A little about production

Danko gas boilers are almost entirely produced using imported equipment - it is supplied from Japan, Finland, Denmark and other countries. This allowed us to improve the quality of our products and make them more reliable and durable. The production involves modern assembly and metalworking machines, powder coating equipment, cutting equipment and much more. Most operations are automated, but some are performed manually.

Danko boilers are presented in two categories:

• Floor-standing models – a wide range of equipment with power from 8 to 96 kW;
• Parapet (wall-mounted) models - wall-mounted models with closed combustion chambers with a power of 7 to 15 kW.

The manufacturer also produces additional equipment - these are thermostats, programmers, kits for converting Danko boilers to liquefied gas and water converters.

The lineup

The line is represented by five series:

• Wall-mounted. Two modifications - 23 ZKE and 23 VKE. Double-circuit modifications. Each circuit has its own heat exchanger. For heating - copper, for hot water supply - steel.
• Parapet. 8 modifications - 7, 10, 12.5 and 15.5 kW. They are compact. Single-circuit. No smoke. Can be installed in apartments with an area of ​​140 square meters. Heat exchanger – steel.
• Steel. 22 models differ in power, number of circuits and location of chimneys.
• Cast iron. All have an open chamber. Cast iron radiators last approximately 25 years.
• With pump. 4 modifications. They work to heat the room and heat hot water. Steel heat exchangers. Related security systems.

Boiler design using the example of Danko 10/12

The model has a built-in water heater - it can be used to heat a private home and heat hot water. Appearance: rectangular cabinet. The facade is equipped with a door that closes and provides access to the elements responsible for ignition. Comprises:

• burners;
• heat exchanger;
• gas automation;
• decorative casing.

The automatic unit is responsible for supplying fuel to the burners - main and ignition, and for regulating the water temperature. Gas flow stops immediately if:

• the flame went out;
• the gas pressure has dropped below the permissible value;
• there is no draft in the chimney;
• The coolant temperature reached 90 °C.

Double-circuit modifications consist of structural elements:

• chimney duct;
• blower fan;
• gas burner;
• heat exchangers – primary and secondary;
• hydraulic unit;
• connecting fittings;
• pump for forced water circulation;
• expansion tank;
• an automation unit that controls the units of the device.

A distinctive feature is that all components are produced by European companies. This is a plus in favor of the reliability and cost-effectiveness of Danko brand products.

Possible problems with the boiler

Frequent questions from users regarding malfunctions of this Ukrainian equipment include the following:

1. Why does the Danko gas boiler blow out?
2. Why does the unit go out?
3. What causes high gas consumption?

If we summarize the practical experience of the owners and take into account the opinions of experts, we can make a small list of possible causes of these problems:

1. Gas line failures (gas is supplied unevenly).
2. Problems with the chimney (most likely, soot and soot have accumulated on the inner walls, which impede the proper removal of combustion products).
3. Possible damage to any structural elements. For example, a malfunction of the ventilation device, which does not supply air flow to the combustion chamber.
4. Electrical supply problems that directly affect the operation of boiler equipment. In other words, interruptions in the functioning of the circulation pump or blower fan, which affects poor heating of the room.
5. There is no valve in the smoke structure, this does not allow the reverse draft to work normally, as a result - the system blows out and attenuates.

Experts recommend thoroughly cleaning the chimney of deposits.

How to light a Danko gas boiler?

Light the boiler using a semi-automatic method in stages:

1. The mechanical regulator is brought to its extreme position.
2. Press the wheel down for 5-6 seconds. Gas is supplied to the burner.
3. Ignition occurs using a piezoelectric element.
4. After igniting the ignition burner device, continue to hold the regulator in the down position for approximately 5-10 seconds. If, after lowering the wheel, the igniter goes out, the procedure begins again. The burner has a sensor that records the temperature on the body. If the burner device is not heated sufficiently, the gas supply valve is not opened.

Additional systems

In the design of gas heaters, the manufacturer has additionally provided:

• water temperature sensors - triggered when boiling, turning off the system;
• a protective block that shuts off the gas supply when the wick goes out;
• a block that stops equipment operation in the absence of traction;
• draft control unit - to adjust the flame;
• multifaceted protection unit – turns off the device in case of any type of threat;
• intelligent block - for distributing liquid flows.

User manual

The boiler operates automatically. The user is only required to maintain the cleanliness of the body, fill and drain water from the system and start the boiler when necessary.

Temperature adjustment is carried out in operating mode, according to the user’s own feelings. The boiler is started either using a piezo ignition system or manually using the principle of a gas stove. To turn on the boiler using piezo ignition, you need to turn the knob to the ignition position.

The thermostat knob must be turned until it aligns with the “asterisk” icon and at the same time pressed in all the way.

Press the piezo ignition button several times to light the burner, but hold the thermostat knob for another 10-15 seconds . If the attempt is unsuccessful, repeat the procedure.

To service and repair the boiler, you should call a technician from the service center. Independent tampering with the structure will automatically void the warranty agreement.

Installation

It is necessary to take into account the rules for installing gas equipment:

• The power is selected according to the heating.
• There must be at least 25 cm between the housing installed on a fire-resistant horizontal platform and a non-combustible wall.
• The device can be installed near fire-resistant walls if they are sheathed with steel sheets.
• The width of the passage in front of the facade is from 1 m.
• To improve water circulation, the installation should be lower than the level of heating devices.
• The expansion tank is located at the very top of the system.
• The minimum length of the chimney is 5 m.
• If the chimney is located outside, it must be insulated.
• The diameter of the smoke outlet must exceed the diameter of the smoke outlet pipe.
• At the junction of the boiler and the chimney, it is necessary to seal it with a solution of cement or clay.

Boiler installation

Installation of Danko gas boilers and connection to the gas main is quite easy. For comfortable operation, the housing includes left and right connections. When installing, it is very important to follow the following expert advice:

1. The gas supply is regulated manually using automation. To increase the power of the unit, set the required mode using a rotating wheel.
2. The Danko wall-mounted gas boiler is mounted using anchor bolts. During operation, the maximum weight of the device is 80-100 kg. It turns out that the fasteners must be very reliable to withstand such a load. With proper installation of the boiler, possible excessive fuel consumption and other problems can be eliminated.
3. To minimize gas consumption, an external temperature sensor can be used. The operation of the device is to determine the ambient temperature, as well as auto-adjust the specified mode of the boiler equipment. The temperature sensor works in this way: it records the ambient temperature and transmits information to the controller. Automation detects changes and introduces them into the specified temperature regime. As a result, gas consumption becomes lower.
4. Chimney – can be connected to a classic and coaxial smoke exhaust system.

Fire safety requirements for the installation of parapet devices are not as high as for atmospheric models. Therefore, in apartments it is recommended to install models with a closed combustion chamber.

The article described all the distinctive features of the brand’s heating devices, the installation of boilers, and examined their possible operating problems: why a Danko gas boiler goes out, goes out and takes up a lot of fuel. Take note of the recommendations of experts, reviews of owners, and the heating unit will serve you for a long time.

Operation and Maintenance

Commissioning is possible after acceptance by representatives of the gas service. An installation diagram is attached to the instructions. Installation is quite simple, but it is better to trust it to specialists. Gas workers who take the device into operation provide appropriate instructions. The modification is selected according to the project completed by the gas service, which necessarily notes the power of the device and its type. Safety regulations:

• Maintenance of the device can be performed by those who have attended the instructions.
• In the event of a breakdown, immediately turn off the taps.
• If you smell gas, turn off the valve, open the windows and call the gas workers.
• Keep the device clean and in good working order.
• Clean the chimney as often as indicated in the instructions.
• Check the fullness of the system weekly to see if there is water in the expansion tank.
• At the end of the service life of the device provided by the manufacturer, invite a specialist for advice on whether it can continue to be used.

How to light a Danko gas boiler

Identification of boiler control elements.

1. Turn the mechanical temperature regulator counterclockwise until it stops.
2. Make sure that the tap on the gas pipeline inlet is open.
3. Press and hold the start button, then press and release the piezo button (several clicks may be required, repeat until the pilot burner lights up). Hold the start button for at least 30 seconds until the burner goes out when it is released. If the boiler has not been adjusted previously, it may be necessary to adjust the air supply by turning the nut on the ignition burner until the burner flame turns blue.
4. Turn the thermostat knob clockwise until the main burner turns on, then set the desired power.

The startup process differs slightly for configurations with different automation; the algorithm is described in detail in the operating instructions, an electronic copy of which is attached in the description of each model on the official website.

What problems happen?

The simplicity of Danko's design allows its owners to carry out minor repair work on their own. One of the most common problems is the burner blowing out. This is especially common in strong winds. Usually no fault is found, the wind is the culprit of the problem, but it is better to check the following points:

• Is there a check valve installed in the chimney? If not, then there will be no reverse thrust, which is why attenuation occurs.
• If the chimney is installed incorrectly, it becomes clogged with soot and other combustion products - it needs to be cleaned.

It happens that before the attenuation, extraneous noise is heard or increased fuel consumption is observed - this may indicate a failure of the controller. The task is to repair or replace a spare part.

Important! If you don’t want to deal with flame extinction, choose not a single-circuit, but a double-circuit boiler - wall-mounted or floor-standing. 2-circuit models do not have such disadvantages.

Another common problem is the pilot light going out. It goes out due to the activation of the thermostat, which shuts off the gas supply if the burner does not heat up to the desired temperature.
