LFL1.335 110V – Siemens Burner Controller

Burner Flame Safeguard Control

The LFL… is a compact electro-mechanical primary safeguard control designed to provide burner sequencing, automatic ignition and continuous flame monitoring for gas, oil, and dual fuel, single burner applications.

The LFL… is applicable for on-off, multi-stage or modulating burners. The LFL… is designed for direct main burner ignition, intermittent or interrupted pilot operation.

The LFL… integrates the flame amplifier, purge timer and sequencer in a single control. Flame supervision is accomplished using UV sensor or flame rod detection.

The difference between 01 and 02 series is the duration of the safety time for the pilot burner of burners equipped with pilot gas valves.
