The last step installation of almost any heating system is its first trial run, debugging and commissioning. By by and large, if boiler equipment is launched for the first time, then this work is a priority for service centers. During the first start-up, the specialists of the service center check the correct connection of the boiler, debug it and put this equipment under warranty. If you carry out the first launch yourself, then you can not count on the warranty service center. Starting and debugging the heating system can also be carried out during the operation of the system - you will not turn to specialists every time. Owners individual heating you just need to know the process. We will study it with you in this master class with step by step photos, in which, together with the website, we will study in detail the issues of how the boiler is started up and how the heating system is debugged with our own hands.

Filling the heating system with water

launch gas boiler starts with filling the heating system with water. Everything is simple here - modern double-circuit boilers do not require the device of a special unit for feeding the system. It is already built into the boiler and is equipped with a special faucet, which, as a rule, is located at the bottom of the boiler in close proximity to the connection pipe. cold water. Open the make-up tap and slowly fill the system with water.

Starting the boiler - how to fill the system with water

A very important point in the operation of any boiler equipment is fluid pressure. To control this parameter of the heating system, almost all boilers are equipped with a pressure gauge. In the process of filling the systems with water, it is necessary to monitor the pressure and after it reaches 1.5-2 atm, the filling of the system will need to be stopped. In principle, the indicator of the operating pressure of the boiler, depending on the manufacturer and model, may vary - therefore exact figure operating pressure, see the instructions for the boiler.

Do-it-yourself first start-up of a gas boiler

Removal of air locks in the system

Better to start with batteries. For removing air locks a Mayevsky crane is usually installed on them. We open it and wait for the water to run. Did you run? We close. Such manipulations must be done with each heater separately.

How to start the boiler with your own hands photo

After the air is removed from the batteries, the pressure in the system will decrease and the pressure gauge needle will drop. At this stage of work, the solution to the question of how to start the boiler involves re-feeding the system with liquid.

Now, the most difficult thing is that starting gas boilers requires venting air from the circulation pump. To do this, the boiler needs to be disassembled a little. Remove the front cover and look for an object cylindrical shape with a shiny cap in the middle, with a slot for a screwdriver. After we have found it, we put the boiler into operation - we feed it power supply and set the water heating regulators to the working position.

Releasing air from the circulation pump when starting the boiler photo

The circulation pump will immediately turn on - you will hear a faint hum and a loud gurgling and many incomprehensible sounds. This is fine. As long as the pump is airy, it will be so. We take a screwdriver and slowly unscrew the cover in the middle of the pump - as soon as water begins to seep out from under it, we twist it back. After two or three such manipulations, the air will come out completely, incomprehensible sounds will subside, the electric ignition will work and start working. We check the pressure again and, if necessary, add water to the system.

Basically, everything. While the system is warming up, you can do a detailed study of the instructions (if, of course, you have not already done so) and debug the system, which involves starting the boiler. Everything is simple here - the batteries closest to the boiler must be screwed on, and the distant ones should be run to the fullest. Such debugging is carried out by means of control valves installed on the pipe connecting the supply to the heating radiator.

Ariston Clas

Gas wall Ariston boilers Clas: 24FF, 24CF, 28FF/CF, 15FF/CF, 32FF

SIT 845 SIGMA gas valve - Ariston Class boilers use a SIT 845 SIGMA gas valve with two electromagnets powered by 220 V alternating voltage to supply and cut off gas to the burner. To regulate the gas flow at the outlet of the valve from the ECU in accordance with the readings of the temperature sensors, a low-voltage (24 V) regulator is used. This block is used for both natural and liquefied gas. The valve is also equipped with a NAC504 that supplies voltage to the main burner ignition transformer and valve. The valve is designed to work with different gases without replacing components. Only the injector needs to be replaced. Gas pressure at the inlet to the valve - no more than
6 kPa (60 mbar). Components: gas supply to the burner, supply pressure sensor, maximum power adjustment nut, inlet pressure sensor, inlet fitting, ignition device, minimum power adjustment screw, compensator.

- Change parameter 220.

Adjustment of the heating start delay: Regulation is carried out using parameter 236. The boiler allows adjustment of the delay time from the receipt of the heating command to the ignition of the burner in the range from zero to 7 minutes. The regulation is carried out using parameter 236.

Adjustment of the maximum heat output: The appliance has two different maximum outputs: in DHW mode and a smaller one in CO mode (absolute maximum value). The absolute maximum heat output is set in parameter 230. This parameter must only be checked and, if necessary, modified in the event of a changeover to another gas group. To control the heat output in heating mode, it is possible to control the maximum heat output (in the range from the minimum to the absolute maximum value). The boiler allows you to adjust the delay time from the receipt of a heating command to the ignition of the burner in the range from zero to 7 minutes. Regulation is carried out using parameter 236. Regulation is carried out using parameter 231. The device allows you to regulate the maximum value of the heating output.

Main burner - In the Ariston Clas 24 FF / CF, 28 FF / CF, 15 FF / CF, 32 FF boiler models, Polidoro burners with a nozzle pitch of 19.0 mm are used. The electrodes (two ignition electrodes and one flame control electrode) are combined into a block. The gap between the ignition electrodes should be 4 ± 1 mm, the distance between the electrodes and the burner should be 8 ± 1 mm. Distance between flame detection electrode and burner
should be 8 ± 1 mm. If the burner does not ignite after the safety delay has elapsed, code 501 is displayed on the control panel indicator. The ion current must be at least 1 μA. Electrode voltage relative to ground 110 V alternating current.

Ariston Clas Evo

Modifications of gas boilers Ariston Clas Evo: 24 FF, 24 CF, 28 FF, 15 FF

Boiler hydraulic unit

Right hydraulic unit - Modular unit with built-in functional elements: CO and DHW filter. All elements are attached to the clamps. Pump block with deaerator valve. Brass fittings for mounting. Filling tap.

Left hydraulic unit - Modular unit for supplying hot water to heating and hot water circuits: CO safety valve 0.3 MPa (3 bar). Automatic bypass. Brass fittings. Everybody copper tubes fastened with fasteners.

Three-way valve- The three-way valve is used to change the distribution of water (to the heating circuit or to the secondary heat exchanger). The valve is controlled from the electronic control unit (ECU) through a relay contact. The valve consists of a body made of composite material, and an electric drive (engine). When the machine is in standby mode, the valve is in the “SANITARY” position. Procedure for switching the 3-way valve. The boiler is in standby mode, the valve is in the “SANITARY” (DHW) position: When the heating is switched on: the start of the operating cycle in the “Heating” mode is delayed by 7 s (time required for the valve to switch electrically from “DHW” to “CO” ). When a command is received for DHW: the unit immediately starts operating in the “DHW” mode.

Valve in position “HEATING” (CO): When a DHW command is received: the valve switches from “CO” to “DHW”, while the pump and burner continue to work. After receiving a command for DHW: if the command for heating is not canceled, the pump and the burner are switched off for 7 s (the time required for the valve to switch from “DHW” to “CO” by means of an electric actuator. The Clas Evo System boiler starts working again in the “Heating” mode "". The 3-way valve is driven by an easily dismantled ELBI electric motor. The electric motor can be replaced without draining the water from the boiler. It is enough to remove the lock and disconnect the power wire. The signal from the ECU goes to the engine in accordance with which mode (CO + SHVS or DHW only) is set on the control panel.The valve has two limit switches (right/left) that cut off the servomotor when the required position is reached.

Secondary heat exchanger - The secondary heat exchanger of the Ariston Klas Evo 24 ff boiler is attached to the hydraulic unit with two screws. The screw holes are located asymmetrically on the heat exchanger housing, so that it can only be installed in the correct position. Descale protection temperature setting - Aims to reduce the formation of scale in the secondary heat exchanger. In DHW mode, the burner turns off and on depending on the readings of the NTC1 and NTCs temperature sensors.

Pump block. Pump type: models 24 and 28 kW. Wilo MTSL 15/5 HE-2; model 32 kW. Wilo MTSL 15/6,7-2 CLF12. The ECU allows you to control the switching of the circulation pump from one speed, V2 (55 W), to another, V3 (80 W). In DHW mode, the pump always runs at V3 to ensure the best heat transfer. In heating mode, the pump can operate at one of two speeds. The value is determined by the temperature difference at the water supply to the heating circuit and the return fitting (dT). Procedure: Tsub.-reverse. T - 2 C more than V2; Tsub.-reverse T is greater than V3 where T= 20C (set by parameter 239 between 10 and 30C).

Switching to both smaller and greater frequency rotation is carried out with a delay of 5 minutes (unchangeable value). Parameter 238 of the Ariston Klas Evo boiler allows you to prohibit switching the pump from one speed to another: 0: fixed. rotation frequency 2; 1: fixed rotation frequency 3; 2: adjustable. The anti-sticking system turns on the circulation pump and the 3-way valve for 15 seconds every 21 hours from the last action. The value of parameter 823 can be used to monitor the pump speed, or the voltage (AC) between pins 5 and 6 of connector CN10 of the electronic control unit can be measured: 145 V: maximum speed; 0 V: lowest speed;

Filling the heating circuit manually - The procedure for filling the CO circuit (empty) is as follows: Open the tap at the inlet of the cold mains water. Remove the deaerator cap. To open the filling valve, use the magnetic key (attached under hydraulic unit) set the filling valve to the valve open position, the filling of the CO circuit starts.

Semi-automatic heating circuit make-up - The “Semi-automatic make-up” mode should only be used if the primary circuit needs to be made up. Do not use to fill an empty system. An alternating voltage of 230 V is supplied to the solenoid valve of the recharge (pins 1 and 2 of the CN12 connector of the computer), a resistance of 3.7 kOhm. In DHW mode, this mode is not active. Parameter 248 allows semi-automatic make-up to be disabled: 0: disabled; 1: allowed.

If the pressure in the system is less than 0.6 bar, the make-up mode is activated, the icon is displayed on the display of the Clas Evo System boiler; in this case, pressing the button 13 starts the cycle “Filling the system”:

The three-way valve switches to the CO position;
- If the pump was turned on, it turns off;
- if the burner was turned on, it turns off;
- after the first filling, pressure control is carried out; if the control result is negative, an error message 1P5 is generated (between B and A);
- control of constancy of pressure is carried out; if the control result is negative, an error message 6P1 is generated (between C and B1);
- to achieve the set pressure value, a second filling cycle is carried out.

Ariston Clas Evo boiler error codes (when filling)

Error 102 - The pressure sensor is not connected or there is a short circuit in it.
Error 109 - The pressure is higher than the maximum (3 bar).
Error 111 - The pressure is below the minimum (0.4 bar).
Error 1P4 - The pressure is lower than displayed (0.6 bar).
Error 1P5 - The first filling cycle was not completed successfully (the pressure in the boiler did not increase): press the appropriate button and try to fill again.
Error 1P6 - Pressure constancy control gave a negative result: press the appropriate button and try to fill again.
Error 1P7 - More than 5 filling cycles in 50 minutes, the filling button is blocked (to reset: disable and re-enable).
Error 1P8 - More than 6 filling cycles in 7 days, the filling button is blocked (for reset: Off-On).

Pressure sensor in the heating circuit - The proportional pressure sensor is designed to measure the pressure in the primary circuit. The measured value is displayed on the display of the boiler Ariston Class Evo 24 ff. The control is carried out by measuring the voltage (DC) between pins 8 and 9 of connector CN04. Correspondence of voltage and pressure values: 0 bar = 0.3 V, 1.5 bar = 2.5 V, 3 bar = 4.8 V. and exit), a protective shutdown 102 is carried out.

Bypass - The bypass in the boiler switches automatically, this unit does not need to be adjusted. In the event of pressure loss in the CO circuit due to thermostat or zone valve operations, the bypass ensures that the water flow through the main heat exchanger is at least 350 l/h. In addition, an automatic bypass prevents overheating of the heat exchanger, which can occur if there is insufficient water flow. In this case, the temperature in the boiler is adjusted in the usual way, when the temperature setpoint is reached, the burner is turned off. The bypass is located in the supply unit and is interlocked with a three-way safety valve.

Primary heat exchanger - The primary heat exchanger of the Ariston Clas Evo 24 FF, 24 CF, 28 FF, 15 FF boiler is made of copper with an anti-corrosion silicone coating. It is designed to transfer the heat of combustion products to water in the primary circuit. There is an overheating sensor with automatic reset, triggered at 102 ± 4 C. Model - Number of fins / dimensions: 24 CF - 82 / 260 x 180 mm, 28 CF - 89 / 300 x 180 mm, 24 FF - 91 / 260 x 180 mm, 28 FF - 91 / 260 x 180 mm, 32 FF - 105 / 300 x 180 mm .

Expansion tank - When the water temperature rises, the expansion tank compensates for the increase in its volume. The tank consists of two compartments separated by a styrene-butadiene rubber membrane. One compartment is filled with nitrogen, the second receives water from the primary circuit. The nitrogen compartment can shrink as the volume of water increases as the temperature rises. The expansion tank is designed for a heating system with a water volume of about 175 liters. Specifications- Capacity - 8 liters. The largest working temperature- 90 C. Nitrogen pressure - 0.1 MPa (1 bar). Greatest operating pressure- 3.0 MPa (1 bar).

DHW flow meter - The DHW flow meter has a turbine, which rotates the flow of water in the DHW circuit, and a speed meter, the signal from which is sent to the Clas Evo System boiler control unit. There is also a cold water filter to prevent contamination of the flow meter. In addition, there is a water hammer protection device (ECU controlled). The setting is parameter 252, which allows
set the response time from 0.5 to 20 s (default 0.5 s). The value of the water flow in the DHW circuit is indicated by parameter 825. It can also be displayed on the display by pressing the INFO button. For control, you can measure the voltage (DC) at connector CN14: 0 V = no flow; 5 V = no flow; 2 to 3 V = flow available. Water analysis is available: 100 l / h. There is no water analysis: 80 l / h.

Ariston Genus

Gas boilers Ariston Genus are designed to supply heat and are installed in residential buildings and premises. Models of wall-mounted boilers Genus: 24 FF, 35 FF, 24 CF, 30 FF.

Elements of FF models. Sealed combustion chamber - Air inlet of a two-channel gas duct, Air pressure switch, Steam trap at the inlet of the air pressure switch, Coolant overheating sensor, Primary heat exchanger, Temperature sensor (with negative temperature coefficient) heating water supply (NTC 1), Burner and electrodes, Gas valve and
spark ignition generator, DHW temperature sensor (NTCs). Safety valve 0.3 MPa (3 bar), Pump, CO return water temperature sensor (NTC 2), Infinitely variable fan, Flue gas sampler, Flue outlet for flue gases, Hall sensor.

Elements of CF models. Open combustion chamber - Flue pipe, Flue gas temperature sensor, Coolant overheating sensor, Temperature sensor (with a negative temperature coefficient) of water supply to the CO circuit (NTC 1), Burner and electrodes, Gas valve and spark ignition generator, DHW temperature sensor ( NTCs), Safety valve 0.3 MPa (3 bar), Pump, Water temperature sensor (NTC) on the CO return connection (NTC 2), Primary heat exchanger.

The order of operation of the Ariston Genus boiler in heating mode - The heating command can come from: room thermostat 1, room thermostat 2, timer-programmer, remote control remote control REMOCON and room temperature sensor. The display shows C, then the flow temperature to the CO circuit (measured by the NTC1 probe). When the machine is in standby mode, the valve is in the “SANITARY” position. When the heating is turned on, the servomotor that blocked the output of the secondary heat exchanger is activated (the shaft extends), the pump input is connected to the heating circuit. The circulation device is started with a delay of 7 s after the heating command, so that the three-way valve has time to switch; after that, the circulation device directs water from the return fitting to the primary heat exchanger.

The fan turns on (sealed chamber models). After the pressure switch trips, the machine can proceed to the next step (in this case, the pressure switch tripping is not checked again until the next restart). If the relay fails, after 20 s the machine performs a safety shutdown 6P1, the fan continues to rotate until confirmed (sealed chamber models). After the air pressure switch is activated, the gas valve and the spark ignition generator are switched on. Gas supply is carried out at the rate of 80% of the ignition power in soft mode; given value can be adjusted using parameter 220. The presence of a flame is monitored by ion current (using a control electrode). Error indication 5P1 indicates a lack of ignition.

The Ariston Genus boiler makes an attempt to ignite in soft mode (at 90% power). In case of failure, fault 5P2 is displayed on the indicator, a third ignition attempt is made at 100% ignition power in soft mode. If the third attempt is also unsuccessful, the device stops. Guard delay 8 s. For control, temperature sensors are used at the flow to the circuit and the return fitting. The values ​​of dT sub.-arr. are used. and the rate of temperature rise at the supply and return fittings. The pressure is measured with a pressure transducer. After detecting a flame in the apparatus, the heat output can be adjusted in accordance with the required heat output. Adjustment can be carried out in the entire range of thermal power values ​​- from the maximum (set from the control panel - parameter 231) to the minimum (fixed; installed on the gas valve).

The burner shutdown temperature is adjusted as follows:

1st minute after flame detection: T off = T set. + 8C
- 2nd minute after flame detection: T off. = T set. +6C
- from 3 minutes after flame detection: T off. = T set. +4 C

This arrangement prevents the burner from switching off too quickly when the temperature setting is reached. It is possible to set the delay before switching on again from 0 to 7 minutes (default 2 minutes, set from the control panel - parameter 236). The pump can operate at one of two speeds. The value is determined by the temperature difference at the water supply to the CO circuit and the return fitting. Protection against overheating is carried out using a temperature sensor with automatic reset (102±4C) at the supply to the CO circuit (even when the burner is off). When the sensor contacts are opened, the burner is switched off protectively, and after 5 s, if the contacts are still open, the device is blocked (not allowing it to be turned on again by the operator), the display shows error 101. From the moment the heating command is received, the “limit temperature” signal (88 C, fixed value) comes continuously from the supply water temperature sensor to the heating circuit (NTC 1). If the circulation in the CO circuit is disturbed, it is possible to automatically switch to the bypass (capacity not more than 350 l / h).

The operation of the Ariston Genus boiler in DHW mode - The water flow in the DHW circuit is measured using a flow meter. The boiler is now operating in SANITARY mode. The display shows the letter d and the temperature setting. When the machine is in standby mode, the valve is in the “SANITARY” position. If a DHW command is received while the machine is operating in CO mode, the three-way valve switches to the SANITARY position. In this case, the circulation pump and the burner continue to work. The outlet of the secondary heat exchanger is connected to the inlet of a pump that supplies water to the primary heat exchanger. The pump (speed 3) pumps out water from the secondary outlet and sends it to the primary heat exchanger. The fan turns on at maximum speed (models with sealed chamber). After the air pressure switch has tripped, you can proceed to the next step.

If the relay does not work, after 20 seconds the device performs a protective shutdown (error 6P1), the fan continues to rotate until acknowledged (models with a sealed chamber). In models with an open chamber, instead, control is carried out by an overheating sensor (it works even during the operation of the device). If the overheating sensor of the combustion products is triggered, the apparatus stops 601. After the air pressure switch is triggered, the gas valve and the spark ignition generator are turned on. The gas supply is carried out in accordance with the heat output in the soft ignition mode (set from the control panel parameter 220). The presence of a flame is controlled by
ion current (using a control electrode). Indication 5P1 indicates the absence of ignition. The Ariston Genus 24 CF / FF, 35 FF, 30 FF boiler attempts to ignite in soft mode (at 100% power).

In case of failure, fault 5P2 is displayed on the indicator, a third ignition attempt is made at 100% ignition power in soft mode. If the third attempt is also unsuccessful, the device stops with error 501. Guard delay 8 s. To control the flow of water, temperature sensors are used at the supply to the circuit and the return fitting. The values ​​of T sub.–arr. and the rate of temperature rise at the supply and return fittings. The pressure is measured with a pressure transducer. The burner flame can be adjusted over the entire range of thermal power values ​​- from the maximum (installed on the gas valve) to the minimum (also installed on the gas valve). The burner runs until the anti-scale temperature setting is reached. This temperature is measured by the NTCs sensor in the DHW circuit. Overheating protection is provided by a temperature sensor with automatic reset (102 ± 4 C) at the heating circuit flow (even when the burner is switched off). When the sensor contacts are opened, the burner is switched off safely, and after 5 s, if the contacts are still open, the device is blocked (not allowing the operator to restart it), the display shows error 101.

Operating modes

Chimney Sweep Mode - The mode is used for proper analysis of combustion products and calibration by maximum and minimum values. Press the Reset button and hold for 5 s. If the boiler is in the “Winter” mode, the three-way valve is in the “CO” position and the burner is switched on even without a heating command. The device is in the "Summer" mode: in the absence of a command for DHW, the device operates in the CO mode; if there is a command for DHW, the device operates in DHW mode. In Chimney Sweep mode, temperature measurement (by NTC probe 1) is performed as follows: Summer mode over Off: 86 C; On: 81 C; Winter mode over Off: 89 C; On: 84 C. Press the RESET button to exit Sweep mode. If this is not done, after 10 minutes the device automatically exits this mode.

Comfort mode - In this mode, the Ariston Genus 24 FF, 35 FF, 24 CF, 30 FF boiler starts supplying hot water to the DHW circuit faster. For this purpose, in the primary circuit of the boiler, heat. Press the “C” (comfort) button. In Comfort mode, the display shows the COMFORT icon and the letter C, as well as the temperature measured by the NTC1 sensor. The device switches to Comfort mode for each command on the DHW and maintains it for 30 minutes. To exit this mode, press the “C” button again. Menu parameter 2 50 allows you to set the Comfort mode as follows: 0: disabled; 1: switched on for 30 minutes after the command for DHW; 2: always on.

Frost protection mode - The mode is active only when the ON/OFF switch is in the ON position. The transition to this mode is carried out according to the readings of the temperature sensor at the supply to the CO circuit (NTC1). Temperature measured by NTC1 probe: 3 to 8 C - The pump runs at speed III. The three-way valve switches alternately for 1 minute to the “CO” mode, for 1 minute to the “DHW” mode. The display shows the letter F and the temperature value measured by the NTC1 sensor. Action time: until the temperature measured by the NTC1 sensor reaches 9 C. Temperature measured by the NTC 1 sensor: below 3 C - The burner starts at minimum power; The pump runs at speed III. The three-way valve is in the “CO” position. The display of the Ariston Genus boiler alternately displays the letter F, the number 2 and the temperature value measured by the NTC1 sensor. Action time: until the temperature measured by the NTC 1 sensor reaches 30 C.

If the NTC 1 supply temperature sensor in the CO circuit does not work (open or a short circuit occurs), the transition to the “Frost protection” mode is carried out according to the readings of the NTC 2 sensor on the return fitting, but in this case only the pump works (the burner does not turn on) . The display does not indicate the frost protection mode, but the NTC 1 sensor error code 110 in case of a short circuit or open circuit. The unit goes into frost protection mode even if the NTC 2 sensor is not active (open or short circuited), but in this case only the pump works (the burner does not turn on). The display does not show the designation of the frost protection mode, but the NTC 2 sensor error code 112 - a short circuit or open circuit. The machine goes into frost protection mode even if there has been a shutdown due to no flame detection, error code 501, or a blockage due to overheating, error code 101, but in this case only the pump is running (the burner does not turn on), and the display shows the display does not indicate the frost protection mode, but the lockout error code. In case of shutdown
power supply, all settings are saved in the device, and after power is restored, it switches to the mode in which it worked before the shutdown.

Ariston Genus boiler combustion products removal system

On the outside of the apparatus there is a flue gas collector with two samplers for determining the temperature of the flue gases and air at the inlet, the content of O2, CO2, etc.

Air pressure switch - To control the proper removal of combustion products, the device is provided with a pressure switch. 25 kW: Open = 50 Pa (0.50 mbar); closed = 60 Pa (0.60 mbar); 30 kW: Open = 74 Pa (0.74 mbar); closed = 89 Pa (0.89 mbar); 32 kW: Open = 74 Pa (0.74 mbar); closed = 89 Pa (0.89 mbar); The first pressure value is taken at the outlet of the fan (nipple “L” of the pressure switch). The second pressure value is taken in the combustion chamber (nipple “H” of the pressure switch). Both values ​​are negative (below atmospheric), but the pressure switch monitors the difference in the indicated values ​​(to measure this difference, you can connect a differential pressure gauge to the pressure taps located on the top of the device). During operation of the Ariston Genus boiler, the contacts of the pressure switch are closed. The device responds to opening contacts. 607: Pressure switch contacts closed before start of ignition sequence. 6P1: The pressure switch contacts are not closed, although the fan has turned on.

Variable Speed ​​Fan - The following fans are used: 24 kW: with 35 W motor; 28 kW: with 45 W motor; 32 kW: with 60 W motor; A Hall sensor is used to measure the fan speed. Upon receipt of a command for heating, the ECU starts the fan at maximum speed (up to 2800 min–1). After the pressure switch is activated, the fan switches to the ignition speed (different for DHW and CO modes), which allows optimizing the ignition of the burner. Once the presence of a flame has been detected by means of a control electrode, the fan speed can be controlled according to the required heat output.

The fan speed is regulated in accordance with the gas supply through the gas valve in the direction of increasing or decreasing, respectively, more or less current is supplied to its winding. For speed control on front side fan has a Hall sensor. If the fan speed falls more than 100 min-1 below the minimum speed (1750 min-1) within 10 s, or if the connection to the Hall sensor is detected, error 604 is output: fan off delay: 40 s at maximum speed ; 2 min - at the minimum. To control the fan speed in min-1, use parameter 8 22 or measure the frequency of the signal between pins 4 and 5 of connector CN07. Parameter 222 makes it possible to disable the switching of the pump from one speed to another: 0: adjustable; 1: fixed.

Ventilation shutdown delay - The fan operates with a shutdown delay: 40 s at a frequency of 1900 min–1 (after trips 501 and 103); 20 s at maximum speed (after no water circulation shutdowns: 103, 104, 105, 106 and 107), 10 s at 1900 min–1 (after no water circulation shutdowns: 1P1, 1P2 and 1P3); 5 s for 1900 min–1 (after each shutdown of the burner).

Fan off delay after heating command: parameter 243= 0: 5 s for 1900 min-1 (every time after burner off); parameter 243= 1: 3 min for 1900 min–1 (every time after the burner has been switched off).

Fan stop delay after DHW command: parameter 254= 0: Tsub. less than 75 C = turns off without delay; Tsub. more than 75 C = 3 min (minimum speed); parameter 254= 1: 3 min (fixed time, minimum speed).

Combustion products control (boilers Ariston Genus 24 CF, open combustion chamber) - An overheating sensor with automatic reset, installed in the flue gas duct, sends a signal to the computer, which ensures proper control, provided that the computer has power. When the overheating sensor is triggered, the device is switched off protectively, the error code 601 is displayed on the indicator. Reason for triggering: The temperature in the combustion products outlet path exceeded the sensor triggering setting, 75 ± 3 C. After 12 minutes, the sensor is automatically reset, since the temperature has time to drop during this time . To immediately reset the sensor, you can turn off and then turn on the power to the ECU. Error messages when the overheat sensor is triggered - 601: The overheat sensor has been triggered (safety shutdown). 601: open circuit of the overheat sensor (safety shutdown).

System of removal of products of combustion (tight chamber, models FF) - The device allows the installation of both coaxial (60/100 mm) and two-channel (80/80 mm) gas ducts (respectively, two connection options). Flue gas samplers are built into the throat of the flue gas collector.

Maintenance and start-up of the gas boiler Ariston Uno

Preparing the wall-mounted gas boiler Ariston Uno for work

If the Ariston Uno 24 mi boiler is installed in an apartment, it must be checked that all regulations regarding air supply and ventilation of the room are observed (in accordance with current regulations).

Periodically check the water pressure with thermomanometer "L" and check (when the system is cold) that it is between 0.2 and 1.3 bar.

If the pressure is below the minimum value, it must be restored using the filling valve located at the bottom of the boiler.

When the pressure reaches 0.7 bar, close the valve. If the pressure drop occurs very frequently, there may be a water leak in the system. In this case, the leak must be repaired.

Switching on procedure - Press the "C" button. Electronic device ensures that the burner is ignited without any manual intervention, depending on the command for heating or hot water preparation.

If after 10 seconds the burner does not ignite, the safety devices of the Ariston Uno 24 mi boiler will block the gas outlet and the red light diode “G” will light up.

To turn on the boiler in this case, press the button "B". If blocking occurs again, you should check that gas cock was opened.

Heating regulation - It is possible to regulate the temperature of the water in the heating circuit using knob "A", setting the pointer between the minimum and maximum values. The temperature may vary between 45°C and 80°C.

Control using a chrono-thermostat - If a chrono-thermostat is installed, it is recommended to keep the heating temperature set at the maximum value using knob "A" for a higher efficiency of the Ariston Uno 24 mi boiler.

To approach the internal elements of the Ariston Uno 24 mi boiler, you must:

Unscrew the screws located at the bottom of the boiler;

Turn the mounting plates outward;

Pull the lower part of the front panel forward until the central latches come out and remove towards the top.

When removing the casing and turning the control panel, access to the internal elements of the boiler is opened.

Initial start-up of the boiler Ariston Uno 24 mi

When you turn on the device for the first time:

Make sure that: electrical connections and grounding are done correctly and a two-pole switch with minimum clearance open contacts not less than 3 mm; the plug of the automatic air vent of the heating system is loosened; pressure in the heating system
below 0.7 bar; gas cock closed

Unlock the circulation pump by unscrewing the plug on the front of the pump housing and turning the pump shaft with a screwdriver.

Connect the power supply to the boiler by pressing the button “C” and set the handle “A” between the minimum and maximum marks to activate the “winter” mode. Thus, the circulation pump will turn on; after 7 seconds, a lockout will be activated due to the absence of a flame.

Leave the Ariston Uno boiler in this state until the end of air bleeding.

To remove air pockets, loosen the plug of the deaerator of the circulation pump; re-bleed the air from the radiators; briefly open the hot water tap;

Check the pressure in the heating system, if it has dropped, open the filling valve and bring the pressure to 0.7 bar;

Check that the flue gas system is working properly.

Make sure the required shut-off valves open.

As a rule, we entrust the first start-up of a gas boiler and work on setting up and adjusting it to masters from service centers. Why? Yes, because without their mark in the equipment passport, the manufacturer's warranty is simply not valid, and in the event of an early breakdown, we will simply be denied warranty repairs.

Whether this is actually the case is, of course, debatable. Specialists from the service center will find a million reasons to refuse you free repair equipment. And even if you get such generosity from them, then your repair will last more than one week - then there are no spare parts, then the queue has not yet come, then it’s wrong. This is a proven fact and it is very difficult to disprove it. If you want a quick "warranty repair" - pay both for spare parts and for the work of the master.

By the way, in order to put the boiler on warranty service, you also need to pay money. So what is this guarantee? Pay for the warranty, then pay for parts and repairs. So where is the free warranty service? That is why, since you already have to pay for everything, I suggest that you independently start the gas boiler for the first time and set up the heating system. Moreover, it is not difficult.

Filling the heating system with water

We look under the bottom of the boiler - where all the pipelines are connected, and look for something like a small valve there. For each model of gas boiler, it may have different shape: one manufacturer makes it in the form of a valve familiar to us, the other - in the form of a rotating plastic pin. In general, from their form, the essence does not change - in extreme cases, open the instructions and look at its location.

We open this tap, not completely (so that air does not hang anywhere in the pipes, it is better to fill the system slowly) and fix our eyes on the pressure indicator - the pressure gauge. As a rule, most boilers of this type have an operating pressure of 1 to 3 atm - read the instructions for more details. We wait until the pressure gauge needle reaches 2.5 atm, close the valve.

Now the boiler will have to be left alone for a while - from each installed battery or convector must be vented.

For these purposes, each heater must be equipped with a Mayevsky crane. We open it and wait for the air to come down and the water to run. The water went - they closed the Mayevsky tap. This procedure must be done with each battery. Have you done?

Now we return to the boiler and again look at the pressure gauge - the pressure in the system should drop. We correct it, add water if necessary - the optimal pressure at which the boiler works normally is 1.5-2 atm. If you pump more, then during operation at a high temperature of the coolant, excess pressure will be released. This is due to the fact that when the liquid is heated, its pressure increases.

First start of the gas boiler

Having done all these simple preparations, you can proceed to the direct start of the boiler. Open the gas valve and plug the boiler into the socket. All sorts of symbols and numbers appear on the screen, but for a full launch, you still need to perform some actions.

First, press the power button and set the temperature control knobs to the operating position. After these actions, the boiler will begin to make futile attempts to turn on - this is normal and there is no need to be scared. The most important thing is that the circulation pump has started to work, inside which for some reason there is always air that prevents the boiler from fully turning on. It is his removal that needs to be done as soon as possible.

We remove the front cover of the boiler - in almost all cases it is fastened with two or four screws. We fold back the dashboard, behind which the circulation pump hides.

In the center of the pump there is a wide screw with a slot for a screwdriver. Here it is, dear, and you need to unscrew it a little, and when water runs out from under it without air bubbles, twist it again. Only now will the full circulation of the liquid in the heating system begin, and the boiler will start working.

At first, he will gurgle, make some strange sounds, but this is only for the better. Just be aware that all these sounds indicate that the air remaining in the system is being expelled into the expansion tank, where the automatic air valve releases it outside. Five minutes will pass and the system will return to normal - the pressure will stabilize, and the gurgling sounds will subside. And five minutes later you will already be enjoying warmer batteries and unlimited hot water in the faucet.

Here, in principle, is everything you need to know in order to carry out the first start-up of a gas boiler. The boiler is working, the batteries are getting warmer, and I think you will figure it out for yourself how to regulate the temperature of the batteries and hot water in the tap - read the instructions, everything is intelligibly described there regarding the control of your particular boiler model.

Each owner of his house tries to make it as cozy and comfortable as possible. To achieve this, it is worth thinking about installing an Ariston double-circuit wall-mounted gas boiler, which will help solve problems with heating a dwelling. The device is very useful in that it will provide heat both in an apartment and a private house up to 500 m².

Also, a gas wall-mounted boiler of a double-circuit type Ariston will allow you to quickly heat water for instant use. In this case, a person does not have to connect a boiler, which will require additional investments and separate place for installation.

Descriptions of the double-circuit boiler Ariston

Today, there are many interesting models on the market for gas boilers. This is quite convenient, since everyone will be able to choose a device that is most suitable for the price, type, characteristics and installation method. Double-circuit wall-mounted boilers Ariston gained their popularity due to rare situations with their malfunction, as well as silence during operation, which is very important for maintaining calm environment in home.

One of the most important components in all gas boilers is the burner, in this case it can be modulating or conventional. The first option is more popular than the second. When using it, the entire system will be regulated automatically, without human intervention. In this case, the power of the installed heating equipment depends on the temperature indicators.

The burner is also divided into 2 types:

• open;

It is the safest, since it does not involve the entry of combustion products into the room in case of emergency. Also in this case, the owner may not worry about building a chimney. To the closed burner it is necessary to bring a special coaxial pipe, it can always be brought out in any accessible place.

Boiler Ariston open type, in any case, requires a chimney to bring the products of combustion to the street. Also, do not forget about natural draft. Air will enter the system from the living quarters, so it will have to be constantly ventilated.

coaxial pipe used in closed system combustion, the good thing is that it is made of 2 layers. One is necessary for the withdrawal of combustion products, and the other will ensure the entry fresh air inside the boiler. Thus, the owner of the equipment does not have to constantly ventilate the room and worry about natural draft. The room will always have enough oxygen.

Distinctive abilities

According to reviews of gas wall-mounted double-circuit boilers Ariston, they have 4 distinctive features useful for their owners:

1. All models of this company are equipped with automatic protection systems.
2. The presence of a water pump, which is necessary for the constant circulation of water through the pipes.
3. Possibility to choose a model with expansion tank. With its help inside the heating system will occur automatic adjustment pressure.
4. Ariston equips its equipment various types ignition. It can be automatic, which will greatly facilitate the life of the owner of a particular boiler. Otherwise, each time the unit is started, a person will need to press a special button.

What are the advantages of Ariston gas boilers

Recently, the popularity of the Ariston brand has increased significantly due to high-quality gas boilers, and this is not in vain. operates silently and consumes as little fuel as possible. This will allow the owners of the unit to save on utility bills and, at the same time, provide home comfort and warmth.

The client will receive a high-quality device that provides round-the-clock water supply and heating of the house, even with a large area of ​​​​up to 500 square meters. Also, do not forget about the durability of the service of each boiler. The terms indicated in the guarantee are much more modest than they actually turn out to be. In terms of dimensions, the equipment is much more compact than other brands, which means that it can be installed absolutely anywhere, even in a small apartment with limited space.

Specifications

Almost all gas boilers from the Ariston brand have a power of 15 to 30 kW. Thus, each client will be able to choose the necessary indicators for the size of his apartment or house. It is also worth noting other distinctive characteristics of such gas equipment:

• with maximum efficiency, boilers have a high level of efficiency;
• all wall-mounted boilers have Russian instructions and designations on the equipment itself, so citizens do not have problems with controlling the unit;
• most models from this manufacturer are able to perfectly cope with water in the system and low pressure;
• special attention to this equipment should be given to those people in whose houses power surges often occur. Ariston boilers can easily cope with such jumps in the network;
• All models are very easy to operate. To start using the boiler, you do not need to study the instructions for a long time, all the features of operation are intuitive and accessible even for those who install such a unit for the first time.

In some cases, the boiler cannot simultaneously heat water and provide sufficient space heating, this applies to budget models. In this case, a person needs to think about installing an additional boiler.

Note! If we talk about expensive units, they have a special display that shows different characteristics, including the temperature inside the boiler and outside. This is very convenient in terms of introducing the necessary characteristics for the correct operation of the equipment.

Operating instructions for gas boilers Ariston

Before purchasing an Ariston gas boiler, you need to understand that if the buyer does not understand its installation, it is better to contact experienced specialists and entrust all the work to them. After all, even with the most detailed instructions, it is not a fact that the case will end successfully. In this case, there is every chance of damaging the equipment, after which you will have to call repairmen, and this will result in additional costs.

It is very important to keep children away from the equipment. To do this, after, it is necessary to have a conversation with them and explain in an accessible language that nothing can be twisted and put on the unit, only an adult should do this. If the family leaves, for example, on vacation, after the boiler is turned off, it is also necessary to shut off all pipes for the supply of gas and water. Only after that the equipment is disconnected from the network.

If a display is provided on any model, all indicators that it displays must be strictly controlled. It can display malfunctions or deviations from normal operation that occurred during the heating process.
