How to start a gas boiler for the first time

Knowing how to turn on a gas boiler, you can do all the preparatory work and start it yourself. You need to be very careful, there may be a gas leak.

Types of gas boilers

Many owners of private houses choose gas boilers for heating. This choice is explained by the economic benefits of using natural fuel and the ability to heat a large house using one device. A gas boiler does not require constant maintenance of the combustion process by adding fuel; during its operation, soot and soot are not formed. There are different types of boilers:

Wall-mounted. They have compact dimensions and light weight, so they can be installed in a small room (kitchen, pantry). A heating system operating through a wall-mounted unit does not require the additional installation of a pump, expansion tank and boiler, so its installation is simple.
Floor-standing. They are characterized by greater power than wall-mounted ones, therefore they are optimally suited for heating large areas. They are equipped with cast iron or steel heat exchangers that have a long service life and are resistant to corrosion and mechanical shock. Floor-standing units can be equipped with both atmospheric and inflatable burners. The second option allows the use of liquid fuel as a raw material.

Gas heaters are also divided into single-circuit and double-circuit. A system with two circuits not only heats the room, but also additionally provides hot water supply. Single-circuit ones do not have such an additional function; in order to have hot water in the house, the system will need to be equipped with a boiler.

Each heating boiler has a combustion chamber. Depending on the design, it can be:

Open. It works due to natural draft, so it is only suitable for rooms with a vertical chimney. Needs effective ventilation, providing a sufficient flow of oxygen and preventing combustion products from entering the room.
Closed. Uses forced traction in work. The presence of an electric fan and a coaxial chimney allows combustion products to be removed from the chamber. All wall-mounted gas appliances are equipped with a closed chamber.

Regardless of the type of gas installation, it is part of a single heating system, which also includes pipes, radiators, a pump, an expansion tank and filters. Before lighting a gas boiler, you need to make sure that the elements are securely connected.

Why does a gas boiler go out and turn off: the main reasons

Setting up the heating system

You can establish efficient and stable operation of the heating system after the boiler has been successfully started.
To set up, you will need to understand the control valves. In most cases, the batteries that are located furthest from the boiler do not have enough heat. This can be corrected if the supply of heated coolant is distributed evenly. To do this, screw in the taps to adjust the first two radiators. The tap of the first radiator needs to be screwed in half, and the subsequent ones a little less. Observe the effect achieved. It may take several days of adjustments and adjustments to get each radiator to heat evenly. However, in general, the system at this stage already works normally and warms the room.

Pre-launch activities

The location for the gas boiler is chosen depending on its modification

The position of the boiler is selected according to safety standards, away from fire hazards. The distance to wall structures is prescribed in the manufacturer's instructions. The body of the unit is set taking into account the horizontal and vertical levels, since if it is distorted, the work is disrupted.

The equipment is connected to the water supply and gas mains, ball valves and filters are installed using pipes. Before lighting the boiler, install the power supply and install a separate socket. First connect the chimney pipe and check for the presence of draft.

What functions does the Zhukovsky gas boiler AOGV 23 have?

The abbreviation AOGV 23 stands for Domestic Gas Heating Apparatus with a power of 23 kW. This is a single-circuit floor-standing unit capable of efficiently heating a room up to 200 m2 .

Such possibilities are optimal for use in a private house, cottage or other premises. The boiler is designed to perform only one function, which allowed the manufacturer to eliminate all unnecessary parts and unused design elements.

This increased reliability and reduced the number of failures and breakdowns. In addition, a feature of AOGV 23 boilers is energy independence.

In the event of a sudden power outage, the boiler will continue to operate as usual, which is important in the Russian winter . This feature significantly increases the reliability of the home heating system.

At the same time, the lack of power supply requires a specific location of the radiator system, since the coolant will circulate naturally.

The combustion chamber of the boiler is atmospheric type, with air intake directly from the room and natural smoke removal using stove-type draft.

Household antifreeze is used as a coolant, which increases the reliability of the heating system in severe frosts.

Filling the system and removing plugs

After installing and debugging gas equipment, you cannot immediately turn it on. Before turning on the gas boiler, the system must be filled with water. To do this you will need:

1. Open the tap located at the bottom of the boiler next to the cold water connection.
2. Wait until the system is filled with water. This happens slowly and requires a certain amount of time. During the process, it is necessary to control the pressure level. To do this you need to use a pressure gauge.
3. When the level of 1.5−2 atm is reached, close the tap.

During filling, air pockets may form inside the system. To prevent their occurrence, the procedure should be carried out at a positive temperature. During the cold season, the room where the boiler is located needs to be preheated.

Even if all the conditions for preventing traffic jams have been met, it is imperative to remove air from the system using air vents specially designed for this purpose, located in the upper fitting of the radiators. Depending on the design of the batteries, these can be Mayevsky taps or automatic valves.

To release air through the tap, you will need to unscrew it using a mounting wrench, after placing a water container under it. Air mixed with water will begin to come out of the radiator. After about 5-7 minutes, when a steady stream of water flows from the tap, it should be closed.

A similar procedure must be done with all radiators connected to the heating system. Then repeated pressure measurements are taken and the water tap is opened. The pressure gauge readings may be slightly above average, but should not reach the maximum. Otherwise, when the water starts to heat up after turning on the boiler, the pressure will become extremely high and the heating system will fail. If you have automatic valves, you won’t have to make any special efforts. You just need to wait a while until the air comes out of the line.

Advantages and disadvantages

Among all the characteristics of the AOGV 11.6 boiler, its main advantages and disadvantages are highlighted. There are several main advantages:

the possibility of using natural and liquefied gas as fuel;
energy independence;
compatibility with any system material;
uninterrupted operation with natural and forced circulation.

The unit can be connected to any heating system. It can be made of cast iron, metal-plastic, polypropylene or steel. That is why such boilers are considered universal. There are also some disadvantages of the devices:

the Economy series is made using outdated parts;
in the event of a breakdown, it is difficult for craftsmen to find suitable parts;
Compared to other units, this version has a fairly high price.

Since Economy boilers are produced using elements made according to samples of Soviet engineers, they are very difficult to replace during repairs. It's better not to buy the cheapest options

, but opt for the Universal. Although, in the case of purchasing models with imported parts, difficulties also arise, since they are not available on the domestic market. You will have to order replacements for damaged elements directly from the manufacturer. The average cost of boilers is 11-17 thousand rubles, which significantly exceeds the price of units from other manufacturers.

Possible startup problems

The gas boiler slams when the main burner starts.

The most common problem, the cause of which is most often clogging of the igniter (dust, combustion products, etc.).
It is recommended to call a specialist to clean it. The reason may also be that the pilot flame is too low: below the main burner. When using electrode ignition, the electrode may be clogged or faulty. In rare cases, the cause may be excess gas pressure in the line. It is important to understand that slight, barely audible pops are characteristic of most models of gas boilers that do not have a sound insulation layer.

Only the wick is lit and cannot light the main burner.

The reason may be the same clogging of the igniter or its incorrect installation, when the flame simply does not reach the main burner. Clean the pilot nozzle (it is advisable to entrust this to a specialist) and check the operation: its flame should reach the main burner and simultaneously “wash” the thermocouple. Sometimes the reason lies in a malfunction of the thermocouple, which does not open the gas supply.

SAFETY INSTRUCTIONS

Persons who have examined this passport are allowed to service the device.

Installation and operation of the devices must comply with the requirements of the “Rules for the design and safety of operation of hot water boilers, water heaters and steam boilers with excess pressure”, as well as the requirements of the “Safety Rules for Gas Distribution and Gas Consumption Systems. PB 12 - 529", approved by the State Mining and Technical Supervision of Russia.

Dear customers, we provide detailed advice to all customers who purchased a boiler in our store.

Starting the device

When all the preparatory stages are completed, you can proceed to launching the gas equipment. The sequence of actions depends on the type of boiler. Attachments such as Celtic, Protherm, Beretta, Ferroli, Bosch need to be connected to the network and the gas valve must be unscrewed. After this, press the “Start” button, using the “+” and “-“ buttons, set the desired temperature.

These models have a hot water supply mode. When switching to it, the electronic burner will automatically light up. To pierce ignition, you will need to press the flame regulator and hold it for a few seconds, then activate the piezo button. Sometimes ignition may be blocked due to air in the system. To unlock, just press the “Restart” key. The inclusion of parapet models of the ATON type occurs according to the same scheme. If the kit includes a remote control, you can set the boiler on fire using it.

The algorithm for launching floor-standing devices will be slightly different. Before lighting a floor-standing gas boiler such as Baxi, Siberia, Buderus, Lemax, Conord, you need to ventilate the room, check the presence of draft and the position of the control and temperature selector. It should be in "Off" mode. Then open the gas valve, switch the selector to the pierroignition mode and press it for 5 seconds. At the same time press the play button. After the burner lights, you can adjust the temperature.

Gas heating systems should not be turned off for a long time, especially during the cold season. The effect of low temperatures will provoke freezing of the heating system and failure of its components (pipes, radiators, boiler). If you plan to not use the gas installation for a long time, it is not recommended to turn it off, but to set the temperature to the minimum. In this way, with minimal fuel consumption, defrosting of the heating circuit will be avoided.

Even if the gas supply from the pipeline stops during the absence of residents, serious problems will not arise. The control sensors that modern gas heaters are equipped with will block their operation, preventing possible problems.

Method for finding a breakdown

First of all, you need to start checking the gas sensor. It is the weakest element of the gas boiler automation system. Due to the fact that the sensor is not protected by a casing, after about a year it becomes covered with a thick layer of dust. As a result, the bimetallic plate oxidizes and thus the contact deteriorates.

Dust can be removed with a soft brush. Next, you need to pull the plate away from the contact and clean it with fine sandpaper. But it is worth remembering that you need to clean the contact. After the contact and plate have been cleaned, a thin layer of liquid lubricant must be applied.

Then it is necessary to check the serviceability of the thermocouple. The service life of this element is much shorter than others, since it is in the pilot flame and is exposed to high temperatures. The main failure of a thermocouple is burnout of the housing. When burnout occurs, the contact resistance at the junction increases. And the bimetallic plate will become lower than the required value and the electromagnet will no longer be able to fix the rod.

Important Operating Instructions

In terms of operation, gas boilers with a closed combustion chamber are considered safer. Their firebox does not communicate with the room air. However, the power of such boilers is significantly inferior to the power of boilers with an open combustion chamber. Therefore, in private households a second type of boiler is often installed.

The choice of future coolant depends on the goals and operating conditions of the system. If the boiler is expected to be turned off frequently, then it makes sense to think about using antifreeze

The operation of such boilers requires compliance with safety precautions. So, to install a powerful floor-standing boiler, it is customary to use a separate room with a certain size. The boiler is mounted at some distance from the walls. Nearby walls should be protected with fire-resistant material to prevent fire.

A ventilation system must be installed in the boiler room. There should also be a source of natural light. The width of the entrance door must be at least 80 centimeters. The chimney is laid in accordance with the instructions for the boiler and from heat-resistant material. The chimney must rise above the roof ridge by at least half a meter.

One safety measure is to install carbon monoxide detectors. The gas detector will promptly detect the leak of a volatile toxin and warn users about it. It can also be configured so that the ventilation is automatically turned on and the gas supply is turned off. Modern automation allows the implementation of a variety of smart systems.

If the temperature, pressure or gas sensor fails, you must immediately turn off the boiler and call a service technician. Using a boiler without these devices is fraught with serious negative consequences.

SNiP requirements state that a gas boiler must be connected to the main line using a copper pipe or a bellows hose. In this case, a faucet must be installed

If signs of a gas leak are detected, you must immediately turn off the gas tap and open the windows to ventilate the room. Do not turn on the light and try to illuminate the room by lighting matches or a lighter.

The gas boiler must be serviced at intervals specified by the manufacturer. Information about the necessary procedures is indicated in the instructions for the device. For example, you need to clean the chimney, remove scale from the heat exchanger, or clear the fumes from the burner. Then the boiler will last a long time, and the risk of serious malfunctions will be significantly reduced.

When using a gas device, do not turn it on at maximum power for a long time. This may result in the release of steam, which is unacceptable.

Sometimes the boiler begins to make unusual noises and vibrations. This may be due to the operation of the fan. We warn you that all actions that require disassembling the boiler casing automatically deprive the owner of the right to warranty repair or replacement.

However, the owner of the unit needs to monitor the operation of mechanisms and systems that protect the boiler from fire. It is necessary to maintain the temperature in the circuits at around 50 degrees, which significantly reduces the likelihood of mineral deposits forming on the internal surfaces of pipes and devices.

Flame and draft sensors

Flame and draft sensors work on this principle. The draft sensor reacts to deteriorating smoke draft and transmits an impulse to the control system. It is located in the smoke hood. Equipped with a plate made of an alloy of two metals: iron and nickel. When draft deteriorates, flue gases accumulate and heat the plate. It becomes deformed, the contacts open, and the flow of fuel into the combustion chamber stops. When the temperature decreases, the plate returns to its normal state.

The temperature sensor works on the same principle. When the water in the boiler heats above the set temperature, the lever mechanism is activated and the temperature regulator valve closes. The gas supply stops and the burners go out.

When the water cools, the sensor bellows contracts, the lever mechanism is activated, the temperature regulator valve opens, gas begins to flow, and the burners light up.

Distinctive characteristics of boilers

The Universal and Economy model boilers are especially popular among buyers. There are significant differences in the technical characteristics of AOGV 116 of these series. The Economy version is manufactured using Russian automation; this unit can be controlled using a solenoid valve and a temperature control knob. A draft sensor and a thermocouple are connected to them - one of the most important elements of the device.

The boiler AOGV 11.6 series Universal is produced on the basis of Italian automatic equipment

. The unit is distinguished by the presence of an automatic thermostat and piezo ignition. The device can be turned on by pressing just one button, and there is no connection to electricity networks.

Winter launch features

If you have to start the boiler in winter, you will need to slightly change the sequence of work:

it is necessary to warm the premises to above-zero temperatures using electric heaters;
fill the short circuit closest to the boiler with coolant;
warm up the coolant to a temperature of 20-23 degrees (no more);
gradually move further along the circuits, heating the coolant to the above temperature;
after all circuits are filled, you can turn on the unit in operating mode.

Care tips and advice

Proper maintenance of the boiler, performed regularly, will help keep it in working condition for a long time and avoid various accidents and accidents. Otherwise, the unit may break even in the first year of operation. Performing several operations will prevent this from happening:

even during normal operation of the boiler, you need to contact one of the organizations carrying out work in this area, so that a technician inspects the device for gas and water leaks, the condition of the sensors and chimney, and, if necessary, carries out repair work;
You should always monitor the water pressure inside or at the outlet of the system. If it drops below 0.8 bar, then water needs to be added;
The addition of water to the system is usually carried out directly through the boiler, where there is a special tap. In this case, the pressure of the added water must be greater than the pressure of water from the boiler. The supplemented water should only be cold (up to 35°C).

For your information! To spend winter evenings warm and comfortable, you need to properly care for your boiler and also know how to light it.

Depending on the model and manufacturer, this process will be slightly different due to differences in design. This can be clarified in the instructions supplied with the device.

Preliminary work

Before lighting a gas boiler, you need to check it for leaks - perform a pressure test. This can be done in two ways: by filling the system with water or using an air compressor. The process consists of the following steps:

open the tap, which is responsible for filling the system with coolant;
slowly fill the radiators with water until the pressure in the system reaches 2 atmospheres;
close the tap and wait about an hour;
if the pressure remains at the same level, then everything is normal; if the reading on the pressure gauge has decreased, there is a leak - you need to find it and fix it.

Checking the air heating system is advisable if you do not intend to use it in the near future. This will eliminate the need to drain water from the system. If, after pressure testing, you plan to put the gas boiler into operation, it is better to immediately fill the radiators with coolant.

Note! Checking the tightness of the heating system can only be carried out if the room temperature is above zero.

Before lighting an old gas boiler that has not been used for a long time, you should thoroughly rinse its heat exchangers, clean the burner device, and also wipe the body.

The heating system is flushed using pressurized water. It is advisable to rinse not only the old, but also the new heating system, since during the installation process debris often gets inside the radiators.

Gas boiler does not reach temperature - causes and methods of eliminating them

Device

The operating principle of the AOGV 23 boiler is based on heating the coolant using an atmospheric burner . Entering the tubular heat exchanger, the liquid reaches its maximum temperature, after which it is discharged into the heating system.

The movement of the coolant occurs under the influence of the upward thermal movement of heated layers, therefore the placement of all pipelines must be planned with a certain slope. To set the temperature to a given value, a three-way valve is installed, which mixes a certain amount of colder return water into the heated coolant.

Natural circulation is unstable and ineffective, so many owners install an external circulation pump to stabilize the system.
