Conform to: E.M.C. Directive 89/336/CEE L.V. Directive 73/23/CEE Reference standard: EN267 TECHNICAL AND FUNCTIONAL CHARACTERISTICS closure of gate to prevent any heat dispersion to flue. • When using biodiesel light oil (fuel of vegetable origin), the burner must be built with specific components: flex pipes, line filter and pump. • Equipped with one flange and one insulating seal for boiler fastening, 2 flexible hoses, one line filter and two nozzle. • On request: biodiesel operation. CONSTRUCTION CHARACTERISTICS • 7-pole outlet for burner electrical and thermostat connections, and 4-pole outlet for second stage control. • Electrical protection rating IP40. 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. • Automatic control and command equipment for the burner compliant with European standard EN230. • Flame check by means of infrared IRD photo-electric cell. Electrical supply Accessories available on request Part no. 97980053 Soundproof burner cover (see page 247) Two-stage light oil burners with low pollutant emissions • Low NOx and CO emissions light oil burner compliant with European standard EN267 “Classe III”. • Two-stage operation (high/low flame). • Suitable for working in combustion chambers different than reverse flame. • Ability to obtain optimal combustion values by regulating combustion air and 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 atomisation unit can be removed without having to remove the burner from the boiler. • Air flow regulation for first and second stage by means of electric servomotor with pause Light oil burner accessories Line filter - Flex hoses - Nozzles - Boiler coupling kit - 4 and 7 pin plug 2 Notes 4) Equipped with air closure device. 5) Biodiesel according to european norm EN14213-FAME. Net calorific value of light oil: Hi = 42,70 MJ/kg = 10200 kcal/kg.
