SCHEMATIC DIAGRAM - SYSTEM FOR HEATING AND DOMESTIC HOT WATER

The choice and installation of the system components is up to the installer, who must operate according to good practice and the current
Legislation. Systems with antifreeze require the use of backflow preventers. Remember that the diagram in Fig. 26 is a schematic diagram.
In case of different systems, please contact our After-Sales Service which will provide all the elements you require.
