Gas Burner BTG 11 50-60HZ 48.8 - 99kW

TECHNICAL AND FUNCTIONAL CHARACTERISTICS

• Single stage operation (on/off).

• 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.

• Manual air flow adjustment.

• Possibility to chose gas train with valve tightness control (except BTG3).

• Equipped with one 7-pole connector, one flange and one insulating seal for boiler fastening.

• On request: longer blast tube.

CONSTRUCTION CHARACTERISTICS

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 connection with ionisation cable.

• Electrical protection rating IP40.

• Sound-proof plastic protective cover.

To be ordered separately:

• Gas train complete with operation and safety valve, minimum pressure switch, pressure regulator and gas filter.

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.
