4. Boiler description
4.1. Boiler construction
VIADRUS CLEO wall boiler with water flow heating is equipped with a copper heat exchanger the whole surface of which is protected by a silicone paint based on aluminium with a resistance up to 350°C. These exchangers have separated systems for HSW heating and the heating system. A big advantage of the heat exchangers is that they save space and weight. The maximum working pressure for CH circuit is 3 bar at the working temperature of 85 °C and 6 bar for HSW preparation at the working temperature of 85 °C. Minimum working pressure is 1bar. The heat exchanger is positioned in the upper part of the combustion chamber an automatic bleeder valve is mounted on it, a part of which ends above the combustion chamber. Due to the minimum loss caused by the thermal transmission it is necessary to keep the surface of heat exchanger
lamellae clean.
The gas burner has an advanced modular construction and is made of stainless steel. It is positioned in the lower part of combustion chamber and electrodes are mounted on it, where one of them is the ignition electrode and another one is the ionisation electrode. The combustion chamber is made of aluminised steel plate with an internal thermal insulation. Above the combustion chamber (in VIADRUS CLEO T design) there is positioned the flue gases collector on which there is mounted a flue gases outlet ventilator. This ventilator by means of silicon hoses is connected to the differential pressure switch ( manostat ). In VIADRUS CLEO K design above the combustion chamber there is installed the draught diverter on which there is mounted the flue gases thermostat (surface sensor).
In the upper part of the heat exchanger there are installed the thermal sensors for heating system and HSW.
The internal water circuit in the boiler is made of copper tubes. The closing chamber at VIADRUS CLEO T design is made of aluminised sheet. The openings in this closing chamber are sealed by means of silicone bushings. On HSW inlet there is installed the water flow sensor.
This boiler in both designs is equipped with automatic and gradual output control. The main control element of this boiler is the modular electronic board equipped with a microprocessor which evaluates the conditions and values of sensors and issues the commands to the gas valve , ignition electronics and circulation
6
pump. On the internal heating water outlet there is installed an emergency thermostat , a pressure switch and a clack-valve of the manometer for signalling the pressure in heating system.
The emergency thermostat will shut down the wall boiler once the temperature has exceeded 95°C. The pressure switch will shut down the wall boiler once the pressure in heating system has dropped below 0,8 bar.
Then in the boiler at the heating water input into the boiler there is installed a safety valve. In the by-bass between HSW inlet and heating water inlet there is installed a ball valve which serves for heating system filling with water. In the rear part of the boiler there is installed an expansion tank of 8 l volume.

4.2. Control elements
Boiler control front panel
The thermometer measures the outlet water to the central heating. The manometer measures the pressure in central heating. By means of a button for setting the heating temperature the user sets the heating water in the system being heated in the range from 35 to 85 °C. The recommended range is from 55 to 85 °C. The button for
HSW temperature setting is by user set to the required hot service water outlet temperature ranging from 35 to
60°C. The emergency status signalisation signals the boiler status when the electronics does not manage to light
(like due to the gas supply interruption). The boiler is returned into the „boiler in operation” position by means of a position switch. “Boiler in operation “ signalisation signals the boiler in operation regime.
The boiler position switch positions are as follows :
- Boiler switched off
- summer operation
(HSW generation is in operation)
- winter operation
( the central heating plus HSW generation are in operation)
- failure de-blocking ( reset)
- service function

4.2.1. Integrated control system for boiler type AM 56 –IMS 02 code 16 562
Description :
The control automatics of AM 56 – IMS 02 type for suspended boilers with HSW flow heating, with a double heat exchanger and an automatic ignition.
The control function includes the flame ignition, its control and a continuous modulation. The automatics has two functional units:
1. burner control unit ( ACCF)
2. control unit and flame modulation ( GMF)
10
1. Burner control unit – ignition and ionisation (ACCF)
Electronic device for flame operation and control, for a direct burner ignition by means of a sparkle induced by the electric discharge and monitoring of flame presence by means of ionisation phenomenon.
Working sequences
By making the demand on heating contacts there is started the auto-test phase testing the flame amplifier and the parts related to a safe function securing the safety and resulting in ignition sequence start prevention if a failure appears on these elements.
At the end of the auto-test there starts the safety time during which the voltage is brought to the ignition device and to the gas valve output.
As soon as the burner is lit and is signalled by the flame presence there is switched off the sparkling and the boiler operation starts according to the selected regime.
By undoing the requirement contacts the gas valve gets closed and the device is automatically brought into the waiting status.
If the boiler does not light during the safety ignition, the device switches over into the failure condition with an automatic reset, there is disconnected the voltage from gas valve outlet and from the ignition unit.
The failure status is detected by the GMF unit signalising the failure.

- Setting of burner output in the phase of heating by means of a trimmer on the board.
- The type of gas selection can be done by means of JP1 jumper.
Boiler operation
HSW regime
As soon as at the HSW requirement the HSW flow exceeds 3l/min the pump gets blocked. The relay switches on the requirement and brings the voltage to the automatics. Approximately within 2 seconds after the other gas valve opening (the gradual start phase) the PID type flame modulation phase starts and continues until the correct HSW temperature achievement. If the temperature still keeps growing and achieves the switching temperature the burner switches off. The HSW regime phase is terminated if the HSW flow has dropped below 2,5 l/min. If in the heating regime the temperature is set above 55°C at the HSW flow below 3 l / min, the set heating temperature will be limited by 50°C in order to prevent the deposits creation in the heat exchanger secondary circuit If the HSW outlet temperature has achieved 70°C the burner switches off. After the demand on HSW termination the pump starts working in order to reduce the calcium deposits creation. The pump after running time keeps changing between 0,4 and 2 seconds depending on the temperature found out in the heating circuit at the time of HSW requirement. In case of parallel requirements the HSW regime takes precedence over the central heating. If the J5 jumper is positioned in ON position, the pump after running time is always 2 seconds at the end of HSW requirement.
Heating regime
The heating regime starts when the space thermostat has issued the demand on heating and the position switch is in winter position. There are activated the pump and the ventilator and after having checked the air flow there is activated the burner control unit. Approximately two seconds after the gas valve opening ( the gradual start phase) the burner output gets to the minimum set value and during 100 seconds it achieves the maximum output . As soon as the flame modulation point has been achieved the start function gets stopped and the control follows PID till the set heating water temperature achievement. In case that the water exceeds the set temperature by 51°C the burner switches off. It repeatedly lights up 5°C below the set temperature if the time of protection against a frequent switching has expired. The frequent switching function is terminated if the indoor thermostat contacts (or the WINTER regime contacts on the position switch) are undone and made or in case of HSW requirement. If the JP4 jumper is set to ON position the temperatures range is reduced to the value suitable for floor heating.
Note. There must be always used the equipment limiting the high temperature ( for the floor heating protection).
Pump control and circulation
The pump switches on at the moment of heating or HSW requirement At the end of every heating requirement the pump keeps working for 180 seconds. In case that after the working period there occurs a failure in the heating regime the pump keeps working for the whole time as an after-running into the heating system.

Pump blocking function
After 24 hours of inactivity the pump is activated for 150 seconds. After the electricity supply interruption there appears the first cycle against the pump blocking after the 3 rd hour of inactivity.
Antifreeze function
In case that the temperature sensor in the primary circuit has detected the temperature decrease below 8°C the pump gets activated and the burner starts running with the minimum output. This lasts till 35°C temperature has been achieved when the antifreeze function ends up. The antifreeze function is still active even if the position switch is in “SUMMER” position and the emergency ( stand – by) regime. If the boiler is in a failure only the pump is activated.
Ventilator operation and the air flow control
In case of ignition demand there is first of all checked the air flow absence. If this test result is positive the ventilator starts working.
As soon as the air flow is secured the relay enables the automatics to switch on the burner.
If the air flow absence is detected for 15 seconds though the ventilator is activated there is indicated a failure and the system waits for signal indicating the air presence.
After every burner switching off the ventilator keeps running for 20 seconds.
If the primary circuit temperature has achieved 105°C there is activated the pump which runs as long as the temperature has dropped below pod 100°C.
VIADRUS CLEO K version
In this version with an open combustion chamber in case of heat requirements there first of all is activated the pump and the water flow presence is verified and afterwards the burner control unit is activated.
If the flue gases thermostat switches off a failure is signalled and for 30 minutes no repeated ignition is possible. This time interval can be reset by switching off and switching on the position switch.
13
BERTELLI automatics function
If there is a short-circuited space thermostat, the pump keeps running ( though the boiler is switched off). The pump runs because the boiler still receives the demand on heating and drives the water into the system.
Even if the boiler is switched off by the space thermostat the pumps runs after that for 180 seconds..
Parasitic flame ( the ionisation detects the flame before the ignition) can happen at the situations like the gas valve failure. When it is asked to light the boiler the ignition does not start. The upper red LED is blinking , the middle green LED is alight and the lower red LED is off. After the removal of fault the boiler is in the normal regime.
JP 1 Natural gas
OFF ON
JP 3 Anti-cycling function: between switching propane – butane
It is switched on immediately after the off and switching on by CH water temperature it is waited for 180 seconds.
CH water temperature has dropped below the set value.
JP 4 Water is heated according to the setting The floor heating, maximum CH temperature = 40°C
JP 5 After the HSW heating has been switched off the pump runs for 0,4 – 2 seconds . It depends on CH water temperature.
The pump runs always for 2 seconds after the HSW termination.
Anti-cyclic function - JP3 is inactivated, it functions in the way that if the water temperature in CH has switched off the boiler and this temperature drops quickly the boiler will not start immediately. This is the waiting time lasting for 180 seconds. Only after this time has passed the normal ignition comes through. This function prevents the boiler from working only in the short circuited current and keeping switching on and switching off (according to CH temperature). If during this time there is a HSW requirement the ignition will be immediate.
JP2 short circuit will disqualify this function . Then the boiler responds continually, lights up immediately after
CH water temperature has dropped ( if the space thermostat is switched on).
The pump after-running after HSW requirement termination - if JP5 is disconnected , by the automatics the
CH water temperature after HSW heating termination is evaluated and depending on this temperature the pump starts up for the time between 0,4 and 2 s. (higher temperature = long time) in order to cool down the heat exchanger. If JP5 is connected the pump after running time is always 2 seconds (it does not depend on the temperature).

5.2 Installation conditions
Only a firm authorized for boilers installation is allowed to install VIADRUS CLEO gas boiler on the basis of the designer ´s approved documentation. Before the installation the assembly firm is obliged to make a correct boiler choice with regard to its functional characteristics and required parameters.
The boiler has IP 41 protection which guarantees the resistance against the vertically dripping water.
Therefore it can be installed in bathrooms in zone 3 ( in the distance min. 60 cm from the edge of the bath-tub or the shower enclosure). The room in which the boiler is installed must have the air temperature between +5 and
+35°C with a relative humidity up to 80%. The objects must not be neared to the boiler contour within the distance shorter than:
- 100 mm in case they are made of materials combustible with difficulty or moderately combustible
- 200 mm in case they are made of easily combustible materials
The shortest distance between the appliances and the combustible materials in the direction of the main radiation is 50 mm and in other directions this distance is 20mm.
The first commissioning and boiler operators training must be done by contracting service partner of the factory. At the supply gas piping in front of the boiler there must be installed the manual gas stop valve which must be freely admissible ( is not included in boiler supply). The boiler connection to the heating system is carried out by means of G 3/4“ threaded connections. The HSW and gas connections are carried out by means of G 1/2“threaded connections.
Before the boiler installation it is necessary to make sure that the selected place corresponds to the demands on combustion gases exhaustion positioning and that the minimum distances are observed before the commissioning process. Because this is a rapid heating boiler equipped with its own pump it can be connected both to the gravity system and to the closed system of heating system distribution. For the new distributions we recommend the heating bodies of a low volume and distributions in the minimum possible dimensions with regard to a rapid system temperature growth and a big system flexibility. The boiler connection to the heated water distribution and HSW distribution systems must be carried out in the way making sure that the boiler connection outlets are not strained.
Before the boiler connection to the heating system this heating system must be properly flushed out in order to remove possible minor impurities. The heating system must be equipped with a suitable filter. For the utilization of maximum heat exchanger output it is necessary to provide a minimum system overpressure of 1 bar in order to adhere to the correct functions and the heating system. On HSW inlet into the boiler it is necessary to install the magnetic or electromagnetic water treatment which isn’t a part of boiler. The boiler must be positioned in a way making sure that the boiler operating condition( combustion air inlet and flue gases exhaustion) will be ensured.
21
Fig. No. 7 Boiler main dimensions
5.3. Positioning
The boiler positioning must correspond to the project documentation. The boiler is positioned in a way making sure that the necessary operating conditions are ensured. (VIADRUS CLEO K ,the boiler with open combustion chamber or VIADRUS CLEO T, the boiler with closed combustion chamber ), this with regard to the volume of brought combustion air and the flue gases exhaustion. At the sides of the boiler an access of minimum 0,2 m and in front of the boiler an access of minimum 1 m must be ensured for installation and service. The boiler must be installed min. 0,1 m above the floor. VIADRUS CLEO K boiler design has an open combustion chamber. The combustion air is taken directly from the room where the boiler is installed.
The room can either be ventilated directly through the ventilation openings interconnected with outdoor environment or indirectly from the neighbouring room. In case of an indirect air suction the neighbouring room , from which the air is sucked must not be a bedroom, garage, a room with a risk of fire or combustible materials storeroom.

6. Commissioning
6.1 Connection to the system
6.1.1.Connection to the heating system and filling with water
VIADRUS CLEO boiler is designated for heating systems with a forced circulation . The water flow speed can be set by the selection of pump revolutions switch. The heating system must be thoroughly flushed out before filling with water in order to wash out al impurities that can be deposited in distribution pipes or heating bodies and can result in damaging the pump. Water for filling of boilers and heating system must be clear and colourless, with no suspended substances, oil and aggressive chemicals. Its hardness must correspond to ČSN 07 7401:1992 and it is necessary to treat water in case its hardness is unsuitable . Even heating the water of a higher hardness several times does not prevent the soils from getting precipitated on the boiler drum walls. Precipitation of 1 mm calcite reduces at a given point the passage of heat from the metal to water by 10%. The circulating and filling water parameters must correspond to:
Maximum permissible values of heating water according to ČSN 07 7401:1992
Total Fe + Mn concentration (mg/l) 3*
*recommended value
During the heating season it is necessary to keep a constant volume of heating water in heating system and be particular about bleeding the heating system. Water from the boilers and heating system must never be discharged or taken for usage except in cases of emergency like repairs etc. Water discharge and filling with new water increases the danger of corrosion and scale development. In case we have to refill the
heating system with water we only do this operation when boiler is cold in order to prevent its sections from getting broken.
In front of the heating system at the heating system inlet there must be installed a filter. We recommend a brass filter with a side cleaning (it is not a part of boiler delivery) . In front of the filter and other boiler flanges connection there must be installed the ball valves (they are not a part of boiler delivery). This filter must be cleaned at least once a year. A clogged filter might be a source of boiler noisiness. The safety valve outlet must be connected to the waste piping. The guarantee does not refer to the heat exchanger or pump
clogging by the impurities from the system.
We don’t recommend to exceed the 3,5mval/l water hardness in heating system. The expansion tank volume is 8 litres. This volume is sufficient for approx. 150 l water in heating system. If it is required by the heating system it is necessary to install another expansion tank. It is recommended the temperature difference of 15 – 20°C between the heating system outlet and inlet water.
When filling the boiler with water the system must be disconnected from the el. network. The bleeder valve is installed both on the boiler and the heating system and must be open. The system is pressurized to the required approx. 1 bar pressure and then it is vented again. Afterwards the expansion tank is adjusted; its internal pressure must be by 0,1 bar lower than the pressure in the heating system. At the heating system inlet there is recommended a filter to be used for filling with water.
The heating system must have a sufficient number of ventilation points. On the lowest level of the heating system there must be installed a discharge valve.
The connection to the water-supply network and HSW take off points are also recommended to be carried out through the ball valves. The maximum permissible HSW overpressure from the water-supply network is 6 bar. At the HSW inlet into the boiler there must be built-in a magnetic water treatment. The
guarantee does not refer to the heat exchanger or pump clogging by scale.

6.1.2. Gas connection
Before the gas pipes connection to the boiler the gas pipes must be tested and revised. All gas joints after their connection to the boiler must be tested using a gas detector or foaming solution. Maximum natural gas inlet pressure is 20 mbar. The gas pipes threaded joints must never be strained by additional forces.
6.1.3.Connection to the electricity network
The boiler is equipped with a movable three-core cable. It is connected to the network socket positioned maximum 1 m from the boiler. The socket must meet the protection by zeroing or grounding and must have a phase conductor installed in the left plug contact when the earth-plug is upward. The boiler doesn’t work if there is a different connection. It is forbidden to use the adaptors and extension cords. Installation of a socket, connection of an indoor thermostat and the service of boiler electric part can only be done by a person holding an adequate authorization for a professional electrotechnic qualification.
6.1.4. Connection of an space thermostat ( regulator)
The space thermostat is not a part of boiler. At the customer ´s request it is possible to connect the space thermostat into the boiler. The voltage for space thermostat switching contacts is 24 V. The space thermostat connection to the boiler is shown in the wiring diagram see Fig.No.5,6. The terminals for the space thermostat connection into the boiler are by the manufacturer interconnected through a jumper . This jumper must be removed when the space thermostat is connected to the terminals.
6.1.5 Smoke outlet
6.1.5.1. Connection to a chimney ( VIADRUS CLEO K)
VIADRUS CLEO K, the wall gas boiler is connected to the chimney through the neck / socket φ 130mm . The connection to the chimney according to the valid regulations must have the 3% chimney gradient in direction to the boiler. The flue gases reflux fuse ( flue gases thermostat ) must not be put out of operation. It is forbidden to interfere with the flue gases reflux fuse in an unskilled way. For the flue gases reflux fuse installation and the exchange of its faulty parts there only can be used the original parts delivered by the manufacturer. Above the boiler there must be kept a straight minimum 0,3 – 0,5 m long section.
6.1.5.2. Connection to the coaxial tubes ( VIADRUS CLEO T)
Flue gases outlet and the combustion air inlet are carried out through a doubled piping delivered by the manufacturer. This piping can be ordered in a sufficient need according to the project( horizontal or vertical flue gases outlet) incl. the sealing gaskets, passages trough the roof etc.
The conditions for the flue gases outlet outfall on the external wall :
- the outfall must protrude min. 150mm out of the building external wall
- min. height above the ground into the area inaccessible for public is 1 m
- min. height above the ground into the area accessible for public is 2 m
- the outfall must not be in an explosive and combustible environment
- if in the area in direction upwards there are combustible materials on the building it is necessary to keep a vertical 1,5 m distance from the outfall
The maximum flue gases outfall maximum lengths permitted by the manufacturer for VIADRUS CLEO T version:
- horizontal smoke outlet 3 m – measured from the elbow up to the outfall on the façade
- vertical smoke outlet is 2,7 m – measured from the boiler to the lower edge of the roof superstructure

7. Boiler operation by user
The boiler can only be operated in compliance with the instructions stated in this manual. Except the operating activities the operator must not carry out any repairs, modifications on the boiler neither take apart and clean the boiler internal parts. The boiler can only be operated by persons above 18 years old. When the house is abandoned in winter ( like a leisure amenity) it is necessary to ensure an adequate supervision by an instructed person. As soon there is a risk of combustible( explosive) gases or vapours access to the boiler ( like at PVC gluing etc.) the boiler must be put out of operation. The user is obliged to care about the correct boiler use in compliance with this manual, which conditions the guarantee. At the boiler commissioning the service worker
is obliged to acquaint the user with the boiler operation. The user by his signature in the guarantee certificate confirms that he was acquainted with boiler operation.
The boiler itself is in operation secured against the dangerous conditions. But it cannot prevent from the failures the reason of which isn’t included in the boiler mechanism. It is necessary that the boiler operators after commissioning inspect the boiler every third day and check whether :
- the system is filled with water and the water does not leak out from the system
- whether in the environment the flue gases or gas cannot be smelt
- whether there is detected the pressure drop and it is necessary to fill-up the cold heating system with water.
If the same operation interruption keeps repeating it is necessary to call the service engineer.
The detected failures must be immediately reported to the service worker. The detected defects must be rectified immediately.

HSW, this function is interrupted .
Behaviour in case of a failure:
In case of a flame simulation the ignition is prevented.
Note: If GMF unit at the flame control detects the flame simulation, it reports the defect and if the simulation lasts for longer than 15 seconds the demand on heat is stopped (the heat is switched off by the relay related to the heat demand) and a new ignition can only be attempted after the system reset via the regimes position switch.
- Cycling repetition in case of flame failure while running
- The failure condition which can be eliminated by switching off and switching on the main electricity supply in case of the flame absence
Note: GMF unit distinguishes a fault caused by ignition failure and the fault caused by switching off because the maximum temperature has been exceeded ; it indicates the relevant fault and switches off the relay unit related to the heat demand. A new ignition can only be attempted after the system reset via the regimes position switch.
