__________________________________________________________________________

Installation, connection and start-up of the boiler Proterm Panther

Mounted gas boiler Proterm Panther 25 KTV with forced exhaust of combustion products and model 25 KOV with natural exhaust, running on natural gas or propane, are designed for heating and hot water supply country houses, cottages, small garden buildings, utility buildings and other facilities that are equipped with a heating system with forced circulation of the coolant and water supply.

Fig.1. Hinged gas boiler 25 KTV PANTHER

1 - closed (sealed) combustion chamber (turbochamber); 2 - atmospheric type burner; 3 - heat exchanger; 4 - circulation pump; 5 - air vent; 6 - heat exchanger of the DHW system; 7 - three-way valve drive; 8 - gas valve; 9 - ignition electrodes; 10 - control electrode; 11 - ignition unit; 12 - control panel; 13 - heating temperature sensor; 14 - emergency temperature sensor; 15 - thrust sensor; 16 - fan; 17 - water pressure sensor

The boiler is designed for operation in the temperature range from +5 to 40 °C and relative humidity up to 85%.

The temperature of the outer surfaces of the boiler unit (side and top covers) during boiler operation must not exceed the ambient air temperature by no more than 50°C.

When placing the boiler, it is not allowed to place objects near it:

From flame-retardant materials - at a distance of less than 100 mm from the surface;

From flammable materials, such as fibreboard, polyurethane, lightweight PVC, synthetic fibers, rubber, etc. - at a distance of less than 200 mm from the surface.

A free space of at least 1m must be left in front of the boiler for maintenance work.

At the Protherm Panther 25 KTV boiler, the removal of combustion products and the supply of combustion air is carried out by a special coaxial pipeline or separate pipelines.

From standard parts, you can make a coaxial chimney for almost all laying options. The length of the chimney, the type and number of sections must be agreed with the service organization.

The chimney must be laid in such a way that the condensate from the combustion products can be removed. For this, special sections are designed that are built into the chimney route.

The gas boiler Proterm Panther 25 KOV is designed to discharge combustion products into a natural draft chimney. The boiler is connected to the chimney using a pipe with a diameter corresponding to the size of the chimney pipe.

It is not allowed to install objects in the pipe that restrict the passage of combustion products (for example, different kinds heat recovery heat exchangers, etc.).

Mounting gas boiler Proterm Panther

The Protherm Panther 25 KTV (KOV) boiler should be installed in closed heating systems with water as the heat carrier. The nominal pipe diameter of the system is selected based on the characteristics of the pump. The pipeline is designed according to the required capacity of this system, and not the maximum
boiler heat output.

In this case, the flow rate of the coolant must be such that the temperature difference between the supply and return is no more than 20 ° C. The minimum flow rate of water in the system is 500 l/h. The piping system must be designed in such a way as to ensure the removal of air from it.

Air vents are located at the highest point in the system and on all radiators. The heating system is filled to a pressure of at least 1 bar. The recommended pressure range in the system is 1.2 - 2 bar.

The expansion tank of the boiler is designed for a heating system capacity of 95 liters. In larger systems, another membrane-type expansion tank should be installed. Heating radiators can be equipped with thermostatic valves.

If the unit is controlled by a room regulator, thermostatic valves are not installed in the room where the room regulator is located. Before installation, the system must be thoroughly cleaned.

DHW system

The water pressure in the DHW system must be in the range of 1 - 6 bar. If the pressure exceeds 6 bar, a pressure reducing valve must be installed on the inlet. At high hardness tap water it is recommended to take appropriate measures to reduce it.

Connection pipes have external threads. They must not be loaded with the weight of the pipes of the heating system, the DHW system or the gas supply. The installation dimensions of the connecting pipes (height, distance from the wall and between individual inlets and outlets) must be exactly observed.

In the lower part of the boiler there is a hydraulic group, which is equipped with a safety relief valve, a valve for filling (filling) the system and a drain valve. If the maximum pressure in the system (2.5 kgf/cm2) is exceeded, water may flow out of the safety relief valve or steam may be released.

Connecting the boiler to heating system it is recommended to carry it out in such a way that during its repair it is possible to drain the water only from the unit. Make-up of the heating system (in small quantities) can be carried out using the make-up tap.

The drain valve is designed to reduce the water pressure in the boiler during possible repairs. It is possible to drain water from the boiler with this tap only partially. Complete draining of water or the entire heating system, as well as re-filling, must be carried out using valves (plugs) for filling and draining installed in
certain places in the heating system.

Filling the Protherm Panther boiler and system with water should be done in the following order:

Check that the pressure in the DHW system is higher than the water pressure in the heating system.

Carefully open the filling cock in the hydraulic group and at the same time monitor the pressure increase on the boiler pressure gauge. The faucet is opened by turning counterclockwise, clockwise - closes.

When the required pressure is reached, the filling valve must be carefully closed and the water pressure must be checked to see if the water pressure is rising (the valve must be completely closed).

If the DHW pressure in the water supply is the same or lower than the pressure in the heating system, water may leak into the water supply, which is unacceptable. This can be prevented by setting check valve on the water supply pipe to the boiler.

During repairs, unfavorable building layouts, etc., it is possible to connect the boiler to the heating system, hot water system and gas supply with special flexible hoses.

When using flexible hoses, they must have a length of no more than 0.5 m, protected from mechanical stress and damage, exposure to aggressive substances. At the end of the service life of the hoses, they must be replaced with new ones. To connect the boiler to copper pipes, you can use a special connection kit of shaped copper pipes with fittings.

Tube dimensions:

OV inlet and outlet - tube diameter 22 mm.
- DHW inlet and outlet - tube diameter 15 mm.
- Gas connection - tube diameter 22 mm.
- Safety valve connection - tube diameter 22 mm.

Gas connection

Size 25 KTV (KOV) - ZP is designed to operate on natural gas with a nominal pressure in the distribution network of 1.8 kPa and a calorific value of 35900 kJ/m3. Pipe diameter, fittings and gas meter must be selected taking into account other gas appliances of the consumer. A pipe with a minimum connecting diameter of 1/2“ must be connected to the boiler, but preferably with a nominal diameter of 3/4“.

Size 25 KTV (KOV) - P is designed to operate on liquefied gas (propane), with a calorific value of 12.3 to 13.0 kWh/kg.

Due to the fact that the operation of the boiler with the use of cylinders is problematic, primarily from the point of view of ensuring a sufficient number of them, as well as their further use, the simultaneous use of a gas tank near the heated object and its filling by an authorized organization is envisaged.

Calculations required dimensions supply of propane from the gas tank to the boiler unit or other gas appliances are part of the project and delivery of the gas tank. With the help of a gas pressure reducing valve, it is necessary to ensure the nominal gas pressure in front of the boiler is 3.0 kPa.

Air supply and removal of combustion products

Air is supplied and exhaust products of combustion are carried out through an external coaxial pipeline? 100 mm. Equivalent length of the pipeline (numerically equal to the sum running meters straight pipe and number of 90° elbows) should be no more than 9 m. If the equivalent length of the pipeline is more than 3 m, the throttle disc must be removed from the fan outlet.

Horizontal sections of the pipeline must be installed with a slope of at least 1.5% towards the outlet flue gases so that condensate flows out of the pipeline. Condensate drains are used in vertical sections.

The outlet of the pipeline must be located:

At a height of at least 2 m from the foundation of the building in places visited by people and at least 0.4 m - in places not visited by people;

At a distance of at least 0.5 m horizontally from windows, permanently open ventilation grills and doors;

Above the upper border of windows, bars or doors;

In the area under awnings, balconies and roof edges.

Minimum distance between two adjacent pipe outlets:

Horizontally - 1 m;
- vertically - 2 m.

The direction of the pipe exit should be oriented so that the combustion products go out into the open space.

The horizontal distance from the end of the outlet of the pipeline on one facade to the other, with the opposite placement of outlets, should be:

2 m if there are no windows or bars on one facade;

1 m if both facades are without windows or bars;

4 m if both facades have windows or bars (or if there are adjacent exits on the same facade).

In the niche of the facade of the building, the distance between the axis of the pipeline outlet and the adjacent plane of the facade should be:

2 m if there are windows or bars on the facade;
- 0.5 m - if they are absent.

All distances are given from the outer border of the window (grille) or door to the axis of the pipeline. In the space under the canopy (balcony), the pipe head must be at a distance of at least the radius of the circle.

With a vertical exit of pipelines to the roof, their heads should be placed at a distance of at least 0.4 m horizontally and at a height of at least 0.4 m from the roof surface, taking into account its shape.

The chimney outlet must not be placed in an explosive area, in internal parts buildings or structures, tunnels or underpasses, in enclosed spaces.

A hole in the wall for the passage of a coaxial pipeline is made with a certain gap (from 10 to 15 mm). Upon completion of installation, the gap is insulated with non-combustible materials ( polyurethane foam, gypsum, plaster).

Electrical connection of the gas boiler Proterm Panther

The Proterm Panther boiler must be connected to the mains through a socket with a grounding contact, which eliminates the zero-phase connection error. The distance from the boiler to the socket must be within the length of the boiler power cord (1m).

The boiler must be connected to a protective conductor (ground). The ground conductor must be accessible for inspection and resistance testing.

For electrical connection it is not allowed to use various tees, extensions, etc. The boiler is protected against overload and short circuit by fuses P1 -T80 mA/250V, P2 - T 1.6 A/250V installed in the control panel. Before working on the electrical equipment of the boiler, it is necessary to disconnect the boiler from the mains by disconnecting the electrical plug from the socket.

To control the boiler from a room regulator, use a regulator with a potential-free output (except for the mains voltage, it is not allowed to supply any other voltage to the boiler). Connect the room regulator to the unit with a flexible two-wire cable with a cross section of 0.5 to 1.5 mm2. Exit the cable from the boiler through a plastic cable gland.

The terminal block for connecting the room regulator and the external sensor is located at the bottom, inside the boiler and is accessible after removing the outer cover and turning the control panel. Before connecting, the jumper must be removed from the terminal block. The minimum load on the output contacts of the regulator is 24 V / 0.1A.

The outside temperature sensor should be connected with a two-wire copper conductor with a cross section of 0.75 mm2. Wiring resistance should be no more than 10 ohms, the maximum length is 30 m.

The circuits for connecting the outside temperature sensor and the room thermostat must not be laid together with the mains voltage circuits.

Commissioning of the Protherm Panther boiler:

Remove the screw securing the cover to the bottom of the boiler;

Tilt the cover down (towards you) and lift it off the pins at the top of the camera.

Make sure the gas supply is closed.

Loosen the cap on the automatic air separator located on the pump.

Connect the boiler to electrical network.

Turn the power switch to position “I”. The display will show code F0, the pump will run for approximately 1 minute.

Press the Bar/Mode button. The display will show 0.0 (pressure value) and the LED will light up.

The pressure value is displayed for about 25 seconds. The display then returns to its original position. The pressure value can be displayed again by pressing the Bar/Mode button.

Fill the system with water, the pressure should be between 1.2 and 2 bar.

Carefully bleed all heaters (water flow should be continuous, without air bubbles).

Leave the cap on the air separator loosened during boiler operation.

Open the DHW taps to remove air from the DHW circuit;

Check that the pressure shown on the display is in the range of 1.2 - 2 bar, top up if necessary.

Starting the boiler Proterm Panther

Before starting the boiler check:

The main gas supply valve is open,
- gas cock open at the entrance
- closing valves (water, heating) at the outlet are open,
- the unit is connected to the mains.

To start the Protherm Panther boiler, do the following:

Switch the power switch to position “I”;

Set the extract air temperature to 85 °C and turn off the equithermal control (E-).

Check the condition of the room regulator (it must be closed);

Slowly raise the temperature in the heating system to the maximum (all radiators must be with open valves). The air in the water of the heating system is gradually removed through an automatic air separator. There must be no air at the highest point of the system and in the radiators;

Make up the system to a pressure of 1.2 bar;

Switch on the boiler again and heat the system up to the maximum temperature;

Turn off the boiler, if necessary, remove the air and re-feed the system with water;

Make sure that after the heating system has cooled down, the pressure gauge shows at least 1.2 bar;

If the pressure in the heating system in the heated state is higher by. 0.5 bar than when cold, check the setting expansion tank regarding the system.

Protective functions of the boiler Proterm Panther

The boiler is equipped with a frost protection function. When the temperature drops below 10 °C, the pump will automatically turn on. When the temperature drops below 8 °C, the machine will fire up and work until the temperature rises by 25 °C. In case of freezing (the temperature of the RH is below 3 °C), the start of the boiler is blocked.

The pump switches on automatically for a short time if it has not been switched on for 24 hours. This provides protection against blocking due to deposits during a long shutdown. The pump runs continuously when the temperature rises above 85°C (overheating protection).

When the pressure drops, the LED flashes, when the pressure drops further, the unit goes out (protection against water loss - alarm F0). When the pressure rises, work automatically resumes.

The protective functions are activated only when the boiler is connected to the mains voltage (the electric cord is in the socket and the mains switch is in the on (I) position.

If the boiler has been disconnected from the mains voltage for a long time (a month or more), it is recommended to start it periodically (at least once a month). The boiler is equipped with a safety valve. When discharging heating water from the valve, turn off the boiler and disconnect it from the mains voltage.

Boiler adjustment Protherm Panther

When the boiler is operating without a room regulator, it maintains the temperature set on the display.

Adjustment operations:

– select the equithermal regulation mode – select the heating curve and set the symbol E-;

– select the equithermal regulation mode – in the option of parallel movement, put the symbol P-;

– select the EXH temperature mode and adjust it;

– the room regulator must be switched off, a jumper must be installed between the terminals for its connection.

When the Proterm Panther boiler is operating with a room regulator, it maintains the temperature set on the display. In this case, the unit is switched off by the commands of the room thermostat installed inside the control room. This room should not have a thermostatic valve on the radiator.

During installation, the jumper is removed from the boiler terminals and the room thermostat is connected. When operating in equithermal mode, the temperature changes depending on the change in the outside air temperature.

An external air temperature sensor must be connected to the boiler. The sensor is installed on the coldest wall of the building (north or northwest) at a height of about 2.5 - 3 m. The sensor should not be located in the area of ​​ventilation emissions from windows or other ventilation devices
and exposed to direct sunlight.

Inlet gas pressure control:

Switch off the boiler.

Loosen the screw on the pressure measurement fitting of the gas valve;

Connect an appropriate pressure gauge;

Carry out a launch;

Check the inlet gas pressure, if it is below normal, check the tightness of the gas pipeline;

Turn off the unit and disconnect the pressure gauge, carefully tighten the screw on the measuring point and check its tightness.

Electric boiler Proterm The slope for heating is the most common model in Russia among all manufacturers on the domestic market. Good European assembly quality and reliability of components, a lot of positive feedback on electric Protherm boilers and reasonable prices contributed to their popularity among buyers, both in Russia and abroad.

To understand the advantages and disadvantages of the Slovak heating equipment, needs to be disassembled specifications and the device of wall-mounted electric boilers Proterm of the Skat series, the model range on the market, and connection features. We will also consider problems and malfunctions that may arise during the operation of the device, errors and methods for their elimination.

Model range of electric boilers Proterm Skat, type K (KR)

To date, the Slovak company Protherm is represented on the Russian market not only by its boilers, but also by eight models of electric boilers of the Skat K (KR) type, which differ in power consumption and connection to the electrical network. The country of origin of water heaters is Slovakia.

The company produces only single-circuit devices capable of heating a private house with a total area of ​​​​30 to 280 m2. Among them, both single-phase - with the ability to connect to a 220 V power supply, and three-phase - 380 Volts stand out.

Electric boiler Proterm: photo

The main difference between electric boilers of this model range is their nominal power, which can be 6 or 9 kW, 12, 14 or 18 kW, 24 and 28 kW. Depending on the model chosen, these are the units:

- low power: Skat 6K and 9K;
- medium power: Skat 12K, 14K and 18K;
- high power: Skat 21K, 24K and 28K.

The operation of the Proterm electric boiler is controlled using special buttons, made in the form of multidirectional arrows, on the front panel of the heating apparatus.

They can set the required water temperature in the heating system, as well as in a remote indirect heating boiler, which is purchased if necessary to obtain hot water for business needs. In addition, the button " Mode/Ok» can be enabled (customized) desired mode electric boiler operation:

- traditional mode for heating (25-85 ° С);
- "warm floor" mode (30-45 ° С);
- the mode of preparation of hot water in an indirect heating boiler (35-70 ° C).

The multifunctional LCD display informs about the temperature in the heating circuit and the boiler, as well as about problems and errors in the operation of the boiler in case of any malfunctions. Above the display there are lights that light up depending on the set operating mode of the device, changes in power consumption and insufficient water pressure in the system.

By default, all electric boilers"Protherm" are 3-phase, however, low-power models of 6 and 9 kW ("Skat 6K" and "Skat 9K") can be connected to a single-phase 220 V network. Medium power devices are designed for heating a house up to 180 m2, and high-power boilers - more than 20 kW can be installed in private houses or other premises with a total area of ​​​​up to 280-300 m2. We look at the table.

Brief instruction manual

Competent adjustment of Protherm gas boilers provides optimal temperature conditions in rooms of different purposes and areas. Among other things, the regulation of the automation of such equipment helps to increase the efficiency of the unit, and also makes its operation reliable and safe. Modern automation solves problems:

• opening and closing valves in the gas supply system;
• the process of starting the unit in automatic mode;
• installed or emergency shutdown of boiler equipment;
• adjustment of the flame level in the burner by means of a temperature sensor;
• display on the screen of indicators of air temperature, the level of heating of the coolant and other parameters.

Instructions for setting up a gas boiler:

• thermostat connection to temperature sensor, fixed in the room, and setting the required values ​​\u200b\u200ballows you to get a comfortable temperature regime for heating;
• installation of a thermostatic valve on the supply pipes before heating radiators helps to change the cross-sectional area of ​​​​the pipe and easily carry out the process of controlling the temperature of the heat carrier;
• the first start of the system at the limiting temperature allows the used coolant to freely enter the tank, which contributes to its maximum filling;
• the increase in efficiency is facilitated by the timely removal of scale and soot, as well as the control of the absence of air in the system and the installation of a draft limiter;
• regulation of pressure indicators is carried out using special valve regulators, and in order to increase the pressure, a circulation pump is installed;
• the decrease in the power of the boiler burner is carried out automatically through the service menu, and the power is adjusted to increase by installing additional radiators or replacing existing ones with the most powerful models;
• many units are characterized by full performance at a pressure of 1.5 atm., And normally this value is 0.3 atm. lower than the indicators in the heating system;
• a slight decrease in the pressure level in the unit is restored during a standard restart;
• automatic selection of the operating mode of the gas boiler helps maintain the desired temperature level even with a long absence of consumers in the room.

The process of first turning on the boiler is accompanied by its short and energetic operation after the unit is fully connected to the heating system, which makes it easy to check the correct installation of the boiler equipment and the full functioning of the heating.

Common errors and malfunctions
