Removing air pockets in the system

Simply filling the heating system with water is not enough; in order to fully start the heating system, it is necessary to release the accumulated air from it. Most modern heating boilers are equipped with an automatic air release system, but, as a rule, they work inefficiently and therefore, at least from the main components, it must be removed manually. Starting the heating system involves eliminating air pockets in the radiators and circulation pump.

It's better to start with batteries. To remove air pockets, a Mayevsky tap is usually installed on them. We open it and wait for the water to run. Did you run? Let's close. Such manipulations must be done with each heating device separately.

How to start a boiler with your own hands photo

After the air is removed from the batteries, the pressure in the system will decrease and the pressure gauge needle will drop. At this stage of work, the solution to the question of how to start the boiler involves re-filling the system with liquid.

Now, the most difficult thing is that starting gas boilers requires bleeding air from the circulation pump. To do this, the boiler needs to be disassembled a little. We remove the front cover and look for a cylindrical object with a shiny lid in the middle, which has a slot for a screwdriver. After we have found it, we put the boiler into operation - we supply it with electrical power and set the water heating controls to the operating position.

Relieving air from the circulation pump when starting the boiler photo

The circulation pump will immediately turn on - you will hear a faint hum and loud gurgling and many incomprehensible sounds. This is fine. As long as the pump is aired, it will be so. Take a screwdriver and slowly unscrew the cap in the middle of the pump - as soon as water starts seeping out from under it, screw it back. After two or three such manipulations, the air will come out completely, the strange sounds will subside, the electric ignition will work and start working. Check the pressure again and add water to the system if necessary.

Basically, that's it. While the system is warming up, you can begin to study the instructions in detail (if, of course, you have not already done so) and start debugging the system that involves starting the boiler. Everything is simple here - the batteries closest to the boiler need to be screwed on, and the ones farther away need to be turned on to their full potential. This debugging is carried out using control valves installed on the supply connection pipe to the heating radiator.

Parapet boiler Gepard and its technical data

The Cheetah gas boiler has two models that are especially popular. The technical designation of the boiler may contain the following inscriptions - 23MOV or 23MTV. Boiler home heating is very popular, so you need to choose equipment wisely.

The decoding of these designations is simple, but you need to know it:

1. 23 - rated power of the heating boiler;
2. MOV is a natural method for removing combustion products;
3. MTV is a forced method of removing combustion products.

The created gas boiler Proterm Gepard 23 MTV is intended for installation on the walls of apartments, private houses, cottages and dachas. The boiler is double-circuit, so there will be no problems with hot water. The presence of a liquid crystal display allows you to continuously monitor the operating process, the health of the boiler and the heating system.

The Protherm Cheetah 23 MTV wall-mounted gas boiler saves gas thanks to the ability to connect a temperature sensor or room thermostat. This model does not require connection to a chimney, which means it can be connected in almost any room, since it has a closed combustion chamber, and the waste combustion products are discharged through a horizontal coaxial chimney, led outside through the outer wall of the room.

Main technical characteristics:

• maximum hot water supply - 11 l/min;
• efficiency (efficiency) - 93.2%;
• range of manual adjustment of boiler power - 8.5 - 23.3 kW;
• rated boiler power - 23.3 kW;
• boiler type - parapet, wall-mounted, double-circuit;
• manufacturer - Czech Republic, Protherm company;
• recommended heating area - 240 sq.m.;
• approximate price - 38,892 rubles;
• warranty from the manufacturer - 24 months;
• gas operating pressure level - (0.5 - 3.0) bar.

In addition, the Proterm Cheetah 24 kW boiler, the instructions for which describe in detail the operating rules and temperature adjustment, is equipped with a display. The display shows information about the current status and malfunctions of the product.

What's wrong with too much power?

Let's look at setting the power of a gas boiler using the example of a double-circuit device Protherm Gepard 23 MTV. This model is an analogue of the Protherm Panther unit. The same manufacturer that produces Protherm gas appliances produces Vaillant brand boilers in another production facility. Their price is much more expensive, since they use higher quality components. In design and settings, Vaillant gas devices are very similar to Protherm models.

The operating instructions say that the useful thermal power of the Protherm Gepard 23 MTV boiler is adjustable from a maximum of 23.3 kW to a minimum of 8.5 kW. In production, the units are set to a power of 15 kW.

It is good if the heating system to which the gas boiler is connected has a power within the capabilities of the burner device, in our case - from 8.5 to 23.3 kW. But what if the existing radiators require less performance?

For example, let's take an apartment with an area of ​​50 m². For its heating there are radiators with a thermal power of 4 kW. The installers installed a gas boiler, but did not set the appropriate power. A 4 kW heating system will not be able to accept the installed unit performance of 15 kW. The large difference between the produced and the required indicator makes it impossible to automatically adjust the boiler. Then you need to adjust the device yourself.

Note! Experts categorically do not recommend installing a gas boiler whose power significantly exceeds the required one. This leads to cyclical operation of the unit and its rapid failure.

The characteristics of the gas boiler Protherm Gepard 23 MTV indicate that the efficiency of the device when operating at full thermal power is 93.2%, and at minimum - 79.4%. If the unit operates at a capacity of 4 kW, its efficiency will decrease even more. It turns out that almost a quarter of the thermal energy will “fly down the drain.”

Cyclicity of a gas unit and its consequences

Cycling or “clocking” of a gas boiler means that the burner, after being turned on, quickly turns off when the liquid reaches a given temperature in the pipe at the outlet of the unit. But the batteries do not have time to warm up. After a short period, the circulation pump pumps cold water from the heating system into the unit circuit, and the burner turns on again.

Another difficulty lies in the fact that low-power heating pipes have a smaller diameter and higher hydraulic resistance; accordingly, the coolant flows in them more slowly. If you heat the liquid in the heat exchanger with high power, it will reach the set temperature very quickly and the burner will turn off. At the same time, the rest of the water that did not have time to reach the burner will remain cold.

Automation without human intervention will not be able to react to the situation and adjust the optimal power of the device.

Note! With the correct settings of the heating system, the temperature difference between the inlet and return should be no more than 15ºC. Cycling of a gas boiler significantly reduces the service life of the unit and increases fuel consumption

It is known that the components suffer the most wear at the moment of switching on. Also, when ignited, a maximum portion of gas is supplied to the burner, most of which evaporates into the pipe. Frequent re-ignition of the burner further increases fuel consumption and reduces efficiency. To avoid this, it is necessary to adjust the power of the unit, that is, to equalize the performance of the gas boiler and heating system

Variety of gas equipment Proterm

This manufacturer offers consumers gas equipment of the following modifications:

1. Boilers "Gepard". In these wall-mounted units, the coolant moves forcibly.
2. Double-circuit devices "Tiger". They are also placed on the wall, but they are equipped with an electronic control system.
3. Heating devices “Grizzly” and “Bear” have automatic control of the combustion process and a special ignition system.
4. The Lynx and Leopard boilers are equipped with bithermal heat exchangers. They are also double-circuit.
5. Wall-mounted “Panther” devices are capable of functioning in closed heating systems.

Basic faults

All possible malfunctions are immediately detected by the sensor system and displayed on the display in the form of an alphanumeric code.

Unit errors occur for various reasons, including:

• Break or short circuit of one or another sensor.
• No flame.
• Lack of water.
• Stopping smoke output.
• Circulation pump failure.
• Fan stop, etc.

Most errors cause immediate blocking of the boiler for safety reasons. Situations are possible when there is no one in the house, and there is no one to respond promptly to the appearance of signals.

NOTE!

Therefore, the security system produces an emergency lock, which is reset by the owner when restarted. A complete list of error codes is available in the user manual.

It is a rather lengthy list, and there is no point in listing it in its entirety.

Device

The design of the Protherm Gepard 23 MTV boiler has a basic composition of components and structural elements that is typical for most convective installations of this type.

The main components of the unit include:

• Gas burner made of chromium-nickel alloy.
• Primary heat exchanger made of copper.
• A hydraulic group that includes a three-way valve, water replenishment and discharge devices, and other elements.
• Secondary heat exchanger made of stainless steel.
• Grundfos circulation pump.
• Turbocharger fan.
• Expansion tank with a capacity of 5 l.
• Electronic control board with microprocessor attached to an external display panel.
• A system of self-monitoring sensors that continuously monitors the condition of all boiler elements and signals the occurrence of errors.

The boiler operates according to a typical pattern. The coolant enters the heat exchanger, where it is heated to maximum temperature.

It is then removed and enters a secondary heat exchanger where hot water is heated. After this, the liquid enters the three-way valve, partially mixes with the return flow and acquires the set temperature corresponding to the set heating mode. After this, the OB goes into the external heating circuit.

Heating is provided by a gas burner, which automatically starts or turns off when the specified coolant temperature limits are reached.

The air supply for optimal combustion is provided by a fan, which simultaneously creates draft to remove gas combustion products. Air intake is made from the external compartment of the coaxial chimney, purchased separately.

The operation of all components is monitored by a system of sensors that monitor the presence of flame, gas or water pressure, and signal any failures or malfunctions. The occurrence of any problems is immediately displayed on the display with an alphanumeric code indicating a particular error.

A complete list of codes is available in the user manual.

Setting up the Proterm Jaguar boiler

All custom boiler operation settings are set on the front control panel of the boiler. There is also an LCD display to display the necessary information.

1. Rotary switch for setting the boiler operating mode and adjusting the temperature of the coolant in the heating system.
2. Rotary switch for setting the DHW temperature and turning the boiler on/off
3. Reset button and mode switching - economical/comfortable
4. LCD display to display information

When the boiler is connected to the mains, the LCD display shows the current pressure. When the boiler is on, to find out the current pressure, you need to press and hold the “eco/comfort” button for two seconds.

Setting the temperature on the Proterm Jaguar boiler

Rotary switches

The coolant temperature is changed by turning the right knob located on the control panel. When using radiators as the main heating source, the temperature can be from 38°C to 85°C. If underfloor heating is used as the main heating system, the temperature of the coolant is in the range from 30°C to 50°C. The maximum and minimum temperature parameters are set by the technician depending on the type of system.

To change the DHW temperature, use the rotary switch, which is located to the left of the LCD display. The temperature range can be from 35°C to 64°C.

Changing the boiler operating mode - economical and comfortable

To switch from economy mode to comfort mode or vice versa, you need to press the “eco/comfort” button once. After pressing, the display will show the selected operating mode - with the symbol “C” if the comfortable mode is selected or “E” when the economy mode is selected.

Changing the operating mode - comfortable or economical

When switching to economy mode, the boiler will turn off every time the water in the heating circuit heats up to the required temperature. In comfortable mode, when the set temperature is reached or exceeded, the boiler does not turn off, but modulates the flame.

F29.

The error appears during boiler operation and indicates loss of flame.

Recommendation: first you need to make sure that the gas line is not blocked by a tripped shut-off valve (for example, due to voltage instability) and that the pressure is normal.

Probable Causes

• Ionization sensor is dirty. It does not “see” the flame and does not provide a signal to the Proterm Gepard electronic module about stable operation of the burner. Cleaning clears the error.
• The grounding is broken. You should check the reliability of the contacts of the wires suitable for the sensor.

All other reasons causing boiler error F29 (gas fittings, control board, electrode corrosion) must be diagnosed and eliminated by a service technician. It is better for the user not to figure it out on his own.

Advantages and disadvantages

The advantages of Protherm gas boilers include:

• High quality manufacturing and assembly of all components and parts.
• Large selection of design and configuration options.
• The presence of many modifications that are optimally suited for working in difficult conditions.
• Environmental cleanliness, equipment safety.
• A self-diagnosis system is used that monitors the condition of all units of the unit.
• Economical consumption of gas and electricity. Non-volatile models are available.

There are some disadvantages:

• Dependence on the availability and correct connection to the power supply network, sensitivity to power surges or surges.
• High cost of spare parts, difficulties with supply in some regions.
• Low level of professionalism among technical personnel of service organizations.

IMPORTANT!

Complaints about the lack of training of service workers should not be understood as a design flaw in Protherm boilers, since the problem is of an organizational and administrative nature.

Clocking reduces the service life of the boiler and increases gas consumption

Putting the equipment into operation is the most difficult moment. At this time, components and mechanisms are maximally loaded. At this moment, starting currents operate, and an increased portion of fuel is supplied to the burner, part of which escapes through the chimney. During clocking, switching on/off occurs frequently, which means that wear on components increases, gas consumption increases, and efficiency decreases. Therefore, it is necessary to eliminate the cyclic operation of the gas unit immediately after detection. To do this, it is necessary to equalize the power of the boiler and heating system.

Regular maintenance of the boiler will extend its service life. How to do this correctly is described in the video

RULES FOR USE OF EQUIPMENT

water in the heating system (see installation design documentation).

Safety valve

8.11

The safety valve is located on the left, on the hydraulic group located at the bottom of the boiler. Water may flow out of the safety valve outlet (if the maximum pressure in the heating system is exceeded) or steam may escape. Therefore, it is recommended to organize a drain at the outlet of the safety valve, which must be connected to the sewage system of the given facility.

Warning:

It is prohibited to manipulate the safety valve while the boiler is operating. In addition, it is not permitted to use the safety valve to drain water from the boiler or heating system. Valve malfunctions caused by clogging from the heating system are not covered by the warranty.

Gas connection

8.12

The design of PANTHER series boilers is designed to operate on natural gas with a nominal pressure in the distribution network of 2 kPa, for which the specific calorific value is most often given from 9 to 10 kWh/m3. The internal gas distribution network and gas meter must be designed taking into account the user’s use of other types of gas appliances.

Warning:

It is recommended to seal the gas connection point to the boiler by tightening the union nut placed on the end of the gas valve pipe, placing a suitable gasket under it (see Boiler delivery set).

a

After completing work on supplying gas to the boiler, it is necessary to carefully check the gas tightness (tightness) of the connection made.

The lineup

It should be noted that Protherm gas wall-mounted and floor-standing boilers are available in different modifications. Therefore, it is worth considering widely used models in more detail.

Among the wall ones is the Jaguar model. The boiler is used for heating country houses and cottages, the area of ​​which does not exceed 220 sq.m. It also provides the organization of hot water supply. Heat exchangers are separate. The equipment mainly runs on main gas. Although the unit can be converted to run on liquefied fuel. For this you will need to buy a set of jets.

The technical characteristics of the Proterm Jaguar wall-mounted gas boiler are as follows: closed combustion chamber, efficiency is 90.2%, maximum net power is 25.3 kW, minimum net power is 10.5 kW, power consumption is 98 W, liquefied gas consumption ranges from 2.73 cubic meters/hour to 1.02 kg/hour.

The Panther model is also widely used. Hydraulic blocks of boilers are made of composite materials. This allows the strength of the structure to be increased significantly. The unit is equipped with a tank and pump. There is a “Comfort” option, which allows you to heat the water in just 5 seconds. Equipment power ranges from 12 to 35 kW. Many owners prefer to install a Protherm Panther 30 ktv gas wall-mounted boiler in their home to create an effective heating system.

The Lynx model is also chosen by many users. The series is characterized by two separate heat exchangers. It is possible to separately regulate the temperature level in each of them. There is an expansion tank with a volume of 7 liters. The Proterm double-circuit gas wall-mounted boiler is also equipped with a circulation pump. There are two versions of devices: with a power of 24 kW and 28 kW.

Among the floor-standing modifications are the “Bear” series of gas boilers. This is a single circuit type. Power is 18-44.5 kW. It can operate on main gas or liquid fuel. No electrical connection required. Most often used for heating industrial buildings. You can learn more about this model from our article “Gas boiler Proterm Bear - model range and advantages”

The Grizzly model is also widely used. The series is easy to operate. Designed for heating structures with an area of ​​up to 15,000 sq.m. Productivity is 150 kW. Operates on main gas. It is considered the most environmentally friendly equipment among boilers with similar power. But this series is dependent on the power source. There are also floor-standing models “Wolf” and “Beaver”.

To summarize, we can say that Proterm gas boilers are widely in demand among domestic consumers. All products are distinguished by high performance characteristics, reliability, durability, and at the same time, affordable prices. Which model to choose depends on the parameters of the heated room and the preferences of the owner of the house.

Connection diagram

Almost all thermostats existing on the modern market are relay. This means that they operate via a relay that opens and closes contacts based on a temperature preset by the user. As a theoretically connected thermostat, we will use an electric relay-type thermostat with dry contacts. Dry contacts are a term that means that in any state, closed or open, there is no voltage across the contacts.

To connect to the boiler, there are terminals on the thermostat; you need to connect the open and common ports. If they are not indicated in the manual for your specific model, you just need to ring the contacts with a tester. Next, we need to make sure that the thermostat can be connected to the boiler. Usually this is indicated directly in the technical documentation; if there is none, then the information can be easily found in any of the search engines.

The found electronic circuit diagram of the board indicates the location of the very jumper into which the thermostat will be connected to the boiler. Depending on the boiler model, you will have to unscrew several bolts to get to the required part. The block can be installed either on the control board or taken out separately. Connecting the thermostat for any of these options will be no different.

Next, you need to pull out the jumper, and in its place put the cable supplied with the thermostat (or purchased separately). This is a two-core wire with a cross-section of at least 0.75 square millimeters. The polarity when connecting does not matter. The cable is connected to the thermostat control unit into the normal open and common ports, as described above. The ports are located on one side of the control unit, and on the other there are ports for connecting the power supply cable. You can either purchase a new cable of the desired cross-section or use the complete one.

This completes the connection of the thermostat to the gas boiler. All that remains is to check the functionality of the system. On the thermostat we set the required air temperature in the room, the signal is transmitted to the control unit and, depending on the set temperature, the relay contacts close or open. When setting a temperature that is lower than the current one, the burner starts heating the water in the system; when setting a temperature higher, the burner, on the contrary, starts working.

Common errors and malfunctions

Some of the most common malfunctions of gas boilers can be eliminated independently, but the correction of the most complex errors must be entrusted to service center professionals.

Modern heating equipment from a manufacturer from Slovakia, the category of which includes single- and double-circuit gas boilers Protherm, is distinguished by its high reliability and variety of models. These high-quality and inexpensive boilers of European quality from the “middle class” are deservedly popular and are invariably in demand by domestic consumers.

Gas boilers from Protherm

The Protherm company appeared in 1991 in Slovakia.

Today it is part of the same holding with the recognized flagship company Vaillant, which allows us to confidently speak about powerful technological and consulting support. This condition has a positive effect on the product - with an average price range designed for the mass buyer, the quality of the equipment is not inferior to other representatives of this direction.

Gas boilers are one of the types of heating equipment produced by Protherm for export. All units undergo adaptation to the technological conditions of the area where they will be operated.

They are able to withstand power fluctuations and operate at low pressures of water and gas.

How does Proterm Gepard work when connecting thermostats?

When the Protrem Cheetah gas boiler operates without a room thermostat , heating of the rooms depends on the coolant temperature settings.

When connecting a Proterm thermostat , it becomes possible to set the desired heating temperature. It must be such that the unit can maintain it, regardless of the outside temperature. The controller will only control heating within the selected range.

Note! In the room where the room regulator is located, radiators cannot be equipped with thermostatic valves.

The Proterm unit with a two-position regulator is capable of maintaining a given heating temperature. The boiler will receive a signal to turn on or off depending on the temperature in the room in which the regulator is located.

When connecting a continuous regulator , the power will change smoothly to maintain the set room temperature.

The room regulator will control the temperature in the room and send a signal to the unit to turn off if the heat level has reached the set value or to turn on if the temperature decreases.

The most modern and accurate is equithermal regulation . This is done by a thermostat with an outside temperature sensor. When such a device is connected to a gas boiler, the latter will regulate the temperature of the coolant depending on the conditions outside.

If the operation of the unit is controlled by an equithermal regulator, it is not recommended to set the maximum coolant temperature - this will significantly reduce the efficiency of the system.
