw threads laid by the thread of strengthening cannot be promoted, as the tanta ribbon will lose its properties. Be sure to check the quality of all connections than something well foams, for example, liquid soap. If there are fistula, they must be eliminated - everything is united. Remove the lid from the column and connect the hoses for water. Water connections are best strengthened by flax with a special plumbing impregnation. After the assembly, water is necessarily turned on, an inspection is carried out for the presence of leaks. If somewhere slightly dripping, there is nothing dangerous in this.
Gas reins need to be coated with special compositions with zinc particles. Fix the chimney on the column. Next, they fix the column on the wall and adjust, opening the gas valve to the maximum so that the gas supply began. Hot water opens and the work of the water heater begins.
