Boiler installation. Commissioning

During installation, commissioning and maintenance of the boiler, it is necessary to observe certain rules established by state standards and the requirements of the manufacturer. The user must carefully study the "Operation Manual", "Warranty Card" and further be guided by the rules set forth in them.

Installation

For installation of the boiler, as well as for its further safe and economical operation, it is necessary to have a qualified project for the entire heating system. The boiler may only be installed by a specialized service organization authorized by the manufacturer. Only the type of gas that is indicated on the type plate of the product can be used for the operation of the boiler. The installed and assembled boiler must not be moved to a new location. The boiler must be installed in such a way that the socket for the electrical connection of the boiler is located in an accessible place. If it is necessary to intervene in the operation of the boiler, it is imperative to pull out the plug from the mains socket. The boiler is designed to be mounted on a wall made of non-combustible material. On the boiler itself and at a distance of 100 mm from it there should not be objects made of combustible materials.

Main dimensions

MORA 5120, 5121, 5124, 5125


MORA 5119, 5123


Commissioning

The commissioning of the boiler can only be performed 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 of an authorized service organization is obliged to carry out the following:

    check tightness of connections

    to adjust the boiler (if necessary)

    control all functions of the boiler

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

    notify the User of the need to comply safe distances from the boiler to walls made of combustible material and how to protect them

Description of the boiler

Heating - with attached room thermostat

The boiler will start working when it receives a signal from the room thermostat to reduce the temperature in the heated rooms.
After receiving the signal, the pump accelerates, and the gas valve opens the gas flow 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 (set) 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.

Heating - without room thermostat

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

Domestic hot water heating (combined boilers)

Domestic hot water heating has priority over heating water heating.
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 control 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 heated heating water to secondary heat exchanger domestic water is heated.
After the end of the selection of warm utility water, the boiler will automatically switch to the heating process.

Domestic hot water heating (standard boilers)

Boilers designed 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 by warm heating water ("WATER-WATER" system).
When installing the boiler together with a storage water heater, it is necessary to use a three-way valve with an internal microswitch, as well as room thermostat- These items are available upon request.

Security systems

The safe operation of the boiler is ensured by the following elements:

    Heating and utility water flow sensors- they will not allow ignition of the main burner with insufficient water flow.

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

    Backdraft fuse (boilers with flue gas discharge into the chimney)
    If contamination 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 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 gases "TURBO")
    If there is a blockage 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 the fan speed (voltage drop in the mains), or the fan does not work, the boiler will not turn on thanks to the pressure switch, so that combustion products do not accumulate in closed chamber combustion.

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.

Boiler operation

Control Panel

The control panel in the 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 by approximately 100 mm.

Mode switch "SUMMER-WINTER" (installed only on combined boilers)
When the switch is set to the "WINTER" position, the boiler is prepared for operation - heating heating water or utility 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 the heating water at the outlet of 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 on the left, under the boiler

Preparing the boiler for work

When preparing the boiler for operation, the following must be done:

    check the water pressure in the heating system

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

    open the gas supply to the boiler

A qualified specialist of an authorized service organization, when putting the boiler into operation, must:

    Check pump mode - must be set to stage 3.

    Start the boiler according to the instructions

    Check pilot burner flame

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

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

    Check the function of switching the boiler to reduced power

    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.

Boiler start

The boiler is completely automatic device. The main burner is ignited automatically by the signal from the boiler automation from the pilot burner, which is constantly on. The pilot burner is manually ignited. As additional equipment piezo ignition can be installed on the boiler.

Boiler ignition sequence

    set the gas valve control knob (located under the boiler casing) to the position "ignition of the pilot burner". Keeping the knob pressed in this position, manually ignite the pilot burner (in the presence of an additionally installed piezo ignition, press the piezo ignition button several times until the pilot burner ignites);

    after ignition of the pilot burner, continue to hold the gas valve button (approximately 5-7 seconds). Then release and make sure that the pilot burner burns steadily;

    switch the gas valve handle to the operating mode. The boiler is ready for operation;

    turn on the "ON / OFF" button - the button will light up. In the "Winter" mode, the main burner will light up, in the "Summer" mode, the boiler will start to work in case of hot water analysis.

Boiler decommissioning

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

    unplug the power cord from the socket

    close the gas and water supply valves

short term

    move the ON / OFF button to the "OFF" position

    leave the power cord plug in the socket

    leave gas and water supply valves open

Prevention. Maintenance. Boiler Operation Safety

    Before starting operation, the User is obliged to carefully and thoroughly study the "Operation Manual.

    Any manipulations and operations with the boiler that do not meet the requirements of the "Operating Manual" are unacceptable.

    Installation, commissioning, preventive inspections and troubleshooting must be carried out only by trained specialists of a service organization authorized by the manufacturer, having the necessary state approvals and licenses. Information about all manipulations and operations with the boiler must be entered in the "Warranty Card".

    During operation, the User must periodically monitor its operation.

    MORA gas boilers must not be used for purposes other than those specified in the "Operating Instructions".

    The boiler must be turned off if work is being carried out in the room where it is installed, which can change the environment (for example, work with paints, adhesives, etc.). The boiler can be turned on and used only after such work has been completed and the room has been thoroughly ventilated.


The device and internal design, which the Czech gas boilers Mora Top have, made it possible 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 boilers Mora Top have three basic modifications:


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

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 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. 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 make sure 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 faults double-circuit boiler is a thermocouple failure. 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 Rules exploitation also ensure the popularity of the Czech Mora models.
