Brahma Burner control (flame safeguard) SM592N.2 36223161

The SM592N.2 is a burner control (flame safeguard) for gas or oil burners. It manages the ignition sequence and enforces safety times, reading signals from the air pressure switch, gas pressure switch, and flame detector while driving the ignition transformer, fuel valve, and fan. On a heat demand it starts pre-purge, ignition spark, fuel admission, and flame proving within the set safety time. If no flame is detected, it locks out. This control can be used with ionisation, UV, or IR flame detection methods.

Parts of this type are selected by exact series and type designation, supply voltage, safety times (pre-purge and flame-proving), flame detection method (ionisation, UV, or IR), and physical base or plug pattern. A control box from a different series or with mismatched safety times is not interchangeable, even within the same brand. For a replacement, verify that the new unit matches the burner's existing wiring, voltage, and programmed sequence; a substitution with incorrect parameters creates a safety hazard rather than a functional alternative.
