Instructions for installing and operating a Ferroli gas boiler.  Ferroli Zews electric boilers: review, instructions, technical characteristics Ferroli gas boilers technical characteristics

Italian gas heating boilers Ferroli are only a small part of the range climate control equipment, which is produced at the enterprises of this company. The Ferroli company itself was founded in 1955 in the small town of San Bonifacio, and since then it has grown from a small factory into one of the leaders in the national and European heating equipment market.

Boilers from Ferroli

Wall and floor models

Despite the very wide range of installations for heating residential and production premises, the lion's share Ferroli's profits come from gas heating boilers– wall and floor. At the same time, it is in the wall-mounted segment that the greatest diversity is observed.

This is due to the fact that compact wall models have a number of advantages in use:

• Firstly, such a boiler can be installed directly in a residential area, since it does not require a separate boiler room.
• Secondly, If previously the power required for heating could only be provided by large-sized installations, today, thanks to the use of modern technologies, even a small boiler can heat up to 300 square meters living space.
• Easy to install– another argument in favor of choosing small models mounted on load-bearing wall premises. Of course, you shouldn’t install the boiler yourself, since this requires special permission - but the cost of installation directly depends on its complexity!

Advice! So that you can monitor compliance with the quality of installation of the heating device, we recommend that you study the video posted on our website. Any work requires verification, and without the proper knowledge you will not be able to carry it out!

Price also plays an important role. Although Ferroli products cannot be considered the cheapest price segment, but still among the mounted models you can choose a completely affordable option.

Application and equipment

Ferroli boilers can be used in the following areas:

• Firstly, for heating private houses and cottages. As we indicated above, the power is quite sufficient.
• Secondly, the compact dimensions allow these units to be used even in apartment buildings for organizing individual heating.

To effectively implement these functions, Ferroli installations are equipped with the following equipment:

• Combustion chamber open or closed type(respectively, they are marked C or F).
• Bithermic heat exchange tank made of copper alloy.
• Automatic control system for the burner operation on a meringue microprocessor unit.
• Protection against freezing, overheating or internal scale formation.

Also included in the basic package is a unit responsible for flame modulation and an ionization system for controlling combustion intensity. Thanks to this, Ferroli boilers are completely protected from possible gas leaks.

The appearance of the boilers, as well as the location of the main elements, are shown in the photo. The instructions included with each product clearly demonstrate the process of connecting the boiler to the network, as well as the sequence of adjusting its main functions. should be done only by specialists, and no amateur performances!

Note! The product line includes models designed to operate on both liquefied and natural gas. You should take this into account when choosing a unit for your home or apartment.

Main series

DIVAtop

The list of heating equipment models released to the market by Ferroli is very wide. Therefore, in this article we will consider only the most significant series from the entire product range.

The DIVAtop series is one of the first to be introduced to the market Russian Federation. This series is based on high-performance double-circuit boilers for household use.

• DIVAtop devices are different stylish design housings, which allows them to be installed directly in residential premises.
• A key design feature of devices from the DIVAtop line is the presence three way valve equipped with a separate servo drive.
• A heat exchanger for a hot water supply system, which has a plate design, is responsible for effective heat transfer.

DOMIcompact

Units from the DOMIcompact series are focused not so much on heating (although they perform this function quite effectively), but on the fastest possible hot water. At the same time, the specially designed heat exchanger installed in the boiler does not overheat, and virtually no scale forms in it.

• The DOMIcompact boiler can be controlled using either conventional control knobs or a liquid crystal display. A built-in chimney can be used to remove combustion products.
• The DOMIcompact-B modification includes a more modern heat exchanger. Using the energy of steam condensation allows you to increase the power of the boiler, while reducing fuel consumption.
• This modification also significantly reduces the percentage of emissions of harmful gases into the atmosphere.

Econcept

The Econcept series represents the embodiment of the ecological paradigm. Distinctive features of the Econcept series boilers are:

• Heat exchanger-condenser made of high-strength aluminum.
• Sintered metal burner with continuous modulation, equipped for use different types gaseous fuel.
• Microprocessor control system for boiler operation, adapted for installing a weather-dependent control system.
• A plate heat exchanger that provides the fastest possible heating of water in the hot water supply circuit.

At the same time, the Econcept series is characterized by minimal emissions, as well as very impressive safety and reliability indicators.

Design and adjustment of Ferroli Domina gas boilers

The Ferroli Domina F24 E wall-mounted gas boiler with a copper heat exchanger for heating and hot water, with electronic ignition and flame control, is a new high-performance device with a closed combustion chamber (all the air entering the heater is taken from outside the room), running on gaseous fuel.

The Ferroli Domina F24 E boiler is designed to produce bitter water for heating and hot water supply. The unit uses advanced technological systems, such as electronic regulation, control and safety devices.

A distinctive feature of the device is the built-in electronic ignition and combustion control device, which provides fully automatic and safe work burners.

Fig.1. Structure and elements of the Ferroli Domina F24 E boiler

Differential air pressure sensor

The differential air pressure sensor is a safety device; it allows the burner to ignite only after checking the operation of the fan.

If the difference between the pressure of the exhaust combustion products and the incoming air is not equal to the minimum calibration value of the sensor, then the sensor contacts will remain open and gas valve won't open.

In addition, the boiler's electrical circuit is designed in such a way that if the pressure sensor contacts remain closed when the fan stops, the burner will not start.

Operating principle gas boiler Ferroli Domina F24

The Ferroli Domina boiler is suitable for operation on two types of combustible gas: methane or propane (liquefied gas).

The gas mode for operation is selected when ordering or changed at the installation site. The boiler works with advanced systems: electronic control, safety and control equipment.

When the room thermostat requests heat, the pump and burner turn on. Using an electronic flame modulation system, the boiler power gradually changes until it reaches set temperature submissions.

If the power required in the heating system is below the minimum boiler power, when the flow temperature exceeds the set value, the burner is turned off and the electronic system allows it to be turned on only after 2 minutes.

When the temperature set on the room thermostat is reached, the burner turns off and the circulation pump continues to operate for another 5 minutes to ensure better heat distribution in the system.

If hot water is drawn into the water supply system during the heating phase, the electrical heating circuit is automatically switched off and the hot water supply circuit is switched on.

Throughout this entire stage, the circulation pump of the heating system is stationary, and the Ferroli Domina boiler supplies water at the set temperature.

The device maintains the water temperature of the water supply system constant, even when drawing various quantities, by modulating the torch.

Every time after the hot water production of the water supply system ends, the heating system pump starts for one second in order to prevent it from blocking, especially in the summer.

Adjustment of Ferroli Domina boilers

Adjusting the pressure and flow of the main burner

The Ferroli Domina wall-mounted gas boiler operates on the principle of flame modulation. The system has two fixed pressure values, minimum and maximum, which must be as specified for each type of gas.

The minimum pressure adjustment must be carried out first to ensure correct ignition of the burner. After this, the maximum pressure is adjusted. Any change in the minimum pressure affects the maximum pressure value.

Adjusting the minimum and maximum pressure using the Honeywell V K4105G gas valve:

Connect the appropriate pressure gauge to the pressure tap located after the gas valve.

Disconnect the pressure compensator.

Remove the protective cap.

Set the potentiometer (on the main panel) to minimum value(counterclock-wise).

Operate the Ferroli Domina boiler in heating mode.

Adjust the minimum pressure by turning the screw clockwise until the desired value is obtained.

Set the potentiometer (on the main panel) to the maximum value (clockwise).

Adjust the maximum pressure by turning the screw counterclockwise until the desired value is obtained.

Connect the pressure compensator.

Replace the protective cap.

Adjustment maximum power heating systems:

This adjustment is performed only on the electronic board using the adjusting screw RZ, starting with the system temperature below the maximum of the control thermostat (system temperature 50-60°C).

Connect a special pressure gauge to the pressure tap located in front of the gas valve; Turn the temperature control screw to the maximum value, then set the required pressure value.

After completing this operation, turn the Ferroli Domina boiler on and off 2-3 times using the thermostat. Every time you start, check that the pressure corresponds to the set value and that the burner ignites correctly.

If necessary, make additional adjustments until the pressure stabilizes at the set value.

When igniting the burner, to control the set pressure, set the control thermostat knob to the maximum value, otherwise errors will occur.

Adjusting the temperature of the heating system and room:

The water temperature of the heating system is regulated by turning the corresponding knob.

When turning the knob clockwise, the temperature of the heating water increases, and counterclockwise, it decreases.

The temperature can vary from a minimum of 35°C to a maximum of 85°C. We recommend not to operate the Ferroli Domina boiler at temperatures lower than 45°.

Room temperature control is achieved by setting the room thermostat knob to the desired value.

The thermostat automatically controls the boiler, temporarily turning off the power supply line, depending on the heat demand of the room.

OPERATION AND REPAIR OF BOILERS

Proterm Panther

Ferroli has gained wide popularity among users due to its affordable cost and huge range of products. Another important advantage of such units is that they are absolutely adapted to domestic operating conditions. In the article we will look at what a Ferroli gas boiler is and note its distinctive features.

Wall-mounted gas boiler Ferroli DIVATOP series

Specifications

In order to choose the most optimal option for a heating device manufactured by Ferroli, a number of parameters should be taken into account:

1. Location - there are both wall-mounted and floor-mounted units. The first are intended for autonomous heating of an apartment or private house. The latter are characterized by high productivity and are installed in large rooms.
2. The number of circuits, a mounted Ferroli double-circuit gas boiler and a floor-standing analogue are used for simultaneous heating of the coolant and DHW. Units with one circuit are connected only to heating system. As an exception, we can note models with built-in or separate installed boiler indirect heating.
3. Principle of operation - boilers that include an atmospheric burner are distinguished by a simple operation scheme and unpretentious operation, which explains their low price. Devices of the type with a closed combustion chamber have a forced supply of air masses. As a result, productivity increases and gas consumption decreases. In order to ensure the functioning of devices with a closed combustion chamber, electrical energy is required.
4. Heat exchanger - units made of steel are characterized by high performance and heat transfer. That is why they are often installed indoors industrial type. Boilers with a cast iron heat exchanger have much lower efficiency, but they will last longer.

Condensing units are connected to a horizontal one. Models with closed fireboxes must be connected to the home's energy saving system. By means of a fan, air is drawn in and combustion products are removed.

Advantages of Ferroli gas boilers

As the distinctive features of the units produced by the Ferroli manufacturer, first of all, it should be noted their reliability, innovative technological developments, as well as absolute adaptability to Russian conditions.

Condensing gas boiler Ferroli ECONCEPT tech 25 A

Each model includes a digital microprocessor control system. In addition, it is provided automatic adjustment permanent flame modulation. The surface of the combustion chamber and heat exchanger is coated with a special compound that protects against corrosion. Its key element is aluminum. The burner has a steel head. The inside of the chamber is insulated by special material, which is environmentally friendly and absolutely safe.

Another feature of boilers of this brand is the presence of a frost protection system and an anti-lock pumping system for hot water supply and heating.

Boilers can operate on both natural gas and liquefied gas. The devices are also very easy to maintain - all elements are placed in such a way that they are easily accessible. If necessary, you can create remote control of their operation - to do this, you just need to connect the control panel.

Condensing wall-mounted gas boilers Ferroli

The high quality of Ferroli heating units is especially noticeable in condensing boilers, whose productivity is very high, efficiency reaches 100%. The operating principle is based on the use of thermal energy of steam, which is formed as a result of the combustion of blue fuel. The temperature of the flue gases is used to obtain additional thermal energy, which in conventional models flows into the chimney.

Distinctive features of condensing double-circuit and single-circuit Ferroli units in wall-mounted version the following:

1. Gas consumption is reduced to a minimum. The design of the device has a modulation burner. The automation independently regulates the gas supply based on the specified temperature regime and seasons.
2. Thanks to the control system, you can choose the intensity with which the house will warm up depending on the time of day for several days in advance. Some models have special outlets for connecting underfloor heating. Automation heats the coolant simultaneously in both heating circuits.
3. Wall-mounted gas-fired units from the Italian manufacturer Ferroli are completely dependent on electrical energy. With frequent voltage drops, the microprocessor board quickly breaks down. If the voltage drops, the heating is turned off and the station must be restarted. This phenomenon is a significant disadvantage of Ferroli boilers; it is because of it that boiler ratings fall.

The sensitive burner in condensing-type boilers can also operate at low gas pressure. The coolant can be water or.

Wall-mounted units with atmospheric burner

Atmospheric boilers are traditional appliances, in which there is open camera combustion and burner, the air supply to which is carried out through natural circulation. Air masses are taken from the room, which serves the needs of the boiler room.

The advantage of wall-mounted atmospheric gas boilers is their simple and convenient design. As a minus, it should be noted the high gas consumption and low productivity. There is nothing complicated in installing wall-mounted boilers classified as atmospheric.

The package includes important elements, which affect the performance of the system as a whole. This is an expansion tank, gas valve and burner. Electric or piezo ignition is provided. Piezo ignition is considered a more economical option, since the pilot burner is activated only when the flame dies out.

Ferroli boilers - Experts answer questions

Question:

The Ferroli Domiproject f24 boiler worked fine for a year. Then it began to work intermittently. It works for a few seconds, goes out and lights up again, and so on all the time. Both during heating operation and during DHW operation. I checked the chimney system, everything is fine. Replacing the pressure switch did nothing. I removed the plugs on the top cover of the boiler, but it didn’t help. When I remove the sealed chamber cover, it works fine. What
could there be a reason?

Answer:

If the boiler does not show any error and the voltage is more than 200 volts, then the heating heat exchanger is most likely clogged. You can check by connecting the heating sensor for a few minutes in the air or, which is easier, by reducing the gas with a tap in front of the boiler. If the burning interval has increased, then flushing is necessary.

Question:

The Ferroli Domiproject f 24 boiler cannot cope, the coolant temperature does not rise above 40, and the potentiometer reads 70. The heated area is 70 m2. And it's 12 degrees in the room. What should be done?

Answer:

This means there is not enough flow. Here's what you need to do: check the return filter, check the pump power and find out if the main heat exchanger is clogged.

Question:

When the heating system is turned off, the pressure in the system drops to 0 (approximately in a day to 0.5 with the ECO turned off; or to 0 with the ECO turned on in a few hours) and the hot water supply accordingly also turns off. I add water. After a while the pressure drops again. When the heating is on, the pressure does not drop or does not drop very noticeably. Recharge once every 1-2 months.

Answer:

First of all, you need to pump the expansion tank with nitrogen - air to 0.8 Bar - at a pressure on the water pressure gauge in the boiler = 0. And then look for a leak, check the blast valve to see if water is leaving it.

Question:

After installing the Ferroli Domiproject 24 boiler, the hot water pressure was almost at the same level as the cold water pressure. Six months later the pressure dropped. What could be the reasons? If this is scale formation in the secondary heat exchanger, then what should I wash it with and how, as well as how to avoid scale formation?

Answer:

This boiler does not have a secondary heat exchanger, it is bithermic, and scale forms in it winter mode, especially when the flow sensor is not working and there is a leak DHW water. You can wash it with sulfamide acid, for example, or hydrochloric acid.

Question:

Please tell me, if the boiler has completely gone out, nothing is burning or turning on, although the 220 board comes with the fuses and varistor intact, what burned out?

Answer:

Pulse block power supply on the board.

Question:

The Ferolli boiler worked normally for 2 weeks, after the arrival of a technician from service center For the first start, the hot water ignites and lights up the flame. If I tighten the gas valve, it works fine. The heating works normally even with the gas tap fully open. How to fix it?

Answer:

If you can adjust the gas valve yourself, the instructions describe the procedure quite well; if you are not sure, it is better to call a specialist again. You need to set the MAX on the gas valve - use the “reset” button to go to test mode, press the heating knob three times in MAX if the flame blows out with the key at 10 counterclockwise, and then use the “reset” button to go to test mode, adjust the power for heating and ignition using the heating temperature knob - heating power - water temperature knob - ignition. Procedure 5 minutes

Question:

Hello, I have a problem with the hot water supply: the ventilation hatches are regularly turned off; the ventilation hatches are already open and the heating turns off with the hatches closed; the pipe is clean; the fan works; and sometimes it displays the error: the draft sensor is faulty. What should I do?

Answer:

If everything is in order with the chimney, then the pressure switch needs to be checked.

Question:

Ferroli boiler in hot water supply mode. Periodically, in standby mode, the upper and lower LEDs begin to blink (simultaneously). When you turn on the hot water, after 3 minutes the burner goes out, although the burner on LED is on. Also, periodically, when hot water or heating is turned on, the upper and lower LEDs begin to flash alternately. ON-LiNE stabilizer with output inverter
sine wave and 220. The boiler has one heating season.

Answer:

First, check the dual temperature sensor.

Question:

The Ferroli Domiproject boiler has been in operation for 1 month, worked fine and one night began to make strange sounds similar to strong boiling (it was heard through closed door). The unit was turned off until the morning, in the morning I checked the pump, the supply voltage (there is a stabilizer) - everything is normal. I started the boiler - the sound returned, I think scale had formed - I washed the heat exchanger, nothing helped - at a temperature of 40 and above, cacophony begins, if you open hot water, the sound disappears, when you close it, it appears again.

Answer:

Perhaps the return filter is clogged, low flow through the heat exchanger - the heating system.

Question:

When the heating circuit heats up above 55 degrees, the heat exchanger begins to make noise, as if it were boiling. Can high circulation in the heating circuit cause the temperature in the DHW to exceed? I set the temperature with the heating potentiometer from 45 to 60 degrees. For half an hour the boiler rose to temperature, then began to make hissing sounds, did not wait any longer, turned the knob to 55, the burner turned off.

I observed the parameters of the gas pressure, after a fire in the firebox, the pressure on the burner maximum, after about 10 seconds, drops to a minimum, so it burns for about five minutes, then it begins to add 10 pascals and stops. Somewhere at three millibars, it starts to make noise, works for another three minutes, then reaches a temperature of 55-60 degrees and turns off.

I cleaned the boiler (pump, heat exchanger, furnace, filter) - it didn’t help, then I set the lower gas pressure setting to 40% below the nameplate - the noise disappeared at 60 degrees. Paradox - take off the lid closed chamber combustion - the boiler does not make noise. When you put it on, it starts to make noise. What could it be?

Answer:

Or scale in the heating circuit or some kind of dirt. You need to rinse it with a booster, if it helps, good, if it doesn’t help, install another heat exchanger or another boiler with separate heat exchangers.

Question:

I have the following problem. Ferroli boiler DOMIproject C24. When the hot water is turned off, the heating circuit circulation pump may not turn on. Does not turn on until the burner is ignited for heating. The water in the boiler boils and the red LED starts flashing. The boiler breaks down. This happens several times a day. How can you solve this problem yourself?

Answer:

Clean the DHW flow sensor.

Question:

2A fuses burn out on the Ferroli DOMIproject C24 boiler. What can be done?

Answer:

Fuses cannot burn just like that; you need to look for where the short circuit occurs that leads to the fuse burning out. First, check the operation of the pump.

Question:

I bought a Ferolli boiler and installed it. Uninterruptible power supply SMART APC 750. Hot the water is flowing no problem. When I turn on the heating, it displays the error “overheating protection has tripped.” The pump is not working. What to do?

Answer:

Unlock the pump shaft. If this does not help, connect the pump directly. If it does not work, replace the pump. If it doesn't help, pay for repairs.

Question:

There is such a problem. When the hot water is turned on, the Ferroli Domiproect F24 boiler periodically turns off the heating and then starts again. What could be the problem? The board has been replaced.

Answer:

It is necessary to adjust the operation of the gas valve - minimum power.

Question:

Tell me what could be. When I turn on the boiler, the red and yellow lights immediately turn on (they blink frequently, what could it be besides the sensor? And another related question, if you remove and bridge the contacts that go to the sensor, the blinking of the lights should stop, if the problem is in the sensor, am I thinking correctly or Am I wrong?

Answer:

If the error does not disappear by jumping the wires, the sensor must be replaced.

Question:

Ferroli DOMIcompact c24 boiler. Relieves pressure to 0. There are no leaks in the system. It seems to reset when the hot water is on. Cold water supply pressure is 2-3 atmospheres. The boiler worked for two years.

Answer:

There may be a breakdown between the circuits, and the pressure drops below the cold water supply pressure due to ejection. You most likely have a different problem! The expansion tank has lost air. The heating system cools down and the pressure drops when you turn on the DHW.

Question:

Tell me, is it possible to adjust the minimum pressure switch so that the boiler turns on at a pressure of 0.8 bar?

Answer:

There is an adjusting screw on the pressure sensor under the cap on top.

Question:

Ferroli Domicompact boiler C 24 kW. There is a problem. The chimney is clean, the water and gas pressure are normal, but the boiler works as it pleases. I set it to 45C and it heats up either normally or like crazy. Turns on at any time intervals. There is a leak from the make-up tap into the heating system, but after refilling I turn off the DHW supply and outlet taps. What do you advise?

Answer:

Repair the feed tap, check (replace) the NTC sensor. According to NTC data, the boiler turns on for heating. As t changes, the NTC resistance changes. If the readings are incorrect, then the boiler switching on is inadequate. Alternatively, you can check the variable on the board.

Question:

Ferroli domicompact F 24 boiler, 4.5 years. Last year the heat exchanger leaked. They called a repairman and he soldered it. This winter, another problem appeared: The heating temperature is set to 60 C, and the pipes heat up to 80 C. At the same time, the pressure goes off scale to 3.5 Bar. Or it drops to 0. Tell me what the problem is?

Answer:

Replace the NTC, bleed the volume compensator and perform preventative repairs.

Question:

The Ferroli Domicompact F24 boiler operates with the room thermostat jumper removed. The problem arose when I connected the thermostat (COMPUTHERM Q7 RF). For some time everything worked fine, then after opening the contacts in the thermostat receiver, the boiler continued to work as before. Depending on the position of the temperature regulator, heating occurs, heating is turned off, and the pump circulates water. Thermostat
connected correctly and works on short circuit-open circuit - checked by a tester.

Moreover, when to completely turn it off i.e. The jumper is removed, the boiler is working, the DHW regulator is in what position it is on off, it doesn’t matter - everything is the same. Sometimes after turning on the DHW it turns off and then (as expected) it works normally from the thermostat. Sometimes, after turning off the thermostat, it tries to start, but immediately turns off, this happens several times, after which the pump runs for 6 minutes and the boiler turns off. If possible, tell me what's the matter?

Answer:

Check the wires going from the board to the room thermostat connector. When the circuit is closed (or the thermostat has closed the contacts) - the boiler works for heating, when it is open - it waits for the contacts to close to turn on the heating.

Question:

There is such a problem: the Ferroli DomiCompact F24 boiler works perfectly from a 220V network, but when connecting a Leoton 500 watt converter, the gas does not ignite. What to do?

Answer:

Turn the fork over.

Question:

I have a Ferolli DOMIcompact C24 boiler. Everything was working fine, and then suddenly, when the heating of the apartment was turned on, the pressure on the boiler suddenly began to rise to 3 bar. To make it clearer: The boiler is not working - I set the pressure to 1 (I hear a clicking sound, the light stops blinking). I set the temperature to 40. The device starts up and begins to heat the water.

Literally, in 5 minutes the pressure sharply increases to 2.5 or more. (This was not the case before). I drain water from the system (through the return valve), thereby reducing the pressure. And I do this until the water heats up to the desired temperature. When the water has warmed up, I turn off the water from the tap and set the pressure to 2 bar. When the boiler operates constantly at this temperature and does not turn off (in winter), the pressure remains unchanged (sometimes increases slightly).

And when you turn off the heating of the heating system, the pressure drops below 1 and the device does not ignite. You have to open the feed tap and add water to increase the pressure to start the boiler. It's summer now and the heating system isn't working. I set the pressure to 1.5 to heat the water. This is how it has been for 2 months now. Tell me, what is the problem?

Answer:

The problem is the lack of air in the expansion tank.
