General
LME are used for the startup and supervision of 1- or 2-stage gas burners or gas burners in intermittent operation. Flame supervision takes place via an ionization probe or a QRA flame detector with AGQ3.xA27 ancillary unit for forced draft gas burners, or, in the case of blue-burning flames, with a QRC blue-flame detector. In terms of housing dimensions, the LME... are identical with the burner control LGB… and LMG… burner controls.
