Conform to: Gas Directive 90/396/CEE E.M.C. Directive 89/336/CEE L.V. Directive 73/23/CEE Reference standard: EN676 WHILE STOCK LASTS TECHNICAL AND FUNCTIONAL CHARACTERISTICS • Two-stage operation (high/low flame). • Air-gas mixing at blast-pipe. • Ability to obtain optimal combustion values by regulating combustion air and blast-pipe. • Maintenance facilitated by the fact that the mixing 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. • Possibility to chose gas train with valve tightness control. • Equipped with one 4 and 7-pole connector, one flange and one insulating seal for boiler fastening. • On request: longer blast tube. CONSTRUCTION CHARACTERISTICS The burner consists of: (except the W version). • 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. • Air pressure switch to ensure the presence To be ordered separately: of combustion air. • Gas train complete with operation and • Automatic control and command safety valve, minimum pressure switch, equipment for the burner, compliant with pressure regulator and gas filter.
