ABSTRACT:
An electronic network for safe operation of an infrared flame flicker burner control system is disclosed. The network is placed across the infrared flame detector and modifies the detector's action in the event of a flameout so that a refractory shimmer effect is reduced to avoid falsely causing the burner control system to indicate the presence of flame.
