Choosing and fitting
Parts of this type are selected by matching the series and type designation, supply voltage, safety time, pre-purge time, and flame detection method. The physical base or plug pattern must match the existing wiring harness. Verify the markings on the original control and consult the burner manufacturer's specification before ordering.
Signs of failure
