INSTALLATION
Essential recommendations for the correct operation of the system
•
As there is no built-in safety group (safety valve + pressure release valve) in the boiler,
make sure to install them in the system.
•
As there is no built-in CH pump in the boiler, the installer must provide one in the system.
•
The heating circuit must be designed so as to ensure a continuous flow in the boiler;
this flow may be obstructed if all the thermostatic valves are closed. In this case, install
a bypass.
