The device of the boiler on the example of Danko 10/12
The model has a built-in water heater - it can be used for heating a private house and heating hot water. Appearance - a rectangular cabinet. The facade is equipped with a door that closes and opens access to the elements responsible for ignition. Consists of:
- burners;
- heat exchanger;
- gas automation;
- decorative casing.
The automatic unit is responsible for supplying fuel to the burners - the main and igniting ones, and for adjusting the water temperature. Gas flow stops immediately if:
- the flame went out;
- gas pressure has dropped below the permissible value;
- there is no draft in the chimney;
- coolant temperature reached 90 ° C.
Double-circuit modifications consist of structural elements:
- chimney channel;
- blower fan;
- gas burner;
- heat exchangers - primary and secondary;
- hydraulic unit;
- connecting fittings;
- pump for forced circulation of water;
- expansion tank;
- automation unit that controls the nodes of the apparatus.
A distinctive feature - all components are produced by European companies. This is a plus in favor of the reliability and cost-effectiveness of Danko brand products.
Additional systems
In the device of gas heaters, the manufacturer additionally provided:
- water temperature sensors - trigger when boiling, turning off the system;
- a protective block that shuts off the gas supply when the wick attenuates;
- a unit that stops the equipment in the absence of traction;
- traction control unit - for setting the flame;
- multifaceted protection unit - disconnects the device for any type of threat;
- intelligent unit - for the distribution of fluid flows.
Installation
It is necessary to take into account the rules for installing gas equipment:
- Power is selected according to heating.
- There must be at least 25 cm between the body mounted on a horizontal refractory site and a non-combustible wall.
- Near difficult-to-burn walls, the apparatus can be installed if sheathed with steel sheet.
- The width of the passage in front of the facade is from 1 m.
- To improve water circulation, installation should be carried out lower than the level of heating appliances.
- The expansion tank is located at the very top of the system.
- The minimum length of the chimney is 5 m.
- Having the chimney outside, it is necessary to insulate it.
- The diameter of the chimney must exceed the diameter of the chimney.
- At the junction of the boiler and the chimney, it is necessary to perform a seal - with a solution of cement or clay.
Operation and maintenance
Commissioning is possible after acceptance by representatives of the gas service. The 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, conduct the appropriate briefing. The modification is selected according to the project carried out by the gas service, which necessarily indicates the power of the device and its type. Safety regulations:
- Maintenance of the device can be performed by those who have listened to instruction.
- In case of breakage, immediately turn off the taps.
- If there is a smell of gas, close the valve, open the windows and call the gas men.
- Keep your device clean and healthy.
- 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 be used further.
What are the problems?
The simplicity of the design of Danko allows its owners to carry out small repairs on their own. One of the most common problems is blowing out the burner. Especially often this is encountered in strong winds. Usually there is no malfunction, the wind is the culprit of the problem, but it is better to check the following points:
- Is a check valve installed in the chimney? If not, there will be no reverse thrust, which is why attenuation occurs.
- If the chimney is not installed correctly, it is clogged with soot and other combustion products - you need to clean it.
It happens that before attenuation an extraneous noise is heard or an increased fuel consumption is observed - this may indicate a controller failure. The task is to repair or change the spare part.
Important! If you do not want to face flame attenuation, choose not a single-circuit, but a double-circuit boiler - wall or floor. 2 circuit models do not have such drawbacks.
Another common problem is the fading of the igniter. It goes out due to the operation of the thermostat, which shuts off the gas supply, if the burner does not heat up to the desired temperature.
How to ignite?
Semi-automatic ignition method:
- Put the control knob in the extreme position.
- Press in the wheel by applying gas and performing piezo ignition.
- Press the wheel for another 10 seconds. If the fire goes out after it is released, repeat the steps.

Reviews
Danko 8 C: Grigory I., Magnitogorsk
I remembered the first ignition - it was hard. The piezoelectric element gave a spark, but the wick was ignited after 5-6 attempts. The burner did not ignite for a long time. The flame finally appeared, but with some strange sound. Further work went fine - a stable flame, even burning. Plus - quick warm-up of the system. After practicing the season, I can name the advantages - profitability. With an old boiler, I spent 500 cubic meters per month, now - 300. It works without failures. You can adjust the temperature smoothly - 1 degree. Stable temperature. Cons - starting from a cold state. It is necessary to click several times until the wick lights up.
Danko 20: Victor B., Lgov
I have a 2-loop device has been working for 3 years. The hot water that he warms is not enough even for washing dishes. It’s worth the Minisit automation, due to which some troubles constantly happen - the ignitor goes out, turns off completely. It is impossible to turn on the igniter normally - it does not light up. The flame from the middle burner can go outside, and with a little wind it completely goes out. It consumes up to 30 cubic meters. in severe frost - and they also say that it is economical. One tear.
Ukrainian Danko boilers are a good alternative to expensive European models. Featuring durability and simplicity of design, they have gained a reputation for reliable equipment adapted to domestic conditions. Among the wide range, represented by boilers of different capacities, each consumer can choose an option that meets the needs.
