Siemens LFL1.148 Control Box
240v
Burner control for atmospheric gas burners with intermittent operation. For safety reasons - self-test of the flame supervision circuit, etc. - at least one controlled shutdown is required every 24 hours

The LFL1.148 is used for the supervision of single- or two-stage atmospheric gas burners of medium to high capacity.

The gas burner control has a connection facility for an auxiliary fan or flue gas fan.
Example: condensing boilers.

Flame supervision is ensured by means of ionization current detector electrodes; one electrode is used for the first stage and one for the second stage. Changeover takes place automatically after release of the second fuel valve.
