How to turn on a gas boiler
To ensure a comfortable stay in any house or apartment you need to have good and high-quality heating. Where it is not possible or necessary to connect to the central heat supply system to the home, autonomous heat supply complexes are used. One of these is a gas autonomous heating installation.
How to light a gas boiler? The gas heating system is installed mainly in houses; in apartments, a wall-mounted compact boiler is used. Installation and adjustment must be carried out only by qualified specialists, since incorrectly connected gas equipment can lead to dire consequences. Natural gas is highly flammable and highly flammable. Gas-powered installations must be constructed with the required quality and reliability.

First start of a gas boiler
After the installation work on the assembly and installation of the gas heating system, commissioning activities are carried out. They include a test run of the device as a whole. The goal is to customize the equipment and all its elements.
How to fill the system with water, removing plugs
The first start-up of a gas boiler and warming up of the internal heating system is necessary after installing a new heating system, and it is also performed when it is prepared annually after a summer in storage. Before switching on, an external inspection of all equipment is always carried out.
It usually includes:
- Internal wiring pipes;
- Heating radiators;
- Circulation and booster pumps;
- Filter kit;
- Expansion tank;
- Automatic shut-off valves;
- Security block;
- Autonomous power source in case of power failure.
If a positive inspection does not reveal any comments: the presence of external damage, the formation of leaks in gaskets and pipe joints, or the absence of any elements, then we can begin filling the system with coolant. After filling, do not forget to carefully check the serviceability of the elements and piping. Finding and eliminating leaks found in time is very important.
If you don’t pay attention to the task, and at the height of the heating season, when the temperature outside the door is below zero, you will suddenly have to urgently resolve an emergency situation with a complete or partial shutdown of the heating of the house. And this may not happen during the day, but at night, when everyone is sleeping. In addition, incoming water from a breakthrough can cause significant harm and damage to property.
To fill the heating complex with coolant, open the centralized water supply tap. The location of the shut-off device may differ in different installation models, but, as a rule, this is a tap located under the boiler. According to the operating instructions for starting the equipment, the valve opens, but not all the way, this reduces the accumulation of air in the system.
We produce and monitor the injection of the required pressure value using a pressure gauge. This device is specially installed in the boiler to monitor the pressure status. If the own pressure from the centralized water supply is not enough to reach the required filling, we turn on the booster pump, which serves to create working pressure.
After receiving approximately one and a half or two atmospheres, turn off the pump. If the system does not have a pump or it is not provided, then we connect a pressure pump. Its task is to ensure the injection of coolant during the first starts, creating the required pressure in the pipes.
Important! The control features of such a pump are indicated on the panel and in the operating instructions. But most often specialists with their own equipment are invited to these events.
When supplying water, you must simultaneously monitor the pressure gauge. If the pressure stops or decreases during filling, there is a fault in the line.
Bleeding the air
How to light a gas boiler? Bleeding air pockets and residual air from the system is carried out by opening special drain valves. They are installed on radiators and upper points of the heating complex; they mainly operate in automatic mode.
These are special vents that, when air forms in the pipes, accumulate in them, and then are automatically released until water appears.
They are installed at the highest points of the distribution, since air is lighter than water and accumulates at the top. To do this, you will need a rag, a bucket, a set of screwdrivers and keys. The procedure takes about 5 minutes.You can determine that the air has escaped by the disappearance of escaping air and the appearance of constantly incoming water if the discharge is performed mechanically. Only after this can the taps be closed.
Crimping the circuit
Pressure testing is a very necessary event. Often, after filling the operating pressure, you may not be able to identify the weak point. It is with the help of pressure testing that it is checked and identified. The idea is to increase the pressure twice as much as the working pressure.
This is done with water or compressed air. Problems that have not yet appeared immediately make themselves felt. In any case, it’s good when everything can be eliminated and replaced before the cold weather begins.
Pressure testing of the system is often not performed due to the desire to save money. But be careful, this event is a measure to ensure trouble-free operation. When testing and checking the device after the summer period, it is very important to ensure its functionality.
Flushing the device
How to light a boiler? After carrying out the above work, washing is carried out. It is a mandatory and necessary event. After filling with coolant and pressure testing, a lot of debris and metal shavings accumulate in the system. This debris must be flushed out of pipes and equipment.
To do this, water is supplied under pressure of four atmospheres, several times in a row. The supply ends only after clean waste water appears. At the end, all filters are opened and all excess is removed from the filter elements and meshes.
Features of turning on a gas boiler
How to turn on a gas boiler? When starting, follow the rules specified in the passport and take into account the operating features listed below.
How to start a gas boiler? We list the main most important features:
- Particular attention should be paid to the fact that it is recommended to fill the coolant at positive room temperatures. Otherwise, traffic jams may form. Therefore, carefully check what the temperature is in the rooms and house, whether there are frozen sections of pipelines in winter.
- We start the boiler itself strictly according to the instructions, maintaining the required amount of time while holding the start button, otherwise it may not start. For different models, the passports always describe in detail the startup procedure.
- Be especially careful when working with gas equipment, as this is a very dangerous type of fuel, characterized by a low odor and a high explosion hazard. Do not neglect safety measures when working with the device, do not violate the procedure for working with it.
- At the slightest deviation from normal operation, immediately carry out measures to repair and adjust the equipment, including calling a specialized technician.
- Observe the requirements for the installation of the boiler room and ventilation. Your safety in the house directly depends on this.
To summarize, we can say that a gas heating system is currently one of the most popular devices from autonomous heating sources. The economic component is always of interest to the common man. Utility costs take up a significant part of the family budget. The growth of tariffs, with annual indexation, leads to a gradual increase in the level of prices for services to the population.
The consumer tries to find any opportunity to reduce these costs. The cost of natural gas is currently low compared to other energy resources.Therefore, it is profitable to gasify houses and install a heating system that runs on gas. Even if you have to spend a lot of money on it during construction, installation and commissioning, it always pays off later.
