MAX. LENGTH REGULATOR L1+L2 (m) 0 ÷ 20 NUVOLA3 COMFORT 280 Fi 20 ÷ 30 N.B.: For the C52 type, do not fit the flue and air duct terminals on opposite walls of the building. The air duct (for hori- zontal flues) must have a maximum length of 10 metres (6 m for model 140 Fi).
17. ELECTRICAL CONNECTIONS This machine is only electrically safe if it is correctly connected to an efficient earth system in compliance with current safety regulations. Connect the boiler to a 230V single-phase earthed power supply using the supplied three-pin cable, observing correct LIVE-NEUTRAL polarity.
18. INSTALLING THE CLIMATE CONTROLLER To connect the climate controller, proceed as described below: • Open the climate controller (there are no screws) levering with your hands; • Connect the two wires from the boiler terminal block M2 (figure 11) as illustrated in figure C. WARNING the climate controller has LOW VOLTAGE.
