8.3 ELECTRICAL ARRANGEMENT
All the units are fitted with an electrical supply cable: if this has to be replaced (e.g. if damaged), contact an authorized
Technical Service Centre.
Before connecting the unit, make sure that:
- the electrical system is fitted with a 6A thermo-magnetic circuit breaker
- the system characteristics meet the details on the data plate applied to the unit (electrical power, rated voltage, etc.)
- the system is fitted with an efficient ground connection, in compliance with the legal regulations in force (ground-
ing is compulsory by law)
- at no point should the supply cable reach an overtemperature of 50°C in comparison with the ambient temper-
ature. If direct connection to the network is required, an omnipolar switch must be used, with a 3mm minimum
opening between contacts, sized for the load stated on the plate and compliant with the regulations in force; the
yellow/green earth wire must not be interrupted by the switch. The omnipolar switch must be easily reachable
once the unit is installed.
If the unit is not used for a long time, disconnect the supply.
The Manufacturer accepts no responsibility if the above, as well as the usual safety regulations, are not complied with.
8.4 HYDRAULIC ARRANGEMENT
To work correctly, the stove must be appropriately connected to a heating system. Please remember the installation
must be done professionally by a qualified person or company in compliance with the provisions of Ministerial Decree
37/08. The Manufacturer accepts no responsibility for incorrect installations or if they are not carried out by a compe-
tent technician.
For the installation, refer to the UNI7129 and UNI10412 standards (and their respective amendments).
For a correct installation, check that there is no leak in the hydraulic system that may affect the operation of the stove
and its integrity. In this regard, the installation company must adopt the solutions it deems necessary to prevent the
heat exchange surfaces of the stove from being subjected to calcareous incrustations, sludge, ferrous system residues
and anything else unrelated to the heating water over time. This will allow optimizing the thermal efficiency and safe
operation of both stove and system. We recommend that you install a softener on the cold water inlet and a fine filter
on the stove piping, to filter the largest impurities.
- vent the heating system and the stove every time you fill it.
- connect and take outside the stove the discharge of the safety valve.
- on the return circuit, a chemical-physical water treatment system must be installed, for instance a
magnetic dirt separator: it is necessary to protect the stove internal components, such as the elec-
tronic circulator, from impurities and ferrous particles present in the system. Alternatively, use a
heat exchanger to separate the water of the stove from the system water.
- It is always mandatory to wash or restore the system in case of new installation and replacement
of the heat generator as required by the UNI8065 standard.
