Gas nozzles for heating stoves with automation

A gas nozzle is a godsend for heating a private home. This device has a number of advantages: simple design of the spray device, safety in operation and high efficiency, and therefore its use becomes economically feasible. A gas nozzle for a heating furnace is a device with the help of which a gas-air combustible mixture is created in order to ensure complete combustion of fuel in the combustion chamber. Fuel injectors have a wide range of applications in thermal power engineering. They are installed not only in household stoves, but also in heating boilers of low, medium and high power, operating on gaseous and liquid fuels.

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.

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.

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 ).

Homemade units

There are craftsmen who remake heating systems with their own hands. On the Internet you can even find the necessary diagrams for changing the devices of gas burners, their installation and adjustment.

Typically, metal is used as a material for the manufacture of heating systems. A cast iron firebox would be much more reliable. However, it is not possible to use it at home.

An excellent option for manual work is to order the system from specialists. They will be able to manufacture the device in accordance with all the customer’s wishes. However, the possibility of defects in the boilers cannot be ruled out, which may appear after some time.

Why do you need homemade heating units? The fact is that the marked options have a lower cost. They are made mainly because of the desire to save money. At the same time, these options are inferior to their factory counterparts in efficiency.

Usually only solid fuel and electric units are manufactured. Making a gas or diesel boiler is extremely dangerous. In addition, their installation in the house is strictly prohibited.

According to the principle of operation, a homemade product is no different from a purchased version. It will burn fuel and heat the coolant filled with water.

The main disadvantage of this unit is the lack of warranty. Factory equipment will work and perform its functions. Even if the buyer stumbles upon a defect, he will be able to exchange the product for another.

It is better to use pellets, firewood, and coal as fuel in self-made units. These materials are less dangerous than gas. It is impossible to make heating devices based on the latter.

Simple solid fuel units are the most popular and widespread homemade devices. They are simple, and their design is in many ways similar to a conventional stove. In addition, they are versatile.

Like a conventional stove, these systems can operate on any solid fuel. The main thing is that it burns.

Main parts of a gas boiler.

The efficiency of homemade equipment is significantly lower than factory equipment. It is influenced by many factors.

Among them:

• thermal insulation;
• combustion completeness;
• the correctness of the conclusions.

The efficiency of the unit directly depends on the combustion temperature. The higher it is, the lower the efficiency. In high-quality systems, the temperature in the firebox is maintained at 120–150°C. Higher values ​​reduce the safety of pipes. This in turn significantly reduces the durability of the unit.

When manufacturing heating boilers with a burner, it is better to protect yourself as much as possible from the possible consequences of its operation. Therefore, you should consider a separate purchase of an automatic gas burner, which will be installed in an atmospheric or blown boiler.

You can also make electric heating units with your own hands. Their design may vary. It all depends on the person’s needs. The simplest option is to install a heating element directly into the heating system. In this case, there is no need to make a boiler.

The pipe with the heater must have a sufficiently large diameter. It should be easily removable for repairs and cleaning.

Systems without a heater deserve special attention. Its role is played by water itself. A current is passed through it, and heating occurs due to the movement of water ions. The liquid itself must contain salt.

It is extremely difficult to make such a device. Electric current passes directly through the coolant, so the entire system must be reliably insulated.

One of the dangers of this device is electrical breakdown. Essentially the same as a short circuit. Gas may also accumulate in the system. As a result, heating efficiency will decrease.

From all of the above, the best option is a solid fuel unit. Its body can be assembled from heat-resistant steel. It is characterized by increased strength, less wear and high resistance to thermal influences.

However, heat-resistant steel is expensive and in practice is rarely used in homemade boilers. Another option is cast iron: this material tolerates heat well, although it is difficult to work with. Equipment for the manufacture of cast iron stoves is available only at specialized enterprises.

It is important to understand that without the proper experience and skills, it is better not to make a heating system yourself. Safety must come first

It is enough to make even one inaccuracy, and this can lead to disastrous consequences.

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.

Equipment setup

Floor-standing gas boilers with an atmospheric burner can be configured independently. Pressurized systems are regulated by an automatic control unit and do not require additional configuration.

Scheme of actions for setting up single-stage equipment:

1. Install the device on the boiler.
2. Connect to the gas pipe.
3. Check for absolute tightness.
4. Remove the burner housing.
5. Using a pressure gauge, measure the gas pressure at the inlet.
6. Connect to electricity. Make sure that the jumpers and phases are connected correctly.
7. Place a gas analyzer in the chimney pipe.
8. Start the device.
9. Using a pressure gauge, take pressure readings at the outlet of the burner block. Pressure readings must correspond to the parameters indicated in the data sheet.
10. Adjust the air flow using the air damper.
11. The gas analyzer readings must also comply with all gas equipment installation standards.

Setting up gas equipment should be carried out by specialists. The simplest open-type boilers can be configured independently if you have certain skills and knowledge of the design of the burner unit. The efficiency of the boiler, its level of efficiency, and fuel consumption depend on the quality of the burner. It is possible to superficially determine that the equipment is malfunctioning by the changed burner flame.

A heating system where the main element is a gas stove is a common type of heating for private households and cottages. There are many things in favor of natural gas as a heat source: high efficiency, environmental friendliness, and the ability to make the heating process fully automated. The fuel itself is also the most inexpensive at present, unless, of course, you take into account wind energy and solar radiation. But these methods have not yet found wide demand due to the unaffordable price of the equipment.

The quality of gas heating depends on how efficiently the gas burner for the stove works.

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.

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.

Characteristic

An acetylene welding torch is a special device into which a special gas (acetylene) is supplied for combustion. It is used more often than other devices for gas welding. The reasons for its popularity are quite obvious:

suitability for work even with a limited set of equipment;

high efficiency of application (justified even at nuclear and other critical facilities).

The combustion temperature of acetylene is higher than that of any other welding gas. It reaches 3200 degrees. The reason is that the acetylene combustion reaction is endothermic, while other gases absorb heat during the decomposition process. Complete combustion of 1 cu. m of this gas will require the use of 2.5 cubic meters. m. air. These are the calculations carried out by chemists based on the formulas of the reacting substances.

However, in practice, acetylene burns only incompletely in a flame, so during real welding the air consumption does not exceed 1-1.2 cubic meters. m. Because of this, the total useful heat productivity, instead of the theoretically calculated 13500 kcal per 1 m3, is only 5120 kcal per 1 m3. In practice, an oxygen-acetylene mixture is most often used, in which 55% is acetylene, and the remaining 45% of the mass is oxygen.

It is also useful to understand how an acetylene torch differs from a propane torch in practice. The first type is mainly used for working with relatively thin (no more than 6 mm) metal. The tips of the burner devices contain, in addition to the injector, also a mouthpiece and a tube. The proportions of the holes in the mouthpieces and injectors are calculated strictly individually for each gas used. Therefore, to replace the gas, you have to use a different tip, preferably from the same manufacturer.

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.

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.

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.

How to choose a good device?

The main characteristics of such products are:

When choosing a device, you need to keep the following factors in mind:

• Simplicity of design. In this case, the cross-sections of the paths for the passage of gas must be the same and create minimal resistance to the gas.
• Room size. For small rooms, an atmospheric device will be sufficient, but for larger rooms the power of such devices may not be enough.
• Manufacturer of the product. Domestic and foreign (mostly products made in Germany are on the market) units have approximately the same cost, but some similar devices are designed for installation in specific types of stoves. For example, the domestic product AGG-15 is suitable for use only in stoves with a long channel for the fuel mixture.

Photo 2. Gas nozzle AGG-26, suitable for furnaces with a long channel.

• Type of heating device.

Important! You need to know where the fuel will come from to the heating device: from individual cylinders or from the main pipe. This is also taken into account when installing the stove.

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:

1. 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.

2. 
   The fan provides the combustion process with the air necessary to burn the fuel.

3. A solenoid valve is a valve that operates automatically. It is used to supply a jet of fuel in sufficient quantity for combustion.
4. 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.
5. 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.
6. Electrodes, they allow you to ignite the gas-air mixture to create the desired flame.
7. 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:

1. Pre-ignition. Turning on the fan, which allows the engine to run.
2. Ignition. Opening of the solenoid valve, which directs fuel to the nozzle.
3. Ignition. A spark is created to maintain a stable combustion flame.
4. Operating mode. Turn off the igniter after the flame has stabilized.
5. 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:

1. Having a combustion chamber. The gas enters the heating chamber and, when burned, heats its walls.
2. 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:

1. 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.
2. 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.

Combustion chamber of heating equipment

Gas boilers differ primarily in the design of the combustion chamber. It comes in two types:

The open chamber is a fairly simple combustion device. It looks like this: above the burner there is a heat exchanger in the form of a coil of thin copper tubes. Thanks to the open design, the air required for the combustion reaction is supplied to the point of ignition of the gas from the environment.

As a rule, there is enough air from the room (provided good ventilation is organized). But there are wall-mounted models with air intake from outside, for which a special hole is mounted in the wall. Open combustion chambers require a chimney.

Most often it is installed for models of floor-standing gas boilers, and was also used to complete an old-style boiler (in this case, ignition was carried out by a pilot burner).

Combustion chamber design diagrams

The closed combustion chamber is distinguished by the design of the heating block. The heat exchanger is located above the burner. The unit body is closed, combustion air is pumped by a fan installed in the chamber. Coolant is passed through the double walls of the chamber, heating it, increasing the efficiency of the boiler. The gas is burned almost completely, the combustion products are removed by a coaxial pipe under air pressure.

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.

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.

Product cost

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.

Ignition type

All burners can be divided according to the type of ignition:

1. 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.
2. 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.
