Single-circuit gas boiler Conord AOGV-11.6-1 SIT with a connection similar to AOGV Rostovgazaparat

About company

The production facilities of the Russian brand Conord are located in Rostov-on-Don. Gas heaters have been produced here since the seventies of the twentieth century. Today it is a leading Russian manufacturer, the quality of its products is based on large-scale modernization of production. Instead of old machines, European lines were launched - Swiss and Italian. The cost of manufactured heaters is much lower than European ones - in the range of 15-50,000 rubles.

CONORD is not just a name consonant with the name of a large eagle, it is an abbreviation. It stands for: Heating boilers of non-standardized equipment Rostov-on-Don. The first heating boiler produced by the company is DON-16.

Advantages

After reading reviews about the products of the Rostov enterprise, it is easy to understand that they are in high demand. The Russian consumer is attracted to Conrod products by:

• Cost - prices for Russian products are much lower than for European ones. Sometimes the difference is 50%. The cheapest 8 kW models, used for heating a private home, cost only 15,000 rubles.
• Long warranty. The manufacturer guarantees uninterrupted operation for fifteen years.
• Does not depend on electricity. A blackout, especially in winter, due to lack of electricity, is almost a disaster. Therefore, for volatile equipment it is necessary to install backup power - a generator or battery. There are no such problems with Conord.
• Easy to use. The abundance of functions, electronics and automation from other brands often causes unnecessary trouble.
• Quiet operation.
• High quality build.
• Good technical characteristics: Rostov boilers are practically not inferior to foreign analogues in productivity, efficiency, and heating speed.

What are they?

If you are interested in the products of the Rostov manufacturer, you can choose a boiler from four series.

• With Italian automatic equipment SIT: KSts-G-S/ KSts-GV-S - single-circuit/double-circuit.
• With thermo-hydraulic automation: KSts-G-N/KSts-GV-N - single-circuit/double-circuit.

The manufacturer offers heating boilers with two types of heat exchangers: steel and cast iron. All gas heaters produced by the Rostov enterprise are only floor-standing. If you're interested in a wall-mounted unit (with a closed firebox), you'll have to look to a different brand.

Steel

Heaters with steel heat exchangers have the following advantages:

• Steel is more ductile compared to cast iron.
• Specific gravity is less.
• High heat dissipation.

There is one minus, but a very important one - low resistance to damage and corrosion. That is why consumers who know a lot about materials choose cast iron analogues. Manufacturers try to minimize this by using durable coatings, but they cannot provide 100% corrosion protection.

Cast iron

The main advantages of cast iron heat exchangers: high thermal conductivity and immunity to corrosion.

Minuses:

• Cast iron is less flexible and ductile than steel and is not as resistant to deformation.
• Inferior to steel in strength.
• Brittleness is the main disadvantage of cast iron. Particularly dangerous situations arise during transportation and installation, which is why installation should be entrusted to specialists. After delivering the device home, be sure to check the integrity of the cast iron heat exchanger. Even the presence of microcracks is a most dangerous situation for equipment. If they appear, the equipment will soon fail and the heat exchanger will need to be replaced.

Second group with steel heat exchanger

The Conord boiler with the design of a steel cylindrical heat exchanger made of cold-rolled metal is offered by the plant in single- and double-circuit versions. The service life is reduced compared to cast iron to 15 years. The designs use two automation options.

The first option: SIT automation from an Italian company known for its quality throughout the world. It is installed in the vast majority of all manufactured boilers in the European Union, such famous devices as: IMMERGAS, Fondital, Vaillant, and many others. The SIT valve allows you to guarantee a stable set temperature.

In addition, automation controls stable operation with a reduced gas pressure in the city pipeline. So the nominal value provides for operation with a pressure of 1.3 kPa, but a drop to 0.6 kPa is not a big problem and the Conord gas boiler continues to operate steadily, despite the fact that this is 46% less than required.

Single-circuit, with automatic SIT – heating only:

KSts-G-8S Heating capacity =8 kW KSts-G-10S Heating capacity =10 kW KSts-G-12S Heating capacity =12 kW KSts-G-16S Heating capacity =16 kW KSts-G-20S Heating capacity =20 kW KSts-G-25S Heating capacity =26 kW KSts-G-30S Heating capacity =30 kW KSts-G-40S Heating capacity =40 kW KSts-G-50S Heating capacity =50 kW

Single-circuit, with thermohydraulic automation

The second option is more budget-friendly, equipped with domestically developed AGU-T-M automatic equipment. AGU is an automatic gas burner device, consisting of nozzles and safety automation. The main manufacturers are Mimax and Tagonrog. ASU automation consists of:

1. temperature sensor;
2. igniter with thermo-bimetallic plate;
3. adjusting screw with lever;
4. gas valve;
5. block crane;
6. connecting parts.

Ignition order:

1. We check the draft, move the damper, light the igniter.
2. Press the gas valve and light the wick. We fix and do not release the button until the bimetallic plate heats up.
3. While continuing to hold the button, follow the lever. It will creep onto the inscription “on the button”, we need to wait for the moment when it is fixed.
4. Release the gas valve and set the required temperature using the control knob.

Domestic automation makes it possible to buy a Conord boiler a little cheaper. In contrast to European analogues, it has the simplest design. It is non-volatile - it does not require power from the electrical network. The starting process is carried out manually by igniting with matches or a lighter. By the way, thermo-hydraulic automation type AGU-T-M is widely used in Russian gas boilers

According to customer reviews, such automation is completely unpretentious; the Conord anapole boiler equipped with it is not “capricious”. In addition, it is not difficult to find spare parts on the market even far from city centers. The prices are also not satisfactory, for example, one of the frequently requested parts - a bimetallic plate - is found everywhere for no more than 100 rubles.

KSts-G-10N Heating capacity =10 kW KSts-G-12N Heating capacity =12 kW KSts-G-20N Heating capacity =20 kW KSts-G-25N Heating capacity =25 kW KSts-G-30N Heating capacity =30 kW

Double-circuit with DHW and SIT automatic control system

The Conord floor-standing gas boiler, when equipped with two circuits, copes with the task of heating buildings and at the same time is capable of preparing hot water used for household needs. The design uses the proven modulation function. Burner operation using modulation significantly increases the efficiency of hot water supply.

KSts-GV-8S Heating capacity =8 kW KSts-GV-10S Heating capacity =10 kW KSts-GV-12S Heating capacity =12 kW KSts-GV-16S Heating capacity =16 kW KSts-GV-20S Heating capacity =20 kW KSts-GV-25S Heating capacity =25 kW KSts-GV-30S Heating capacity =30 kW

Double-circuit with DHW, with thermo-hydraulic automation

KSts-GV-12N Heating capacity =12 kW KSts-GV-20N Heating capacity =20 kW KSts-GV-25N Heating capacity =25 kW KSts-GV-30N Heating capacity =30 kW

Secrets of High Performance

Modifications with thermohydraulics are non-volatile. The operating principle is based on the use of a thermostat. When the temperature reaches the declared value, the gas supply to the burner stops. This maintains the necessary heating of the coolant.

The devices are ideally adapted for harsh winters: they can stably maintain the required heating, the main thing is to correctly calculate the power. Efficiency increases due to:

• modulating burner;
• obtaining the optimal composition of the gas-air mixture;
• leaving the bulk of the heat for heating the coolant.

How to decipher the symbols

For example:

• KSts-GV-12
• KSts-G-10S

"K" is for boiler. "C" - made of steel. "C" - cylindrical firebox. "G" - gas. "GW" - heats the water. The number is the maximum power.

How to choose the right performance? For 10 sq.m you need 1000 W (ceiling height 2.5 m). This formula is suitable for rooms with average heat loss.

How they work

The firebox is made of 3 mm steel sheets. There is a water jacket, a gas burner unit and smoke pipes with turbulators, which increase the efficiency of the device. The gas burner unit operates automatically - the power is modulated. Basalt cardboard is used for thermal insulation. There is a thermometer to visually monitor the water temperature.

If the model is 2-circuit, then the chimneys are equipped with a coil for hot water supply. The input-output of the latter is located on the rear panel of the case. The diameter of the pipes is 2 inches / 5 cm. For hot water supply - 0.5 inches or 1.5 cm. Devices with a power of 8-12 kW have a chimney with a diameter of 11.5 cm. 16 kW - 15 cm. There are modifications with and without circulation pumps .

Important! The coolant of the system is plain water; the use of antifreeze is prohibited.

Gas boiler Conord - technical characteristics and features

The thickness of the steel sheets used to make the Conord boiler firebox is 3 mm. The material has a fire-resistant powder coating, thanks to which the service life of the boiler, as the manufacturer assures, is 15 years.

The warranty is valid for 3 years.

The efficiency of boilers of this brand is 90%.

Such a high indicator was achieved due to the installation of turbulators in smoke pipes.

The connections to the pipelines are located on the rear panel of the heat generator.

Their diameters are 50 mm or 2 inches (heating circuit connection) and 15 mm or ½ inch (for the DHW line).

The lowest-power model provides heat generation of 8 kW. The oldest representative of the line has a power of 30 kW. Intermediate values: 10, 12, 16, 20 and 25 kW.

The diameter of the chimney depends on the power of the device. For boilers with a heat output of up to 12 kW inclusive, it is 115 mm, for more powerful ones - 150 mm.

Heat generators of this brand have built-in expansion tanks with a volume of 8.5 liters. The maximum permissible coolant pressure is 6 atm.

An important feature of Conord boilers is the ability to operate at a gas pressure in the main line of only 0.6 kPa (usually the pressure in the distribution gas pipeline is maintained at 1.3 kPa)

How to maintain your warranty

In order not to be denied warranty obligations, you should not undertake installation and adjustment work. Connection, configuration, and first start-up are carried out by service center specialists. They also make a record of the work done in the device passport. Preventative maintenance should be carried out annually - this is also noted in the technical passport. Failure to maintain such records will void the warranty.

The instructions and connection diagram are provided for reference. Their presence in the package does not mean that the owner of the equipment can connect it himself.

What features must be observed during installation?

In order for the Conord gas floor-standing boiler to maintain its performance characteristics during the current warranty period, specialists certified by the manufacturer must perform the following actions:

1. install the unit in the boiler room;
2. configure the operation of the equipment;
3. Put the heating system into operation.

Afterwards, a record is made in the technical passport of the device indicating that the installation was put into operation in accordance with the standards.

Also, every year, specialists from the service center inspect the boiler for the purpose of preventive maintenance, and make the necessary notes in the passport. If there are no such marks, this will void the warranty period.

When installing equipment, the following points must be taken into account:

• it is important to install a base under the boiler, consisting of a poured cement screed and a laid metal sheet protruding 45 cm on all sides;
• for normal circulation of the coolant, it is necessary to install the pipe, which is located at the bottom, slightly lower than the heating radiators are located;
• when connecting welding, it is necessary to cut several threaded rings;
• the risers must be vertical, deviation is permissible within 3 mm per several meters of the entire structure;
• horizontal pipes that remove air must be laid so that there is a slope of 10 mm per meter;
• for every meter of pipe that carries out branches to heating devices, there must be a slope of 10 mm;
• It is imperative to protect the section of pipe that runs in cold areas;
• the diameter of the chimney should be larger than the outlet pipe, because such a design will ensure constant draft.

Installation nuances

Reviews from owners confirm that Conord may go out. Provoking factors:

• The burner is dirty. Before turning on the device, you should clean the nozzles with a brush or vacuum cleaner.
• There is not enough oxygen to start the burner. The air nozzles should be cleaned and the room ventilated.
• Thermostat contacts have oxidized. Cleaning needs to be done.
• Automation sensors are broken.

If the coolant cools down too much, you need to switch the thermostat to maximum or increase the flow of gas to the burner, if the instructions allow such an action.

Features of summer use

In summer it is necessary to turn off the heating circuit. To do this, turn off the tap at the coolant inlet. When one pilot burner is running, the water will heat up to 60 °C in 60 minutes. If water is not consumed, it will retain heat for about two hours - it can be used for domestic needs. When the device heats up and there is no active consumption of water, it is turned off so that the water does not boil.

Advantages of Conord boilers:

• The manufacturer promises more heat for less money;
• Gas consumption ranges from 0.44 to 2.74 for the steel version and from 1.99 to 4.8 m3/h for the cast iron version. A significant reduction was achieved by using innovative technologies in the creation of modulation burners;
• Straight lines – laconic design;
• Cost-effectiveness is determined, among other things, by good thermal insulation;
• Efficiency from 90% in steel to 92% in cast iron;
• Two types of automation;
• Security has a multi-level basis. The draft sensor in the design of the smoke collector instantly shuts off the flow of gas in the absence of natural smoke removal. The overturning of the draft, in the event of a discharge during a strong gust of wind, will not disrupt the stable operation of the Conord boiler if this phenomenon is of a short-term nature;
• Low noise performance.
• During the warm summer period, you can use only the second circuit without using the heating circuit. That is, the boiler works like a gas water heater in summer;
• Application of multi-layer protection on the cladding: zinc coating, followed by a layer of polymer included in the paint and a film of synthetic material completes the “pie”;
• Functionality: installed in both open and closed heating systems;
• Optimal ratio of cost and quality;
• The Conord boiler has successfully passed tests in accordance with Russian standards;
• Certified line of equipment.
