General notes for installing and maintenance technicians, and users
This instruction manual is an integral and essential part of the product. It shall be supplied by the installer to the user who shall keep it carefully
to consult it whenever necessary.
This document shall be supplied together with the equipment in case the latter is sold or transferred to others.
DANGER
This equipment has been manufactured to be connected to a room heating system and to a DHW distribution system.
Any other use shall be considered unsuitable and dangerous for people, animals, and/or property.
The equipment shall be installed in compliance with the prevailing standards and in accordance with the manufacturer's instructions specified
in this manual: the manufacturer will not be held responsible for injuries to people and animals and/or damages to property resulting from
an incorrect installation.
Damage and/or injury caused by incorrect installation or use and/or damage and/or injury due to non-observance of the manufacturer’s
instructions shall release the manufacturer from any and all contractual and extra-contractual liability.
Before installing the boiler, check that the technical data correspond to the requirements for its correct use in the system.
Check that the boiler is intact and it has not been damaged during transport and handling. Do not install equipment which is clearly damaged
and/or faulty.
Do not obstruct the air intake openings.
Only original accessories or optional kits (including the electric ones) are to be installed.
Properly dispose of the packaging as all the materials can be recycled. The packaging must therefore be sent to specific waste management
sites.
After removing the packaging, make sure that its elements (clips, plastic bags, foam polystyrene etc.) are note left within the reach of children
as they are potential hazard sources.
In the event of failure and/or faulty functioning, switch off the boiler. Do not attempt to make repairs: contact qualified technicians.
Original parts must be used for all repairs to the boiler.
Non-observance of the above requirements may affect the safety of the boilers and endanger people, animals and/or property.
WARNING
The boiler must be serviced periodically as indicated in the relevant section of this manual.
Appropriate boiler maintenance ensures efficient operation, environment preservation, and safety for people, animals and objects.
Incorrect and irregular maintenance can be a source of danger for people, animals and property.
The user is strongly advised to have the boiler serviced and repaired by a qualified Service Centre.
In the event of long periods of inactivity of the boiler, disconnect it from the electrical power mains and close the gas cock. The electronic
antifreeze function will not be operative with the device disconnected from the electric power supply and gas cock closed.
Should there be a risk of freezing, add antifreeze: it is not advisable to drain the system as this may result in damage;use specific anti-freeze
products suitable for multi-metal heating systems.

DANGER
With gas fired boilers, take the following measures if you smell gas:
•Do not turn on or off electric switches and do not turn on electric appliances.
•Do not ignite flames and do not smoke.
•Close the main gas cock.
•Open doors and windows.
•Contact a Service Centre, a qualified installer or the gas supply company.
Never use a flame to locate a gas leak.
The boiler is designed for installation in the countries indicated on the technical data plate: installation in any other country may
be a source of danger for people, animals and/or property.
The manufacturer will bear no contractual and tortious liability for failure to comply with all the instructions above.

Rapid operating instructions
The following instructions will help you to switch the boiler on quickly and regulate it for immediate use.
WARNING
It is presumed that the boiler has been installed by a qualified installer, it has been commissioned and is ready to operate correctly.
If any accessories have been fitted on the boiler, these instructions will not cover them. You will therefore have to refer to the full
boiler instructions as well as to the specific instructions for the accessories.
This manual contains full details of how the boiler works, and full operating and safety instructions.
1. Open the gas cock installed ahead of the boiler.
2. Turn the master switch installed ahead of the boiler ON; the boiler display turns on.
3. If you do not wish to activate the CH function, press the button until displaying the symbol : only the
DHW function will be enabled.
4. If you wish to activate both the heating and DHW functions, press the button until displaying the symbol
.
5. If you do not wish to activate the DHW function, press the button until displaying the symbol : only
the CH function will be enabled.
6. To enable water heater heating press button, the display shows the writing “COMFORT” (if it was enabled,
this operation disables it). Warning: if water heater heating is disabled, the boiler can still heat domestic water
through the solar plant, of course only if the atmospheric conditions allow it (see par. Water heater freeze
protection function on page 24).
7. To set the domestic hot water temperature, press DHW +/- buttons.
8. To set the heating water temperature, press CH +/- buttons.
9. Set the desired temperature on the (optional) ambient thermostat in the building. The boiler is now ready to
operate.
If the boiler shuts down, press button.
If boiler does not resume its operation after three attempts, contact a qualified Service Centre.

After this time, value is stored and display standard operation will be restored.
1.5 Comfort function enable/disable
This function keeps the water heater hot (top part) ignoring the existing water heater heating programming, if any (see par. Heating and water
heater programme mode on page 20). When the "COMFORT" icon is on, the function is enabled. When it is off the function is disabled and the
boiler follows the set water heater hour programming. If the "comfort" function is disabled and no programming is set, the boiler can still heat
the domestic water naturally through the solar plant, if the atmospheric conditions allow it.
If "COMFORT" function is enabled (“COMFORT” icon ON), press "OK" button to disable it.
If "COMFORT" function is disabled (“COMFORT” icon OFF), press "OK" button to enable it.
Water heater heating, through the comfort function or programming, is carried out only if the boiler is in SUMMER or WINTER mode.
If the boiler is in CH ONLY or OFF operating mode the water heater is not heated.

When no ambient probe is connected, the two day/night levels will acquire the on and off values.
Heating is ON in the selected periods with the icon, while it is OFF in the selected periods with the icon.
In case of connection with "Open Therm" Remote Control, that zone shall not be managed by boiler boards, as it will be directly managed by
the remote control and, as a consequence, zone programming will be inhibited.
