LGB... Burner Controls

Burner controls for the supervision of 1- or 2-stage gas or gas/oil burners of small to medium capacity (typically up to 350 kW), with or without fan, in intermittent operation.


The LGB... burner controls are used for the startup and supervision of 1- or 2-stage gas or gas/oil burners in intermittent operation.

Depending on the type of burner control used, the flame is supervised either by an ionization probe, a blue-flame detector QRC1... for forced draft gas/oil burners, or a UV detector QRA... (with auxiliary unit AGQ1...A27).

In connection with the respective adapters, the LGB... burner controls replace their predecessor types LFI7... and LFM1... (also refer to «Replacement types» under «Ordering»).
