Installation of the boiler

The boiler is supplied disassembled with the 50FF/FC unit, for 

installation on site.
The hydraulic circuit is assembled inside the 50FF/FC unit. The 

installer must connect the connecting piping with the boiler.
Note: all this piping system is sent packed together with the boiler.
