THE WARNINGS CONTAINED IN THIS SECTION ARE ADDRESSED BOTH TO THE USER AND TO INSTALLATION AND
MAINTENANCE PERSONNEL.
THE USER WILL FIND INFORMATION ON OPERATION AND LIMITS OF USE IN THE ACCOMPANYING MANUAL, WHICH SHOULD BE
READ VERY CAREFULLY.
STORE THE MANUAL CAREFULLY FOR FUTURE REFERENCE.

1) GENERAL WARNINGS
INSTALLATION MUST BE PERFORMED IN OBSERVANCE OF CURRENT NORMS, ACCORDING TO THE CONSTRUCTOR’S

INSTRUCTIONS, AND BY PROFESSIONALLY QUALIFIED PERSONNEL.
THE INSTALLATION INSTRUCTIONS MANUAL MUST BE ALWAYS ACCOMPANY THE BOILER.
PROFESSIONALLY QUALIFIED PERSONNEL ARE THOSE HAVING TECHNICAL COMPETENCE IN THE SECTOR OF APPLICATION

OF THE DEVICE (CIVIL OR INDUSTRIAL), AND, IN PARTICULAR, THE CONSTRUCTOR’S AUTHORISED SERVICE CENTRES.
INCORRECT INSTALLATION MAY CAUSE DAMAGE TO PERSONS, ANIMALS, OR PROPERTY, FOR WHICH THE CONSTRUCTOR

ASSUMES NO LIABILITY.

• After completely removing the packing, make sure that the contents are in perfect condition.

• In case of doubt, do not use the equipment. Consult the supplier.

• Packing materials (cardboard carton, wooden crate, nails, clips, plastic bags, polystyrene, etc.) are potentially dangerous and must be

kept away from children.

• Before performing any cleaning or maintenance operation, turn off the unit by means of the mains switch and/or by means of the

appropriate cut-off devices.

• Do not block the air intake or heat dissipation grates.

• In the event of breakdown and/or poor functioning of the device, turn it off and do not attempt to repair it or take any direct action. Refer

to professionally qualified personnel only.

• Any repairs must be performed exclusively by a service centre authorised by the constructor, and with original spare parts only.

• Non-observance of the above instruction may compromise the safety of the device. To guarantee efficient and correct operation, the

device should undergo period maintenance by professionally qualified personnel according to the constructor’s instructions.

• Whenever the device is to be put out of service, secure all potentially hazardous parts to prevent accidents or damage.

• If the device is sold or transferred to another owner, or if you move and leave the boiler, make sure that this booklet stays with the boiler

so that it may be consulted by the new owner and/or by the installer.

• Use only original spare parts for all devices with optionals or kits (including electrical ones).

WARNING: this device must be used for its intended purpose, i.e., heating and production of domestic hot water. Any other use is improper
and therefore dangerous. The constructor will have no contractual or extracontractual liability for damage caused by incorrect installation
and/or use or by non-observance of instructions supplied by the constructor.

This device must be used exclusively with a sealed central heating system equipped with an expansion vessel.

2) WARNINGS REGARDING INSTALLATION

Warranty expires 12 months from date of installation and in all cases no later than 18 months from date of construction. First start-up
must be performed by authorised personnel only. For any operation on the hydraulic, gas, or electrical circuit regarding the heating unit,
refer to authorised technicians only and use original spare parts only. Wall-mounted boilers are not to be installed in damp rooms, and
must be protected against sprays or jets of water or other liquids to prevent malfunctions of the electrical and heating devices. They must not
be exposed to direct steam from cookers, and nothing must be placed on top of them. This heating unit has been constructed to heat the
home and to produce hot water. The constructor declines all responsibility for incorrect installation and/or use of the device. Do not
leave the device on when it is not being used: close the gas cock and turn off the mains switch. If you smell gas in the room in which the
device is installed, do not operate any electrical switches, telephones, or any other device that might cause a spark. Immediately open doors
and windows to create an air current to clear the room. Close the main gas cock (at the meter) or the cylinder cock, and request immediate
technical service.

Do not tamper with the device.

Installation Manual

SYSTEMS WITH THERMOSTATS

A by-pass must be installed in heating systems with radiators thermostats.
As required by current norms, these devices must be installed by qualified personnel only, who must respect norms UNI-CIG 7129 and
7131 and revisions, fire department regulations, and requirements of the local gas company. Before installing the boiler, make sure that the
water and heating systems are compatible with its output. The room must be properly ventilated by means of an air intake (see UNI 7129/92
and UNI 7129/95 FA).
The air intake must be at floor level open flue only, at a point where it cannot be obstructed, and protected by a grate that does not reduce
the useful section of flow.
The use of air flows from adjacent rooms is permitted as long as such rooms are in depression with respect to the outside and as long as
there are no wood-burning fireplaces or fans installed there. If the boiler is to be installed externally (for example, on balconies or
terraces), make sure that it is protected against atmospheric agents to prevent damage to components and voiding of the warranty. In such
cases we recommend building a heat compartment to protect the boiler against inclement weather.
Check the technical data on the packing and on the plate located inside the front casing. Check that the burner is suitable for use with
the type of gas available.
Make sure that all pipes and connections are perfectly sealed and that there are no gas leaks.
All pipework should be chemically flushed to remove any residues that might negative effect the operation of the boiler.

3) GENERAL WARNINGS BASED ON TYPE OF POWER SUPPLY

POWER SUPPLY
Electrical safety is achieved only when the device is correctly and efficiently earthed as per current safety norms (IEC 64-8 Electrical Part).

• This fundamental safety requirement must be checked. In case of doubt, request a check of the electrical system by professionally

qualified personnel. The constructor will not be liable for any damage caused by lack of or improper earthing of the system.

• Have professionally qualified personnel check that the electrical system is adequate for the maximum absorbed power of the device

(indicated on the plate). In particular, make sure that the section of the system wires is suitable for the maximum absorbed power of the
device.

• Do not use adapters, multiple sockets, and/or extension cords to power the device from the electrical mains.

• Provide a unipolar switch as required by current safety regulations to connect the device to the mains.

• The use of any electrical device requires the observance of some fundamental rules, such as:

• do not touch the device with wet or damp parts of the body and/or with bare feet

• do not pull on electrical cables

• do not expose the device to atmospheric agents (rain, sun, etc.) unless specifically provided for

• do not allow the device to be used by children or anyone unfamiliar with its operation

• The power cable must not be replaced by the user.

• If the cable becomes damaged, turn off the device and have the cable replaced by professionally qualified personnel only.

• If you decide not to use the device for an extended length of time, turn off the mains switch that feeds all components of the

system using electrical energy (pumps, burner, etc.).
