Kromschroder Burner control unit IFD258-3/1W 84621610

The Kromschroder IFD258-3/1W burner control unit (SKU 84621610) is a fully electronic control box designed for direct ignition and flame monitoring of industrial gas burners. It operates on 120 V AC and supports both ionization and UV flame detection methods. The unit features a safety time of 3 seconds on start-up and can handle up to 250,000 operating cycles. It is suitable for forced draught burners and complies with EN 60730 safety standards, with an IP54 protection class and an ambient temperature range of -20 to 60 °C. The device weighs 682 g and can be installed in any position.

When selecting a replacement burner control unit of this type, ensure the supply voltage, flame detection method (ionization or UV), and safety time match the burner system's requirements. Verify the physical dimensions and cable gland size (e.g., M16) to fit the existing enclosure. The control unit must be compatible with the burner's ignition type and air supply configuration (e.g., forced draught). Always compare the article numbers and model specifications with the original part before ordering.

Common failure modes for burner control units include failure to ignite, intermittent flame loss, or lockout without restart. Symptoms may include the burner not starting, frequent shutdowns, or error codes on the control panel. Check the flame sensor (ionization or UV) for contamination or damage, and verify the supply voltage and wiring connections. If the unit fails to reset or shows no response, it may need replacement.
