The burner of a gas boiler converts the chemical energy of the fuel into the thermal energy of water, which is supplied to the heating and hot water supply system of the house. Gas burners for heating stoves are installed in special devices called boilers. The correct choice of burner device will ensure not only a comfortable living environment in the house, but also its safety.
Purpose and advantages of nozzles
Gas burners (or nozzles) are designed to operate the stove on gas. Like other similar devices, the nozzle mixes fuel - natural or liquefied gas with air. As a result, the temperature in the oven increases.
Most often, such gas products are installed in baths , where high temperatures are required for a long time. However, nothing prevents you from installing a nozzle in your home in order to save yourself from the usual methods of kindling. In addition, such products have a number of significant advantages:
- Safety. Since such products work with explosive material, they are subject to strict requirements regarding reliability. You can verify this by reading the quality certificate.
- Availability of automation. Most gas products are equipped with automatic temperature control , which provides not only economical fuel consumption, but also protection from overheating or explosion of the furnace.
- Economical. As you know, gas is much cheaper than the cost of firewood, coal or electricity.
- Variety of fuels used. Many devices can operate on natural or liquefied gas.
- Ease of operation. The operation of gas devices for furnaces does not require any specific skills. In addition, some models can be operated from a special remote control.
- Ergonomics. Storing coal, firewood or other flammable materials requires a lot of space. The supply of fuel to the injector comes from the gas column.
Trouble-shooting
Having a boiler at home brings many advantages, but it also has a number of disadvantages, and the user does not always know what to do correctly. Boiler faults are common to many types. It is important to promptly determine the cause of these faults before calling emergency services. List of the most common and most likely faults.
First of all, if the boiler does not start, you need to check the circuit components:
- network voltage;
- faulty boiler fan switch or motor;
- damaged boiler cables;
- false triggering contacts of automation or commissioning equipment;
- availability of water, whether the gas boiler is powered to the minimum required level specified by the equipment manufacturer.
If the boiler failure is not caused by any of these problems, the following procedure:
- Pay attention to the noises made by the boiler, because they are often the first witnesses of destruction. They can also be due to hot water trapped inside the firebox or due to the presence of air in the heating system due to clogged air ducts.
- Pipe rupture. It usually occurs due to problems with a jammed boiler feed valve, various scale-forming deposits in the boiler, or a malfunction of the condensate drainage systems.
- Failures due to exceeding the pressure and temperature readings, their corresponding sensors can trigger, for example, due to a broken thermometer or, conversely, which is especially dangerous as a result of real overheating of the boiler.
- The heating circuits are not working, possibly due to poor quality of feed water and scale formation in the boiler pipes.
- A problem occurs with the burner (flame breaks, gas accumulation causes detonation and explosion).
For some of these problems, mainly pressure or temperature, the boiler monitor displays an error message, then the system shuts down and automatically restarts. If the problem persists after restarting, it is best to call a professional to troubleshoot the problem. It should be noted, however, that most of these failures can be avoided.
The best prevention is to have your boiler inspected, maintained and cleaned annually, usually by a professional. This will prevent the pipes from clogging and bursting. Prevention is better than restoration, and a simple annual inspection will protect the equipment and the health of users from possible emergency situations.
Principle of operation
There are 2 types of such devices on the gas burner market:
Atmospheric nozzles draw air from the room where the stove is located. In addition, the operation does not require the use of complex automation. Thanks to this, the product has a simpler and more uncomplicated design. The main drawback is the requirement for good air circulation. Therefore, atmospheric burners should be installed in well-ventilated areas. However, some models have special sensors that monitor the oxygen level and, if its content is low, turn off the gas supply.
Supercharged products are equipped with complex automation , due to which they have a more complex design. Such products operate on the principle of forced air injection. Fans are responsible for this, regulating the pressure and volume of supplied oxygen. The main requirement for use is that air must be taken from the street.
Space heating devices
They mix fuel and oxygen and, with the help of an ignition device, ensure complete combustion, which occurs in the combustion chamber, and the heat is transferred to water through a heat exchanger. Control devices regulate ignition, combustion speed, fuel and air supply, exhaust draft, water temperature, steam and water pressure in the boiler.
The hot water produced by the boiler moves through natural circulation through the in-house heating system of the entire building. The heating circuit may include hot water heat exchangers, air conditioning and ventilation units.
Type of fuel used
Everything is much simpler here - the device can run only on gas or use several types of fuel. The first option is the simplest type of gas injectors and is the most popular in comparison with its “competitor”. As a rule, such products are installed in houses or apartments where there is a gas supply.
The second option has a more complex design, but can work with several types of fuel:
- liquefied gas;
- natural gas;
- diesel fuel.
Of course, the cost of such varieties is higher. Therefore, they are more often purchased in cases where gasification of the house is planned in the near future.
First start
Before starting the gas water heating boiler for the first time, it is necessary to check the correct installation and installation, in compliance with all instructions. The installed boiler must be inspected by a gas service inspector and sealed. After which you can begin preparing for the first launch. Before starting, the automation is configured with the required parameters set, following the operating instructions supplied with the boiler.
Filling the system with coolant
Step one is to fill the system with water or another coolant. The entire circulation circuit is checked for the presence or absence of “air” plugs in the system.
If present, air pockets must be vented by slowly releasing air through a special valve. Most often this is found on heating elements.
Etching should be carried out with caution, with the readiness to close the valve in time
Checking the supply lines
Step two is to check gas pipes, valves, and shut-off valves for leaks. The inspection is carried out by a gas service employee. But if you smell a specific gas smell, you can check it yourself before a specialist arrives and find the leak. For this, use a regular soap solution.
By applying it to welds, at the joints of pipes and shut-off valves, you can detect gas leaks.
Putting the boiler into operation
Step three is the direct start of the gas water heating boiler itself. Carry out strictly according to the attached instructions. If you can’t figure it out on your own, then it’s better to contact specialists who have access to this type of work.
Boiler shutdown
At the end of the heating season, if the boiler is not planned for use in the hot water supply system, then it must be turned off for a long period. To do this, follow a few simple steps:
- turn off the gas supply, make sure that the burner in the boiler goes out completely;
- turn off the power supply to automatic ignition and automation;
- shut off the water supply to heating and water supply.
No special additional actions are required. Do not drain the entire coolant circulation system to avoid corrosion.
Important points when choosing a nozzle
Sales consultants can help you choose a gas burner. But as you know, rely on others, but don’t make a mistake yourself. Therefore, it is recommended that you familiarize yourself with a number of points before purchasing.
- Features of the premises. First of all, this is the area. If it is less than 12 sq. m., then it would be more reasonable to buy a supercharged type, if larger - atmospheric. Ventilation also plays an important role. If the speed and volume of air circulation leaves much to be desired, it is worth purchasing a forced-air gas burner.
- Oven type. If the stove runs only on gas, you need to purchase an atmospheric version. In other cases, the supercharged variety is perfect.
- Power. The expression “the higher the power, the better” does not apply here. This value should be calculated based on the area of the room. So, for 10 sq. m. requires 1 kW of energy.
- Manufacturer country. When choosing gas equipment, you should remember that foreign products are of higher quality and more durable than domestic ones. Therefore, first of all, it is recommended to pay attention to American, German and Italian injectors.
Purchasing a gas injector will first of all help strengthen your financial situation, and only then free you from constant running around with firewood or coal. A gas stove is a very convenient and practical invention , but you must remember about the explosiveness of this fuel. Therefore, you should not purchase the cheapest and low-quality products.
Why is it prohibited to use gas nozzles in furnaces? These kinds of questions have been regularly coming from visitors to EnergoVOPROS.ru over the past few months. Gas workers are demanding that the burners be dismantled and full-fledged gas boilers installed. Why is this happening? Have there been any changes in legislation? We are publishing clarifications on this matter, which were given by gas workers of the Republic of Bashkortostan.
Gas workers prohibit using a stove with a gas burner (nozzle). Why?
The Public Electronic Newspaper (published in Bashkiria) received an appeal from residents of the village of Arslanovo, Buzdyak district of the republic. They reported that representatives of the gas service of the Buzdyak district are now carrying out repair work in the village. And they demand that all residents who still have brick stoves with a gas burner (nozzles) installed inside, immediately demolish these stoves. Otherwise they threaten to not connect the gas heating. Residents do not understand what law or document this requirement is based on, since this is not explained to them.
These journalists forwarded their questions to the local gas supply organization Gazprom Gas Distribution Ufa. A company representative said the following in response to an inquiry:
— The populated areas of the Buzdyaksky district were supplied with gas by collective and state farms in the 80-90s of the last century. And to do this quickly, they installed gas burners on existing wood stoves. They simply installed a burner without automation. And now this equipment does not meet the requirements for indoor gas equipment. They do not have automatic controls for traction or flame extinguishing. Their efficiency is low, and as a result, people overpay. And the service life of these devices has already expired twice - depending on the brand of the device, the service life ranges from eight to 15 years. Many accidents are recorded in houses with such stoves - people get burned, houses burn down due to overheating of the stove. Therefore, we recommend that residents replace their stoves with boilers. We offer them to purchase equipment and pay for installation in installments of up to six months, concluding an agreement directly with us, without banks. We work directly with factories, so our prices are not very high - from ten thousand. Many people enter into such agreements. For example, in the Tuymazinsky and Bakalinsky districts, stoves are being removed and equipment is being replaced everywhere.
In the Buzdyaksky district, for the second year now, we have been issuing orders to replace gas equipment with expired service life. And if residents do not comply with this instruction, then we have the right to turn off gas equipment.
According to a representative of Gazprom Gazoraspredelenie Ufa JSC, the organization in this case acts in accordance with the Decree of the Government of the Russian Federation of May 14, 2013 N 410 “On measures to ensure safety when using and maintaining indoor and indoor gas equipment” (with amendments and additions ).
Methods of supplying gas to the stove
There are two ways to gasify a bathhouse:
- From the citywide system.
- Individually using a balloon.
Gasification from the city system
Gas can be supplied to the bathhouse from the city pipe.
If a gas pipe runs through the area, then it is more profitable to power the bathhouse from it. Let’s say right away that this is a labor-intensive task and requires knowledge and permissions. The price for the services of specialized companies is high, but once you supply gas to the bathhouse, you won’t have to worry about it for many years. And paying gas bills will be less expensive than purchasing bottled fuel each time.
For urban gasification it is necessary to carry out a number of measures:
- Receive and approve a number of documents: gas supply project, agree on technical conditions and draw up an estimate.
- Purchase equipment and pipes and carry out installation.
- Prepare test and technical documentation and submit the work to the local gas service.
- Get into the system, install and register the meter, start it up and receive documents for maintenance and fuel supply.
It’s difficult to do all of the above points on your own; it’s easier to call a specialist. Moreover, the city gas company itself will provide and install pipes to the heating device.
Individual gasification
You can power the stove from a gas cylinder, which comes in different sizes.
Individual gasification is suitable for areas where there is no city line. A gas cylinder can be purchased at any specialty store. But such gas supply is quite unsafe.
Safety comes first, the cylinder should not be installed in a bathhouse, its place is outside. The place chosen is easily accessible and ventilated, that is, the cylinder cannot be filled with various objects or covered with things. A fire extinguisher is hung nearby or a small box of sand is installed.
Purpose and advantages of nozzles
Gas burners (or nozzles) are designed to operate the stove on gas. Like other similar devices, the nozzle mixes fuel - natural or liquefied gas with air. As a result, the temperature in the oven increases.
Most often, such gas products are installed in baths , where high temperatures are required for a long time.

- Availability of automation. Most gas products are equipped with automatic temperature control , which provides not only economical fuel consumption, but also protection from overheating or explosion of the furnace.
- Economical. As you know, gas is much cheaper than the cost of firewood, coal or electricity.
- Variety of fuels used. Many devices can operate on natural or liquefied gas.
- Ease of operation. The operation of gas devices for furnaces does not require any specific skills. In addition, some models can be operated from a special remote control.
- Ergonomics. Storing coal, firewood or other flammable materials requires a lot of space. The supply of fuel to the injector comes from the gas column.
How to install it yourself?
It is extremely important: independent installation of gas systems, including installation of burners in a household or industrial oven, is prohibited for non-specialists. In such actions, people take full responsibility for the consequences.
First you need to make sure that the installation itself is possible. Check that the length, geometry, and temperature of the flame correspond to the firebox material. The fire must be free in the combustion chamber, without contacting the walls.
Next they check to see if there are any cavities, cracks, or problematic seams. They can contribute to the contamination of room air with combustion products. The installation procedure itself is as follows:
- remove the combustion door;
- insert the burner;
- attach the shield to the door frame;
- connect the automation, which is then used for configuration.
The connection of automatic systems must be carried out in strict accordance with the original instructions. To complete the work, connect the burner device to the hose. At the opposite end, a gas pipeline or cylinder reducer should already be connected.
Gas service professionals evaluate the operation of nozzles, adjustment devices, and safety automatics. Additionally, sensor activity is configured and tested. When installing it yourself, this is no less important. When installing a gas burner in an industrial furnace, a remote control and a thermal cylinder are installed. Immediately after this, all joints and drafts in the chimney are inspected.

A gas stove is a very convenient and practical invention , but you must remember about the explosiveness of this fuel. Therefore, you should not purchase the cheapest and low-quality products.
Foundation
Ideally, when constructing a building, the foundation for the furnace will already be laid. Until recently, this is exactly what they did in the villages. What to do if there is no foundation? Let's build it with our own hands.
You need to dig a hole, the perimeter of which will be slightly (see 15) larger than the perimeter of the stove. The bottom of the pit is covered with sand, and the sides are reinforced. Then the concrete mixture is poured.
The concrete must harden well; up to 2 weeks are allotted for this. When working, check the surface with a level; it must be flat and strictly horizontal and 10-16 cm below the main floor. A roofing felt sheet folded in half is placed on top, then a steel sheet and an insulation bedding.
For stoves used in outdoor dachas, the foundation is not deep and just above the ground. The same applies to stoves that will be in the garden.
Purpose and types of jets
Natural gas NG G20 is mainly supplied to kitchens through city pipelines. It is supplied directly to the stove under a pressure of 20 mBar. In places where there is no gas pipeline, bottled gas, also called liquefied gas, is used. The most common of them is LPG G30. The pressure at the outlet of the cylinder is 50 mBar.
Due to the difference in the composition of the gas and its pressure when entering the furnace, the combustion of the gas-air mixture is significantly different. To even out the flame on the burner and avoid harmful soot, a jet was created. It is a regular threaded bolt, but only with an internal hole. People often call them injectors or nozzles. Their main difference is the caliber of the hole through which fuel is dosed.
Converting a stove to propane-butane is not the only reason when nozzles need to be replaced. You should also install other nozzles if on the stove burner:
- soot appears and the fuel burns unevenly;
- the flame comes off the burner and a hissing sound is heard;
- The color of the flame is yellow-white, instead of blue.
Any of these actions indicates that the stove has inappropriate jets.
Pulse burner design
It has a higher efficiency compared to natural ones, is more efficient and complex in design. The fuel burner consists mainly of seven elements:
- Fuel pump, it supplies the boiler with fuel from the tank (liquid fuel) and is equipped with a pressure regulator that returns the excess fuel required for combustion.
- The fan provides the combustion process with the air necessary to burn the fuel.
- A solenoid valve is a valve that operates automatically. It is used to supply a jet of fuel in sufficient quantity for combustion.
- The nozzles are the central part of the burner. The nozzle allows the fuel to be atomized very finely to promote thorough mixing with air to form a fuel-air mixture for combustion.
- A fuel heater, it allows the liquid fuel contained in the tank to be made less viscous to aid combustion. This initial viscosity is related to the storage temperature in the tank as well as the specific characteristics of the fuel.
- Electrodes, they allow you to ignite the gas-air mixture to create the desired flame.
- The combustion head, which consists of two elements. The tip that directs the flame and the reflector that holds the flame in the stove.
The burner operating mode can be divided sequentially into stages:
- Pre-ignition. Turning on the fan, which allows the engine to run.
- Ignition. Opening of the solenoid valve, which directs fuel to the nozzle.
- Ignition. A spark is created to maintain a stable combustion flame.
- Operating mode. Turn off the igniter after the flame has stabilized.
- Stop. Closing the solenoid valve, turning off the burner and after 15 - 20 minutes of ventilation of the firebox in order to free the combustion space from explosive mixtures, turning off the fan.

Gas stoves are used to heat households and country houses, but such devices have gained the greatest popularity in the construction of bathhouses. Most often, for this case, they buy factory-made units that have a metal body. In this case, you need to choose the right model in terms of power and purpose, taking into account the operating conditions. Brick ovens are also being built.
Based on the method of generating heat, furnaces can be divided into two types:
- Having a combustion chamber. The gas enters the heating chamber and, when burned, heats its walls.
- Furnace with heat exchanger. In the designs of these heating units, gas enters a curved, heat-resistant steel tube, which acts as a heat exchanger.
In the second case, the furnaces are additionally equipped with a system of forced air supply and exhaust of combustion products.
Gas furnaces are distinguished by heat capacity. This indicator depends on the ability of the unit to accumulate heat.
According to this parameter, furnaces are divided into the following categories:
- Constant burning furnaces. They have thinner walls that cool quickly enough. However, there is a significant plus - they warm up the room just as quickly, releasing heat outside. In order to maintain a constant comfortable temperature in the room, the stove must be in the “on” mode. This is a typical country house option. You can come and immediately warm up.
- Batch furnace. This is a massive heat-intensive structure that is capable of giving off heat even after the gas is turned off. In order to retain heat, the channels and combustion chamber are lined with clay bricks. It is very convenient to install such stoves in baths. They will warm up the stones in a short time and begin to give off heat for a long time. For heating households, this option is also more acceptable.
Stove gas burners, which are installed in the stove of a household or a country house, are similar to each other. They have a combustion chamber (heat exchanger), a housing, a smoke exhaust system, channels for heated air and an automatic unit.
However, there is one obligatory part that has its own characteristics in each case - a gas burner for the stove. It is she who is responsible for the efficiency of the heating unit, power characteristics, economical fuel consumption, safe operation and other important parameters.
Single-stage atmospheric gas burners for a home stove are not difficult to use, they are easy to install in a heating unit. They don't need electrical power. This burner is placed on the front side, where the combustion door is located.
What should you pay attention to?
To properly build a stove for your home or bathhouse yourself, you must follow certain subtleties. Whether you are building a small or large oven, pay attention to:
- For reliability, the brickwork of the stove is secured with the so-called bandaging of seams. Bandaging is alternating bricks with different sides. For example, the bottom brick is placed with the long (spoon) side forward, the middle one with the short side (called the butt side), then again with the spoon side. The dressing can be single-row or multi-row. Multi-row is more reliable and economical; it requires fewer incomplete bricks. Vertical dressing is required! Horizontal is desirable.
- All seams, both horizontal and vertical, are coated with the solution.
- It is recommended to lay the bottom row with the brick surface facing forward; this will reliably strengthen the entire structure.
- The thickness of the seams between the stones should be up to 3 millimeters, but not less than 2 mm.
- No need to tap the bricks! Put them in place immediately, with clear movements. Moving stones or moving them is not allowed.
- If the stove is located in the house, calculate its position so that it does not come into contact with flammable surfaces. When building a stove into a wall, cover the opening with brick and metal. Seal the gap between the stove and the opening with non-combustible insulation.
- When installing metal equipment, the edges of the bricks are cut off. The gap between the cast iron and the brick is about half a centimeter. Then it is filled with a mixture of concrete and sand. This is done because metal and brick have different deformations when heated.
- Around the holes and doors, brick can be laid edgewise. This will give the whole building a certain charm and also strengthen the structure.
- For a gas firebox, install special ready-made gas burners. They must meet all safety standards and have degrees of protection: when the flame is blown out or flooded, the gas supply must automatically stop.
Replacing injectors
A specialist from the gas service will be able to change the jets efficiently and professionally. He has the necessary knowledge and qualifications to correctly adjust the gas supply when switching to another fuel. Especially considering that to use bottled gas it is necessary to additionally connect a reducer. But if you rely on the data contained in the correspondence table, then a home master can confidently cope with such work.
Below in the table you can find the required diameter of the gas nozzle depending on the fuel used.
Burner type | Gas type and pressure | |||
NG G20 (20 mBar) | LPG G30 (50 mBar) | NG G25 (20 mBar) | LPG G30 (30 mBar) | |
Small | 0.75mm | 0.43 mm | 0.70mm | 0.50 mm |
Average | 0.92mm | 0.55 mm | 0.92mm | 0.65mm |
Big | 1.15 mm | 0.60mm | 1.15 mm | 0.75mm |
Oven burner | 1.20 mm | 0.65mm | 1.15 mm | 0.75mm |
Grill burner | 0.95 mm | 0.60mm | 0.95 mm | 0.65mm |
On the burners
For those who decide to change the jets with their own hands, below is an algorithm of actions that must be followed:
- to gain access to the burner, you need to remove the top cover of the gas stove, which is secured with screws;
- then you should remove the tips with nozzles from the traverse with the burners, for which you first need to find the latch (outwardly resembling a clothespin), effortlessly squeeze its ends and carefully remove it;
- Next, the tip should be released from the socket and removed from the gas pipeline tube;
- an O-ring will remain in the tip, which needs to be removed from there and put back on the tube;
- the next step is to carefully unscrew the jets using a socket wrench counterclockwise (if the nozzle is stuck and does not budge, it is recommended to use a vice);
- and finally, new nozzles need to be screwed into each tip, and then reinstalled.
Due to the low pressure in the network, sealing the threaded connection is not required. How to lubricate the o-ring. How smoothly the burner will burn depends on how carefully and correctly the reassembly of the structure is carried out.
In modern gas stoves, the process of converting to use other fuels is even simpler. To get to the burners, you only need to remove the grates with the burners. After this, you can easily remove the tips and replace the jets with new ones.
In the oven
To change the jets in a gas oven, you need to follow these steps:
- open the oven door and the lower oven compartment completely;
- pull towards you and pull out the floor of the oven compartment;
- unscrew the fastenings of the gas burner and move it to the side;
- a nozzle is hidden in a special housing on the left (if the stove has not been in use for long, the nozzle will easily unscrew from this position, and if the nozzle has become stuck, then you need to continue disassembling so as not to strip the thread);
- remove the left side wall by unscrewing the three fastening screws;
- Using a 17mm wrench, unscrew the nut and move the pipeline to the side;
- unscrew the last two screws that secure the nozzle body to the wall;
- treat the stuck thread with kerosene or WD-40 and use a vice for convenience when unscrewing the jet (if necessary);
- install a new injector.
Then you need to carefully install the oven in the reverse order.
Masonry
Each stove has its own design features. Its construction must exactly correspond to the drawings. Let's figure out how to build a brick oven and give the average stages of construction:
- It is always correct to make the bottom row continuous. It is the basis of the stove, so close attention is paid to it: the corners must be clearly straight, the verticality of the walls is checked with a weight.
- The second and subsequent rows are made in strict accordance with the drawings. Sometimes, the second row is also laid solid, sometimes a door for the blower is placed in it, and sometimes it is placed next to it higher.
- To make it easy to remove ash, trim the edges of the bricks immediately at the construction stage so that they form a cone.
- When placing the grate, make a small niche for it so that it is slightly in the recess - this will have a positive effect on the efficiency of the stove. Leave a small (few mm) gap between the grate and the bricks. It will be filled with sand and concrete.
- When building a firebox, it is important to combine materials correctly: the inner surface is made of fireclay bricks, the outer surface is made of ceramic bricks.
- A cooking surface is built into the upper rows, if necessary. For it, it is better to take fireproof fireclay bricks.
- Keep track so you don't accidentally block your channels! After several rows, a damper and a ventilation door are formed.
- In the upper rows, the chambers begin to overlap: first the cooking chambers, then the thermal chambers. The top row of bricks covers all channels except the smoke channel.
- The chimney is removed. To do this, in the places where it passes through the floors and roof, gaps are left, which are filled with special insulation. A steel sheet is strengthened around the hole and secured with self-tapping screws to avoid accidental fire.
- For reliability, the stove can be tied with metal ties.
- After all work is completed, allow the structure to dry and settle. It is recommended not to heat the stove for about two weeks after building it yourself.
This is a rough plan for how to build a brick oven yourself. Carry out all work in accordance with safety precautions. Remove any remaining solution immediately. Plastering of internal surfaces is not allowed.

From the above it follows that the operation of changing jets is not difficult and is quite within the capabilities of any person without special education. And installing the right nozzles will not only save gas fuel consumption, but will also rid the room of soot and unpleasant odors.
Safety regulations
Frequently encountered dangerous malfunctions and methods of elimination according to safety rules:
- flame failure is a moment during which the flame extinguished, but the gas supply did not stop. The solution is to turn off the gas supply and open the room in which the boiler is located for ventilation. During ventilation, it is strictly forbidden to use open fire, turn on and off electrical appliances, lighters, etc.;
- decrease in the filling of the circulation circuit with water - occurs when there is a water leak. If a leak is detected, turn off the boiler, but under no circumstances start filling the circulation circuit. Wait until it cools down completely, find the leak, and fix it. After which you will have to fill the circulation circuit again;
- the draft in the chimney has disappeared - stop the boiler, clean the chimney. Ventilate the room. When the draft resumes, return the boiler to operation;
- The pilot light goes out - turn off the boiler, carry out the switching procedure according to the passport and the attached instructions.
Ignition type
All burners can be divided according to the type of ignition:
- Electronic type. They do not have a constantly working igniter. Requires electricity to operate. Electric ignition is one of the most convenient inventions for modern heating units. Thanks to him, the operation of the stoves has become as comfortable as possible. Electric ignition makes it possible to light the burner flame safely, without using available wicks or lighters.
- Burners with piezo ignition. No electricity needed.
Sometimes special working conditions are required, for example, burners are placed in a sauna stove, which must distribute the flame well. These are dividers or ordinary distribution tubes. This is how kitchen gas ovens work.
The fuel consumption passing through the burner can vary widely and depend on its design.
Gas burners for your furnace should be safe and energy efficient. This can be achieved if all technical requirements are met. Self-indulgence in this matter can only do harm. Therefore, the installation of gas burners must be carried out by specialists.
Modernization of heating equipment
Any home craftsman can install a homemade atmospheric gas burner for a sauna stove. So, without any special costs, a solid fuel boiler can be converted into a gas one.
Equipping an existing solid fuel stove in a sauna with a factory-made gas burner unit will require some adjustment. You will be faced with the need to modify the dimensions of both the burner and the combustion chamber of the wood-burning stove.
To heat the combustion chamber evenly, the burner should be positioned closer to the bottom of the stove and strictly in the center. It is unacceptable to place the source high and offset in any direction. In this case, the camera will not warm up completely. And the flame from the burner can touch metal parts or the heater of the sauna stove.
