TECHNICAL AND FUNCTIONAL CHARACTERISTICS • Low NOx and CO emissions gas burner compliant with European standard EN676 “Class III”. • Single stage operation (on/off). • High ventilation efficiency, low electrical input, low noise. • Air-gas mixing at blast-pipe. • Exhaust gas recycling blast-pipe able to achieve very low pollutant emissions, particularly with regard to nitrous oxides (NOx). • Maintenance facilitated by the fact that the mixing unit can be removed without having to remove the burner from the boiler. • Manual air flow adjustment. • Gas regulation by means of a two-stage working valve that is electromagnetically driven. • Possibility to chose gas train with valve tightness control. • Equipped with one 7-pole connector, one flange and one insulating seal for boiler fastening. • Gas train exit is possible either from the top or from the bottom. CONSTRUCTION CHARACTERISTICS Conform to: Gas Directive 90/396/CEE E.M.C. Directive 89/336/CEE L.V. Directive 73/23/CEE Reference standard: EN676 The burner consists of: • Combustion air intake with air flow adjustment device. • Sliding boiler coupling flange to adapt the head protrusion to the various types of boilers. • Flame viewer. • Air pressure switch to ensure the presence of combustion air. • Manual air flow adjustment. • Flame detection by ionisation electrode. • Synoptic control panel with led of operation and block and burner off, operation and block indicator. • Automatic control and command equipment for the burner, compliant with Electrical supply European standard EN298. • Printed circuit electrical connections. • Intelligent connectors for burner/train (error proof). • 7 poles plug for the auxiliary feeding and for the thermostatic connection. • Prepared for microamperometer connection with ionisation cable. • Electrical protection rating IP44. To be ordered separately: • Gas train including safety and 1°/2° stage working valve that is electromagnetically driven, minimum pressure gauge, pressure adjuster and gas filter. Boiler coupling kit - 7 pin plug 12) Valve tightness control not required by EN676. CTV) Gas train with Valve Tightness Control. **) Maximum gas inlet pressure at pressure regulator in CE version, at gas train for EXP version. Net calorific value of natural gas: Hi = 35,80 MJ/m3 = 8550 kcal/m3, at reference conditions of 0°C, 1013 mbar.
