5. Manual reset safety thermostat (allows to reset the boiler after a primary circuit fluid overheat). 6. Control thermostat (allows to adjust the boiler temperature between 60°C (min. position) and 90°C (max. position)) SAFETY CUTOUT OF THE ACV BURNER If the burner has stopped. The burner indicator lights up. (fig. 2) 2.
• A minimum thermostat, fitted at the rear of the boiler and preset at 45°C, delays the heating pump activation. This prevents the risks of corrosion of the combustion chamber. Production of domestic hot water The “N” boilers can be combined with any ACV hot water production tank. CONSTRUCTION Outer body The outer body which holds the primary water is made from STW 22 heavy gauge steel.
TECHNICAL CHARACTERISTICS GENERAL MAXIMUM OPERATING CONDITIONS The appliances are delivered fully assembled, tested and packaged Maximum Service Pressure (DHW tank full of water) on a wooden support, protected by anti-shock corner pieces and - Primary circuit : ..............3 bar wrapped in a heatshrunk plastic film.

It is compulsory to have the boiler serviced once a year. Maintenance and the burner control must be performed by a qualified engineer. IMPORTANT If your "N" boiler is combined to an ACV hot water BOILER MAINTENANCE (fig. 15) production tank, it is essential to fill the DHW circuit before starting to fill the heating (primary) circuit.
