Agree that a comfortable temperature is the main guarantee of comfort. Therefore, installing a Protherm gas boiler becomes the key to the complete improvement of an apartment or house. But how to do this correctly and is it possible to do it on your own?

In this article we will talk in detail about installation features boilers, about the nuances and connection diagrams of popular brand models. Only if the standards and requirements for installation are observed, the brand’s gas equipment will serve for many years without interruption, providing heat to every home.

Features of installation of Protherm gas equipment

Installation of Proterm gas boilers, like installation of any heating equipment, has its own characteristics. Depending on the type of boiler, the consumer will have to take into account some nuances that affect the safety of operation and energy efficiency of the equipment.

General requirements for boiler installation

When installing Protherm wall-mounted gas boilers, the minimum permissible distance between the boiler, ceiling and floor must be observed. When hanging the boiler, there should be at least 50 cm to the ceiling, and 80 cm to the floor.

If the wall on which the boiler is installed is made of flammable materials, it must be additionally equipped with a metal sheet with a thickness of at least 3 mm.

You should first pay attention to the wiring. The cable from which the Proterm boiler will be powered must be stretched without bends or creases. Please note that the wiring will only ensure the operation of gas equipment; you cannot connect other equipment to it. Provide boiler grounding.

The diagram shows a standard grounding diagram for a gas boiler. The grounding circuit can be arranged on your own

After unpacking, flush the pipes to remove any dust from all cavities before installation. Dirt can clog the Protherm boiler system, so pre-cleaning is mandatory.

If the choice falls on a heavy floor model, it is recommended to make a screed or lay concrete slabs at the installation site. It is important that the finished platform is leveled strictly. We have provided more technical standards and requirements for the installation of floor-standing boilers in our other article.

If the model requires connection to a chimney, be sure to check the draft before connecting to the system. Additionally, it is worth fully inspecting the permeability of the chimney and cleaning its shaft.

Gas units produced by a Slovak company differ in type of installation and power:

1. Wall boilers They have less power, but are significantly cheaper. At the same time, the characteristics of the equipment make it possible to fully heat a private house.
2. Floor standing gas boilers Protherm have greater productivity, are more expensive, and take up significantly more space during installation. A separate foundation may need to be poured prior to installation.Therefore, the models are less popular among households, but are still in demand among owners of large houses.

Below we consider in more detail the popular series and models of gas boilers.

Lines of wall-mounted gas boilers of the brand

Due to their attractive price and relative compactness, wall-mounted boilers are in great demand. Protherm produces several lines of equipment to create an efficient heating system in a private house or apartment in a multi-storey building.

In the offices of official representatives, you can get acquainted with the plant’s product lines in a comfortable environment, look at the technical specifications and, if necessary, receive professional advice

Three lines are in demand on the domestic market.

1. Panther Series includes six productive models with a power of 12-35 kW labeled KTV, KOV and KTO. A number of KTVs are equipped with a system for forced removal of combustion products, so they are suitable for rooms without a chimney. Models of the KOV series are connected to a chimney with a natural outlet.
2. Line of boilers "Lynx" is represented by three models with a power of 24 and 28 kW with a system of forced removal of combustion products.
3. Double-circuit boilers "Gepard" with a power of 23 kW include the 23 MOV and 23 MTV models. The modifications differ in the removal of combustion products: in 23 MOV it occurs naturally, in 23 MTV it is forced.

The unit must be selected based on its potential performance, heated area, and installation requirements.

Series of floor-standing gas boilers Protherm

Products for floor mounting have serious power, so they are used for heating large rooms with a high level of heat loss.

Three popular lines of Proterm equipment cope well with the assigned tasks and have their own characteristics that should be taken into account during installation.

Boilers "Bear" and "Grizzly"

Floor-standing boilers with a cast iron heating circuit differ in their characteristics.

Floor-standing Proterm models are more suitable for heating industrial premises. However, this equipment can also be installed at home.

Each of the models has its own functional features.

1. The KLZ model range is characterized by an efficiency of 90-92% and a power of 20-50 kW. The devices are equipped with a built-in 90 liter boiler and an electric ignition system.
2. Single-circuit models of the KLOM series have an efficiency of about 92% and provide for the connection of a capacitance indirect heating.
3. The PLO line, like the KLOM, allows you to additionally integrate a boiler into the system. The power of the equipment is 20-60 kW, allowing you to heat the coolant up to 90 degrees.
4. The TLO series equipment combines single-circuit models with a power of 20-50 kW, equipped with a single-stage atmospheric burner. The exhaust of flue gases is natural.

Another direction for industrial use, which differs from the “Bear” in its greater power (65-150 kW) and the type of fuel consumed. The equipment runs exclusively on natural fuel. The boilers are equipped with a stepped burner, a natural smoke removal system and electric ignition.>

Floor-standing boilers "Bison"

Industrial floor-standing boilers with 2-pass reversible flame flue with stunning outputs ranging from 70 to 3500 kW can run on both natural gas and liquid fuel. With a fairly restrained flow rate, the devices have an efficiency of approximately 92%.

But before you connect the Protherm floor-standing gas boiler of the “Bison” series, you should take care of the arrangement forced circulation systems coolant.

A detailed diagram of the forced circulation of the coolant is clearly shown in the schematic drawing. The drawing shows the need to install a circulation pump

Connecting the equipment is quite complicated, but the increased power completely justifies all the costs of installing and servicing the unit.

Schemes and stages of connecting a wall-mounted boiler

Installation of gas equipment must be carried out by a specialist. However, the connection diagram for a Protherm wall-mounted gas boiler should be accessible and understandable to the average user. Since the “Panther” series is the most popular due to the fast heating of water using Aquafast technology and the ability to install equipment in a room without a chimney, let’s look at the intricacies of connecting boilers using the KTV series as an example.

Stage #1 - familiarization with the installation diagram

The first step is to carefully consider the design features of the model and the installation diagram. All this information is in the user manual supplied with the equipment.

The structure of the equipment itself is shown in the diagram below.

A detailed diagram of the Proterm wall-mounted boiler is provided in each instruction manual from the manufacturer

Before direct installation, it is necessary to carefully consider the layout of all pipes.

The installation diagram is discussed below.

Such a boiler can become the center of an entire individual heating and water heating system, the approximate wiring of which is shown in this diagram

Stage #2 - hanging equipment on the wall

Once the package has been supplied and a safe installation location has been selected, a mounting template can be used to determine where to drill the holes.

But first you need to make sure that the selected wall can withstand the load and weight of the product, and the purchased fasteners can be used on a specific surface material.

The principle of hanging a gas boiler is shown in the diagram.

Proterm gas boilers are hung on the wall in the standard way, like other wall-mounted gas-using models

Stage #3 - installation work

Basic installation work takes place in several steps.

1. The crimp threaded connection from the kit is installed on the gas pipeline.
2. Then it is checked whether the volume of the built-in expansion tank is sufficient. If its capacity is insufficient, the structure should be equipped with an additional expansion tank, installing it on the return line of the heating system, as close as possible to the boiler.
3. If there is a need to install an additional tank, it should also be installed at the boiler outlet. check valve.
4. All supply lines must be thoroughly flushed before installation.
5. The cold water pipeline is equipped with a shut-off valve and a check valve.

After this, you can check the gas meter: this unit must be designed to pass the expected gas flow. If the meter meets the specified characteristics, you can connect the gas system to the supply or return line of the heating system. This process is clearly shown in the diagram.

Connecting the gas system to the boiler requires special care and compliance with all safety standards.These actions must be performed by a gas service representative with a special permit

The hot and cold water connections, as well as the hot water tank and drainage hose, are made according to the following standards.

Connecting hot and cold water is shown in the diagram in the instructions for the Protherm boiler (diagram 1). A visual connection of the drainage hose is shown in Figure 2

Next, connect the combustion product exhaust system. The KTV boiler, on the example of which we are considering the installation process, is equipped with a closed combustion chamber. The exhaust and intake of air in it occurs forcibly through a coaxial system, for which purpose the design includes a turbo chamber with a built-in fan.

The manufacturer offers several ways installation of a coaxial chimney, from which you can choose the most suitable option. The main thing is to ensure that the condensate flows outside the system or to specially installed condensate collectors.

Stage #4 - connecting the boiler to the power supply

The supply line for connecting the boiler must have stabilizer and a circuit breaker.

Electrical installation of a gas boiler takes place in the usual way:

1. The connecting wires are routed through the cable entry and shortened to an acceptable length.
2. A corresponding plug is screwed onto the cable, freed from insulation and braiding.
3. When all the wires are firmly inserted into the plug terminals, the plug itself is installed in the corresponding socket on the board.
4. Finally, all cables must be secured with special clamps.

Any skilled craftsman can handle such manipulations.However, installation work carried out by a certified specialist is safer and meets the manufacturer's requirements.

Subtleties of setting up and operating the boiler

To create an optimally comfortable microclimate in the house, any boiler from Proterm needs to be configured. Automation of the models allows you to completely adapt the operation of the device to your needs and preferences and independently regulate the temperature in each room.

Thus, the “electronic brain” of the boiler makes it possible:

• diagnose faults, store the last 10 errors in memory;
• regulate the flame level in the burner thanks to a temperature sensor;
• autonomously start the heating system;
• monitor temperature indicators;
• completely turn off the operation of the boiler thanks to preliminary settings in an emergency or if necessary, etc.

The electronic system is configured according to the factory instructions supplied with the kit. For safety reasons during operation, the setup should be entrusted to a specialist.

Protherm takes responsibility for the maintenance of its equipment and the qualifications of its technicians. Therefore, specialists often undergo official certification from the manufacturer

To increase the efficiency of a gas boiler, it is worth familiarizing yourself with a number of subtleties of its operation.

There are certain nuances, the understanding of which will be useful to every owner of Protherm boilers:

1. To more accurately regulate the temperature of the coolant, you can connect the room thermostat to the gas boiler.
2. A thermostat connected to a room temperature sensor will also make it easy to set the desired temperature in a specific room.
3. If the pressure in the Protherm unit has dropped slightly, its level can be restored by restarting the boiler regularly.
4. In order to fill the coolant reservoir as much as possible, the first start-up of the system must be performed with the maximum possible temperature set.
5. If the efficiency of the boiler has dropped, it is necessary to exclude the presence of soot and scale, and diagnose the system for the absence of air pockets. It would also be useful to install a draft limiter. We recommend checking out the best ways to increase efficiency.
6. If there is persistently insufficient pressure in the heating system, it is necessary to installation of a circulation pump.

These subtleties will allow you to optimally configure the operation of complex equipment.
