Conform to: E.M.C. Directive 89/336/CEE L.V. Directive 73/23/CEE Reference standard: EN267 TECHNICAL AND FUNCTIONAL CHARACTERISTICS Two-stage light oil burners • Two-stage operation (high/low flame). • Ability to obtain optimal combustion values by regulating combustion air and blast-pipe. • 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 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: flexible hoses, line filter and pump. • Equipped with one 4 and 7-pole connector, one flange and one insulating seal for boiler fastening, 2 flexible hoses, one line filter and two nozzle. • On request: longer blast tube, operation on biodiesel. CONSTRUCTION CHARACTERISTICS SPARK 35 DSGW SPARK 35 DSG The burner consists of: • Flame detection by photoresistance. • Combustion air intake with air flow • 7-pole outlet for burner electrical and adjustment device. thermostat connections, and 4-pole outlet • Sliding boiler coupling flange to adapt the for second stage control. head protrusion to the various types of • Electrical protection rating IP40. boilers. • Sound-proof plastic protective cover • Device made from sound-absorbing (except the W version). material to reduce fan noise. • Gear pump with pressure regulator and fuel stop-cock valves. • Automatic control and command equipment for the burner compliant with European standard EN230.
