Instructions and manual for Lemax Premium in Russian

Gas floor-standing boilers Lemax with a steel heat exchanger

This class is represented by five categories, each of which has its own gradation in terms of unit power. Thus, you can select the heating device to suit your needs as accurately as possible. The main thing is that the pressure in the heating system does not exceed 2 atmospheres. Let's look at the categories of heaters with a steel heat exchanger in more detail:

• Lemax premium boilers;
• premium nova;
• patriot;
• gas worker;
• clever.

Lemax premium steel boilers are divided into two groups. The first is from 7.5 to 60 kW, the second is from 70 to 100 kW. The units are made of steel 2 mm thick. For greater efficiency, the heat exchanger is made in the shape of a cylinder, just like Conord boilers.

The inner surface of the heat exchanger is protected with inhibitory compounds, which prevents the deposition of scale and salts.

The heater is non-volatile and equipped with Italian SIT automatic equipment. The smoke temperature in Lemax heating boilers is at least 110 degrees. Maximum water temperature 90 degrees. The unit operates at a nominal gas pressure of 1.3 MPa.

Some improvements have been made to the Lemax heating boiler of the premium nova series. The temperature regulator is now located on the front of the housing, and it is now possible to connect a thermostat and a turbocharger for the chimney. In addition, the heater is equipped with a soft start system. The power of the units in this series ranges from 7.5 to 30 kW.

The peculiarity of the Patriot series boilers is that they have a closed combustion chamber. The unit does not need to be connected to the electrical network and does not require the installation of a full chimney. This is a parapet boiler that takes combustion air from the street through a special pipe (similar to a chimney). At both ends there are outputs for connecting to the heating system. Power varies between 6-20 kW. All models are single-circuit.

According to reviews, infrared quartz heaters for summer cottages are less reliable than carbon ones.

Read this article about how to choose a heater for your room.

The gas worker series is a classic AOGV with a power from 6 to 29 kW. Accordingly, the device is volatile, the combustion chamber is of an open type, the operation is controlled by a thermocouple. Compared to models of other series, the gas line has a slightly lower efficiency (87% versus 90%). The heaters are equipped with draft, gas and water pressure sensors. Available only in single-circuit version.

The clever series heaters have the widest functionality. An indirect heating boiler, indoor and outdoor temperature sensors, a turbocharger for the chimney, and a control unit via the Internet can be connected to the boiler. Thermal power from 20 to 55 kW. Consumes 9 W of electricity per hour.

6.3. When installing the boiler to the heating network, it is necessary to lay a sheet of non-flammable material on the floor.

heat-insulating material, a sheet of iron on top, install the boiler on it.

6.4. Connections between the boiler and the heating system and the gas main must be threaded.

side ones, allowing, if necessary, to disconnect the boiler. If the boiler is installed to replace an old boiler, it is necessary to flush the pipelines and radiators of the heating system to remove rust deposits, scale and sediment. If these requirements are not met, deposit products (rust, sediment) are transferred to the boiler, which significantly complicates the circulation of the coolant and reduces the heat transfer of the boiler. In this case, claims regarding the temperature indicators of the coolant during boiler operation are not accepted by the manufacturer.

With increased heat consumption of the room (thickness of the external walls of the house, integrity of windows and doors, distribution of heating system pipes in attics, attics that are not insulated, exceeding its area or significantly exceeding the coolant capacity - the number of radiators, pipes) from the established standards, the temperature The temperature of the coolant may not reach 80 °C, which does not mean that the boiler is defective.

Gas wall-mounted boiler Lemax

The Lemax company produces only one line of prime-v wall heaters. Each device is equipped with SIT automation made in Italy. All models in this series are dual-circuit and can operate in heating systems with a pressure of up to 3 atmospheres.

Chimney of a parapet boiler.

The boilers are equipped with a closed combustion chamber, so they require the installation of a coaxial chimney. A fan is located above the combustion chamber. Turbocharging is needed to pump in air from the street and at the same time remove smoke outside. The maximum length of a coaxial chimney can be up to 5.5 m.

Solid fuel boiler Lemax

Solid fuel heaters are available in two configurations:

• solid fuel boiler – forward series;
• potbelly stove – series heat house and heat house-S.

According to reviews, the Lemax solid fuel heating boiler is designed to operate on coal. In this case, it is possible to use firewood and even natural gas as an alternative. In the latter case, you need to order a special burner. The peculiarity of this unit is the vertical loading of fuel, the hatch is located on top. Coal can be poured directly from the bucket.

The most economical heaters for an apartment are those that are equipped with good automation and thermostats.

About kerosene heaters for summer cottages is written here.

The TT boiler is available in three capacities (13.17 and 21 kW). Heats water up to 95 degrees, works in autonomous heating systems with pressure up to 0.2 MPa. The efficiency is quite low - only 75-80% for coal and 72-77% for wood.

Potbelly stoves are made from 4 mm steel. They come with a flat top and a basket for stones. The last option is used in doubles. The thermal power of both stoves is 10 kW. Weight 65 and 80 kg. Logs up to 60 cm long can be placed in the firebox. A potbelly stove can only be heated with wood.

Autonomous heating systems based on gas boilers are widespread in European countries.

In our country they are less popular, however, the situation is changing every year. Users are actively switching to heating using imported and domestic heating installations.

The choice of boilers is very wide, which makes it possible to choose the appropriate installation for any conditions or room size.

Let's consider floor-standing gas boilers produced by the domestic company Lemax.

Lemax floor-standing gas boilers

The Lemax company was founded in 1992 in Taganrog. Gas boilers produced by this company are assembled from imported components from leading European manufacturers.

Floor-standing boilers are non-volatile, operate on natural draft and do not need to be connected to the power supply, however, they have the ability to connect water heating units and turbo nozzles to create forced draft.

Lemax floor-standing boilers are presented in a large assortment; the model range has samples with a power from 6 to 100 kW, which allows you to heat apartments or large houses.

Device

Lemax floor-standing gas boilers have a heat exchanger in the form of a welded or cast iron container that forms a water jacket around the combustion chamber.

A gas burner is installed in its lower part, and under it there is a gas valve, control devices and connecting pipelines . The upper part of the heat exchanger has a passage for installing a chimney, which can be of a classic or coaxial design.

The connections for connecting the heating circuit for different models are located either on the sides or on the back of the boiler. There is also a hot water supply pipeline (for dual-circuit models).

The operation of the unit consists of the coolant entering the heat exchanger tank, heating and exiting independently under the influence of gravity - the density of the heated layers decreases somewhat, which helps to displace them by colder layers of liquid.

Self-circulation of the coolant is based on this effect. Hot water is heated in a copper coil installed inside the heat exchanger .

Smoke removal occurs under the influence of natural stove draft.

User manual

Operation of Lemax floor-standing gas boilers comes down to igniting the burner as needed and setting the desired temperature. All other operations - replenishing the volume of water in the heating circuit, installing a chimney, connecting a boiler - are performed without interfering with the boiler design.

To ignite the burner, turn the regulator to position 1, which means switching on the operating mode. Then you need to push it all the way and hold it while pressing the piezo ignition button.

When the pilot burner lights up, the button is released, but the regulator is held for about a minute.

Periodically it is necessary to clean the internal components of the boiler from carbon deposits and soot . You also need to monitor the condition of the heat exchanger, gas valve and other components of the unit.

Periodic maintenance should be performed by specialists from the service center. It is not recommended to do this work yourself, especially if the warranty period has not yet expired.
