For heating equipment, which is installed in private houses, almost all known types of fuel are used - firewood, peat, coal, electricity, natural gas. In our country, with its resources, the gas type of equipment has become one of the most popular. It is distinguished by a rather low price, relative availability. The designs of boilers that are used for heating houses are notable for their ease of use and safety in operation, but, of course, subject to a number of rules.
The principle of operation of the boiler
Gas-fired heaters can differ from each other in design, technical characteristics, they all use one principle - heating the working environment of the heating system with the help of burning fuel, in our case natural gas.
Gas is used not only for space heating, but also for heating water. To do this, either water columns or double-circuit boilers are used. The equipment that is used today is equipped with highly efficient safety systems - they keep the gas burning process under control. But, nevertheless, there are binding rules for using gas equipment and their observance can become a guarantee of safety.
Before putting the equipment into operation, the user must make sure:
- In the presence of the required amount of working fluid in the heating system.
- That the burner, safety valve, are in good condition.
- Measuring instruments show correct data.
- The operating temperature of the boiler must not fall below 65 degrees. This may cause condensation.
Rules for placing the boiler
The area of the room in which the gas heater will be installed must be at least 7.5 square meters. m The minimum distance between the floor and the ceiling should not be less than 2.2 m. A window should be installed in the room through which street air enters.
The door to the room should open towards the street. It is unacceptable to use switches in the boiler room, they must be installed outside it.
The room in which the gas boiler equipment will be operated must be equipped with supply and exhaust ventilation. Its performance should be 15 cubic meters. m of air per cubic meter. m consumed gas.
When installing the boiler device, it is necessary to maintain a certain distance between it and other objects. So, before items made of combustible materials should be 250 mm or more. The distance to the elements that are made of fireproof materials should be 50mm.
From the chimney pipes these distances should be 400 and 150 mm, respectively. Before installing the gas boiler, it is necessary to put the room in order, in particular, the floor should be flat without any biases.
From the chimney to combustible parts - 40 cm, to fireproof - 15 cm. The device is mounted on a perfectly flat plane, without slopes.

Ignition instruction
One of the nodes of the design of gas boilers, which they differ from each other - ignition system. Therefore, when starting up boilers of various types, certain subtleties may exist. Before starting the device in operation, it is necessary to study the operating instructions. How the ignition sequence looks like this:
1. Visual inspection of the system for leaks. For this, the thermostat is set to maximum. In this case, automatic switching occurs.
2. When performing this operation, the boiler must be connected to the mains. After it starts to work, a little noise will be heard, and after filling the coolant system, the system will automatically ignite and the boiler will return to the set operating modes.
How to turn off the boiler
If during a certain time, the use of the boiler is not planned, then it makes sense to turn it off. First of all, close the gas supply valve. Installed control automation and pumps must be de-energized. Of course, we must not forget about the shutdown of the coolant and water supply, if it is used for its heating. If it is expected that during downtime, a temperature drop below zero is possible, then you will have to drain the water.
REFERENCE! To turn off the boiler, you can invite the masters from the service organization.
Self diagnosis
The operation of gas equipment will be greatly simplified if it provides for an independent diagnosis system. Most manufacturers have been installing similar systems on their products for quite some time. Error messages are displayed on the built-in monitor. Some manufacturers, error A7, indicates a malfunction of the temperature sensor. Self-diagnosis of gas equipment simplifies its operation. The decoding of the codes that are displayed on the monitor is usually given in the instruction manual.
Frost protection
One of the key rules for the safe operation of gas equipment is the guarantee of a minimum temperature of the working medium, which will not allow it to freeze. If the water poured into the heating system freezes, then this will lead to irreparable consequences, in particular, rupture of the radiator.
In most models in use today, continuous monitoring of the state of the coolant. They provide frost protection, one of the components is a circulation pump, which is turned on to ensure the forced movement of water (coolant) through the system. As a rule, it turns on automatically when the water reaches a temperature of 10 degrees. If, for certain reasons, the temperature drops even lower, then in addition to the pump, an auxiliary heater is turned on, heating the water to a predetermined level, for example, 18 degrees.
REFERENCE! In order to avoid freezing of pipes, a mixture of water and glycol is poured into the heating system, of course, the possibility of using such a solution can be indicated in the instruction manual.
What to do if a malfunction occurs
Even during proper operation of the boiler equipment, certain problems may occur. In some boilers, the following interruptions may occur:
- boiler overheating;
- temperature sensor failed;
- during operation, the boiler runs too noisy.
As a rule, some breakdowns can be caused by violations of operating conditions, factory defects, pressure drop in the gas pipeline, voltage drop in the supply network, errors made during installation of the gas boiler.
Some owners of gas devices are trying to solve the problems on their own, but it is more advisable to call specialists from the service organization.
IMPORTANT! If there is a smell of gas, it is necessary to stop the boiler and call specialists.
General safety rules
Manufacturers of gas heating equipment pay much attention to its safety, despite this, equipment of this class can serve as a source of danger. The fire department of the Ministry of Emergencies does not tire of constantly talking about precautions, in particular, it is unacceptable to purchase gas boiler equipment from companies that do not have the appropriate license. The delivery should include a manual or instruction manual.
Installation of equipment and its commissioning can only be done by employees of the respective organizations. Such equipment must pass a technical condition check. As a rule, this is done once a year.
In the boiler room, it is unacceptable to store items that are not related to the operation or maintenance of the installed equipment. And yet, the upper limit of the heating of the coolant should not exceed 90 degrees.
