Installation requirements for Lemax boilers

• The automation device includes a draught sensor – in case of insufficient intensity of combustion products removal, it switches off the burner. During installation, it is essential to create conditions to ensure a good draught. The manufacturer recommends to connect the boiler to a chimney made of sandwich pipes.
• The principle of operation of the boiler requires certain improvements – floor models often heat water for domestic needs rather weakly, which is a significant disadvantage of the equipment. Therefore, if there is a need to heat a large amount of water, it is better to choose a single-circuit unit and connect to it an indirect boiler, or opt for a hinged version of the boiler.
• Boiler piping – requires exact adherence to the manufacturer"s recommendations. The circulation pump is installed on the return of the heating system, just before the boiler.

How to service the boiler correctly

• Draught sensor – may trigger an emergency activation even with a good draught in the chimney. False alarms are caused by oxidized contacts of the device. After cleaning everything is back to normal. If the sensor fails, it is easy to replace.
• Igniter settings – the boiler may refuse to ignite due to insufficiently powerful combustion of the igniter burner. This malfunction can be eliminated by adjusting the flame output. The operating instructions contain information on how to do it yourself.
• Repair work – Lemax boilers for heating the house, is the best option, as repair and replacement of units can be done quickly. Virtually every specialized store has all the necessary assemblies.

Lemax gas floor standing boilers with steel heat exchanger

Five categories, each with a unique gradation in the power of the units, represent this class. As a result, you can select the heating appliance that best suits your requirements. The heating system’s pressure should not be higher than two atmospheres. Let’s take a closer look at the types of heaters that use steel heat exchangers:

• Lemax premium boilers;
• premium nova;
• patriot;
• gazovik;
• clever.

Lemax Premium steel boilers are separated into two categories. 7.5 to 60 kW for the first, and 70 to 100 kW for the second. The steel used to make the units is 2 mm thick. Similar to Konord boilers, the heat exchanger is shaped like a cylinder for increased efficiency.

Inhibiting compositions shield the inner surface of the heat exchanger from the buildup of salts and scale.

The heater has Italian automatic SIT technology and is energy-independent. Lemax heating boilers have smoke temperatures of at least 110 degrees Celsius. Water can only get up to 90 degrees. The nominal gas pressure at which the unit operates is 1.3 mPa.

The Lemax series premium nova heating boiler has undergone some enhancements. The thermostat and chimney turbo-charger connections are now made possible by the placement of the temperature regulator on the front of the housing. The heater also has a soft-start mechanism installed. This series’ units have powers ranging from 7.5 to 30 kW.

Patriot series boilers are unique in that their combustion chamber is closed. The unit does not require the installation of a complete chimney or a connection to the electrical grid. This parapet boiler uses a special pipe to draw air from the street for combustion (much like a chimney). There are outlets on both ends to connect to the heating system. The output power ranges from 6 to 20 kW. Every model has just one circuit.

Reviews indicate that carbon heaters are more dependable than infrared quartz heaters for dachas.

Lemax products

The business is currently prepared to provide a number of gas equipment models, including:

• Gas floor standing boilers Lemax single-circuit type.
• Two-circuit units.
• Water heating columns.

Many manufacturers sell their models and give thorough and trustworthy information about them. In addition to having excellent technical and functional qualities, these also have excellent handling, maintenance, and aesthetic qualities, as well as a contemporary approach to adding more features. Thus, natural gas-powered modern boilers are sophisticated devices that can heat any kind of building. Gas boilers Lemax are comparable to both domestic and foreign competitors in this regard.

Take note! TPP Lemax employs German and Italian technologies, which are regarded as the most cutting edge in the world, in the production of gas boilers. Thus, the excellent caliber of the goods

What does Lemax offer today in terms of heating boilers? In essence, there are two types of heat exchangers that are distinct from one another:

1. With a steel heat exchanger.
2. With cast iron.

The company manufactures boilers in three different series: leader, premium Nova, and premium.

Premium series gas boilers

Two millimeter thick steel sheet is used to make these units. This boiler series’ heat exchanger is coated with a unique mixture to stop corrosion. This includes both the surface layer of heat-insulating enamels and the customary inhibiting compositions. This kind of protection lengthens the heating boiler’s overall service life in addition to that of the heat exchanger.

Regarding the gadget itself, it functions in an independent manner. It doesn’t need any energy, electrical or otherwise, to operate. The model range offered by Lemax is split according to the unit’s power. In addition, there is a minimum power of 10 kW and a maximum power of 40 kW.

The gas boiler’s design is continuously being improved by the manufacturer. For instance, the Premium series is still enhanced with features like protection against overheating, a reduction in soot formation, and the absence of any negative moments due to draught interruption. The company’s experts have managed to ensure that the burner’s flame never goes out in the boilers. The high level of popularity of the Premium series boilers has been guaranteed by all of this.

Furthermore, this kind of heating unit is easy to use, dependable, safe, and convenient. The 3-year warranty for high-quality operation of this model is provided by the manufacturer.

Boilers series Premium Nova

With an enhanced automation system, the Premium series is essentially unchanged. This model depends on energy because of this. However, it is unquestionably advantageous when viewed from the perspective of simplicity of use.

For instance, you can configure the boiler’s operating mode to meet your specific needs, and the room’s temperature will affect the coolant’s temperature. This also holds true for the internal system pressure. The parameters that you manually set are regulated, controlled, and set by the automation itself. Furthermore, this is not just a huge benefit but also a convenience.

Leader series

The most costly and sophisticated kind of boilers is this Lemax model. It is composed of gray cast iron, which is renowned for its dependability, quality, and durability. The sheets used in the production have a thickness of 4 millimeters. Solutions-inhibitors are used to treat all internal surfaces of the unit, including the heat exchanger, to prevent corrosion. Because of this, these boilers have a minimum 25-year lifespan. Also, they offer a three-year warranty.

The company now provides energy-dependent and autonomous installations. Either way, you pay a fair price for a high-quality boiler. Automation only increases dependability, too. When it comes to power, there is a large range: 16 to 50 kilowatts. These boilers, incidentally, heat spaces that total at least 500 square meters.

Lemax gas boiler device

The automation unit, heat exchanger, and gas burner are the three primary parts of the Lemax heater.

Gas burner

The primary burner, wick igniter, and piezoelectric ignition make up this system. To light the igniter with the aid of the piezo element, the user must first press a designated button. Every time the automatics supply gas to the main burner, the igniter will light it.

Heat exchanger

The construction is tubular, and the spigots are linked to the heating system. The coolant is heated by the heat exchanger.

There are two heat exchangers in two-circuit boilers; the second one heats the tap water.

The way the scheme operates is as follows: when the hot water tap is opened, a unique 3-way valve in the boiler is activated, transferring heated coolant from the first heat exchanger to the second heat exchanger rather than the heating system.

Consequently, the heating system is not operating when the unit is operating in the water heater mode; this is something to consider when selecting a 2-circuit boiler.

Automation unit

A combined gas valve, which can be operated by an electronic controller or analog sensors (in non-volatile systems), is the primary component of automation. The latter is in charge of receiving and processing data from energy-dependent electronic sensors.

A conventional valve held open by a spring and a solenoid valve that is normally closed make up the combination valve. In order to ignite the igniter, the user must forcefully open the solenoid valve when starting the boiler. The unique thermo-sensitive element needs to be heated by the igniter, which requires holding the valve open for a short while.

The solenoid valve will then be held in the open position without the user’s intervention as this element starts to generate an electric current. The thermoelement will cool and cease to produce electricity if the igniter is blown, which will also cause the electromagnetic valve to close.

The signal from the temperature and draught sensors closes the second valve, which is spring-loaded. When heated, the liquid in non-volatile systems expands (it is in the capillary tube). It is a controller-controlled servo actuator in energy-dependent systems.

The boiler’s front panel houses the coolant’s temperature and pressure regulators.

Main types

"Lemax" boilers can be purchased as wall installations or as floor equipment. The heat exchanger in the first scenario may be constructed of cast iron or steel. When it comes to steel heat exchangers, these boilers function in closed systems and require a pressure of two atmospheres to operate. These kinds of devices are made for both private homes and tiny apartments. The heat exchanger is coated with an anti-corrosive material during the manufacturing process, which shields it from the damaging effects of mineral oils. If this protection didn’t exist, the product would need to be protected from salt solutions.

Floor and wall mounted

As of 2016, Lemax offered six different model lines of floor heating boilers in addition to one line of wall-mounted gas boilers.

Boiler "Lemax" PRIME series wall-mounted

• "Premium" 7,5-60

The sole range of wall-mounted models consists of a two-circuit boiler featuring a closed combustion chamber for a turbine. This makes it possible to install equipment in homes and apartments without a chimney or built-in ventilation system for gas appliances. Because the DHW circuit is built on an independent heat exchanger, it is more cost-effective but also more reliable.

Boilers with capacities of 19.5, 25.5, 30.3, and 34.6 kW are included in the line. control of an electronic microcontroller. spark ignition produced by the arrester. ideal choice for heating a 300 square meter apartment or home. м. To regulate the real heating, more remote temperature sensors within the space can be connected.

The focus with floor-standing boilers is on their energy independence—they don’t need to be connected to the electricity grid. Hydrothermal units are mostly utilized for control. Heat exchanger material, execution, and capacity (6-100 kW) determine the division by model series. Boilers of the "Leader" series come with cast-iron heat exchangers; the others are composed of steel.

It is optional to use a remote thermostat to regulate the room temperature in order to fine-tune the boiler. The equipment’s affordability and durability are guaranteed by the primary focus on design simplicity and dependability.

It’s important to comprehend the technical features and user experiences of boilers when it comes to heating and insulating your home. Lemax boilers are notable for their unique combination of performance, dependability, and efficiency. Modern technology and an easy-to-use design make Lemax boilers a dependable choice for homeowners’ heating requirements.

About the company

In 1992, Lemax was founded, or rather, it was already a group of companies. It started out as a trading company that supplied metal and heating equipment in bulk. It was decided to establish a distinct division for the assembly of gas boilers under its own brand name as early as the mid-1990s. This is another characteristic that sets Lemax apart. The creation and design of gas boilers with imported components is the primary emphasis. While this removes the need to coordinate its own technological production, it also results in a very diverse range of models without predetermined features and characteristics.

Lemax has frequently led the Russian market in terms of sales. The primary benefits of the products are their low cost, extensive network of retail locations and service centers, and, as of late, their primary use of foreign components.

History of the company

Like many well-known businesses and organizations with a global reputation, "Lemax" started out as a semi-basement, driven solely by the passion of its founders. It all started in Taganrog in 1992. A lot of things in the nation’s life were changing suddenly at the time. Manufacturing were shut down, economic ties were severed, and the nation’s leadership depended on private enterprise founded on its own land.

Lemax’s founders were fortunate to have assembled a top-notch group of professionals who not only saw through the challenging times but also elevated the business to the status of a whole factory. It’s safe to say that the objective has been met as of today. Furthermore, the company’s position in the market says a lot. This place is sturdy and stable, by the way.

One crucial point to remember in all of this is that gas boilers are being produced in an established manner using cutting-edge machinery.
