Brahma Control box SM11FR 37172414

The Brahma SM11FR control box (SKU 37172414) is a microprocessor-based flame safeguard for automatic ignition control, flame monitoring, and safe operation of atmospheric gas burners with forced air supply. It supports ionization flame detection and is compatible with gas burners from Riello, Baltur, Lamborghini, Weishaupt, Master, and Oklina. The device operates in intermittent mode, performing pre-purge, ignition, and monitoring sequences, with a flame loss reaction time of less than one second. It includes a built-in ignition transformer and manual reset for emergency lockout, complying with EN 298 standards.

When selecting a replacement control box of this type, ensure the exact series and type designation match the original, as different series are not interchangeable. Critical parameters include supply voltage, safety time, pre-purge time, and flame detection method (ionisation, UV, or IR). The base or plug pattern must also match the mounting. Always verify the existing control's markings before ordering.

Common failure modes include lockout due to no flame detected, ionization circuit break, or ignition failure, causing the burner to shut down and require manual reset. Symptoms may include repeated lockouts, failure to start, or burner shutdown during operation. Check the flame sensor, wiring, and control box for faults.
