TECHNICAL AND FUNCTIONAL CHARACTERISTICS • Single stage operation (on/off). tightness control (except BTG3). • Air-gas mixing at blast-pipe. • Equipped with one 7-pole connector, one • Ability to obtain optimal combustion flange and one insulating seal for boiler values by regulating combustion air and fastening. blast-pipe. • On request: longer blast tube. • 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. • Possibility to chose gas train with valve Conform to: Gas Directive 90/396/CEE E.M.C. Directive 89/336/CEE L.V. Directive 73/23/CEE Reference standard: EN676 To be ordered separately: • Gas train complete with operation and safety valve, minimum pressure switch, pressure regulator and gas filter. Electrical supply connection with ionisation cable. • Electrical protection rating IP40. • Sound-proof plastic protective cover. The burner consists of: • Combustion air inlet with device to adjust the air flow; automatically closing air gate. • Sliding boiler coupling flange to adapt the head protrusion to the various types of boilers (fixed on BTG 3). • Air pressure switch to ensure the presence of combustion air. • Automatic control and command equipment for the burner, compliant with European standard EN298. • Flame detection by ionisation electrode. • 7-pole outlet for burner electrical and thermostat connections. • Prepared for microamperometer Optionals Description Gas burner accessories Boiler coupling kit –7 pin plug 300 mm long combustion head 1) Equipped with air closure device. 12) Valve tightness control not required by EN676. CTV) Gas train with Valve Tightness Control. *) Minimum gas train inlet pressure needed to obtain maximum burner power with a combustion chamber backpressure of zero. **) Maximum gas inlet pressure at pressure regulator in CE version, at gas train for EXP version. Net calorific value at reference conditions of 0°C, 1013mbar: Natural gas HI 35,8MJ/m3 = 8550 kcal/m3 LPG HI 92MJ/m3 = 22000 kcal/m3
