Kromschroder Burner control unit IFD258-3/1Q 84621410

Kromschroder Burner control unit IFD258-3/1Q 84621410 is a control box for directly ignited industrial gas burners. It has a safety time of 3 seconds and supports ionization or UV flame detection. The unit operates on 120 V supply voltage and has a protection class of IP54. It is designed for forced draught burners and complies with EN 60730 safety standards. The device weighs 610 g and can be installed in any position.

Parts of this type are selected by matching the supply voltage, flame detection method, and safety time to the burner system. The control box must be hard-wired, and the cable gland size (M16) should be compatible with the existing wiring. Ensure the ambient temperature range and protection class meet the installation environment. The unit's installation position is flexible, but proper grounding is required.

When such control units fail, the burner may not ignite or may shut down unexpectedly. Common issues include failure to detect flame, leading to lockout or repeated restart attempts. Check the flame sensor and wiring connections for damage or loose contacts. Also, verify that the supply voltage is within the specified range and that the unit is not exposed to condensation.
