Brahma Control box TGRD91 18047162

The Brahma TGRD91 control box (SKU 18047162) is a microprocessor-based burner manager from the Kompact series, designed for single-stage liquid fuel air heaters and burners, as well as atmospheric gas burners in intermittent operation. It integrates a high-voltage ignition transformer and provides fixed time parameters: pre-purge time of 10 seconds and safety time of 5 seconds. Flame detection is via ionization. The device includes a non-volatile safety lockout with manual reset, cutting fuel supply and entering lockout state if flame is not established within the safety time.

When selecting a replacement control box of this type, ensure the series, supply voltage, safety time, pre-purge time, and flame detection method match the original specification. The physical connection pattern (base or plug type) and number of pins must be compatible with the existing wiring base. Verify that the control is certified for the burner's fuel type and that all connected sensors (flame detector, pressure switches, thermostats) are compatible with the control's input specifications. Always check the marking on the unit housing against your equipment requirements before ordering.

Typical failures of this kind of control box include failure to ignite, lockout without flame establishment, or intermittent operation. Symptoms may include the burner not starting, repeated lockouts requiring manual reset, or the control not responding to flame signal. Check the flame detector, wiring connections, and supply voltage, and verify that the control's time settings match the burner's requirements.
