Brahma Control box SM152N.2 24283963

The Brahma SM152N.2 control box (SKU 24283963) is a microprocessor-based burner management system for automatic ignition control, flame monitoring, and safe operation of atmospheric gas burners with an intermittent cycle. It supports ionisation, UV, and IR flame detection methods. The device includes a built-in ignition transformer and performs a fully automated combustion cycle: checking for false flame, pre-purge, ignition, flame monitoring, and safe shutdown upon flame loss. It features a manual reset lockout for safety and is a direct modern equivalent of the obsolete Brahma SM152.2.

Parts of this type are selected by exact series and type designation, supply voltage, required safety and pre-purge times, flame detection method (ionisation, UV, or IR), and base or plug pattern. Before ordering, verify the original equipment nameplate for the exact part number. Installation involves connecting the control to the gas valve, ignition transformer, fan, and air pressure switch, ensuring the flame detector matches the control's supported methods.

When items of this kind fail, the equipment may lock out without automatic restart, often due to no flame, ionization circuit break, or ignition failure. Symptoms include the burner failing to ignite, shutting down during operation, or requiring manual reset after a fault. Check the flame detector, ignition transformer, and wiring connections for faults.
