Mora moravia gas boiler permit. Mora Top is a well-known brand of boilers from the Czech Republic. Malfunctions during the operation of Mora boilers

18.10.2019

Mora Top s.r.o. became famous all over the world after the Mora Moravia group of companies acquired it as a subsidiary. However, even before this transaction, products under the Mora trademark were supplied to the market in volumes of hundreds of thousands of copies.

By the way, the model called Meteor became a boiler, which was first produced abroad on the basis of a license agreement. Early 20th century Soviet leadership located a production facility in Petrograd.

Today Mora Top is an independent enterprise that specializes in the production of modern heating equipment. The company's production capacity enables it to supply about 100,000 water heaters and about 50,000 boilers to the market, which indicates the serious scale of the business. And the quality and reliability of products is confirmed by the fact that a huge percentage of finished equipment is exported to European countries and the CIS countries, where it is especially popular.

The Mora gas boiler is a harmonious combination of excellent performance, including high build quality, undeniable practicality and decent performance. These main advantages contribute to a stable growth in demand for the products of the Czech brand.

Mora boilers are ideal for use in country houses and city apartments. They have compact dimensions, allowing you to install the unit in any convenient place. In addition, their efficiency is quite high and ranges from 90 to 94%, depending on the model. At the same time, each unit of products supplied to the market under the Mora trademark is fully certified in accordance with European safety and quality requirements. The manufacturing company carefully takes care of such parameters as durability and excellent efficiency of equipment.

What boilers are there in the Mora Top range?

The Mora Top boiler, depending on the model, can operate on liquefied gas or diesel fuel. However, the manufacturer divides the entire range of products offered into two main classes on a different basis - wall and floor units. Some models in the Top range are equipped with additional equipment, such as a built-in storage that allows the boiler to be used for both heating and hot water, which is very convenient.

Allocate equipment with an open and closed combustion chamber. Models of the first type can only be installed in rooms with good ventilation, since the fence fresh air carried out directly in the place where the unit is located. A closed chamber implies a more complex design of the boiler, but at the same time more comfortable operation of the equipment. In such models, forced draft systems are installed that pump air inside the system through special built-in fans.

The main purpose of wall structures trademark Mora is a high-quality heating of small houses and apartments, the area of which does not exceed 350 square meters. Designs that are mounted on the wall are compact. They have a built-in heat exchanger made of high quality copper, which is not afraid of rust. This design feature makes it more wear-resistant and durable, which is very important in Russian conditions operation.

Mora Top Meteor is one of the most common series of wall-mounted boilers, which will delight you with affordability and unpretentiousness during operation. At the same time, none of the Meteor variations is inferior in functionality to more expensive units.

Mora Top Meteor Plus the lineup, including improved modifications popular models meteor. Boilers of this series are equipped with automation, which can be configured individually for a specific user. At the same time, the presence of an automated control unit makes the operation of heating equipment noticeably more reliable.

Mora Top Sirius is a line represented by the most “charged” and high-performance units, which provide a maximum of additional options, such as automatic boiler power control. Due to innovations, the engineers of the Czech company managed to create a device with high efficiency and low fuel consumption.

Separately, it is worth mentioning the Sirius models, the main distinctive feature which is the simplicity and unpretentiousness of the design. In addition, these boilers are very economical and easy to install.

Floor models of boilers of the Mora trademark of the Top series are represented by high-performance and amazingly hardy designs that easily withstand the aggressive climate of some northern regions of Russia. These units have cast iron heat exchangers, which are not afraid of sudden changes in temperature and rust. A considerable advantage of Mora floor-standing boilers is that they can withstand voltage drops without any problems. This is especially true in remote areas of our country.

An additional plus of the Czech brand equipment is almost silent operation.

The manufacturing company supplies the market with the following floor heating boilers:

Mora Top Classic is the best choice for small houses with poor thermal insulation. When comparing the price and quality of this equipment, we can conclude that the Classic model is the most attractive offer on the market.
Mora Top G - boilers designed for regions that are characterized by power outages. In addition, G-type models can easily cope with low system gas pressures down to 40 mbar.
Mora Top E - gas burner equipment, equipped with automatic electric ignition and a modern system that controls the temperature of the coolant.
Models type VL100-VL 750 are first class equipment equipped with forced draft burner. In structures of this type, an additional ventilation system is installed, which affects the level of noise emitted by the equipment during operation.

Mora boilers of the Top line are very reliable and easy-to-use gas burner equipment, for which the manufacturing company extends a one-year warranty. This once again confirms the excellent technical characteristics of the units.

Engineers of the Czech company took care of the safety of boiler users by equipping them with modern systems and fuses that prevent many problems, such as overheating of the coolant, pressure drop in the system, etc. With the correct installation of equipment and with careful operation, the user can significantly delay the moment of the first breakdown, which can occur decades later. This is one of their main advantages.

Speaking about the boilers of this brand, it is worth mentioning their main advantages:

High performance with low gas consumption;
Affordable price, both for the equipment itself and for components;
Adaptability to work in difficult climatic conditions;
Ease of boiler control, which greatly facilitates daily operation.

Wall-mounted gas boiler Mora

Gas, flow, heat-conducting boilers Mora, running on natural gas (or propane), are designed to heat rooms with heat losses up to 10, 18, 23, 32 or 35 kW, and combined boilers are also designed for heating utility water.

These boilers are wall-mounted. The removal of combustion products for some types of units is carried out outside through the chimney, for some - through the wall using a fan.

B - domestic water - outlet - G1/2”
C - gas - G3/4”
D - domestic water - supply - G1/2'
E - heating water - inlet - G3/4”

When installing the boiler, for its further safe and economical operation, it is necessary to have a professionally completed project for the whole heating system.

The Mora gas boiler can only be installed by an authorized service organization.

Only the type of gas that is indicated on the type plate of the product can be used for the operation of the unit.

The installed and mounted unit must not be moved to a new location.

The Mora boiler must be installed in such a way that the socket for its electrical connection is located in an accessible place. A phase wire must be connected to the left sleeve, a neutral wire to the right sleeve, and the upper pin to ground.

Failure to comply with this condition will cause the burner flame to go out after ignition.

The emergency thermostat, backflow fuse, fan and pressure switch are powered by 230 V. If it is necessary to interfere with the operation of these elements, it is imperative to remove the plug from the mains socket.

The gas boiler is installed in accordance with the projects for the heating system and for the gas supply of a residential building, utility facilities, industrial buildings etc.

If the heating system meets all the requirements for operation, safety and functionality, then the commissioning of the boiler can be carried out after submitting the following documents to the relevant gas supply organization: a project for the gas supply of the facility, an act on the readiness of the gas supply system, acts on the suitability of smoke and ventilation ducts.

Installing a Mora gas boiler on a wall

The device is designed for mounting on a wall made of non-combustible material.

The installation of the Mora 5118 boiler can only be carried out by an authorized service organization that has a permit (license) to carry out these works.

The boiler can be installed in bathrooms, washbasins and showers, but we recommend installing it above the bath at a distance of approximately 200 mm from the walls of the bath. The boiler must not be installed outdoors.

To comply with fire safety rules, it is necessary to observe a safe distance between the apparatus and combustible materials: 100 mm - from the front wall of the boiler, 50 mm - in other directions.

In order to have an accessible approach to the functional parts of the boiler during maintenance, repair or maintenance, we recommend observing the following dimensions: 500 mm - from the front wall, 500 mm - from above (minimum 200 mm must be kept to be able to remove the casing), 300 mm - from below.

There are no special requirements for floors or coverings.

The boiler is fastened to the wall with two screws or hung on brackets with two holes located on the frame of the boiler body at a distance of 280 mm from each other.

An important circumstance when placing is the height of the room.

It is necessary to pay attention to the fact that the vertical dimension from the end of the upper damper of the draft rectifier to the middle of the chimney in the wall is at least 500 mm.

Connection of boilers with a flue pipe

Mora boilers of the “turbo” version have a closed combustion chamber, they suck in air for burning fuel from the outside. During installation, there are no restrictions regarding the ventilation of the room.

The boiler can be installed using a set of connecting elements. The tubes included in the set of these fittings are made of stainless steel and can be installed on the connection panel during installation.

The device is equipped with a fan. The execution of the exhaust of combustion products and the air supply can be double (coaxial) or two-pipe (separate air supply and exhaust of combustion products).

Heating

The Mora 5118 boiler will start working when it receives a signal from the room thermostat to reduce the temperature in heated rooms.

The pump will accelerate and the gas fittings will open the flow of gas to the main burner. Heating water flows from the pump to the heat exchanger, where it is heated and then enters the heating system.

Temperature heating water registered by the heating water temperature sensor. Heating of heating water continues until the boiler is turned off when the desired temperature in the heated premises is reached.

Thus, the process is repeated as long as the boiler is connected to the mains. The heating water temperature is set to the maximum value.

Water heating

The process of heating domestic water is a priority over the process of heating water for the heating system.

The flow of water through the domestic water flow fuse will introduce the boiler into the process of heating domestic water when the 3-way valve changes the direction of heating water flow, and it will pass through the secondary heat exchanger, and from there back to the pump.

From the heated heating water in the secondary heat exchanger, in accordance with the temperature set by the User, domestic water is heated.

By changing the power of the burner, the electronics system maintains the temperature of the domestic water at the selected level.

After the end of the selection of warm utility water, the boiler will automatically switch to the heating process.

In the process of heating domestic water, the pressure of the gas supplied to the main burner changes so that the temperature of the domestic water corresponds to the set one, regardless of fluctuations in the flow of water under the influence of fluctuations in the inlet pressure, i.e., an increased flow of water will cause an increase in gas pressure, and vice versa.

Work safety

The following elements ensure the safe operation of the Mora gas boiler:

Electronic control and regulation unit - An electronic unit that provides and controls the operation of individual elements of the boiler (pump, thermostats, 3-way controlled valve, flow sensor, etc.).

Heating and domestic water flow sensors - will not allow ignition of the main burner in case of insufficient water flow.

Emergency thermostat - will close the gas supply to the boiler when the maximum allowable water temperature in the heat exchanger is exceeded.

Backdraft safety device - If clogging occurs chimneys(even partial), which will contribute to the entry (leakage) of combustion products into the room, the backdraft fuse will register an increase in the temperature of the surrounding space and cause the gas supply to the main burner to be closed.

The boiler can only be put back into operation after the fuse has cooled down, i.e. after approximately 10 minutes, by pressing the RESET button.

Pressure switch - If there is a clogging of the pipes for the removal of combustion products (even partial), or the combustion of fuel worsens (it will be below the established norm) due to a decrease in fan speed (voltage drop in the mains), or the fan does not work, then thanks to the pressure switch, switching on will not occur boiler so that combustion products do not accumulate in the closed combustion chamber.

The backdraft safety device or the pressure switch must always function during boiler operation and must not be affected by anything (eg change of position).

If the backdraft safety device or pressure switch trips again, contact an authorized service organization for troubleshooting and a functional test.

Preparation for operation

When preparing the Mora wall-mounted boiler for work, the following must be done:

Check the water pressure in the heating system,
- open the heating water (or utility water) inlets and outlets - (valves under the boiler),
- open the gas supply to the boiler.

The specialist of the service organization, when putting the boiler into operation, is obliged to:

Check pump mode - must be set to stage 3.

Start the boiler.

Carry out ignition control:

Turn on the boiler with the button control panels,
- after 5 seconds, the burner will ignite from a series of sparks - ignition lasts 5 seconds,
- repeat ignition 5 times.

Check the functions of the ionization electrode - blow off the flame from the ionization electrode - after 3 seconds the burner should go out.

The electronic control of the boiler will automatically switch to ignition mode (another attempt to ignite the burner will follow).

If the burner does not ignite, the display will show fault code E2 - loss of flame. To ignite, press the RESET button on the control panel.

Carry out burner control:

Check the main burner, the flame should only be near the outlets,
- check the stability of the flame along the entire length of the burner plates.

Adjust the heating and initial power.

Malfunctions during the operation of Mora boilers

Error E0 - Temporary malfunction, possibly a malfunction of the control and regulation unit - Call a service specialist.

Error E1 - Lack of water (no water in the heating system or insufficient water flow) - Deair the heating system, radiators. Try several times to turn the boiler on and off or turn on domestic water (in combined boilers).

Error E2 - Switching off the boiler (for example, loss of flame control, turning off the back draft fuse) - In boilers with flue gas discharge into the chimney, check the patency of the combustion paths. Press the RESET button.

Error E3 - The heating water temperature sensor is open - Call a service specialist.

Error E4 - Domestic water temperature sensor is open - Call a service specialist.

Error E5 - Malfunction on the security module (automatic ignition, excess maximum temperature water) - In boilers with combustion products outlet through the wall, check the patency of the flue gases outlet or air supply pipes.

The device and internal design that Czech gas boilers Mora Top, allowed to create heating equipment new generation, optimally corresponding to European and domestic standards.

In the line of the manufacturer Mora, mounted and floor-standing units have found a place, differing in different technical specifications, principle of operation and performance.

Description and characteristics of attachments

Single-circuit and double-circuit wall-mounted Czech gas Mora boilers Top have three basic modifications:

The single-circuit and double-circuit gas wall-mounted heating boiler Mora Top has a built-in programmer, a block with which you can set the work program for several days in advance.

Overview of floor standing boilers Mora

Mora Top floor 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. Heat exchanger and internal organization are designed taking into account the use of this liquid as a heat carrier.

As practice shows, the Czech water-heating non-volatile floor flowing gas heating boiler Mora Top is optimal solution for heating country houses. The absence of complex automation, electricity-dependent units, high performance - all this distinguishes the equipment of this series.

Carrying out installation work

Mora gas appliances are thought out in such a way that the 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. The boilers are equipped with Mora equipment. As a result, automation, burner and other components provide stable and long-term operation.

Commissioning and adjustment of the boiler is carried out as follows:

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

Czech gas boilers Mora generally start up without difficulty, but there are exceptions, mainly related to violations of transportation or installation.

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

Why it is worth buying a Mora brand boiler

Mora's boilers have something that other manufacturers often miss - an understanding of the complexities and peculiarities of working in domestic conditions. A potential buyer is also attracted by the possibility of choosing a suitable model.

A huge model range is presented: from 15 to 750 kW. Can be selected completely automatic installation and a classic boiler without complex automation. Simple operating rules also ensure the popularity of the Czech Mora models.
