Main types of gas boilers Mora Top - characteristics and instructions

Radiator contamination

You can find out complete information on the selection, operation and maintenance of gas water heaters (instantaneous water heaters) from all manufacturers if you go.
In addition to specific information on the site, you can also study specific problems from other people on this topic who have already purchased a gas water heater or instantaneous water heater and thus avoid them. You will find a regularly updated list of such problems and their solutions.

The radiator is made up of metal plates with a small distance between them. Since they are exposed to the flame from the burner, soot accumulates between them over time.

Gas water heater radiator

This can be seen from the yellow color of the fire. The flame can be directed not in the upward direction, but to the side, thereby heating the casing. The water takes longer to heat up even when the column is running at full power, and black soot pours out from under the device.

For repairs, you should remove the column shell, disconnect the heat exchanger pipes and completely dismantle it, first covering the burner with a rag so that it does not become clogged. The most convenient way to clean the radiator is in the bathroom under running water. If necessary, it is left to limp in a container with chemicals. At the end, it is cleaned with a soft long bristled brush, dried and installed back.

Scale deposits in the heat exchanger

Mora heat exchangers are made of high-quality copper, 1 mm thick. The water heats up inside the tubes and scale accumulates on their walls. This leads to an increase in heating time and a decrease in pressure. The main sign of clogging of the heat exchanger pipes will be that water flows actively from the tap, but the pressure through the column is weaker.

To clean scale yourself, you should remove the casing from the water heater, drain the water and unscrew the union nuts from the heat exchanger outlets. After this, a special liquid for dissolving salts, which is sold at a hardware store, is poured into the tubes using a hose. Instead, you can use a solution with citric acid or vinegar. You will need to wait a few hours for complete cleaning.

For prevention, the heating temperature should be set to no more than 50 degrees. If the temperature is higher, scale deposits especially actively.

A little about the company

MORA-TOP began its 185-year history as a subsidiary of MORA MORAVIA AS. And only in 2003 it became independent. In the spring of next year, construction of the plant began in the Czech town of Unicov. The capacity occupied 5,000 square meters and was built in less than a year, so that in the spring of 2005 the world saw the first Mora instantaneous gas water heater produced at the new factory.

Today the company has a fully established technological chain for the production of equipment, including:

• Technology for processing copper and manufacturing heat exchangers, as well as stamping, degreasing stage, soldering and painting.
• Production of structural thermoelements.
• Assembly of finished products within the assembly line.
• Mandatory testing of devices.

Preventative repair work

For proper operation, the Mora water heater requires regular maintenance:

• From time to time it is necessary to replace the batteries. If they sit down, the spark continues to be produced, but its power is not enough. The standard size of the nutrients is R20 at 1.5 volts. The container with them is located at the bottom of the device.
• If you have hard and dirty water, you should clean and change the strainers on time. They are installed on the cold water inlet pipe. Failure to do this will result in a decrease in pressure over time.
• The igniter is clogged. In semi-automatic models with a wick, the jet becomes clogged with dust over time. You can clean it with a thin soft wire.

If after diagnostics you cannot find the cause of the malfunction, call a specialist.

This instruction manual in Russian is intended for the Mora-Top Meteor heating boiler; it describes the principle of operation and the main points of operating the device.

The manufacturer strongly recommends that you carefully study these instructions before turning on the heating boiler.

Wall models of gas equipment

Mora's single- and double-circuit wall-mounted gas boiler is represented by the following lines:

1. Mora Meteor - this modification is the only one that does not have a control board. All commands for heating temperature and hot water preparation are carried out by a non-volatile gas valve from the manufacturer Sit. It is equipped with a room thermostat with the ability to control the room temperature. The equipment can be: with an open chamber (exit to the chimney) or with a closed chamber (turbo exit), also with the possibility of hot water (double-circuit boilers) or only for heating with the possible connection of an indirect heating boiler (single-circuit). The power of the units varies from 18 to 24 kW, boilers are installed to heat rooms from 30 to 240 m² and prepare warm water 11 l/min and 14 l/min.
2. Mora Meteor Plus - this line includes boilers for heating areas also from 30 to 240 m² and heating liquids of 11 l/min and 14 l/min. However, these boilers are completely energy dependent and have the ability to separately regulate hot water supply and heating. The series includes single- and double-circuit modifications. The units have two options for functioning with exhaust gases: an open-type combustion chamber with a natural exit of exhaust gases into the chimney, a closed-type combustion chamber with a forced exit of gases into a coaxial chimney. Boilers intended only for heating can work in conjunction with an indirect heating boiler.
3. Mora Sirius is a series of boilers with weather-compensated control and an electronic room thermostat. Power characteristics are presented in three groups - 20 kW, 25 kW and 35 kW. There are two types of boilers: with an open combustion chamber (exit to the chimney) and closed (turbo exit), with the possibility of hot water supply and only for heating with the possible connection of an indirect heating boiler. The gas boiler Mora Top Sirius does not overuse gas. Electronic sensors accurately measure the temperature at the outlet of domestic water, and the control unit adjusts the gas flow in connection with the specified temperature and the speed of its measurement. When developing Mora Sirius, specialists paid attention to the use of innovative and high-quality elements, taking into account comments and requirements that came from users, customers, and technical experts.
4. The wall-mounted gas boiler Mora Titan is made only with an open combustion chamber for heating areas up to 140 m². This unit is a worthy alternative to floor-standing boilers from Russia with a power of up to 14 kW. It differs from domestic models in its lightness, compactness and optimal performance. There is the possibility of forced removal of combustion products using a turbo nozzle (for places with a problematic chimney or the absence of one).

Floor models

The Mora floor-standing gas boiler is presented in more than ten versions, the main difference of which is the type of burner and firebox used:

1. Atmospheric burner. Mounted in the ELITE line of boilers - the best, admittedly, models of heating equipment. The burner device is made of high quality steel and is characterized by a long service life. For more convenient use, it is possible to connect an indirect heating boiler (for hot water supply) and install temperature sensors. Thanks to their technical characteristics, Mora's energy-independent floor-standing boilers are a good solution for providing heat to a cottage or private home.
2. Pressurized burner. It is available in closed type units. There is an automatic ignition lock, two separate circuits. The primary heat exchanger is made of steel, the secondary one is made of copper. Gas is consumed very economically, this is not difficult to notice when changing fuel. Conversion to liquefied gas is possible when replacing the burner device.

An overview of different types of burners for boilers is presented here

To increase performance and thermal output, experts recommend using antifreeze. The heat exchanger and internal structure are designed taking into account the use of this liquid as a coolant.

The Mora Top gas boiler has proven its efficiency and reliability, therefore it is an excellent solution for equipping houses outside the city with heat and hot water. The design does not have complex automation or energy-dependent components. Characterized by high performance.

Common boiler malfunctions and repairs:

The flame in the burner goes out when the unit starts;

A lot of soot is formed;

Loud popping noises are heard when the equipment is operating;

The boiler does not turn on and does not respond to the reset button;

The pressure in the heating system constantly drops.

AIS company always strives for fruitful cooperation with its clients. Personal approach to each client, discounts, competently performed complex work, guarantees for work.

The structure and internal design of Czech gas boilers Mora Top made it possible to create a new generation of heating equipment that optimally complies with European and domestic standards.

The Mora manufacturer's line includes mounted and floor-mounted units, differing in different technical characteristics, operating principles and performance.

Floor-standing

Atmospheric floor-standing boilers MORA SA 40 G are recommended for heating facilities located in areas with unstable power supply. Classic series models are equipped with a stainless burner device that operates stably even with low gas parameters. They belong to the class of cast iron boilers and have proven themselves to be reliable, inexpensive and fairly economical heat generators.

Note! According to buyers, today in Russia they are the most common among similar devices. The burner device is simple and operationally reliable

Its advantage is silent operation and low energy consumption. The developers have provided the Mora boiler with maximum resistance to frequent pressure changes in the gas main, including modes with low gas inlet pressure

The burner device is simple and operationally reliable. Its advantage is silent operation and low energy consumption. The developers have provided the Mora boiler with maximum resistance to frequent pressure changes in the gas main, including modes with low gas inlet pressure.

The longevity of the device is ensured by the inclusion of a cast iron heat exchanger, which does not suffer from low-temperature corrosion, like steel, and does not burn out, like copper. The unit has a burner flame control function using a thermoelement that prevents gas leakage. The backdraft fuse works as part of the protection system and prevents flue gases from entering the room. Electronic regulation with a temperature limiter in the boiler controls the level of heating of the circulating water, and in the event of overheating in an emergency, it will send a signal to the shut-off valve to shut off the flow of gas into the boiler and take it out of operation.

Built-in reliability features

Reliability of units of this design is ensured by the following boiler functions:

• Protecting the secondary boiler from scale formation by applying a special agent to the heating surface.
• Preventing water from freezing in the internal circuit of the heater.
• Guaranteed operation of the pump and three-way valve without jamming.
• Boiler overheat protection. After the gas supply is stopped, the pump will continue to circulate until the medium cools down to an acceptable level.
• Stable operation of the unit at parameters in the electrical network of 160–250 V.

Note! When the circulation circuit is clogged, it is possible to provide movement in the primary boiler with a bypass line

Mora's main speaker lines

Gas water heaters are represented by a number of lines; we will consider the most popular of them, focusing on the characteristics of individual models.

VEGA MAX

VEGA MAX wall-mounted speakers replaced the old Mora devices 370, 371, 5502 and 5502. What is their main advantage: the connecting dimensions have not changed, so for those whose old column has already served its useful life, it will be easy to replace it with a new heater .

Suitable for both residential and non-residential premises with a thermal power of 17.3 kW. The consumption is 10 liters per 1 minute.

The heaters are equipped with high quality parts:

• Mertik water and gas fittings are made in Germany.
• Gas and ignition burners, heat exchanger made of Czech-made copper.

On a note! The copper pipes of the water heating apparatus have a large diameter of 18 mm and a thick wall of 1 mm.

These devices are equipped with automatic support for water temperature, without reference to its volume. There are options with both piezo ignition and electric ignition (from two R20 1.5 V batteries).

All gas appliances are highly safe, therefore, if there is no water flow, the gas valve will not operate and combustion products will not enter the room.

VEGA

The wall-mounted heater Mora Vega 10 and its “brothers” from the “Vega” line are positioned by the manufacturer as a completely new “star product”.

Interesting! The manufacturer’s website mysteriously states that Vega 10 is one of three bright stars (most likely, we are talking about three versions - 10, 13 and 16) that make up the summer-autumn triangle, and its brightness is many times greater than that of the Sun .

Minimum dimensions, combined with an ultra-modern design solution of the body, complemented by impeccable heater parameters, make these boilers one of the best among analogues that are on the market today.

Advantages of the line

• modest dimensions;
• ease of technical and user maintenance;
• full automatic operation;
• saving resources up to 10%;
• Efficiency up to 92%;
• the most economical way to provide hot water supply (DHW);
• smooth regulation of power modes;
• maintaining user-selected water temperature.

Device dimensions

• Height: for VEGA 10 - 59.2 cm, for 12 and 16 - 65.9 cm.
• Width: for VEGA 10 - 32 cm, for 13 and 16 - 40 cm.
• Depth: for VEGA 10 - 26.1 cm, in versions 13 and 16 - similar.

These are one of the most compact water heaters on the market, which also feature the smallest smoke channel diameter of only 11 cm.

Comfort level

• Flow-through heaters "Vega" 10, operating on gas, are equipped with German fittings, thanks to which the equipment starts up with a water flow of only 2.5 liters in 1 minute.
• This fittings provide for automatic maintenance of specified water temperature levels, which is especially important when the pressure (pressure) in the water supply network is unstable.

Economy parameters

Columns such as Vega 10 have some of the highest efficiency rates in the world - almost 92%. A small but quite effective heat exchanger warms up the incoming water 15% faster than any similar device from another brand.

Reliability

Design solutions and innovations ensure the maximum degree of reliability of all MORA TOP units:

• The moving parts of the device are fenced off from the water environment, so leaks in less dense joints are excluded. In other devices, leaks are possible, which necessitates replacing the entire gas-water unit, and this costs a lot of money - sometimes up to half the cost of the entire device.
• Inside the heat exchanger, there are turbulators in the tubes that push scale away from the walls of the unit, thereby accelerating heating and extending the operating life of the device.
• The diameter of the heat exchanger tubes, equal to 18 mm, not only prevents salts from settling on the walls, but also helps to cool the walls of the entire unit, eliminating overheating of the casing.

Security Settings

For safety reasons, the following points and design features are provided:

• Limiter of water overheating in the heat exchanger.
• Backdraft fuse for combustion products - it will prevent waste from entering the room if the chimney is clogged.
• A special flame fuse that ensures the serviceability of both burners (main and pilot).
• If there is no water flow, the device will not start the burner.

Additionally

Also, the units of the series are equipped with some technical solutions to facilitate operation:

• Piezoelectric ignition.
• The removal of waste combustion products through a chimney with a minimum neck diameter (gas) of only 11.5 cm.
• Possibility of using natural gas.

On a note! Units with the prefix “E” in their names, for example 10 E, are equipped with electric ignition.

Features of Mora TOP boilers

The device starts working by turning on the main burner, which is ignited by a piezo igniter depending on the speed of the circulating water, starting from 5.5 l/min. This indicator corresponds to the minimum power of the unit; the nominal one is achieved with a flow of 8 l/min. The unit is supplied without the By-pass function, so when starting the system, leave the valve on at least one radiator open. Adjustment of the technological process occurs in several modes, but always starts in the same way - by turning on the pump.

The main adjustment is made by a capillary thermostat in the network water range of 7–77 °C. More efficient regulation will be performed by a 220 V room thermostat, depending on the user-set indoor air temperature in the room. In this case, this thermostat is connected in series with the capillary one.

To prepare domestic hot water, the Mora TOP boiler can be connected to an indirect heating boiler using additional equipment. In this case, regulation occurs based on the demand received from the DHW thermostat of the boiler (ON/OFF). The capillary and room thermostat remain unconnected, the water temperature is regulated at 85 °C. If the capillary is installed in the “snowflake” position, the unit is in frost protection mode, and as soon as the temperature of the network water drops below, the heated internal circuit water will begin to circulate.

Control Panel

The control panel in boilers MORA 5118, 5120, 5121, 5122, 5124, 5125 is located in the lower part of the boiler behind the casing and will be accessible if the casing is lifted up approximately 100 mm.

ON/OFF button

When you press the “ON/OFF” button, the boiler turns on or off. When the boiler is turned on, the button will light up.

Heating water temperature adjustment knob

Designed to set the required heating water temperature in the range from 30 to 80°C. If the room thermostat is functioning, the heating water temperature is set to the maximum value.

“SUMMER-WINTER” mode switch (installed only on combination boilers)

When the switch is set to the “WINTER” position, the boiler is prepared for operation - heating heating water or domestic water. When the switch is set to the “SUMMER” position, the boiler is ready only for the process of heating domestic water. This mode is used mainly in the summer, when there is no need to heat the premises.

Thermometer

Shows the temperature of heating water leaving the boiler.

For boilers MORA 5119 and 5123

— the thermometer is installed on the boiler casing — the “ON/OFF” button and the heating water adjustment button are located on the left, under the boiler

Features of Mora Top geysers

We managed to win the sympathy of buyers thanks to a number of unique characteristics inherent in modern models:

• The presence of so-called “dry start” fuses. Without water, the burner simply will not light.
• Control of burner operation using a fuse. This is how any Mora device works, a gas water heater is no exception.
• Combustion products are prevented from entering the building thanks to a backdraft preventer. Water heaters can be installed inside any premises.

• Protection with a special limiter that controls the water temperature. Overheating of the device is practically excluded.
• From 115 mm - the diameter of the gas outlet neck of Mora geysers.
• The diameter of the tubes is up to 18 millimeters. Special turbulators are mounted on the internal surfaces. They prevent scale buildup.
• The heating rate is 15% higher compared to analogues due to the design of the heat exchanger.
• Automatically maintains temperature if the water speed changes while the Mora is running.
• Fittings from the German manufacturer Mertik. At a flow rate of 2.5 liters per minute or more, the column starts to turn on.

Note! The market price of most models does not exceed 16 thousand rubles.* The consumer properties of the Mora dispenser are higher compared to existing analogues

Advantages and disadvantages

Heating a home and hot water supply are two main issues that can be resolved by any buyer who decides to purchase gas water heaters. Cost-effectiveness and compact size are among the main positive aspects of the devices.

There are other characteristics that can attract buyers:

• The security system that Mora Top speakers are equipped with.
• High quality burner design. The igniter is completely protected from any contamination and damage.
• High efficiency, reaching 94% under any circumstances.
• Equipment works efficiently. Even pressure up to 0.2 atmospheres does not prevent the creation of such an effect in the Mora gas instantaneous water heater.
• Over time, heat exchangers do not leak. This is facilitated by the use of copper as one of the main materials.
• No noise when operating the Mora water heater.

Interesting! The disadvantage is that it is difficult to find parts for some models. Especially if they were released quite a long time ago. Mora gas water heaters are cheaper than existing analogues, but some buyers consider existing prices too high.

Technical characteristics of gas boilers "Mora TOP"

Installation

To install the boiler, as well as for its further safe and economical operation, it is necessary to have a professionally completed project for the entire heating system. The boiler can only be installed by a specialized service organization authorized by the manufacturer. To operate the boiler, only the type of gas indicated on the type plate of the product can be used. An installed and assembled boiler must not be moved to a new location. The boiler must be installed so that the socket for electrical connection of the boiler is located in an accessible place. If it is necessary to interfere with the operation of the boiler, be sure to remove the plug from the electrical outlet. The boiler is designed for mounting on a wall made of non-combustible material. There should be no objects made of flammable materials on the boiler itself or at a distance of 100 mm from it.

Decommissioning of the boiler

Long term

Long-term decommissioning of the boiler is carried out during maintenance and repair:

• move the ON/OFF button to the “OFF” position
• unplug the power cord from the socket
• close the gas and water supply taps

Short-term

• move the ON/OFF button to the “OFF” position
• leave the power cord plug in the socket
• Leave the gas and water supply taps open

Malfunctions of the Mora Top gas boiler

If there is any malfunction in the operation of the heating structure of this brand, the display will show the so-called “error code” and notify the owner.

You can see all possible error codes for Mora Top gas boilers here

The error may occur due to a malfunction of the pump, a closed switch, a lack of gas supply to the burner, problems with the safety module, etc. However, an indication on the display may not occur, but you will understand that there is a malfunction. In this case, analyze what exactly the problem is, find a description of it in the article (link above), read the possible solution to this problem and fix it.

Gas boilers from the Czech manufacturer Mora Top are adapted to domestic operating conditions, which many boilers from other manufacturers with similar technical characteristics cannot boast of. The buyer has the opportunity to choose a suitable heating model. The product range is huge: from 15 to 750 kW. You can choose a fully automatic installation and a classic boiler without built-in complex automation. Basic rules of use also underlie the popularity of Mora models.

Main types of gas boilers Mora TOP

The main modifications of gas units are divided according to the installation principle - wall-mounted and floor-mounted, according to the design of the firebox - open and closed, and according to the method of removing flue gases, there are three options.

Varieties of MORA-TOP TITAN:

• A device with an atmospheric burner and exhaust of flue gases into the chimney, version B11BS. The boiler will not start up without working pressure of the network water. This is the basic version, comes with a temperature limiter in the boiler, which prevents the water from overheating and turns off the gas supply.
• The atmospheric gas boiler "Mora" is equipped with a thermoelement, an expansion tank in the heating system and a reverse draft fuse that prevents gas leaks in the room.
• A unit with a “Comfort” burner reduces the temperature of the flue gases in the chimney by installing an additional boiler to generate thermal energy for the needs of hot water supply.

Important! The boiler has a function to prevent water from freezing in the heating circuit. When the water temperature in the network circuit drops below +5 °C, it will begin to heat it to protect the system from freezing

Review of Mora floor standing boilers

Mora Top floor-standing gas heating boilers are presented in more than ten modifications, the main difference of which is the type of burner and combustion chamber used. To increase performance and heat transfer, it is recommended to use antifreeze. The heat exchanger and internal structure are designed taking into account the use of this liquid as a coolant.

As practice shows, the Czech water-heating energy-independent floor-mounted instantaneous gas heating boiler Mora Top is the optimal solution for heating country houses. The absence of complex automation, electricity-dependent components, high productivity - all this distinguishes the equipment of this series.

Carrying out installation work

Mora gas appliances are designed in such a way that installation and maintenance of boilers are as simple and easy as possible. All volatile models have a self-diagnosis function. Information about all violations is displayed on the LCD display. The boilers are equipped with Mora equipment. As a result, automation, burner and other components ensure stable and long-term operation. Commissioning and adjustment of the boiler is carried out as follows:

• Volatile boilers are connected to the network. The self-diagnosis function starts automatically. The controller checks the presence of pressure in the heating system and gas pipeline. When deviations are found, a signal is issued in the form of a digital value. After troubleshooting, the boiler starts up.
• Non-volatile units do not have self-diagnosis functions, automatic flame ignition, etc. Therefore, before starting up and putting the equipment into operation, the company representative must ensure that all installation recommendations are followed. It is mandatory to install a water treatment system and a safety group; you may need to connect an expansion tank and a circulation pump.

Czech Mora gas boilers generally start up without any difficulties, but there are exceptions, mainly related to transportation or installation problems.

One of the common malfunctions of a double-circuit boiler is the failure of the thermocouple. After replacement, the functionality of the equipment is fully restored.

Installation of gas boilers Mora Top

Specialists thought through the design of the boiler and made it as simple as possible for installation and maintenance. All electrically dependent models have a built-in self-diagnosis option. Data about any malfunctions are displayed on the liquid crystal display. The boilers are equipped with Mora equipment. Therefore, the automation, burner and other components operate for a long time and stably.

Work on starting and setting up the boiler:

1. Electricity-dependent models are connected to the network. The self-diagnosis function automatically starts immediately. The sensor analyzes the presence of pressure in the heating system and gas pipeline. When malfunctions are detected, a signal is issued on the display in the form of an “error code”. After the operation is established, the boiler starts up.
2. In energy-independent boilers, there is no self-diagnosis option, auto-ignition of the flame, etc. Therefore, before starting the equipment, a company specialist must check that all recommendations regarding installation work are followed. It is necessary to install a water treatment system and a safety group; it may be necessary to connect an expansion tank and a circulation pump.

Mora gas boilers, as a rule, start up without difficulty, but there are still exceptions, and they are usually associated with improper installation or transportation.

A common malfunction of a 2-circuit boiler is a breakdown of the thermocouple. After replacing it, the functionality of the equipment is fully restored.
