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.
WARNING
This boiler is intended for production of hot technical water only:
• For heating of residential, commercial and industrial rooms.
• For heating of industrial process water.
• For indirect production of domestic hot water.
Any other use is forbidden.
DANGER
This boiler must be installed by qualied personnel.
The installation by unqualied personnel is forbidden.
DANGER
This boiler must be installed in compliance with the requirements of the technical standards and legislation in force rela-
ting to gas appliances, particularly with reference to ventilation of the premises.
Any installation that does not comply with the requirements of the technical standards and legislation in force is forbid-
den.
DANGER
This boiler must be installed according to the manufacturer’s instructions given in this manual. Incorrect installation may
cause injury to persons and/or animals and damage to property. The manufacturer shall not be held liable for any such
injury and/or damage.
WARNING
This boiler must be installed inside the building or in a partially sheltered place.
A partially sheltered place is a place which is not directly exposed to atmospheric agents.
Any installation in a place that is not partially sheltered is forbidden.
DANGER
This boiler must be correctly and safely connected to an electrical system compliant with the existing technical stan-
dards.
Any incorrect and unsafe connection to the electrical system is forbidden.
It is forbidden to connect the boiler to an electrical system lacking a differential switch to protect the boiler power line.
Any connection to an electrical system lacking a proper grounding system is forbidden.
WARNING
The boiler is supplied with a three-poled power cable, already connected to the electronic board and it is provided with
a safety clamp.
This boiler must be connected to a 230V power supply network, as indicated on the label afxed to the power cable.

DANGER
Carefully read the instructions relating to air intake and ue gas venting systems in the specic section of this manual.
DANGER
This boiler must be connected to a gas distribution system which complies with the existing technical standards.
Check the gas system state of conservation before installing the boiler.
Any connection to a gas system which does not comply with the existing technical standards is forbidden.
When connecting the boiler to gas supply network, it is compulsory to install an appropriately sized gasket made from
suitable material.
The boiler gas inlet coupling is not suitable for hemp, teon tape or similarly made gaskets.
After connecting the boiler, check the connection for tightness.
Once gas is in the pipes, leak test by a naked ame is forbidden; use specic products available on the market.
DANGER
With gas red 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 ames and do not smoke.
• Close the main gas cock.
• Open doors and windows.
• Contact a Service Centre, a qualied installer or the gas supply company.
Never use a ame 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.
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.
Damage and/or injury caused by incorrect installation or use and/or damage and/or injury due to non-observance of the manufactu-
rer’s instructions shall release the manufacturer from any and all contractual and extra-contractual liability.
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 specic waste ma-
nagement 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 qualied 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.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack
of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person
responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.

DANGER
Before starting the boiler, and each time it is at a standstill for several days, make sure the trap is full of water.
If the trap is empty, ll it by pouring water into the boiler through the ue gas venting duct.
WARNING
The boiler must be serviced periodically as indicated in the relevant section of this manual.
Appropriate boiler maintenance ensures efcient 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 system serviced and repaired by qualied personnel, satisfying all prevailing law require-
ments, and trained to properly carry out these operations.
In the event of long periods of inactivity of the boiler, disconnect it from the electrical power mains and close the gas cock.
WARNING
With the electrical power disconnected and the gas tap closed, the device’s electrical anti-freeze function does not work.
Should there be a risk of freezing, add antifreeze: it is not advisable to drain the system as this may result in damage; use specic
anti-freeze products suitable for multi-metal heating systems.
DANGER
Damage and/or injury caused by incorrect installation and/or incorrect use and/or unauthorized changes to the boiler
and/or non-observance of the manufacturer’s instructions and/or of the relative standards/laws in force in the country of
installation, shall release the manufacturer from any and all liability.

1.2 Boiler ignition
DANGER
It is presumed that the boiler has been installed by a qualied installer, it has been commissioned and is ready to operate
correctly.
For boiler ignition, proceed as follows:
• Open the gas cock installed ahead of the boiler.
• Turn the master switch installed ahead of the boiler ON. The boiler
display turns on and sets to “OFF” status.
• Press key to switch the boiler on. The display turns on and the
boiler sets to the last selected status.
• Select the desired operating mode (see Selecting the operating
mode on page 13).

1.5 TIMER setting
It is possible to set the time slots during which the boiler must operate (in standard or ECO mode), if heat is requested, and those
during which the boiler must remain OFF.
There is a maximum of 6 programmable time slots in the 24 hour time frame.

This function is useful in case of temporary absences (weekends, travels, etc.).

During the period of absence the boiler must be electrically supplied, must remain in “WINTER” mode and the gas cock
must remain open.
If this is not the case the boiler cannot work.
