Brahma Control box 18048300

The Brahma Control box 18048300 is a microprocessor-based burner manager designed for forced-draft liquid fuel burners. It automates ignition, flame monitoring, and safe operation in intermittent mode, with a pre-purge time of 20 seconds. It supports flame detection via ionisation, UV, or IR detectors. This control box fits Brahma GF2 burners and is compatible with single-stage and two-stage burners without preheater, up to 30 kg/h capacity.

When selecting a replacement control box of this type, ensure the exact series and type designation match the original. Critical parameters include supply voltage, safety time, pre-purge time, and flame detection method. Verify the physical plug pattern or base layout and wiring diagram before installation. Burner controls are generally not interchangeable across different series, even within the same brand.

Typical failures include lockout due to flame loss or extraneous light, which triggers a manual reset. The control may also force a self-diagnostic stop every 24 hours of continuous operation. If the flame is not detected within the safety time, the control locks out and must be manually reset. Check the flame detector, air pressure switch, and wiring connections when troubleshooting.
