To enable the Anti-Legionella Function it is necessary to set parameter P23, within the "TECHNICAL MENU", to ON. To program the function it is necessary to access the "Legionella" menu via the path "USER MENU" "DOMESTIC HOT WATER" "Legionella".

In this menu it is possible to set the following options:

• Anti-Legionella day. Defines the day of the week during which the function will be activated. The function can only be activated once a week.
• Anti-Legendella time of day. Defines the start time of the function.
• Anti-Legionella duration. Defines the duration (in minutes) of the function.
• Anti-Legionella Adjustment Temp. Defines the DHW Adjustment temperature during the function.

ATTENTION In ECO m

In ECO mode the function is not active.
- The Anti-Legionella Function will only be active if the boiler is set to "Automatic" mode" (O) and only in the time bands set to ON or to "Reduced temperature"
Otherwise, in the time bands set to OFF, the function will not be activated, even if set.
- In vacation mode ( ) the Anti-Legionella Function is active.
- If the Anti-Legionella Function is not carried out correctly, the message shown in fig. 27 is displayed. Even in the presence of this message, the boiler will continue to operate correctly.

fig. 27- Message Anti-legionella function not completed

The temperature set via the "Anti-Legionella Adjustment Temp." menu must NOT be higher than the maximum DHW adjustment temperature set via parameter P19 within the TECHNICAL MENU.

If a circulating pump is installed in the system, for water circulation during the Anti-Legionella Function, parameter b08 must be set to 1. In this way the contact between terminals 9-10 (ref. 300 - fig. 95, fig. 96 and fig. 97) closes when the function is activated.

Holiday Function

Access the "HOLIDAY FUNCTION" menu through the path "USER MENU HOLIDAY FUNCTION" to set:

• Holiday start date.

The display can activate two types of icons:

• The Holiday function is programmed but not yet active.
• The Holiday function is in progress. The boiler will behave as if Summer mode and Economy mode were active (with optional hot water tank installed).

The frost protection and Legionella functions will remain active (if activated).

Service Intervention Date

This informs when the alert of programmed maintenance by the technician will be activated. It does not represent an alarm or a fault but just a notice. After that date, whenever the Main menu is accessed, the boiler will activate a screen indicating that programmed maintenance is due.

Service Information

This information shows the telephone number to contact in case of assistance (if programmed by the technician).

Room temperature adjustment (with optional room thermostat)

Using the room thermostat, set the temperature required in the rooms.

Room temperature adjustment (with optional remote timer control)

Using the remote timer control, set the temperature desired in the rooms. The boiler unit will set the system water according to the required room temperature. For information on the remote timer control, please refer to its user's manual.

Sliding Temperature

When the external probe (optional) is installed, the relevant external temperature symbol is activated on the control panel display. The boiler control system works with "Sliding Temperature". In this mode, the heating system temperature is regulated according to weather conditions, to ensure high comfort and energy efficiency throughout the year. In particular, as the outside temperature increases the system flow temperature decreases according to a specific "compensation curve".

With Sliding Temperature adjustment, the "Heating adjustment" temperature becomes the maximum system flow temperature. It is advisable to set a maximum value to allow system adjustment throughout its useful operating range.

The boiler must be adjusted at the time of installation by qualified personnel. The user can still make further adjustments for better comfort.

Compensation curve and curve offset

Access the Sliding Temperature menu. Adjust the desired curve from 1 to 10 according to the characteristic (fig. 30) via the parameter "Curve1" and confirm with the OK button.

By setting the curve to 0, the sliding temperature adjustment is disabled.

fig. 28- Compensation curve

Adjust the parallel offset of the curves from 20 to 60^ (fig. 31), via the parameter "Offset1" and confirm with the OK button.

fig. 29- Parallel curve offset

If the room temperature is lower than the desired value, it is advisable to set a higher order curve and vice versa. Proceed by increasing or decreasing in steps of one and check the result in the room.

fig. 30- Compensation curves

fig. 31- Example of compensation parallel curve offset

This parameter is used only if the time programming has been activated. See *** 'Time programming' on page 147 ***

Outside Temperature Heating OFF

Access the "Out Temp Heat Off' to activate the function: between 7^ and 30^

If activated, this function will deactivate the heating demand whenever the temperature measured by the external probe is higher than the programmed value.

The heating demand will be reactivated as soon as the temperature measured by the external probe is lower than the programmed value.

Adjustments from remote timer control

If the boiler is connected to the Remote Timer Control (optional), the previously described adjustments are managed as described in table 1.

2. Installation

2.1 General Instructions

THE BOILER MUST ONLY BE INSTALLED BY QUALIFIED PERSONNEL, IN COMPLIANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE CURRENT PROVISIONS OF LAW, THE NATIONAL AND LOCAL REGULATIONS, AND THE RULES OF PROPER WORKMANSHIP.

For Switzerland, the following installation regulations and directives must be applied:

• SVGW - gas principles G1: installation Gas
• EKAS - Form. 1942: liquid gas directive, part 2
• Cantonal laws and regulations (e.g. fire safety regulations)

OPERAs is a heat generator arranged to operate alone or in cascade (bank).

FERROLI supplies on request all the hydraulic accessories and smoke manifolds for the connection of 2 or 3 units in cascade in configurations of 70 + 70kW to 450 + 450 + 450kW .

When OPERA generators are installed in cascade with the accessories foreseen by FERROLI, all the requirements of current laws and regulations applicable to such "equivalent" generator of total thermal capacity must be met. In particular the place of installation, safety devices and fume exhaust system must be adequate for the total heating capacity of the bank of units. The instructions given in this manual concern both the single unit and the connection in cascade. For further information regarding installation of the generators in cascade, refer to the specific manual supplied with the cascade connection kits.

The boiler electronics are equipped with management functions for a cascade of up to 6 units. To create cascade systems with more than three units without using the accessories foreseen by FERROLI, suitably sized hydraulic/gas manifolds must be arranged, complete with all the safety devices required by current regulations, as well as individual fume exhausts or fume manifolds appropriately sized by a qualified technician.

2.2 Place of installation

The generator must be installed in a suitable room with ventilation openings towards the outside in conformity with current regulations. If there are several burners or exhausters that can work together in the same room, the ventilation openings must be sized for simultaneous operation of all the units. The place of installation must be free of flammable materials or objects, corrosive gases, powders or volatile substances. The room must be dry and not exposed to rain, snow or frost. For positioning, leave sufficient room around the unit for normal maintenance operations. In particular, check that the burner door can open freely.

2.3 Plumbing connections

The heating capacity of the unit must be previously established by calculating the building's heat requirement according to current regulations. The system must be provided with all the components for correct and regular operation. In particular, provide for all the protection and safety devices required by current regulations for the complete modular generator. They must be installed on the hot water circuit flow piping, immediately after the last module, within a distance of not more than 0.5m and with no shutoff devices in between. The unit is not supplied with an expansion tank or safety valve; their connection must therefore be carried out by the Installer.

This unit can operate correctly also with a minimum flow rate of 0 l/h and does not require post-circulation to eliminate the thermal inertia. With reference to par. "3.3. R3F file R edition 2009" the post-circulation time prescribed by the manufacturer is therefore equal to 0 seconds.

The safety valve outlet must be connected to a funnel or collection pipe to prevent water spurting onto the floor in case of overpressure in the heating circuit. Otherwise, if the discharge valve cuts in and floods the room, the boiler manufacturer cannot be held liable.

Do not use the water system pipes to ground electrical appliances.

Before installation, flush all the pipes of the system thoroughly to remove any residuals or impurities that could affect proper operation of the unit. Use chemical conditioners suitable for the purpose; i.e. able to remove from the walls and bottom of the pipes and the various components of the system, sludge, metal

oxides and, in low temperature systems, also biomass, with just the circulation of the water, with system hot and/or cold. The products used must not be corrosive and/or aggressive for metals and plastics and must not significantly alter the natural pH of the water.

Also, a filter must be installed on the system return piping to prevent impurities or sludge from the system clogging and damaging the heat generators.

The filter must be installed when replacing generators in existing systems. The manufacturer declines any liability for damage caused to the generator by failure to install or inadequate installation of this filter.

Carry out the relevant connections according to the diagram in sec. 4.1 and the symbols on the unit.

Table 2- SIZE OF CONNECTIONS

MODEL 70 125			160 220	320 450
System flow 1" 1/4 threaded 1" 1/4 threaded 2"	threaded DN65 flanged DN65 flanged

Gas inlet 3/4" threaded 1" threaded 1"	1" 1/4 threaded 1"	1/2 threaded

In case of installation in bank, the water circuit of each boiler must be fitted with a motor-operated shutoff valve (controlled by the unit, see wiring diagram fig. 95) that prevents reverse circulation with the boiler not working.

A single safety valve must also be provided for each boiler in accordance with the requirements of "file R".

The following optional kits are available for this purpose:

052000X0 - MOTOR-OPERATED BUTTERFLY VALVE DN50

052001X0 - MOTOR-OPERATED BUTTERFLY VALVE DN65

If the distribution system adjustment is independent of the electronics of the generators, the creation of a bypass between the flow manifold and that of the system return is advisable in order to protect the circulating pumps.

System water characteristics

Before installing the OPERA generator, the new or existing system must be properly cleaned in order to eliminate installation residues, solvents, sludge and contaminants in general that may compromise the effectiveness of the protective conditioning treatments. Use neutral cleaning products that do not attack metals, rubber and plastic parts of the generator/system. Empty, wash and recharge the system in compliance with the following instructions. A dirty system will not guarantee the life of the generator over time, even with the use of protective conditioners.

OPERA boilers are suitable for installation in heating systems with non-significant entry of oxygen (ref. systems "case I" EN14868). A physical separator (e.g. plate heat exchanger) must be provided in systems with continuous entry of oxygen (e.g. underfloor systems without anti-diffusion pipes or open vessel), or frequent (frequent water replenishment).

The water in a heating system must be treated in compliance with the laws and regulations in force, have the characteristics required by UNI 8065, and comply with the provisions of EN14868 (protection of metallic materials against corrosion).

The filling water (first filling and subsequent replenishments) must be potable, clear, with hardness under the values indicated in the table below and treated and conditioned with chemical conditioners declared suitable by the maker (see following list), in order to prevent encrustations, corrosive or aggressive phenomena on the metals and plastics of the generator and system, the formation of gas, and the proliferation of bacterial or microbial masses in low temperature systems.

The water contained in the system, as well as the replenishment water, must be checked periodically (at every start-up of the system, after any non-scheduled intervention such as, for example, replacement of the generator or other system components, as well as at least once a year during mandatory routine maintenance operations as required by UNI 8065). The water must have a clear appearance and respect the limits given in the following table.

	EXISTING SYSTEM NEW SYSTEM
WATER PARAMETER
Total filling water hardness (°f) <10 <10
Total system water hardness (°f) <15 <10
PH 7 < Ph < 8.5
Copper Cu (mg/l) Cu < 0.5 mg/l
Iron Fe (mg/l) Fe < 0.5 mg/l
Chlorides (mg/l) Cl < 50 mg/l
Conductivity (μS/cm) < 600 μS/cm*
Sulfates < 100 mg/l
Nitrates < 100 mg/l

• In the presence of conditioners, the limit increases to 1200 S/cm .
  In case of differing values or difficult verification of values with conventional analysis/testing procedures, contact the company for additional evaluations. The conditions of the feed water to be treated can vary even significantly depending on the geographical areas where the systems are located.
  Chemical conditioners deoxygenating, anti-scaling, corrosion inhibiting, anti-bacterial, anti-algae, frost protection, PH correction products, etc., must also be suitable for the materials of the generator and system. They must be put in the system respecting the quantity indicated by the supplier of the chemical product and verified in their concentration.

A chemical conditioner in insufficient concentration will not be able to ensure the required protection.

Always check the product concentration each time it is added and cyclically, at least once a year, using qualified technical personnel such as our authorized technical assistance network.

2.4 Gas connection

Before making the connection, make sure the unit is arranged for operation with the type of fuel available and carefully clean all the pipes of the gas system to remove any residues that could affect proper functioning of the boiler.

The gas must be connected to the relevant connection (see fig. 74, fig. 77, fig. 80, fig. 81 and fig. 84) in conformity with the current regulations, using a continuous-surface stainless steel hose, placing a gas cock between the system and the boiler.

To allow easy opening of the burner door during periodic maintenance, the last section of the connection between the system and the unit must have a continuous-surface stainless steel hose.

fig. 53

Make sure that all gas connections are tight. The capacity of the gas meter must be sufficient for the simultaneous use of all units connected to it. The diameter of the gas pipe leaving the boiler is not decisive for choosing the diameter of the pipe between the unit and the meter; it must be chosen according to its length and pressure losses, in conformity with the current regulations.

Do not use the gas pipes to earth electrical appliances.

In case of connection in cascade, make sure to install a fuel shutoff valve externally with respect to the modules.

2.5 Electrical connections

Connection to the electrical grid

The unit's electrical safety is only guaranteed when correctly connected to an efficient earthing system executed according to current safety standards. Have the efficiency and suitability of the earthing system checked by professionally qualified personnel. The manufacturer is not responsible for any damage caused by failure to earth the system. Also make sure that the electrical system is adequate for the maximum power absorbed by the unit, as specified on the boiler dataplate.

The boiler is prewired and provided with a Y-cable and plug for connection to the electricity line. The connections to the grid must be made with a permanent connection and equipped with a bipolar switch whose contacts have a minimum opening of at least 3mm , interposing fuses of max. 3A between the boiler and the line. It is important to respect the polarities (LINE: brown wire / NEUTRAL: blue wire / EARTH: yellow-green wire) in making connections to the electrical line. During installation or when changing the power cable, the earth wire must be left 2cm longer than the others.

The user must never change the unit's power cable. If the cable gets damaged, switch off the unit and have it changed solely by professionally qualified personnel.

If changing the electric power cable, use solely "HAR H05 VV-F" 3 × 0.75 ~mm^2 cable with a maximum outside diameter of 8 ~mm .

Room thermostat (optional)

CAUTION: The room thermostat must have clean contacts. CONNECTING 230 V. TO THE TERMINALS OF THE ROOM THERMOSTAT WILL IRREPARABLY DAMAGE THE ELECTRONIC CARD.

When connecting a remote timer control or a timer switch, do not take the power supply for these devices from their cut-out contacts. Their power supply must be taken with a direct connection from the mains or with batteries, depending on the kind of device.

External probe (optional)

Connect the probe to its respective terminals. The maximum permissible length of the boiler - external probe connection electric cable is 50m . A common 2-core cable can be used. The external probe should preferably be installed on the North, North-West wall or on the wall with most of the main living room. The probe must never be exposed to the sun in the early morning, and in general, as far as possible, it must not receive direct solar radiation; if necessary, it must be protected. In any case, the probe must never be mounted near windows, doors, ventilation openings, flues or heat sources that could affect the reading.

fig. 54- Positioning of external probe not recommended

Accessing the electrical terminal block

The electrical terminal block is located in the back of the boiler. Make the electrical connections as shown in the wiring diagram on fig. 95 and run the cables through the special cable glands.

fig. 55-Electrical terminal block

Maximum applicable loads:

• Heating circulating pump: 230Vac 0.8A max, C@98p
  3-way valve: 230 Vac, 0.8 A max, G0 for max 1 minute, 0.4 A continuous
• Alarm: 230 Vac, 0.8 A max, ∈0.6 φ

1. Carry out all the electrical connections (terminals 1 to 30) on module no.1
2. On the remaining modules, connect only the power supply and, if necessary, the contacts relevant to: burner on (300), fault contact (301) and remote reset input (302).

Remove the jumper relevant to: Room Thermostat (72)/Remote Timer Control (139).

1. Switch on the power to the entire cascade

2. After the "FH" procedure, check correct operation of the cascade:

3. Module 1: MASTER icon

4. Module 2: SLAVE icon
5. Module 3: SLAVE icon

If this does not occur, disconnect the power and check the wiring in fig. 56.

Settings

All adjustments must be made on all the modules, whereas Time Programming must be set only on Module 1.

Possible faults

If the electrical connection of a module is disconnected for any reason, module 1 will activate fault F70.

If the electrical connection of a module is disconnected for any reason, the next module will activate fault F71.

2.6 Flue connection

Important

The unit is a B23-type with combustion air drawn from the place of installation, and fume exhaust by means of a fan (operation with flue pressurised), and must be connected to one of the discharge systems indicated below. Before proceeding with installation, check and carefully comply with the local regulations and provisions. Also, comply with the provisions on the positioning of wall and/or roof terminals and the minimum distances from windows, walls, ventilation openings, etc.

Manifold, ducts and flue must be suitably sized, designed and made in compliance with the current regulations. They must be made of suitable materials, i.e. resistant to heat and corrosion, smooth on the inside and tight. In particular, joints must be condensate proof. Also, provide for adequate condensate drainage points, connected to a trap to prevent the condensate formed in the flues from running into the generators.

Connection

To calculate the maximum length of the fume ducts, refer to the maximum available head indicated in table 5.

Before making the flue connection fill the condensate trap with approx. 0.5 liters of water through the flue connections.

fig. 57-Fume outlet

Table 5- Maximum flue pipe length

3.2 Commissioning

Checks to be done at first lighting, and after all maintenance operations that involved disconnection from the systems or work on safety devices or parts of the boiler:

Before lighting the boiler

• Open any on-off valves between the boiler and the systems.
• Check the tightness of the gas system, proceeding with caution and using a soap and water solution to detect any leaks in connections.
• Check correct prefilling of the expansion tank (ref. sec. 4.3).
• Fill the water system and make sure all air contained in the boiler and the system has been vented, by opening the air vent valve on the boiler and any vent valves on the system.
• Fill the condensate trap and check correct connection of the condensate elimination system.
• Make sure there are no water leaks in the system, DHW circuits, connections or boiler.
• Check correct connection of the electrical system and efficiency of the earthing system
• Make sure the gas pressure value for heating is that required.
• Make sure there are no flammable liquids or materials in the immediate vicinity of the boiler

IF THE ABOVE INSTRUCTIONS ARE NOT OBSERVED THERE MAY BE RISK OF SUFFOCATION OR POISONING DUE TO GAS OR FUMES ESCAPING; DANGER OF FIRE OR EXPLOSION. ALSO, THERE MAY BE A RISK OF ELECTRIC SHOCK OR FLOODING THE ROOM.

Checks during operation

• Turn the unit on as described in sec. 1.3.
• Make sure the fuel circuit and water systems are tight.
• Check the efficiency of the flue and air-fume ducts while the boiler is working.
• Check the correct tightness and functionality of the condensate elimination system and trap.
• Make sure the water is circulating properly between the boiler and the systems.
• Make sure the gas valve modulates correctly in the heating and domestic hot water production phases.
• Check proper boiler lighting by doing several tests, turning it on and off with the room thermostat or remote control.
• Using a combustion analyser connected to the boiler fume outlet, check that the CO _2 content in the fumes,with the boiler operating at max. and min. output, corresponds to that given in the technical data table for the corresponding type of gas.
• Make sure the fuel consumption indicated on the meter matches that given in the technical data table on sec. 4.3.
• Check the correct programming of the parameters and carry out any necessary customization (compensation curve, power, temperatures, etc.).

3.3 Maintenance

Periodical inspection

To ensure proper operation of the unit, it is necessary to have an annual inspection carried out by qualified personnel, providing for the following:

• heat exchanger check and cleaning with suitable products if dirty or clogged
• check and possible cleaning of burner (do not use chemical products or wire brushes)

IMPORTANT: after cleaning the burner, be sure to position it by aligning the flange joint weld with the center of the peephole hole (see fig. 67).

fig. 67 - Alignment of the burner

• check and cleaning of electrodes, which must be free of deposits and properly positioned
• seal and gasket check (burner, sealed chamber, etc.)
• check and cleaning of sludge remover filters and system filters
• check, cleaning and filling of condensate drain traps
• check of wiring, contacts, electrical actuators
• check and cleaning of generator air inlets and boiler room air intakes
• check and cleaning of fume evacuation duct-manifold-flue system.
• expansion tank check and prefilling
• check of correct and stable system water pressure, ensuring conformity with the required working pressure.

The use of automatic filling systems for reinstatement of operating conditions must provide for adequate treatment of the water (ref. *** 'System water characteristics' on page 155 ***)

check of heating system water chemical and physical parameters (ref. *** 'System water characteristics' on page 155 ***)
water and gas system tightness check
- check of correct and stable gas supply pressure to plant (20 mbar for operation with natural gas); any fluctuations or pressure drops below the declared value can create malfunctioning and stops with need for manual resetting.
- burner ignition and control and safety device check (gas valve, flowmeter, thermostats, etc.)
- circulating pump check, freeing when necessary
- fume analysis and check of combustion parameters

The casing, control panel and aesthetic parts of the boiler can be cleaned with a soft damp cloth, possibly soaked in soapy water. All abrasive detergents and solvents should be avoided.

Burner door opening

To access the burner observe the following instructions.

• Remove the cover and front panel (fig. 68).

3.4 Troubleshooting

Diagnostics

The boiler is equipped with an advanced self-diagnosis system. In case of a boiler fault, the display lights up indicating the fault code and, in case of cascade connection, the module number.

• There are faults that cause permanent shutdowns which can be reset by pressing the OK button for one second or with the RESET button on the remote timer control (optional) if installed. If the boiler fails to restart after resetting, it is necessary to eliminate the fault first.
• Other faults cause temporary shutdowns which are automatically reset as soon as the value returns within the boiler's normal working range.
