INTRODUCTION WHO SHOULD READ THESE INSTRUCTIONS APPLICABLE STANDARDS These instructions should be read by: - the specifying engineer - the installer - the user - the service engineer The products described in this document have been certified at European level (European Directive 92/42/EEC «Efficiency»). They have also been awarded the Belgian “OPTIMAZ” LABEL (fuel oil boiler).
USER GUIDE USE OF THE BOILER Before carrying out any work on the boiler, isolate it from the electrical supply at the switch on the external control box. Also place the main switch on the control panel to “OFF”. You should familiarise yourself with the control panel (fig. 1) The user must not attempt to gain access to the components inside the control panel. 1. Control thermostat When the boiler is used for heating only, the boiler temperature may be set at 60 to 90°C.
DESCRIPTION GENERAL DESCRIPTION Casing • Model N is a single boiler (heating). The boiler is covered with a steel casing that has been stove enamelled at 220°C after scouring and phosphating. • Equipment required: a water connection kit for the heating circuit supply (optional). BOILER VIEWS AND KEY TO PARTS • The N-Mini control panel includes a control thermostat and a thermostat pressure gauge.
TECHNICAL CHARACTERISTICS GENERAL OPERATING CONDITION LIMITS The appliances are supplied fully assembled, tested and packed standing on a timber base with impact protection strips and wrapped in heat-shrunk plastic film. When the appliance arrives, remove the packaging and check that no parts have been damaged in transit.
INSTALLATION BOILER ROOM Important • Never obstruct the ventilation. • Do not store inflammable products in the boiler room. • Avoid storing corrosive products such as paint, solvents, chlorine, salt, soap or other cleaning products near the boiler. A. B. C. D. E. F.
INSTALLATION CONNECTING THE HEATING SYSTEM HOT WATER CONNECTION ACV water kit ACV can supply an optional pre-assembled water kit. This kit comprises: Pressure reducing valve If the mains water pressure exceeds 6 bar, a pressure reducing valve calibrated to 4.5 bar must be installed. Safety group • A pump; • A 3-way manual valve.

COMMISSIONING MAINTENANCE FILLING THE HEATING CIRCUIT RECOMMENDATION It is compulsory to have the boiler serviced once a year. Boiler servicing and checking must be carried out by a qualified engineer. IMPORTANT If your “N” boiler is connected to an ACV tank, it is essential to fill the domestic water circuit before the heating circuit. 1. Open valves 5 and 8 to fill the heating circuit and make sure the pressure does not exceed 2 bars. 8 8 MAINTAINING THE BOILER 1.
