Page 4: Operating Instructions
Please read this manual carefully since it provides important information on safe installation, use and maintenance. NINFA 32 MC is a high-efficiency heat generator for heating and domestic hot water production, running on natural gas or LPG, equipped with an atmospheric burner with electronic ignition and microprocessor control system, and designed for installation indoors or outdoors in a partially protected place (in compliance with EN 297/A6) for temperatures as low as -5°C (-15°C with optional antifreeze kit). - Page 5 NINFA 32 MC Indication during operation Heating A heating demand (generated by the Room Thermostat or Remote Timer Control) is indicated by lighting up of the ra- diator (detail 5 - fig. 1). The multifunction display (detail 9 - fig. 1) shows the heating sensor temperature.

NINFA 32 MC 1.3 Turning on and off Boiler not electrically powered fig. 5 - Boiler not electrically powered The antifreeze system does not work when the power and/or gas to the unit are turned off. To avoid damage caused by freezing during long idle periods in winter, it is advisable to drain all water from the boiler, DHW circuit and system;... -
Page 7: Adjustments
NINFA 32 MC When the boiler is turned off, the electronic board is still powered. Domestic hot water and heating operation are disabled. The antifreeze system stays on. To re-light the boiler, turn the selector (detail 3 fig. 1) to (winter) or (summer). - Page 8 NINFA 32 MC Domestic hot water (DHW) temperature adjustment Operate the DHW knob (detail 2 - fig. 1) to set the temperature between 40°C (min.) and 55°C (max.); fig. 11 Room temperature adjustment (with optional room thermostat) Using the room thermostat, set the temperature desired in the rooms. If the room thermostat is not installed the boiler will keep the heating system at its setpoint temperature.
- Page 9 NINFA 32 MC Compensation curve and curve shift Turn the selector (detail 3 - fig. 1) to RESET for 5 seconds and then to (winter) or (summer) and “CU” will be displayed. Operate the DHW knob (detail 2 - fig. 1) to adjust the required curve from 1 to 10 according to the characteristic (fig. 14).
- Page 10 NINFA 32 MC If the room temperature is lower than the required value, it is advisable to set a higher order curve and vice versa. Pro- ceed by increasing or decreasing in steps of one and check the result in the room.
- Page 11 NINFA 32 MC Water system pressure adjustment The filling pressure with system cold, read on the boiler water gauge, must be approx. 1.0 bar. If the system pressure falls to values below minimum, the boiler card will activate fault F37 (fig. 16).

NINFA 32 MC 2. Installation 2.1 General Instructions BOILER INSTALLATION MUST ONLY BE PERFORMED BY QUALIFIED PERSONNEL, IN ACCORDANCE WITH ALL THE INSTRUCTIONS GIVEN IN THIS TECHNICAL MANUAL, THE PROVISIONS OF CURRENT LAW, THE PRE- SCRIPTIONS OF NATIONAL AND LOCAL STANDARDS AND THE RULES OF PROPER WORKMANSHIP. -
Page 13: Gas Connection
NINFA 32 MC System water charcteristics In the presence of water harder than 25° Fr (1°F = 10ppm CaCO ), the use of suitably treated water is advisable in order to avoid possible scaling in the boiler. The treatment must not in any case reduce the hardness to values below 15°F (Decree 236/88 for uses of water intended for human consumption). -
Page 14: Electrical Connections
NINFA 32 MC 2.5 Electrical connections Connection to the electrical grid The unit's electrical safety is only guaranteed when correctly connected to an efficient earthing system exe- cuted according to current safety standards. Have the efficiency and suitability of the earthing system checked by professionally qualified personnel. -
