Repair of a gas boiler "Proterm": typical malfunctions and error correction methods

The Proterm brand has long been known in the Russian market: gas equipment regularly performs its functions of heating and hot water supply for both residential buildings and small industrial facilities. Sometimes the equipment fails. If the reason is a factory defect, then the boiler is better to be replaced immediately, but minor troubles are usually eliminated independently.

We will talk about how you can repair a gas boiler "Proterm" with your own hands, focusing on the self-diagnosis data and manufacturer's recommendations. We will show you how to identify a malfunction of equipment by code. We advise how to accurately determine the cause of the breakdown by decryption.

In our article you will find a description of the popular positions of the model range of boilers of this brand. Get acquainted with typical malfunctions in the operation of units for heating systems and with troubleshooting methods.

Overview of the Proterm brand series

If we consider gas-powered equipment, then at the installation site all boilers can be divided into two large categories:

• wall mounted - “Condensation Lynx” (“Lynx Condence”) and “Lynx” (“Lynx”), “Panther” (“Panther”), “Jaguar” (“Jaguar”), “Cheetah” (“Gepard”);
• outdoor - “Bear” (series KLOM, KLZ17, PLO, TLO), “Bison NL”, “Grizzly bear KLO”, “Wolf (Volk)”.

Despite the Turkish and Belarusian assembly, the quality of the equipment is European-style high.

Among wall models - 1- and 2-circuit atmospheric and turbocharged, with a power of 11-35 kW.

Floor models are made of steel or cast iron, equipped with injection or fan burners, can operate on natural and liquefied gas. The power range is wide - 12-150 kW - therefore, it is not difficult to choose a device for specific conditions.

The main purpose of the equipment is the organization of hot water supply and heating in private residential buildings, and some units are designed for industrial use

Each of the series has distinctive features related to design, dimensions, installation method, technical characteristics, additional functions:

• "Lynx" - condensation models work 12-14% more economically than non-condensation ones, therefore they are recognized as energy-efficient appliances for heating country houses and cottages.
• "Panther" - The latest models come with a convenient eBus communication bus and an updated security system
• "Jaguar" - the main advantages are the low price of the unit and the possibility of separate adjustment of two circuits - heating and domestic hot water.
• "Cheetah" - A popular wall model that can be installed both in the country, in the country or in a cottage, and in a city apartment.
• "Bear" - among representatives of various series - reliable units with a built-in boiler, a cast-iron heat exchanger and power up to 49 kW.
• "Bison NL" - universal models for the fuel used: work equally efficiently on gas, fuel oil or diesel fuel, power - up to 71 kW.
• Grizzly KLO - able to heat private houses and office premises with an area of ​​up to 1,500 m², maximum power - 150 kW.
• "Wolf" - An electrically independent boiler with a steel heat exchanger, stably supplies heat to cottages and residential buildings even in the absence of electricity.

According to customer reviews, Proterm units are reliable, efficient, convenient to install and operate, and with regular maintenance almost do not fail.

However, durable materials, good fuel and excellent assembly do not guarantee a perfect service, therefore, boilers of all the listed series will sooner or later require replacement of spare parts, cleaning or repair.

Error codes and ways to fix them

Thanks to the self-diagnosis function, modern boilers themselves determine the malfunctions, and information in the form of digital or alphanumeric codes is displayed on an electronic display. Having understood what is hiding under this or that code, you can from the table located in the installation and operating instructions.

An example of an electronic display of a Panther boiler with three digital blocks. The lower two digital displays display error codes for heating and domestic hot water

The Proterm brand produces many modifications for different series, and the error codes for different models may not match. To clarify the meaning, be sure to study the documentation of your unit.

Consider the errors of gas boilers "Proterm", the most common in popular models.

Models "Jaguar 11" and "Jaguar 24"

The main problems that users face are either sensor failures or changes in performance to critical ones. Consider the errors of the gas boiler "Proterm Jaguar", represented by two popular models with a capacity of 11 kW and 24 kW.

For example, when the coolant overheats to + 98 ° C, the boiler stops its operation, and an error is displayed F01.

Often, functioning is improved when the temperature returns to acceptable operating parameters. To resume operations, you need to restart the boiler by pressing the "reset" or "start" button

Often ignition is not carried out, and when you try to light the flame again, an error appears F04. There can be two reasons: a breakdown of the ionization electrode or a gas cutoff.

The easiest way is to check if the gas tap is open. If everything is fine with the fuel supply, the point is in the ionization system, which not everyone can repair on their own. The manufacturer recommends contacting a service center.

About blocked gas boiler chimney signal code F05. If air supply is resumed, the unit will continue to operate. The same error indicates changes in voltage: if it drops below 165 V, the boiler stops working until the operating parameters stabilize.

Codes F02, F03, F09 Notify about the malfunction of various sensors.

If the device still works if the hot water sensor breaks, then failure of the remaining sensors will stop its functioning

Replacing elements requires skill and experience - and if you do not possess them, we recommend that you contact a service center.

Quite often, an error appears on the display F10associated with pressure. One of the reasons is the breakdown of the pressure sensor, the replacement of which is better to be entrusted to gas workers with whom contract signed for service and gas supply. But if the point is to change the pressure parameters, the situation can be corrected independently.

The working pressure range is 1-2 bar. If the value drops below 0.3 bar or rises above 2.7 bar, the unit stops. To return it to work again, you need to return the operating parameters.

How it's done:

• find in the lower part of the boiler, near the contour nozzles, a feed valve;
• turn it counterclockwise until the pressure returns to normal;
• close the valve by turning clockwise - with the valve open, pressure will continue to rise.

It is better to strive for an indicator of 1.5 bar - positive results of actions will immediately be reflected on the display. If you overdo it and raise the pressure to 2.5 bar, the boiler will stop working again. During refueling, do not block the pipes to which the domestic hot water and heating pipes are connected.

Floor boiler "Bear"

Most of the malfunctions of the gas boiler "Bear is eliminated in two ways:

• automatically, after eliminating the cause (e.g. F.10 - short circuit of the temperature sensor in the water supply circuit, F.73 - short circuit on the case or shutdown of the hydraulic pressure switch, etc.);
• by pressing the failure key, which is located on the control panel (for example, F.20 - signal from the temperature limiter, F.28 - lack of ignition at the 1st start, etc.).

Some breakdowns or malfunctions can be adjusted / repaired manually without contacting the gas supply and service company representatives.

If the boiler refuses to turn on and work, does not heat the water, there are many reasons for this “behavior”.

Perhaps the gas valve is simply shut off or the power supply is turned off - then just turn the valve knob or resume power supply, and then repeat the ignition procedure

Sometimes the boiler "protests" due to incorrect temperature settings - it is necessary to adjust the temperature on the flow line, as well as the temperature of the hot water. If there is not enough pressure, you need to add water, and if there are air jams, bleed air from the radiators.

The situation changes if one of the functions remains valid, and the second fails. For example, the unit heats the water in the DHW circuit, but refuses to heat the house. Most likely, the program settings went astray and the boiler “believes” that the room is already warm enough. It is necessary to adjust the calculated temperature value in the house, and the heating circuit will start.

If, on the contrary, the heating is normal, and cold is pouring from the hot water tap, it is necessary to raise the temperature of the hot water.

One of the most alarming signals is water under or near the unit. This indicates a leakage. Most likely, they can’t cope on their own, and specialists will be required to solve the problem

If the boiler shuts down unexpectedly and the code appears on the display F.20, the manufacturer recommends unlocking the safety temperature limiter.

Procedure:

• Wait for the unit to cool.
• Using the device diagram, remove the front casing from the housing.
• Find access to the fuse under the junction box.
• Turn and remove the cap.
• Push pin as deep as possible.
• Press the key to clear the fault.
• After making sure that the boiler is working, replace the front panel.

With a regular recurrence of the problem, it is better to contact the service.

Wall-mounted boiler "Cheetah"

Error codes and recommendations for correcting them are the same for all Proterm wall-mounted boilers, but there are slight differences, as well as technical specifications.

For example, the operating pressure range is from 0.8 bar to 2 bar, therefore, only after lowering the values ​​below 0.8 bar will the unit give an error. In order for the device to work again, you need to add water to the heating system.

How to fill the heating system:

1. Open thermostatic valves.
2. Open the filling device.
3. Slowly pour in water until the pressure in the network reaches the operating parameters.
4. Remove air from radiators.
5. Cover the filling device.

During the procedure, do not forget to monitor changes in pressure values ​​on the display.

The maximum threshold at which the boiler stops is 2.8 bar. If this happens, reduce the pressure by draining the water through a safety valve.

One of the common mistakes is the failure of the valve regulating the gas pressure (error F.28-29), therefore, we will figure out how to fix the Proterm gas valve yourself.

It is necessary to turn off the gas supply at the inlet and the power supply. Then remove the front metal panel, find for gas valve repair and gently unscrew it.

The gas valve is a complex part consisting of several small elements - some of them can be removed for cleaning or replacement

If the valve is simply clogged with poor quality fuel, you need to disassemble it and wipe all the elements, being careful. If clogging occurred due to wear and tear of parts, the valve must be replaced. Most often, plastic elements break down, which can simply be changed.

The reason may also be hidden not in the valve itself, but in the power supply system - you need to check all the contacts and make sure that the power supply is stable.

To correct errors of the gas boiler Proterm Cheetah, you need to refer to the technical documentation, which sets out the manufacturer's advice. Upon failure gas boiler sensors and other elements require replacement.

If you are not able to replace the temperature sensors, electronic circuit board, fittings yourself, it is better to contact a service center. While the unit is under warranty, it is also impossible to do repairs on your own.
