Removal of combustion products in boilers of this type carried out into the chimney or using a fan (“Turbo”)

Boiler installation. Commissioning

When installing, commissioning and servicing the boiler, it is necessary to comply with certain rules established by state regulations and the requirements of the manufacturer. The user must carefully study the “Operation Manual”, “Warranty Card” and subsequently follow the rules set out in them.

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 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-flammable material. There should be no objects made of flammable materials on the boiler itself or at a distance of 100 mm from it.

Main Dimensions

MORA 5118, 5122

MORA 5120, 5121, 5124, 5125

MORA 5119, 5123

Commissioning

Commissioning of the boiler can only be carried out by a specialized service organization authorized by the manufacturer, which has a permit (license) from the relevant State Supervision Services.

When putting the boiler into operation, a specialist from an authorized service organization must do the following:

check the tightness of connections

adjust the boiler (if necessary)

check all boiler functions

familiarize the User with the rules for servicing and caring for the boiler

warn the User about the need to comply safe distances from the boiler to walls made of flammable material, and how to protect them

Description of the boiler operation

Heating - with connected room thermostat

The boiler will start working when it receives a signal from the room thermostat about a decrease in temperature in the heated rooms.
After receiving the signal, the pump accelerates and the gas fittings 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.
The heating water temperature is recorded by the heating water temperature sensor. Heating of heating water continues until the boiler is turned off when the desired (set) temperature in the heated rooms is reached.
Thus, the process is repeated as long as the boiler is connected to the electrical network.
The heating water temperature is set to the maximum value.

Heating - without room thermostat

The pump runs constantly. The operation of the boiler is controlled by a control and regulation unit in accordance with the temperature of the heating water, installed by the User control knob on the boiler panel

Heating of domestic water (combined boilers)

Heating of domestic water has priority over heating of heating water.
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 controlled valve changes the direction of movement of the heating water, and it passes through the secondary heat exchanger, and from there back to the pump. The heated heating water in the secondary heat exchanger heats up the service water.
After the end of the selection of warm domestic water, the boiler will automatically switch to the heating process.

Heating of domestic water (standard boilers)

Boilers intended for heating can also be used to heat domestic water in the MORA storage water heater. The storage water heater is connected to the heating system, domestic water is heated with warm water. heating water("WATER-WATER" system).
When installing the boiler together with storage water heater it is necessary to use a three-way valve with an internal microswitch, and room thermostat- these elements are supplied upon additional request.

Security systems

Safe operation of the boiler is ensured by the following elements:

Heating and utility water flow sensors- will not allow ignition of the main burner if there is insufficient water flow.

Emergency thermostat- closes the gas supply to the boiler if the maximum is exceeded permissible temperature water in the heat exchanger.

Backdraft fuse (boilers with combustion products discharged into the chimney)
If a blockage occurs chimneys(even partial), which will contribute to the entry (leakage) of combustion products into the room, then the backdraft fuse will register an increase in the temperature of the surrounding space and cause the gas supply to the main burner to close.
The boiler can be put back into operation by re-igniting the pilot burner only after the fuse has cooled down, i.e. after approximately 10 minutes.

Pressure switch (boilers with exhaust of combustion products "TURBO")
If the pipes for removing combustion products become clogged (even partially), or fuel combustion deteriorates (below the established norm) under the influence of a decrease in fan speed (voltage drop in the electrical network), or the fan does not work, then thanks to the pressure switch the boiler will not turn on, so that combustion products did not accumulate in the closed combustion chamber.

The backdraft safety device or pressure switch must be functional during boiler operation and their functions must not be affected by anything (for example, a change in position).
If the backdraft safety device or pressure switch fails repeatedly, you must contact an authorized service organization to troubleshoot the problem and carry out an operational test.

open the inlets and outlets of heating water (or utility water) - (valves under the boiler)

open the gas supply to the boiler

When putting the boiler into operation, a qualified specialist from an authorized service organization must:

Check the pump mode - it should be set to stage 3.

Start the boiler according to the instructions

Check the pilot burner flame

Extinguish the pilot burner flame - after 5-7 seconds the main burner should go out

After the pilot burner goes out, check the response time solenoid valve in the gas fittings - after 40-50 seconds a characteristic click should be heard.

Check the function of the boiler switching to reduced power

Perform burner control:
check the main burner, the flame should only be near the outlet openings,
check the stability of the flame along the entire length of the burner plates.

Starting the boiler

The boiler is a fully automatic device. The main burner is ignited automatically by a signal from the boiler automation system from the ignition burner, which is constantly burning. The pilot burner is ignited manually. As additional equipment You can install piezo ignition on the boiler.

The boiler can be turned on and used only after such work has been completed and the room has been thoroughly ventilated.

Modern gas boilers are quite complex technological equipment. With proper care and proper handling, the gas boiler will serve for a long time without any failures. However, even the most expensive and functional equipment has its own resource, after which it begins to appear. various kinds malfunctions.

Knowing the main causes of problems and how to eliminate them, you will be able to repair your gas boiler with my own hands. This is a very painstaking, responsible, but in most cases relatively not hard work.

First of all, it is necessary to establish why any malfunctions may occur in the operation of gas heating boilers. A number of different factors can lead to problems.

Electricity

Modern gas boilers are equipped by various means automation. These products, in turn, are powered by electricity. And, despite the fact that it is already the 21st century and systems for using alternative sources energy, the problem of stability of power grids remains relevant for many regions, especially for remote villages and all kinds of holiday villages.

A sudden shutdown or a strong surge in electricity is one of the main enemies of any modern gas boiler.

To avoid all the associated troubles, buy a high-quality stabilizer in advance. Do not spare money to purchase this device - cheap models are of little use, so it is better to immediately allocate funds to purchase a good stabilizer from famous manufacturer. Rest assured, if the automation breaks down, you will spend much more money on its repair and replacement.

Water

Often used at home wall models gas boilers. Such devices are simultaneously responsible for heating the premises and preparing hot water.

The design of wall-mounted boilers includes a flow-through heat exchanger. Low quality hard water with various inclusions - main enemy gas boiler heat exchanger. Moreover, under the influence of low-quality water, the heat exchanger can fail in just one season.

To prevent such damage, install special filters. The best option– a complete water purification system. With it, your boiler will work for as long as possible, and using purified water is much safer for your health.

Installation errors

Any knowledgeable person will tell you: installation and piping of gas heating equipment should only be carried out by qualified specialists.

Even the slightest errors at the stages of installation and connection of equipment can lead to irreversible consequences. For example, incorrectly performed piping in the case of a cast iron gas boiler with a power of more than 50 kW will lead to the fact that when low temperatures the unit will simply crack.

Therefore, if you are not an experienced gas installer, entrust the installation of the boiler to professionals - this way you will save yourself from many problems in the future.

Weather

Unfavorable atmospheric phenomena can also lead to many different problems. During frosty winters, people turn the heating on almost all the way full power. This leads to a significant decrease in pressure in the gas pipeline system. As a result, boilers cannot reach their full potential.

You will not be able to solve this problem on your own - you still cannot explain to your neighbors that their actions are only aggravating the situation. As a solution to the problem, you can install an additional boiler that runs on a different fuel.

Is it worth repairing the boiler yourself?

A modern gas boiler is a complex and potentially dangerous system. The main danger of such units is the risk of a gas explosion in case of improper handling of the equipment or untimely elimination of various problems.

Various types of automation are responsible for maintaining the operation of the gas boiler at an optimal level. An inexperienced user is often unable to understand its structure. Therefore, to resolve serious problems, it is better to immediately invite specialists.

On your own, you can try to eliminate only visible damage and various contaminants that have led to the failure of the pipe, chimney and other parts of the boiler.

There are a number of typical problems that, in most cases, you can fix yourself. Problems will also be listed, in the event of which you can only protect yourself until a specialist arrives.

If there is a distinct smell of gas or smoke in the room, immediately turn off the boiler and leave the room, opening it for ventilation.

Call a specialist immediately. Trying to solve a gas leak problem on your own without the necessary skills is extremely dangerous and unwise.

Flame sensor failure

If the combustion sensor or gas supply pipe is broken, turn off the boiler and turn off all gas valves and allow the unit to cool completely.

After some time, return to the room to check for the smell of gas. If everything is fine with the draft, try turning the boiler on again. If there is no traction, immediately call a repairman.

Boiler overheating

Overheating is one of the most common problems with modern gas boilers. The reason for this may be a malfunction of automation equipment or a clogged heat exchanger.

Automation repairs cannot be handled without the appropriate knowledge.

You can clean the heat exchanger yourself. The most common materials for the manufacture of heat exchangers are copper and stainless steel. Cleaning them usually isn't a problem, but still be careful.

To clean the heat exchanger, simply remove it and thoroughly clean it with a wire brush. In case of copper heat exchanger, it is better to replace the brush metal sponge used for washing dishes.

Charge fan malfunctions

The problem with fans is their bearings. If your boiler fan stops developing the set number of revolutions, try to fix the problem as soon as possible.

To do this, remove the back of the fan, remove the stator and lubricate the bearings. Perfect for lubrication machine oil, but if possible it is better to use a higher quality carbon composition with heat-resistant properties for this.

It can also lead to problems with the fan. turn-to-turn short circuit. Only a specialist can cope with troubleshooting this problem. Submit the stator for repair to replace the winding, or immediately replace the faulty unit with a new device.

Chimney problems

Often, various malfunctions in the operation of the gas heating boiler Causes excessive clogging of the coaxial chimney.

Remove the chimney and thoroughly clean all its components of soot. This way you will not only return the previous level of efficiency of the unit, but also significantly increase the coefficient useful action boiler

Basic error codes

If a malfunction is detected, the Mora boiler itself signals this. The error is displayed on the display and, knowing the decoding of error codes, you can easily understand what the problem is.

Such errors are corrected by checking the corresponding unit and replacing failed parts:

1. Error e1 - low pressure in the system
2. Error e2 - unit overheating
3. Error e3 - reserve
4. Error e4 - water temperature sensor is faulty
5. Error e5 - the memory unit has failed
6. Error e7 - control potentiometer is broken

During boiler operation, minor errors related to temperature parameters are possible:

Other faults

When not very serious problems, LED button flashes yellow with a frequency of 1 Hz. In this case, there is a possibility that the boiler itself will correct the malfunction, but in this case its power will be reduced.

In the event of a serious malfunction, the LED button constantly lights up yellow, and the boiler stops heating and turns off after 9 seconds. In such a situation, you will have to call a specialist.

Design and principle of operation of Mora boilers

Czech gas single-circuit and double-circuit Mora boilers are available in three modifications. Meteor - double-circuit flow wall-mounted boilers heating. The principle of forced air injection is used, as well as smoke removal - using a fan.

It has a modular burner, which makes it possible to adjust exactly the power required for operation. There is also a setting for the pressure of the hot water supply and the heating system - you can set limit values ​​that will not allow the burner to ignite.
