A simple gas burner differs from one with a thermostat. Burner designs. Additional oven location

The operating principle of a gas boiler is based on heating the circulating liquid passing through a heat exchanger. Heat is generated in the combustion chamber as a result of the operation of the gas burner of the heating device. The productive capacity of the boiler and its efficiency depend on the quality settings and then the operation of the burner. Let's consider the main aspects of choosing and setting up a gas boiler burner in more detail.

How to choose?

What you need to pay attention to when choosing a burner device for a boiler:

- productive capacity
— noise level during operation (applies to supercharged models)
- type of heating equipment for which the burner is purchased
- type of fuel
- pros and cons of this device
— provide for possible disruptions in the operation of the local gas supply line.

Taking these factors into account, you can choose the most suitable burner device for your boiler so that it operates as efficiently as possible without the burden of frequent preventive maintenance.

Combustion chamber of heating equipment

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

• open;
• closed.

Open The 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

Closed The combustion chamber differs in 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.

Types of burners

According to their design and functional differences, burner devices are divided into:

By purpose:

• for high power industrial equipment
• for household equipment.

By fuel type used:

• devices for natural gas;
• devices for liquefied gas;
• universal devices.

By flame adjustment:

• single-stage – capable of operating on/off;
• two-stage (as a variation - models with smooth modulation) - operate at full power, when the desired temperature is reached, the flame is reduced by half;
• modulating – boilers with a modulating burner are different smooth adjustment the power of the flame.

According to the operating principle:

Gas burner device for a boiler

Atmospheric and fan burner devices differ in their structure. This is due in different ways supplying oxygen to the chamber during fuel combustion.

Atmospheric burner device.

Air enters the combustion chamber directly from the room. Nozzles are located inside the burner channel. Gas is supplied to the nozzles, mixing with air, which also has access here. On a short distance From the nozzles there are outlet slots through which the finished fuel mixture is supplied. An area is created between the nozzles and outlets low blood pressure, which contributes to the constant injection of air for mixing.

A pilot burner is constantly running in the combustion chamber to ignite the main device.

Fan burner device.

The device block consists of:

1. engine;
2. fan;
3. automatic control unit;
4. gearbox;
5. air pressure switch;
6. fuel mixer.

Air is forced from outside by a fan and supplied to the combustion chamber to form a fuel substance. The air to gas ratio can be adjusted using a damper and a fan.

Burner flame

One of the indicators of proper burner operation is the color of the flame. Gas equipment is characterized by an even bluish flame without admixtures of other colors. The presence of yellow or red splashes indicates that the burner is not working well, which reduces the efficiency of the heating equipment.

First of all, this applies to injection burner devices, but sometimes it is also typical for fan burners. The flame may simply lack oxygen. Also, dust and other small debris can get in with the air, which will clog the device, reducing the efficiency of the boiler. All this directly affects the flame. If it hums, the burner is loud, or the fire has changed color, you need to adjust the correct operation of the device.

In what cases is it necessary to adjust the burner flame?

An atmospheric gas burner for heating equipment often fails. It is equipped with models of both wall-mounted and floor-standing boilers. The injection burner of floor-standing equipment reduces its efficiency for various reasons:

• Burner power is too high. This happens when a high-power burner is purchased for small heating equipment. At the same time, there is not enough space for combustion, the air flow for such power is weak, which leads to the transition of the flame from blue to yellow, sooting of the combustion chamber and chimney.
• If the chimney is poorly cleaned, the boiler draft deteriorates. At the same time, waste combustion products are poorly removed, and the air flow is small. This worsens combustion and the flame turns yellow.
• A defect in the burner itself does not make it possible to correctly adjust the complete combustion of the fuel.
• Due to pressure changes in the gas supply system, well-regulated equipment can emit a large number of unexhausted gas into the chimney. Partially it settles with soot and soot. A large layer of soot reduces traction and increases fuel consumption.
• Starting heating equipment after repair.
• The presence of extraneous noise during operation of the boiler or gas burner.
• Changing the type of fuel.

Equipment setup

Floor-standing gas boilers With an atmospheric burner you can set it up yourself. 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.

Gas heating of industrial and residential premises occurs under automatic control. Today's technologies make it possible to carry out precise regulation necessary temperature regime, and at the same time saving on fuel. This result was achieved through the use of burners with a power control option, which is ensured by the automatic operation of the gas burner.

An automatic gas burner for a boiler is a device that mixes gas with air and burns this resulting composition in a combustion chamber.

How does the automatic temperature control system work?

The most simple system Automatic regulation of the set temperature using a gas burner works like this: gas is supplied to the burner, which is ignited by the ignition function, and thus constant combustion occurs. At the same time, the burner itself operates at full power. When a certain temperature of the coolant or air in the room is reached, the automatic gas burner extinguishes the fire.

To maintain the set temperature, the burner is constantly turned on and off.

Classification of gas burners by temperature control

WITH modern development technologies have developed new, improved ways to automatically regulate temperature:

• Single-stage burners are the simplest devices, the operating principle of which was described above. These burners operate in the same mode.

• Two-stage burners are devices that can operate in two states (40% and 100% of total power), switching between themselves automatically.

• Smooth two-stage burners - these also operate in two states (40% and 100%), but the switching between modes occurs more smoothly, which significantly saves fuel itself and improves the quality of temperature support.

• Modulating gas burners with boiler automation are the most functional devices, capable of operating in a wide power range (from 10 to 100%). They can maintain a temperature regime with a deviation of only 20C from initial value. At the same time, the efficiency of fuel combustion increases and the temperature loads on the parts of the heating device decrease.

The most effective among all is the copper heat exchanger, as it has thin walls and good thermal conductivity. BUT it does not tolerate high temperature voltages well, therefore it has a short service life. In combination with a modulated automatic gas burner, its service life increases.

Gas burners with the option to change the combustion level are expensive, but their efficiency quickly pays for all costs:

— the temperature is maintained in a small range;

— fuel savings up to 30%;

— the service life of the entire device is increased.

So we recommend buying a gas burner with automatic control!

Basic elements of an auto control system

Devices included in the burner electrical circuit to start automatic operation of the device:

— Relay is maximum. and minimum gas pressure - has a light structure, which affects its long service life. The principle of operation is that the gas pressure affects the membrane, and when it deviates from the set mode, the system is activated and the control valve carries out the required work. Relay min. gas pressure protects against a decrease in gas pressure to a critical point, and the maximum pressure switch makes adjustments, preventing an increase in the permissible value.

— Minimum and maximum coolant pressure relay — protects the heating system from excessive decrease and increase in pressure of the heating device. Both options are dangerous and undesirable for the continued operation of the boiler, therefore, when the critical point (lower or upper) is reached, the boiler turns off, that is, the gas supply stops.

— The combustion controller is a part that combines the operation of the entire burner into a common process. The operation of gas burners in heating boilers with automation is divided into several sections, which correspond to the required position of the fuel control valve and air damper. Having received a signal about a low temperature, the controller opens the appropriate mechanisms to increase the combustion force. The controller operates based on signals from various sensors (temperature, pressure).

— The thermostat is a signaling device for reaching temperature limits. Based on its signal, the combustion modes are changed.

— Boiler filling sensor — necessary to protect the burner from turning on without the presence of coolant in the boiler.

The connection of sensors largely depends on the boiler manufacturer. This data can be seen in the device passport, and the features of connecting sensors are carefully described in additional instructions. In this case, the connection and configuration of the automatic system must be checked by a gas service employee. In his presence, commissioning work is also carried out, with the obligatory drawing up of a report on the serviceability of the equipment for safe operation.

Types of auto control systems for gas boilers

There are control systems of different brands and purposes, but they all work on the same principles. They differ only in the functionality of the system and dependence on the electrical network.

All varieties can be combined into three main groups of gas burner automation:

1. Non-volatile types.
2. Energy-dependent wire systems.
3. Volatile wireless.

The non-volatile boiler control structure is the most basic automation for a heating device. Its operating principle is based on physical law expansion when the material is heated. A similar effect of this law can be observed in the example of a thermometer - mercury, when heated, expands and rises upward along a tube attached to the scale. The reverse process is visible when cooling.

Now imagine that the same design stands inside the boiler and measures the temperature of the heated device, only instead of mercury they use another material (metal). It expands when heated and affects the mechanical lever that stops the gas supply. As soon as the burner cools down, the metal contracts, acting on the lever, and the gas supply is resumed.

The energy-dependent boiler control system operates from the electrical network - which creates inconvenience, but at the same time increases the productivity of the equipment. The main part of such systems is the thermostat. Depending on the temperature conditions, it supplies an electromagnetic pulse to the gas valve. But with the help of a special program, it is possible to program the temperature regime for several days in advance, weeks or even months.

The non-volatile wireless boiler control system operates on the same principle as a wired one. The only difference is that the control module of the wireless version is located in any place convenient for you, and it is not connected by wire to the device.

Some devices provide for the installation of a GSM module that provides access through mobile gadgets (smartphones, tablets). To find out the latest data on the status of the device, you only need to go to the application on your smartphone and enter the required password.

Through mobile devices it is possible not only to control gas burners with automatic heating boilers, but also to control them. And if a special situation arises, the system will automatically send you a notification in the form of SMS to your number.

Today modern technologies can provide full automatic control over autonomous system heating without creating additional effort.

Selecting a burner correctly is an important step in the construction or repair of a boiler room. The further operation of the heating equipment depends on how responsibly the managers and organizers approached this issue.

Modernization of the heating sector is the most important task facing managers of housing and communal services. Choosing a partner for the design, supply, installation and commissioning of equipment is not a problem, but the question of the efficiency of operation of boiler houses after their conversion remains open. A limited budget forces you to find the simplest solutions - purchase cheap, short-lived equipment that requires constant attention. But now there are fully automated systems, for the selection and maintenance of which it is best to contact highly qualified specialists who have a complete understanding of how a modern boiler room should function.

When choosing burners, consumers are faced with a difficult task: what to give preference to - domestic or foreign equipment. And here sellers of imported burners often use a cunning trick: they compare smooth two-stage burners of foreign production with modulated burners of domestic production. Even with a significant difference in prices for “similar” products, they insist on German, Finnish, Italian quality, trying to persuade buyers to purchase these particular burners. However, any specialist working with boiler equipment understands what to compare different types burners only in terms of the price component is at least incorrect. Therefore, it is necessary to know the difference between them technical characteristics and opportunities.

The most widespread in boiler houses are two-stage, smoothly two-stage and modulating burners. Two-stage burners, as the name suggests, have two power levels. The first stage provides 40% of the power, and the second - 100%. The transition from the first stage to the second occurs depending on the controlled boiler parameter (direct water temperature or steam pressure), the on/off modes depend on the boiler automation.

Smooth two-stage burners allow a smooth transition from one stage to the second. This is a cross between a two-stage and modulating burner. Modulating burners heat the boiler continuously, increasing or decreasing power as needed. The range of combustion mode changes is from 10 to 100% of the rated power.

Of course, modulating burners are more expensive than stepped models, but they have a number of advantages over them. The mechanism for smooth power control allows you to reduce the cycle of turning on and off boilers to a minimum, which significantly reduces mechanical stress on the walls and components of the boiler, and therefore prolongs its “life”. Fuel savings are at least 5%, and with proper tuning you can achieve 15% or more. And finally, installing modulating burners does not require replacing expensive boilers if they are functioning properly. When staged burners operate, the boiler experiences significant loads, which eventually destroy the unit.

Against the background of the disadvantages of stepped burners, the advantages of modulating burners are obvious. The only factor forcing managers to choose step models is their lower price. But savings of this kind are deceptive: wouldn’t it be better to spend a large sum at a time on more advanced, economical and environmentally friendly burners, especially since these costs will pay off in the next few years?

Smart managers understand the benefits of using modulating burners, and now all they have to do is select the necessary models. Which manufacturers are best to contact? Even with a superficial study of prices for imported and domestic burners, it is clear that the difference is quite significant. Some models from foreign manufacturers are more than twice as expensive as Russian-made products. And yet, stereotypes that quality goods come only from abroad force people to pay more. However, a more detailed analysis of the market for burner manufacturers shows that we also have high-quality competitive products. For more than 15 years, the Starorussian Instrument-Making Plant has been producing various models of burners that are successfully installed on all types of domestic and imported boilers. Modulating block burners from this manufacturer comply with all environmental standards for fuel combustion, have a wide range of power control (from 10 to 100%), while ensuring maximum efficiency. When looking for reliable, economical burners for boiler rooms, it’s simply impossible not to pay attention to them. Simple installation of equipment already produces tangible results, and if experienced burner adjustment specialists are involved in the process, fuel savings can amount to more than 15%. With the use of modulating burners from Staroruspribor, managers will be able to temporarily forget about another cost item - replacing the boiler. Switching to a “gentle” operating mode allows you to double its service life. Those who know how expensive such equipment is (prices are calculated in millions of rubles) will appreciate the possibility of replacing these units more rarely.

Selecting a burner correctly is an important step in the construction or renovation of a modernized boiler room. The further operation of the heating equipment depends on how responsibly the customers approach this issue. If, for example, you use modulating burners produced by JSC Staroruspribor Plant, then after two or three heating seasons the costs will more than pay off. Stable operation, compliance with environmental standards, longer service life of boilers and the ability to fully automate the operation of a thermal power plant indicate significant advantages of using modulating burners in boiler houses. And if the benefit from their operation is obvious, not taking advantage of it is simply unreasonable.

Behind effective work boilers are primarily responsible for gas burners for heating boilers.

The design and properties of the burner need to be studied before purchasing the unit: it depends on future expense fuel, the ability to adjust the flame intensity, the level of automation of the boiler operation ().

Operating principle and requirements

In the burner, the burned gas is combined with air. At high temperature is happening chemical reaction with the formation of carbon dioxide and water.

The process occurs with the release of thermal energy. The energy heats up the coolant in the next working unit - the heat exchanger. Combustion products are discharged to the street in one way or another.

What requirements must the burner meet:

• simple design, reliability;
• long service life;
• low noise level;
• ease of switching from one fuel to another (if it is provided for in the boiler design);
• the low emission of nitrogen oxides and carbon monoxide during combustion makes the boiler almost flawless in environmental terms. Of course, the chimney and hood must be arranged correctly.

Classification by air supply method

This method depends on the design of the firebox.

The firebox can be open or closed.

In the first case, air is taken directly from the room, and combustion gases escape through a standard chimney.

The second option assumes that both air intake and smoke exhaust are carried out through coaxial tubes passing through through holes in the wall.

Low temperature burner

In open fireboxes, gas atmospheric burners are used for heating boilers.

The principle of operation is simple: gas enters the wick through an ejector, air is drawn in from the boiler room.

Ignition is carried out by small low-temperature flames. This type can be used in anything from primitive units of an old design to modern advanced models.

In addition to simplicity, low cost and versatility, atmospheric burners have another advantage: low noise level.

Possibility of using ejector burners

If you have enough money to buy a combination boiler, you are in luck: two autonomous fireboxes, you can easily switch from wood to gas and vice versa (). But universal/combination boilers are not a budget option.

Let's say you already have a wood-burning boiler, and you want to convert it into a gas one - more opportunities for automation, fewer problems with the supply of fuel. Gas burners for solid fuel heating boilers are usually atmospheric: the device is simple, there is practically nothing to break.

Do-it-yourself gas burners for heating boilers work on the same principle. To use such a device, it is not necessary to radically alter the entire heating unit.

If, for example, you are converting a wood-burning boiler into a gas one, you can use an ash pan to install the burner, and connect an external automation system for control and adjustment.

It is also recommended to purchase gas burners for old Russian-made heating boilers atmospheric type: the design features of these units do not make it possible to make the fuel chambers completely sealed, and, therefore, quite efficient.

Some solid fuel boilers (for example, pyrolysis models) are already equipped with gas burners for ignition.

Fan burner (pressurized)

In closed fireboxes, free flow of air to the wick is impossible, so they resort to artificial injection. The firebox includes a built-in fan that forces air into the chamber forcibly.

This burner is not as versatile as the previous one, but it has another advantage: it is easier to integrate into a completely automated system boiler control ().

The fan burner multiblock includes the following parts:

• gas filter;
• pressure regulator;
• flow regulator;
• gearbox;
• relay for turning off and forcibly turning on the burner when the pressure drops/increases;
• fan relay (turns off the burner when the fan motor stops).

It is advisable that the system have an uninterruptible power supply in case of a sudden power outage.

The disadvantages of this type of burner are high cost and complexity. Boilers need to be completely rebuilt for them; they are not suitable for all units.

Classification by type of fuel

A gas boiler can operate on natural (main) methane gas or liquefied gas from cylinders (propane-butane). Today the difference in cost is negligible.

Since in suburban conditions it is not always possible to connect to the mains, you will most likely need a propane or butane gas burner for your heating boiler.

Structurally, these boilers are the same; the burners have their own nuances. Burners for natural and liquid gas differ in the design of their nozzles. Many units are equipped with injectors for both types of fuel.

Thanks to this, gas burners for propane heating boilers can be easily reconfigured to work with main gas and vice versa.

Classification by ignition type

Ignition for boilers can be electronic or piezo. Piezo ignition is carried out once, then the igniter is constantly burning, regardless of the gas supply. Electronic – it depends. Triggered when the supply valve opens: the fuel is ignited by an electrostatic spark.

The second option is considered more economical. It also extends the life of the burner. But this method is energy-dependent: with frequent and prolonged power outages, the boiler will be idle.

How to choose a burner

Matter when choosing the following characteristics: range, power and adjustment method. The power should be greater than that of the combustion chamber: this will make it possible to further regulate the operation of the boiler over a wide range.

The adjustment varies according to the number of power levels. There may be one or two stages, as well as modulated adjustment (smooth over the entire range).

Among the brands, German (Buderus, Vaillant), Italian (Lamborghini), and Slovak (Protherm) are in particular demand. Gas burners for Russian production are represented by products from Zhukovsky Machine-Building Plant, Lemarx, Conord.

It should also be noted gas burners for heating boilers Vakula. The company specializes in the manufacture of automatic equipment for burners.

Features of gas burners with automation for heating boilers produced by Vakula:

• piezoelectric ignition;
• coolant temperature adjustment – ​​from 40 to 90?;
• adjusting the gas supply to the fuse;
• gas flow adjustment;
• ability to work at reduced gas pressure;
• automatic shutdown in case of reverse draft or sudden stop of gas supply.

Gas burners for floor heating boilers come in all types: atmospheric and forced, electronic and with piezoelectric ignition.

Which type of ignition is better depends on whether you want to make the system fully automated or prefer manual control and non-volatile equipment.

The choice between an atmospheric and a fan burner is largely determined by power. A floor-standing boiler with an atmospheric burner produces from 10 to 80 kW or more.

The power of a boiler with a forced-air burner reaches several thousand kW. Whether you need to overpay a lot of money for a boiler with such characteristics is up to you to decide.

During the cold season, you want to create comfortable warmth in your home. Apartment owners and country houses People often wonder: what is the most effective way to heat a room? Some use heaters, install autonomous heating, and have heated floors. These devices are used for permanent, temporary or additional heating. They have a simple design, are mobile and relatively inexpensive. During operation, they do not emit combustion decay and are more fuel efficient than electric heaters.

Gas gun design: operating features

A gas gun is a simple device equipped with a burner and a fan. The incoming gas heats the air, and a powerful fan directs warm currents into the room. The device body is made of durable material. The burner is equipped with automatic ignition. Modern models have a thermostat that provides control over the increase in room temperature. This system allows you to save gas and electricity.

Gas guns can run on natural or liquefied gas, depending on the model. In addition to fuel, the device requires electricity, which will power a powerful fan. It is he who carries out the movement of warm air masses in the room.

Features of work:

• Gas is supplied to the burner;
• The fuel ignites due to ignition;
• The air is heated in the metal casing;
• The fan drives a cold stream from outside, drives it through the heat exchanger, and removes heat into the room;
• If the device is equipped with a thermostat, it automatically turns off when the desired temperature is reached.

Operating on liquefied gas and low electricity consumption makes this heating option popular. This is especially true for rooms with difficult access to central heating or constant interruptions in it.

Advantages and disadvantages of a heat gas gun for residential premises

Heat guns are more often used for heating non-residential premises without a stationary coolant: garages, hangars, greenhouses, conservatories. Such a unit is often used in the construction of apartments and houses. It helps to precisely dry the necessary objects: floor screed, plastering, etc.

For residential premises, they prefer to use an electric thermal analogue. Although a gas gun is much cheaper and heats the room much faster. Mandatory approval of the device by the supervisory authorities is the main obstacle to installing a gas gun in apartment buildings.

Advantages of the device:

• Quickly heats the room and removes excess moisture;
• Does not emit toxic waste;
• There is an economical consumption of electricity and gas;
• There are small-sized and mobile devices that are easy to transport and install;
• Not a high price for the device itself, from 4 to 15 thousand;
• Ease of operation.

A gas gun is capable of heating 100 - 150 m2 in a short period of time. For its operation, an uninterrupted connection to electricity and a gas cylinder is required.

How to calculate the power of the unit: gas gun for heating rooms

To calculate the required power, you need to have complete information about the room: know the volume, air temperature and quality of insulation. The temperature must be taken into account both inside the room and outside the building. The quality of insulation consists of several parameters: insulation of the roof, window openings, doors and floors.

According to the standards, these parameters are divided into 4 groups:

• K1 from 0.6 to 1 – good insulation with thick floor insulation, double frames, roof using high-quality insulating material;
• K2 from 1 to 2 – medium insulation with double masonry brick walls, a small number of window openings and standard roof insulation;
• K3 to 3 – satisfactory insulation, single masonry walls, no insulation, simple window frames;
• K4 – lack of insulation, wooden or metal structures.

Next, we make a calculation: we multiply the volume of the room by the insulation coefficient, and multiply the result by the temperature difference between the required and the available one. The resulting total is calculated in kcal/hour. To get the figure in kW, you need to divide the final figure by 860, since 1 kW = 860 kcal/hour.

This calculation works on the condition that the gas gun will be the only source of heating. If complex design premises, you can purchase several devices of lower power. In total they should give the required figure for heating.

Types of devices: gas heat gun

Gas guns can be divided into stationary and portable models. In the first case, a connection to the main gas line is required. The second option is most convenient for construction work, premises where it is sometimes necessary to move or remove the device for some period of time. Portable models run on liquefied propane, which is filled into cylinders. One cylinder is enough for 3 days of continuous operation.

Gas heaters are divided into 2 classes:

• Devices for direct heating of air flow;
• Indirect heating machines.

With direct heating, combustion products enter directly into the heated room. Such units do not have a hose for venting used gases. The burner works by forcing air currents directly onto the flame.

The important point is to provide a sufficient amount of oxygen into the room. This heating method is not permissible in unventilated buildings.

This heater is easy to operate, has a high efficiency and is easy to repair.

Indirect heating guns contain a special element in their design - a separate chamber. The air is heated in it and the combustion products are carried out through the exhaust hose through a special pipe or chimney. The fan blows through the heated chamber, and clean streams warm air heat the room. These models require permanent placement.

Rules for operating a gas heat gun

A gas heat gun is simple and easy to use, but requires compliance with certain safety measures.

How to use the equipment correctly:

• There must be good air ventilation in the room where the device is used;
• Do not block the air duct or dry clothes or shoes on the body;
• Avoid allowing water into the fan and machine body;
• Protect the area of ​​the operating device from flammable objects;
• Carry out daily wet cleaning and avoid high dust concentrations;
• Connect the device to an outlet with the power stated in the operating instructions;
• When replacing a propane cylinder, check the tightness of the connection, eliminating possible gas leakage;
• Install structures above ground level; in the event of a leak, accumulation may occur below, which will create the possibility of an explosion.

Proper use of gas equipment will protect owners and others from unpleasant consequences. To start the gun you need to: screw the reducer with a hose to the gas cylinder, connect the hose to the gun, check it for propane leaks, turn on the device to the power supply, set the required temperature with the thermostat and press the “Start” button. The fan will start working, automatic ignition will turn on, the burner will light up and the room will begin to fill with warmth.

What to look for when choosing a gas heat gun

To decide which gas gun to choose, you need to pay attention to several parameters of the unit. First of all, pay attention to the power and volume of the heated room. The more powerful the device, the greater the fuel and noise consumption. If the unit will be used in residential premises, you need to take into account the noise factor and choose models with its low level. For humans, sound within 40 dB is considered normal for perception.

Next, you should pay attention to the continuity of operation of the device. For constant heating of premises, a device with a long period of operation is required. For portable models, an important factor is the coating of the case. The anti-corrosion surface extends the service life of the heater.

Modern heat guns are equipped with automatic equipment. This allows you to turn off when the device overheats, as well as regulate the heating temperature of the room. Look for models with automatic tip-over shut-off.

Basic parameters when choosing a gun:

• Power;
• Safety;
• Automation;
• Mobility;
• Manufacturer reliability.
