The boiler is designed to operate 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 the operation of the boiler must not exceed the ambient temperature by no more than 50 ° C.

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

Made of hardly flammable materials - at a distance of less than 100 mm from the surface;

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

Leave a free space of at least 1m in front of the boiler for maintenance work.

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

Standard parts can be used to create a coaxial flue for almost all installation options. The chimney length, type and number of sections must be agreed with the service organization.

The chimney must be laid so that flue gas condensate can be removed. For this, special sections are intended that are built into the chimney route.

The gas boiler Proterm Panther 25 KOV is designed to remove combustion products into the chimney with natural draft. The connection of the boiler to the chimney is carried out using a pipe with a diameter corresponding to the dimensions 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 exchangers, heat recovery, etc.).

Installation of a gas boiler Proterm Panther

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

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 water consumption 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 system pressure range is 1.2 - 2 bar.

The expansion tank of the boiler is designed for a heating system capacity of 95 liters. In larger systems, an additional membrane-type expansion vessel 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. The system must be thoroughly cleaned before installation.

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 at the inlet. If the hardness of the tap water is high, it is advisable to take appropriate measures to reduce it.

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

In the lower part of the boiler there is a hydraulic group, which is equipped with a safety-relief valve, a system filling (filling) valve 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.

It is recommended to connect the boiler to the heating system 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 valve.

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

Filling the Protherm Panther boiler and the 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 valve in the hydraulic group and at the same time monitor the increase in pressure on the boiler pressure gauge. The valve opens by turning counterclockwise, clockwise - it closes.

When the required pressure is reached, the filling valve must be carefully closed and checked whether the water pressure rises (the valve must be completely closed).

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

During repairs, unfavorable building layouts, etc., the boiler can be connected to the heating system, hot water supply 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. For connecting the boiler to a pipeline made of copper pipes you can use a special connecting set of shaped copper pipes with fittings.

Tube sizes:

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 - pipe 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 35,900 kJ / m3. The diameter of pipes, fittings and gas meter must be selected taking into account other gas appliances of the consumer. The boiler must be supplied with a pipe with a minimum connection diameter of 1/2 ", but preferably with a nominal diameter of 3/4".

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

Due to the fact that the operation of the boiler using cylinders is problematic, first of all, from the point of view of ensuring a sufficient number of them, as well as their further use, provides for the simultaneous use of a gas tank near the heated facility and its filling by an authorized organization.

Calculations of the required sizes of propane supply from the gas tank to the boiler unit or to other gas appliances are part of the project and delivery of the gas tank. Using the gas pressure reducing valve, it is necessary to ensure the nominal gas pressure upstream of the boiler 3.0 kPa.

Air supply and flue gas discharge

Is the air supply and the removal of combustion products carried out through the coaxial pipeline with an external one? 100 mm. Equivalent pipeline length (numerically equal to the sum running meters straight pipe and the number of elbows 90 °) should be no more than 9 m.When an equivalent pipe length is more than 3 m, the throttle washer 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 flue gas outlet so that condensate flows out of the pipeline. Condensate drainage devices are used in vertical sections.

The pipeline outlet should 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, constantly open ventilation grilles 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:

Horizontal - 1 m;
- vertically - 2 m.

The direction of the pipe outlet should be oriented so that the combustion products escape into the open space.

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

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

1 m, if both facades are without windows or gratings;

4 m, if both facades with windows or gratings (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 exit and the adjacent plane of the facade should be:

2 m, if the facade has windows or gratings;
- 0.5 m - if they are absent.

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

With a vertical outlet of pipelines to the roof, their heads should be located 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 should not be located in an explosive space, in the interior of a building or structure, in tunnels or underground passages, in closed spaces.

The hole in the wall for the passage of the coaxial pipeline is made with a certain gap (from 10 to 15 mm). At the end of the 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 plug socket with a grounding contact, which excludes a zero-phase connection error. The distance from the boiler to the socket must be within the length of the boiler power supply cord (1m).

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

It is not allowed to use various tees, extension cords, etc. for the electrical connection. 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 network 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-core cable with a cross-section of 0.5 to 1.5 mm2. Lead the cable out of the boiler through a plastic cable gland.

The terminal block for connecting a room regulator and an external sensor is located below, inside the boiler and is accessible after removing the outer cover and turning the control panel. Before connecting, remove the jumper from the terminal block. Minimum load output contacts of the regulator 24 V / 0.1 A.

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

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

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 the air from all heaters (water should flow out continuously, without air bubbles).

Leave the cap on the air separator loose while the boiler is running.

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

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

Boiler start-up Proterm Panther

Before starting up the boiler, check:

The main gas supply valve is open,
- the gas valve at the inlet is open,
- closing valves (water, heating) at the outlet are open,
- the unit is connected to the electrical network.

To start the Protherm Panther boiler, do the following:

Switch the mains switch to “I” position;

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

Check the state 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 heating water is gradually removed through the automatic air separator. There should be no air at the highest point of the system and in the radiators;

Make up the system up to a pressure of 1.2 bar;

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

Turn off the boiler, remove air if necessary and recharge the system with water;

Make sure that the pressure gauge shows at least 1.2 bar after cooling the heating system;

If the pressure in the heating system in a heated state is higher by. 0.5 bar than when cold, check the expansion tank setting in relation to 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 device will light up and will work until the temperature rises by 25 ° C. In the event of freezing (the extract air temperature is below 3 ° C), the boiler start-up is blocked.

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

When the pressure drops, the LED blinks, with a further decrease in pressure, the unit goes out (protection against water loss - alarm F0). When the pressure rises, operation will automatically resume.

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

If the boiler has been disconnected from the mains voltage for a long time (a month or more), it is recommended to start it up 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.

Regulation of the Protherm Panther boiler

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

Adjustment operations:

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

- select the RH temperature mode and adjust it;

- the room regulator must be turned 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 turned 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 outside air temperature sensor must be connected to the boiler. The sensor is installed on the coldest wall of a building (north or north-west) at a height of about 2.5 - 3 m. The sensor should not be located in the area of \u200b\u200bventilation emissions from windows or other ventilation devices
and be illuminated by direct sunlight.

Gas inlet pressure control:

Switch off the boiler.

Loosen the screw on the pressure measuring nipple of the gas valve;

Connect an appropriate pressure meter;

Carry out a launch;

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

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