3. INSTALLATION

3.1 General Instructions

BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRESCRIPTIONS OF NATIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP.

3.2 Place of installation

This unit is an "open chamber" type and can only be installed and operated in permanently ventilated rooms. An insufficient flow of combustion air to the boiler will affect its normal operation and fume evacuation. Also, the fumes forming under these conditions are extremely harmful to health if dispersed in the domestic environment.

The unit is designed to operate in a partially protected place, with a minimum temperature of -5^ . If provided with the special antifreeze kit, it can be used with a minimum temperature down to -15^ . The boiler must be installed in a sheltered place, for instance under the slope of a roof, inside a balcony or in a protected recess.

The place of installation must be free of flammable materials, objects and dusts or corrosive gases.

The boiler is arranged for wall mounting and comes as standard with a hooking bracket. Wall fixing must ensure stable and effective support for the generator.

If the unit is enclosed in a cabinet or mounted alongside, there must be sufficient space for removing the casing and for normal maintenance activities

3.3 Plumbing connections

Important

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.

Before making the connection, check that the unit is arranged for operation with the type of fuel available and carefully clean all the system pipes.

Carry out the relevant connections according to the diagram in fig. 2.3 and the symbols on the unit.

Note: The unit is equipped with an internal bypass in the heating circuit.

Water system characteristics

In the presence of water harder than 25^ r (1^ = 10ppmCaCO_3) use suitably treated water in order to avoid possible scaling in the boiler.

Antifreeze system, antifreeze fluids, additives and inhibitors

When necessary, antifreeze fluids, additives and inhibitors can be used only if the manufacturer of such fluids or additives guarantees that they are suitable and do not cause damage to the exchanger or other components and/or materials of the boiler and system. Do not use generic antifreeze fluids, additives or inhibitors that are not specific for use in heating systems and compatible with the materials of the boiler and system.

3.4 Gas connection

The gas must be connected to the relevant connection (see fig. 2.3) in conformity with the current standards, using a rigid metal pipe or a continuous surface flexible s/steel tube and installing a gas cock between the system and boiler. Make sure all the gas connections are tight.

3.5 Electrical connections

IMPORTANT

BEFORE CARRYING OUT ANY OPERATION THAT REQUIRES REMOVING THE CASING, DISCONNECT THE BOILER FROM THE ELECTRIC MAINS WITH THE MAIN SWITCH.

NEVER TOUCH THE ELECTRICAL COMPONENTS OR CONTACTS WITH THE MAIN SWITCH TURNOED ON! DANGER OF ELECTRIC SHOCK WITH RISK OF INJURY OR DEATH!

The unit must be connected to an efficient grounding system in accordance with applicable safety regulations. Have the efficiency and suitability of the grounding system checked by professionally qualified personnel; the Manufacturer declines any liability for damage caused by failure to earth the system.

The boiler is prewired and provided with a three-pole cable, without a plug, for connection to the electric 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. Make sure to respect the polarities (LINE: brown wire / NEUTRAL: blue wire / GROUND: yellow-green wire) in the connections to the electric line.

The unit's supply cable MUST NOT BE REPLACED BY THE USER. If the cable gets damaged, turn the unit off and have the cable replaced only by professionally qualified personnel. In case of replacement, only use cable "HAR H05 VV-F" 3 × 0.75 ~mm^2 with max. external diameter of 8 ~mm .

Room thermostat (optional)

IMPORTANT: THE ROOM THERMOSTAT MUST HAVE VOLTAGE-FREE CONTACTS. CONNECTING 230 V TO THE ROOM THERMOSTAT TERMINALS WILL PERMANENTLY DAMAGE THE ELECTRONIC BOARD.

When connecting time controls or a timer, do not take the power supply for these devices from their breaking contacts. Their power supply must be by means of direct connection from the mains or with batteries, depending on the kind of device.

Accessing the electrical terminal block

The electrical terminal block can be accessed after removing the casing. The layout of the terminals for the various connections is also given in the wiring diagram in fig. 23.

fig. 10 - Accessing the terminal block

3.6 Air/fume ducts

The diameter of the flue connection pipe must not be less than that of the connection on the anti-backflow device. Starting from the anti-backflow device it must have a vertical section at least 50~cm long. Current standards must be complied with regarding sizing and installation of the flues and connection pipe.

The boiler is also equipped with a safety device (fume thermostat) that stops operation of unit in case of inadequate draught of obstruction of the flue. This device must never be tampered with or deactivated.

4. SERVICE AND MAINTENANCE

Important

All adjustment, conversion, commissioning and maintenance operations described below must only be carried out by Qualified Personnel (meeting the professional technical requirements of current regulations) such as the personnel of the Local After-Sales Technical Service.

FERROLI declines any liability for damage and/or injury caused by unqualified and unauthorized persons tampering with the unit.

Activation of Auto-setting function for gas valve calibration

THIS PROCEDURE MUST ONLY BE CARRIED OUT IN THE FOLLOWING CASES: GAS VALVE REPLACEMENT, CARD REPLACEMENT, CONVERSION FOR GAS CHANGE.

The B&P Gas Valve (with integrated modulating operator) does not provide for mechanical calibration: the minimum and maximum power adjustments are therefore electronically done via two parameters:

Contents	Description	Natural Gas	Propane Gas
q01	Absolute minimum current offset 0÷100	0÷150
q02	Absolute maximum current offset	0÷100	0-150

Gas valve pre-calibration

1. Connect a pressure gauge to monitor the gas valve outlet pressure.
2. Enable the Auto-setting function (Parameter b12=1).
3. Activate the calibration procedure by pressing the heating + button and Eco/Comfort button together for 5 seconds. The message "Au-to" immediately appears (in two successive flashes) and the burner is lit. Within 8 seconds (natural gas and LPG) the boiler finds the ignition point. The ignition point, absolute minimum current Offset (Parameter q01) and absolute maximum current Offset (Parameter q02) values are stored by the card.

Gas valve calibration

1. The display will show "q02" flashing; the modulation current is forced to the pre-calibration value of the absolute maximum current Offset parameter (Parameter q02)
2. Press the DHW buttons to adjust the parameter "q02" until the maximum nominal pressure minus 1mbar is reached on the pressure gauge. Wait 10 seconds for the pressure to stabilise.
3. Press the DHW "+?" button to set the parameter "q02" until the maximum nominal pressure is reached on the pressure gauge. Wait 10 seconds for the pressure to stabilise.
4. If the pressure read on the pressure gauge is different from the maximum nominal pressure, proceed in increments of 1 or 2 units of the parameter "q02" by pressing the DHW "+" button: after each change, wait 10 seconds for the pressure to stabilise.
5. When the pressure read on the pressure gauge is equal to the maximum nominal pressure (the newly calibrated value of the parameter "q02" is automatically saved), press the heating - button: the display will show "q01" flashing; the modulation current is forced to the pre-calibration value of the absolute minimum current Offset parameter (Parameter q01).
6. Press the DHW buttons to adjust the parameter "q01" until the minimum nominal pressure plus 0.5mbar is reached on the pressure gauge. Wait 10 seconds for the pressure to stabilise.
7. Press the DHW "..." button to adjust the parameter "q01" until the minimum nominal pressure is reached on the pressure gauge. Wait 10 seconds for the pressure to stabilise.
8. If the pressure read on the pressure gauge is different from the minimum nominal pressure, proceed in decrements of 1 or 2 units of the parameter "q01" by pressing the DHW "..." button: after each change, wait 10 seconds for the pressure to stabilise
9. When the pressure read on the pressure gauge is equal to the minimum nominal pressure (the newly calibrated value of the parameter "q01" is automatically saved.), recheck both adjustments by pressing the healing buttons and correct them if necessary by repeating the procedure described above.
10. The calibration procedure ends automatically after 15 minutes or by pressing the heating "+" and Eco/Comfort buttons together for 5 seconds.

• 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 stages.
• Check correct boiler lighting by performing various tests, turning it on and off with the room thermostat or remote control.
• Make sure the fuel consumption indicated on the meter matches that given in the technical data table in cap. 5.
• Make sure that with no demand for heating, the burner lights correctly on opening a hot water tap. Check that in heating mode, on opening a hot water tap, the heating circulating pump stops and there is regular production of hot water.
• Make sure the parameters are programmed correctly and carry out any required customisation (compensation curve, power, temperatures, etc.).

4.3 Maintenance

IMPORTANT

ALL MAINTENANCE WORK AND REPLACEMENTS MUST BE CARRIED OUT BY SKILLED QUALIFIED PERSONNEL.

Before carrying out any operation inside the boiler, disconnect the power and close the gas cock upstream. Otherwise there may be a danger of explosion, electric shock, suffocation or poisoning.

Periodical inspection

To ensure proper operation of the unit over time, have qualified personnel carry out a yearly inspection, providing for the following checks:

• The control and safety devices (gas valve, flow switch, thermostats, etc.) must function correctly.
• The fume exhaust circuit must be perfectly efficient. (Sealed chamber boiler: fan, pressure switch, etc. - The sealed chamber must be tight: seals, cable glands, etc.) (Open chamber boiler: anti-backflow device, fume thermostat, etc.)
  The air/fume terminal and ducts must be free of obstructions and leaks
• The burner and exchanger must be clean and free of deposits. Do not use chemical products or wire brushes to clean.
  The electrode must be properly positioned and free of deposits.

fig. 14 - Electrode positioning

The gas and water systems must be tight.
The pressure of the water in the system when cold must be approx. 1 bar; otherwise, bring it to that value.
The circulating pump must not be blocked.
The expansion tank must be filled.
- The gas flow and pressure must match that given in the respective tables.

4.4 Troubleshooting

Diagnostics

The boiler has an advanced self-diagnosis system. In case of a boiler fault, the display will flash together with the fault symbol (detail 11 - fig. 1) indicating the fault code.

There are faults that cause permanent shutdowns (marked with the letter "A"): to restore operation, press the RESET button (detail 6 - fig. 1) for 1 second or RESET on the optional remote timer control if installed. At this point the display will show "d4" for about 30 seconds or "d5" for about 5 minutes which indicates the waiting time after which the boiler will resume normal operation. If the boiler fails to restart, it is necessary to eliminate the fault.

Other faults cause temporary shutdowns (marked with the letter "F") which are automatically reset as soon as the value returns within the boiler's normal working range.
