SYSTEM CLEANING
Before connecting the Boiler to the system, it is MANDATORY to wash the pipes thoroughly in order to remove any residues which
may compromise the correct operation of the Boiler.
HYDRAULIC CONNECTIONS
The hydraulic circuit must be built by an authorised company or by qualified personnel, in compliance with the Technical Standards
and the Law in force.
The components shall be charged to the installer that, at the end of the works, must issue a declaration of conformity.

IMPORTANT
–
Make sure that the hydraulic pressure measured downstream of the pressure regulator on the supply line does not
exceed the operating pressure indicated on the plate del Gruppo Termico.
–
Make sure that the drains of the safety valves del Gruppo Termico and of the heater, if any, are connected to a drain
funnel, so that the valves do not flood the room in case of intervention.
–
Make sure that the water and heating system pipes are not used as earthing point of the electrical system.
–
Once the heating system has been filled, it is recommended to close the supply tap and keep it closed so that any
system losses can be signalled by an hydraulic pressure drop detected on the system manometer.
–
For reasons of technical expertise, the system components must be chosen and installed by the installer, that must
operate in accordance with good practice regulations and Laws in force.
