Electric supply to the boiler:
ADI CD 450 – 750: 230 V, 50 Hz, single-phase and ground.
ADI CD 850 – 950: 380 V, 50 Hz, three-phase and ground.

The electric protection of each boiler must be prepared considering the maximum value between the
electric consumption at the start-up and the electric consumption at the maximum power output.
ADI CD 450 to 750: modulating power from 30%.
(*) Minimum power output adjustable up to 30% of the gas power: to be adjusted onsite (during
commissioning), depending on installation factors
 second values of the above chart list.
