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.
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.

MORA 5119, 5123
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 maintain safe distances from the boiler to walls made of flammable material and about ways to protect them
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.
The pump runs constantly. The operation of the boiler is controlled by a control and regulation unit in accordance with the heating water temperature set by the User using the control knob on the boiler panel
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.
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 heating system, household 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 elements are supplied upon additional request.
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- will close the gas supply to the boiler when the maximum permissible water temperature in the heat exchanger is exceeded.
Fuse reverse thrust(boilers with exhaust of combustion products 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 combustion product exhaust pipes become clogged (even partially), or fuel combustion deteriorates (it will be lower established norm) under the influence of a decrease in fan speed (voltage drop in the electrical network), or the fan will not work, then thanks to the pressure switch the boiler will not turn on so that combustion products do 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, contact an authorized service organization to troubleshoot the problem and perform an operational test.
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 for installation required temperature heating water 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 only ready for the process of heating domestic water. This mode is mainly used in summer period 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
- thermometer installed on the boiler casing
- the "ON/OFF" button and the heating water adjustment button are located on the left, under the boiler
When preparing the boiler for operation, you must do the following:
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
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.
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.
Boiler ignition sequence
Set the gas valve control knob (located under the boiler casing) to the “pilot burner ignition” position. Keeping the handle pressed in this position, manually light the ignition burner (if there is an additionally installed piezo ignition, press the piezo ignition button several times until the ignition burner lights up);
After igniting the pilot burner, continue to hold the gas valve button (approximately 5-7 seconds). Then release and make sure that the pilot burner is burning steadily;
turn the gas valve handle into operation 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 working if disassembled hot water.
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 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
Before starting operation, the User must carefully and thoroughly study the “Operation Manual.”
Any manipulations or operations with the boiler that do not meet the requirements of the “Operation Manual” are unacceptable.
Installation, commissioning, preventive examinations and troubleshooting should only be carried out by trained specialists from a service organization authorized by the manufacturer that has 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.
Gas MORA 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 that could change the environment (for example, working 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.

How safe are Mora-Top boilers? Mora-Top boilers are equipped with all the necessary elements to ensure safe operation:
Without water flow or if there is no water in the heating system, the burner will not turn on.
Without sufficient DHW flow and sufficient pressure in the heating system, the burner will not turn on.
The burner flame is controlled using a thermocouple, which prevents gas leakage.
If the chimney is clogged, thanks to the backdraft fuse, the boiler prevents combustion products from entering the room.
If the fan malfunctions, ignition will not occur; the manostat will prevent the boiler from starting (Turbo version).
Electronic regulation and a temperature limiter in the heat exchanger will prevent overheating of the water and heat exchanger when emergency situation, taking the boiler out of operation.
MORA boilers, like other boilers, require boiler maintenance for trouble-free operation; if the unit stops, then.
A single-circuit boiler differs from a double-circuit boiler. The question is what? It is certain that single-circuit gas boilers have only one heating circuit. In other words, this means that a single-circuit boiler is intended only for heating houses. To organize a hot water supply system, it is necessary, in this case, to use a hot water boiler, which is purchased additionally (a list of recommended boilers is given in the description of each single-circuit boiler), or a gas water heater, which is installed separately. Unlike the first, double-circuit gas boilers have two circuits, one circuit is intended for heating, the second for heating domestic water (). This means that a double-circuit boiler is used for both heating and hot water supply. Boilers are both wall-mounted and floor-mounted, with open camera combustion and closed, atmospheric gas burner and a forced-air burner. Let's look at what a floor-standing gas boiler with an atmospheric burner with an open combustion chamber is. 
A floor-standing cast iron gas boiler with an atmospheric burner is heating device, intended for heat supply of objects for various purposes. Depending on the power and number of installed boilers, these can be apartments, cottages, apartment buildings residential buildings, administrative and industrial buildings and structures. Heat exchangers can be steel, copper or cast iron. The heat exchanger of the MORA-TOR floor-standing boiler is made of high-strength gray cast iron. Cast iron heat exchangers boilers, unlike steel ones, are not subject to low temperature corrosion and have high thermal conductivity. It should be noted that the atmospheric burners of MORA-TOP floor-standing gas boilers are simple and reliable in operation, operate almost silently and consume very little electricity. When developing MORA-TOP boilers, it was possible to ensure maximum resistance to pressure changes in gas networks and operation at low gas pressure.
Wall-mounted gas water heater. What is it? Wall-mounted gas water heater (boiler or geyser) is a device designed for preparing hot water. The energy source of a gas water heater is gas. There are two types of gas water heaters - instantaneous and storage. When instantaneous water heaters cold water enters, passes through a heat exchanger, heats up and hot water comes out. IN storage water heaters for heating cold water it takes some time. After heating, when the tap is opened, this water enters the water distribution network, gradually being replaced in the tank cold water. When the supply of hot water is exhausted, it takes time again to heat a new portion of water. Instantaneous gas water heaters are more common and convenient to use. The flow principle of operation ensures the high efficiency of this device, since gas is consumed only at the time of water collection. What is a wall-mounted gas boiler? A wall-mounted gas heating boiler is a heating device intended for heating houses and apartments and for hot water supply to premises for various purposes. As a source of energy gas boiler heating is most often used natural gas, less often methane or propane - butane. Gas wall-mounted boilers MORA have expansion tank and a circulation pump, which eliminates the need for their additional purchase and installation. Gas boilers Mora-Top heating systems are compact in size and Beautiful design, thanks to this, the devices can easily fit into the interior of a kitchen or bathroom.
