Brahma Control box VM41 37200031

The Brahma VM41 control box (SKU 37200031) is a microprocessor-based burner manager for gas forced draft burners. It is designed for single-stage burners with direct ignition and uses ionization flame detection. The unit operates in intermittent (cyclic) mode and is suitable for thermal power up to 120 kW per EN 676 and up to 350 kW per DIN 4788. It includes manual reset safety lockout, two independent safety contacts, and built-in varistor and fuse.

When selecting a control box of this type, verify the series and type designation, supply voltage, safety times (pre-purge duration, flame establishment period, lockout behavior), flame detection method, and mechanical base or plug pattern. Controls are generally not interchangeable across series, even within the same brand. Confirm the original unit's series marking, voltage rating, and timing settings against catalogue data before ordering.

Typical failures include lockout due to flame loss or ignition failure, which requires manual reset after eliminating the cause. The equipment may fail to start or shut down unexpectedly. Check the ionization electrode, wiring, and safety contacts for faults.
