Operating instructions for Daewoo gas boilers + technical specifications and operating instructions

Most homeowners prefer to create an autonomous heating system.

Sometimes such a decision is made even if it is possible to connect to a centralized network.

The reasons for this choice are the desire to independently regulate the heating mode and too high housing and communal services tariffs.

There are a lot of gas heating boilers on sale, which are recognized as the most efficient and economical of all alternative options.

Let's consider gas boilers from Daewoo, which represent one of the most advanced groups of heating equipment.

Repair and operation

If long and high-quality operation of a gas boiler is important to the consumer, it is very important to use only original spare parts and components from trusted suppliers when assembling and further repairing equipment.
It is very important to entrust the initial installation of the boiler to specialists, because they will initially be able to identify all equipment faults, if any. Most often, when installing this type of equipment at home, many clients do not notice technical faults, which later leads to serious financial losses and even complete replacement equipment

It is very important to entrust the initial installation of the boiler to specialists, because they will initially be able to identify all equipment faults, if any. Most often, when installing this type of equipment at home, many clients do not notice technical faults, which subsequently leads to serious financial losses and even complete replacement of the equipment

Repairing a boiler at home is not an easy task, especially if you do not have special skills and experience. Most often, it is recommended to use the services of specialists who have been involved in the installation and repair of this type of gas products for many years.

If you want to carry out the repair yourself, then, first of all, it is very important to study all the instructions for assembling a particular boiler model, its technical characteristics and all the documents that come with this or that model.

For easier operation, it is equally important to know the main error codes that may appear on the gas boiler and control panel. These codes allow you to quickly determine what the problem is with your boiler

These most often include:

“E0” is displayed when the fault is related to the room temperature sensor. Most often, this problem occurs due to a malfunction of the sensor itself or due to broken contacts. To solve the problem yourself, you should check the temperature sensor on the control panel. The main measure to solve the problem is to completely replace the element.

Combination “E1” can be seen when there is a probable loss of pressure in the heating system. Most often this is due to some kind of leak in the system or directly in the boiler itself. To solve this problem, first of all, you have to look for possible leaks, while restoring the pressure.

If “E2” lights up on the boiler, the chimney or air duct is most likely clogged

To fix the problem, it is very important to check the condition of these pipes and channels. If the coolant overheats, the “E3” combination will light up. The problem occurs if there is poor circulation in the coolant

To resolve this type of problem, it is important to check the taps, the condition of the dirt filter and the circulation pump. Only after identifying a breakdown should you look for a suitable replacement part. If the chimney is clogged, then “E4” lights up.

However, as experience in operating these products shows, they are distinguished by increased requirements for the correct conduct of preparatory work and the first start-up of the heating boiler.

Stages of building a warm chicken coop

If we consider the construction of a poultry house, it consists of the following stages:

1. Design is the creation of a detailed drawing of the future structure with all the features of the internal layout.
2. Selecting a suitable location on the site and marking the construction site.
3. Pouring the foundation - it can be a strip or column base.
4. Construction of floors in two stages (rough and finishing with insulation).
5. Construction of walls and partitions.
6. Roof installation.
7. Insulation around the entire perimeter.
8. Installation of frames in window openings and doors.
9. Making perches and nests for chickens.
10. Creation of a high-quality ventilation system.
11. Heating installation or installation of heating devices.

With the right approach, building an insulated chicken coop with your own hands for ten birds, even a beginner will not have problems with the construction of the structure. Only under comfortable conditions will laying hens delight their owner with delicious, healthy eggs every day.

Device and technical characteristics

The Korean company is ready to offer the buyer two main models of gas equipment: atmospheric and turbocharged.

Regardless of the internal solution, there are still general technical parameters that characterize all equipment of the Daewoo brand:

1. Burner ignition control. The mode is selected depending on the gas pressure in the line, the condition of the smoke removal system, as well as the presence of draft and mains voltage. The flame is regulated by a control panel or using a mechanical regulator.
2. Remote control. The operation of boiler equipment can be controlled from any room using the following methods: a remote panel or a remote control.
3. Circulation pump device. The boiler's technical characteristics, simplicity and high efficiency contributed to the replacement of the traditional three-way valve. The developers of the Daewoo have introduced a two-way pump with a “ball-switch” system. Large capacity of the hot water supply circuit - warm water warms up evenly. The simultaneous number of users, as well as the pressure in the water supply system, does not affect the heating degree.
4. Automatic boiler diagnostics. Test data is displayed on the remote control unit of the unit, which has a digital display.

The Daewoo Gasboiler double-circuit turbocharged wall-mounted gas boiler has high efficiency and cost-effectiveness. The closed combustion chamber allows installation of equipment even in small rooms that have not been converted into a boiler room.

Installation and connection basics

Although installing the Daewoo Gasboiler boiler is not difficult in itself, self-installation has several disadvantages.

• As practice shows, problems with Daewoo boilers are primarily related to mistakes made during installation.

Representatives of the company selling heating equipment have the right to refuse warranty service. An employee with the appropriate license must set up the boiler and perform its first startup.

Piping the boiler may involve connecting to the electrical network and installing thermostats in the apartment. This will require permission to work with electrical equipment and an understanding of the rules of the Electrical Regulations.

Download: Daewoo Altoen – installation, operation and maintenance instructions.pdf

The basic installation rule remains the need to strictly adhere to the manufacturer’s recommendations regarding the installation of equipment. The operating instructions provide a schematic diagram of the piping and requirements.

Which boiler to choose - turbocharged or atmospheric

For an apartment, it is better to choose a turbocharged model. It connects to a coaxial chimney. PPB rules and requirements for the installation of turbocharged gas equipment are lower than for atmospheric equipment.

The disadvantage of turbocharged boilers is their dependence on electricity. Atmospheric models are non-volatile and continue to work even when there is no voltage in the network.

Atmospheric and turbocharged boilers from Daewoo are easy-to-use and reliable models, attractive for their cost and useful functions. A good alternative to European equipment in the mid-price category.

Gas boilers from Daewoo

The Korean industrial giant Daewoo is known throughout the world primarily for its cars. However, the product range is much wider and includes many different positions and directions.

The company name Daewoo is translated into Russian as “Great Universe”. It was founded in 1967, and the first gas boiler left the assembly shop in 1988. Today the company is a corporation of global importance, which includes many branches and related companies.

Active research and development is underway, resulting in the emergence of new designs, components and parts.

For example, the electronic ignition system was first implemented on Daewoo gas boilers.

The range of heating boilers produced by the company is quite wide. All the most promising designs are produced that can ensure stable and trouble-free operation for a long time.

The company's goal is to produce relatively inexpensive, but very reliable units. This is achieved by excluding minor or low-demand components that increase the price of equipment without bringing noticeable benefits.

In addition, more efficient and inexpensive models of important components have been developed - for example, a new type of three-way valve that is more reliable and easier to manufacture.

A feature of Daewoo boilers is their relatively low power, designed for use in small private homes. This approach demonstrates a focus on the mass consumer, and it produces positive results.

For example, it was possible to reduce fuel consumption by 7-10% by reducing the number of gas burner sections.

The Daewoo company produces the most popular and convenient wall-mounted gas boilers for use in a private home.

There are no floor-standing models in the company’s arsenal, which is not a drawback, but demonstrates the approach of the company’s engineers to creating the most compact and multifunctional models.

According to the type of combustion chamber, two options are available:

• Atmospheric boilers. The combustion chamber is open type, and the air required for combustion and smoke removal is taken directly from the room in which the boiler is installed. They are connected to a common house chimney and require the creation of certain conditions for operation. DO NOT tolerate drafts or sharp gusts of wind outside - the flame may go out.
• Turbocharged boilers. The air supply occurs under the action of a turbocharging fan. This design makes the boiler completely independent of external factors, and the operating mode is stable and sustainable. Connecting the boiler to a common chimney is not required; special chimneys of the coaxial type (“pipe in pipe”) of the horizontal type are used, which can be led directly out of the room through the wall. Forced air units are stable and in higher demand.

By type of heat transfer there are:

• Convection boilers. They work on the usual principle - heating the coolant in a burner flame.
• Condensation models. A new type of design that uses two-stage heating of the coolant. First, the thermal energy obtained by condensing water vapor from the exhaust smoke is used. Then the coolant, which has received some heating, is sent to the primary heat exchanger, where it is finally heated to a given temperature.

The use of condensing boilers began recently, but statistics have already been collected. They provide significant fuel savings due to the recycling of thermal energy.

It becomes possible to reduce the heating intensity of the heat exchanger, which saves gas and increases the service life of boiler components that are not subject to too much load.

Adjusting a gas boiler: recommendations for setting up the device for correct operation

From the article you will understand the principles of adjusting pressure, thrust and power during operation of the device. Find out the probable causes of problems along with options for eliminating them. If you need to tune the boiler, use our materials. Do not forget about the safety rules, and you will successfully configure the device and fix minor problems.

You should be interested in the settings of a gas boiler long before purchasing, taking into account your needs and various features. We have written which parameters can or should be changed in the device you are using. The new device should be configured and prepared for operation, and some undesirable aspects can be corrected.

Operation and setup

Boilers are adjusted during manufacturing, in the factory. Additional setup is a small adjustment made during installation and first run.

The operating limits of temperature and pressure of gas and working fluids are determined. These actions must be performed by specialists from the warranty workshop, otherwise the warranty agreement will be void.

After the first launch, no special actions are required from the owner. Adjusting the temperature to your liking is done as a matter of routine.

It is necessary to invite a specialist once a year to carry out maintenance.

If problems occur, you should immediately invite a technician from the service center.

OPERATION OF THE BOILER

5.1. While on duty, boiler room personnel must monitor the serviceability of the boiler (boilers) and all boiler room equipment and strictly adhere to the established operating mode of the boiler. Malfunctions detected during equipment operation must be recorded in a shift log. Personnel must take corrective action. If it is impossible to eliminate the malfunctions on your own, then you must inform the boiler room manager or the person responsible for the gas supply of the boiler room.

5.2

Particular attention should be paid to:

• To maintain a normal water level in the boiler and uniform supply of water to it. In this case, the water level must not be allowed to fall below the established value, and replenishment is strictly prohibited.
• To maintain normal steam pressure according to the pressure gauge (6-8 kg/cm2).
• For the operation of gas burners, maintaining normal gas and air parameters, according to the regime map.
• Maintain the temperature of the fuel oil within 80-100 o C.

5.3. Checking the serviceability of the pressure gauge using three-way valves, checking the serviceability of the safety valve by forced opening, and purging the lower points must be carried out by the operator every shift and recorded in the logbook.

5.4. When working on gas fuel, to increase the load, you should constantly increase the gas supply first, then air, and adjust the draft. To reduce it, first reduce the air supply, then the gas supply, and then adjust the vacuum.

5.5. If all or part of the burners go out while the boiler is operating, you should immediately shut off the gas supply to the burners, ventilate the firebox and burners, and open the purge plug. Find out and eliminate the cause of the violation of the combustion mode and begin kindling according to the established scheme.

5.6. While the boiler is operating, it is prohibited to tap seams or weld boiler elements.

5.7. All devices and devices for automatic control and safety of the boiler must be maintained in good condition and regularly checked within the established time frame by the administration.

Boiler design and main control devices

The copper heat exchanger has a long service life.
The design features of the Daewoo boiler are not particularly difficult. The boiler has the following main elements:

• the combustion chamber;
• double-circuit heat exchanger;
• circulation pump - one or two;
• measuring instruments - pressure gauge, thermometer, thermostat.

The devices are produced in the form of boilers. When heated, the water circulates inside the device, and the entire system operates. Wall-mounted models take up a small area, are convenient and allow owners to heat the room using a compact model.

The boiler has a built-in control unit. Using a backlit digital console, you can see all the information about the operation of the equipment and control the process. The operation of the device is also programmed using an electronic daily timer.

Device and technical characteristics

Daewoo offers consumers two main modifications of gas boilers: atmospheric and turbocharged. Each device has its own distinctive features, advantages and disadvantages.

Regardless of the internal structure, there are general technical characteristics characteristic of all South Korean heating equipment of the Daewoo brand:

• The burner is ignited in a controlled manner. The choice of operating mode is determined by the gas pressure in the main, the state of the smoke removal system, the presence of draft and voltage in the network. Flame adjustment is carried out from the control panel or using a mechanical regulator.

Equipment with remote control. The operation of the boiler can be controlled from any room in the room in two ways: with a remote panel or with a remote control.

Circulation pump device. The technical characteristics of the device, the simplicity and efficiency of the design made it possible to replace the traditional three-way valve. Daewoo has developed and implemented a two-way pump with a “ball-switch” system. Large DHW throughput - hot water is heated evenly. The temperature does not depend on the simultaneous number of consumers and pressure in the water supply system.

Boiler diagnostics are carried out automatically. The test results are displayed on a remote boiler control unit with a digital display.

One of the advantages of Daewoo heating boilers is their simplicity of design. According to reviews from craftsmen, equipment can be disassembled, repaired and adjusted practically with “one screwdriver.”

Advantages and disadvantages

The advantages of boilers include:

• High efficiency of units.
• Reliability, durability of boilers.
• Resistance to external influences.
• The ability to independently identify problems and notify the owner about them.
• Together with space heating, hot water is supplied.
• Low fuel consumption, which does not affect the performance of the units.

The disadvantages of Daewoo boilers are considered to be:

• Energy dependence. If there is a power failure, the system will stop operating.
• Sensitivity to water quality, stable supply voltage, requiring the use of additional equipment.
• Some users report increased noise levels when heating water.

Most of the disadvantages can be attributed to the general features of gas boilers.

Heating boiler error codes

Daewoo gas boilers are rightly recognized by users as highly reliable and ready for use in Russian municipal conditions.

In order for the service life to be as long as possible, the owner will be required to strictly follow production instructions and routine maintenance. Maintenance work should be carried out in the summer, long before the start of the heating season, so that there is enough time to correct any identified faults.

Maintenance instructions

Once again, the user will be required to carefully configure automatic functions. For example, most Korean gas boilers support options for air removal, tank disinfection, fault detection, etc.

As for physical maintenance, it is important to prepare for some repair operations, which a Daewoo gas boiler can undergo at home. Spare parts are supplied separately - a typical list of main components includes heat exchangers, expansion tanks, fans, pipes, pipes and accessories for loop infrastructure

It is important to note that regular maintenance can significantly increase the cost of maintaining equipment. This depends on the gas consumed and on the use of new consumables with components

For example, a gas boiler, the price of which is no more than 20 thousand, on average every six months requires an investment of up to 2-3 thousand to update pipes and fittings.

Price range

The cost of Daewoo gas boilers is in the conventional range of 34-59 thousand rubles. The price difference depends on the model, power and other factors.

If the region is located far from large populated areas, the price of the boiler will increase due to logistics costs. Before purchasing, you should find out in what configuration the equipment is supplied and what needs to be purchased in addition for optimal and safe operation of the boiler.

In addition, you need to take care of concluding a warranty agreement, which will also cost a certain amount.

IMPORTANT!

Some users do without warranty service, but this approach is only possible for specialists who can independently repair and configure the boiler. For mass users, it is strongly recommended to use the services of warranty workshops.

Wolf gas boilers

Wolf GmbH was founded in 1963. During its activity, the company managed to grow into a large industrial concern engaged in the production of heating, climate control and water heating equipment.

Gas boilers occupy a prominent, although not the main place in the list of company products. A special feature of the equipment is the absence of scattered production and assembly across different countries, which is typical of other well-known European brands.

Despite the fairly widespread use of imported custom parts, the units are assembled in Germany, which ensures quality and compliance with all requirements and standards. The boilers are adapted to the technological conditions of the countries in which they will be used.

This helps to overcome a lot of problems, for example, according to manufacturers, the boiler electronics are able to compensate for voltage drops of up to 160 V.

The operational capabilities and reliability of Wolf boilers were highly appreciated by specialists and ordinary users, and were also awarded the corresponding diplomas and certificates.

Daewoo gas boiler series

Daewoo is one of the most famous Korean conglomerates, which ceased to exist in 1999. Many divisions of the concern gained independence or merged into the structure of other companies.

Now in South Korea there are two companies that were previously related to the corporation and produce gas boilers:

• Altoen Daewoo Co., Ltd (until 2022 - Daewoo Gasboiler Co., Ltd). Now production facilities are located in Dongtan.
• Daewoo Electronics Co., which produces gas equipment at the factories of the KD Navien company.

Components for boilers from both companies are manufactured in South Korea and Japan, and assembly is carried out automatically.

Altoen Daewoo Co., Ltd did not transfer production facilities to Chinese industrial clusters so as not to lose the opportunity to constantly monitor the quality of products

The following lines of gas boilers from Altoen Daewoo Co. are presented in Russia. Ltd:

• DGB MCF. Boilers with an open combustion chamber.
• DGB MSC. Boilers with a closed combustion chamber.
• DGB MES. Condensing type boilers with a closed combustion chamber. Models in this line have a weekly operation programmer, an autonomous control panel, and simplified chimney connection.

All models of the listed lines are wall-mounted, double-circuit, that is, designed for heating and hot water supply.

Models of the DGB series are equipped with an informative display that displays an error code if a problem occurs or the built-in automatic diagnostic system is triggered

Daewoo Electronics Co. There are two lines of gas boilers: wall-mounted “DWB” and floor-mounted “KDB”. They have their own characteristics, including error codes that differ from competitor models. However, these boilers are not widely used in Russia.

Therefore, this article will only provide error codes for gas boilers from Altoen Daewoo Co., Ltd.

Daewoo MSC series

Daewoo MSC boilers are double-circuit devices with a closed chamber, the rated power of which, depending on the modification, can range from 7 to 46.5 kW. This line of units is represented by 8 different models.

This technique has some peculiarities. In particular, its main heat exchanger is made of copper, which provides the equipment with a long service life. In turn, the hot water heat exchanger has a plate shape, which ensures rapid heating of the coolant. The burner installed in Daewoo MSC boilers is made of stainless steel. In this case, the unit is equipped with all the necessary automation and security systems. You can control the operation of the boiler using a remote control with an LCD display.

The device has several modes that make it easier to control its operation. Among them:

• "Heating";
• "DHW";
• “Heating + DHW”;
• "Minimum heating";
• "Accelerated DHW"
• And so on.

The coaxial chimney provided by the design of the MSC unit prevents the burner flame from blowing out in the event of sudden gusts of wind outside the window. It is possible to install separate chimneys, which is important when heating several apartments. The factory design of the MSC boiler is designed to operate on natural gas, but the nozzles can be changed at any time, and the unit will be able to operate on liquefied fuel.

conclusions

Daewoo boilers today are represented by a large selection of heating systems offered on the domestic market for relatively little money. If you are looking for reliable and at the same time innovative equipment, but are not ready to overpay for European units, then the equipment of the South Korean brand is ideal for you.

How to properly set up a daewoo gasboiler 100 boiler?

Which mode is the most effective for an apartment in winter? From the air temperature or from the temperature in the pipes?

How to properly heat a solid fuel boiler?

You can melt equipment that runs on solid fuel in two different ways: burning and layers. Each option allows you to increase the burning time of one load. Firewood is placed in the firebox. For faster ignition, you need to add paper or wood chips. After the flame appears, the loading door closes and the heater control unit turns on.

The process then proceeds as follows. Firewood, coal or briquettes burn from top to bottom, giving off the maximum possible amount of heat. Combustion in a firebox in this way can continue for a long time.

After switching on, the unit must be brought to optimal operating mode by setting a deliberately high heating temperature. After the equipment reaches the optimal temperature regime, you can reduce the boiler power by setting the necessary temperature parameters.

For some models, one download is enough for 24 hours (in standby mode up to 48 hours).

Combination boiler

Combined installation
In places where the gas supply may be temporarily interrupted or in the presence, for example, of a solid fuel heating boiler, a combined heating installation shows good results. It consists of two circuits:

• a direct heating gas boiler, the task of which is to ensure the temperature of the water during its intensive selection;
• an indirect heating boiler, the heat source of which is the liquid supplied by the main heating boiler or the exhaust gases generated during its operation.

Combined heating systems show significant cost savings. It is rational to use them if there is a sufficient supply of boiler power in the heating system. With a significant capacity, they are able to meet the hot water needs of a large family even without starting a direct heating circuit. Also, if the gas supply is interrupted, the combined boiler will perform its functions using the energy of the heating system.

Review of the best models

The most popular model from the line of this brand among Russian buyers is the Daewoo DGB 100 MCF boiler.

Main technical characteristics:

1. Operating power is 10 kW, enough to heat an individual residential building with an area of ​​up to 100 m2.
2. A closed combustion chamber with a turbine flue gas removal system prevents carbon monoxide from escaping into the boiler room.
3. Ignition of the boiler with an electronic igniter, which not only starts the Daewoo boiler into operation, but also controls the quality of the combustion process during operation. Electronic burner control takes part in the automation and safety control system, as well as adjusting the operation of the boiler depending on the outside air temperature and the set coolant parameters.
4. To increase the durability of boiler equipment, the pipe system of heat exchangers of Daewoo boilers is made of copper.
5. The network circuit is equipped with a built-in forced circulation system, which allows you to work with low gas pressure in the main line or low pressure of tap water.

Operating principle of the Daewoo DGB 200 MCF condensing boiler:

1. Electronic ignition of the gas injector.
2. When gas is burned, its hydrogen content turns into water vapor. The condensing device of the boiler is capable of turning the generated steam into liquid, while extracting additional heat and increasing the efficiency of the steam power cycle.
3. The infrared sensor of the unit controls the combustion process in the furnace, establishing optimal combustion conditions in the fuel-air ratio based on the color of the flame, which leads to significant gas savings. The system operates on two types of fuel: natural and liquefied gas.
4. Water is supplied by a circulation pump to two heating circuits: heating and domestic hot water, where it is heated and supplied to consumers.
5. The control panel controls the operating mode of the boiler unit. The shut-off valve turns off the gas supply to the heating boilers; when emergency values ​​for the temperature and pressure of the coolant are reached, the process is accompanied by an audible alarm, while the operating parameters are preserved.
6. The diagnostic system will display an error code on the screen so that maintenance personnel can take measures to eliminate the operating failure.
