Choosing and fitting
Replacement control boxes of this kind must be selected by matching the exact series and type designation, as well as the supply voltage, safety time, and pre-purge time of the existing unit. The flame detection method — ionization electrode, UV scanner, or IR detector — must be compatible with the sensor in use. Different series are intentionally not interchangeable even within the same brand, and a mismatched safety time creates a hazardous condition. Also compare the mounting form: these controls are either mounted on a base or plugged into a matching connector, so the wiring base pattern must correspond.
