Kromschroder Ionization electrode ZKIH L500 74450314

The Kromschroder ZKIH L500 ionization electrode (SKU 74450314) is a flame rod designed for use in Kromschroder ZKIH L500 pilot burners. It carries the flame signal only, detecting flame presence through ionization. The electrode has a length of 500 mm and is compatible with Kromschroder ZKIH L500 pilot burners. Its article numbers are 74450314 and 624.751.013.

When selecting a replacement ionization electrode of this type, compare the physical shape and dimensions with the original, including the electrode length, bend angle, insulator diameter, gap between the electrode tip and burner body, and mounting flange pattern. These dimensions are specific to the burner series or combustion head design. Always verify the electrode's fit before installation.

Typical failure modes for ionization electrodes include a worn or eroded tip, a crack in the ceramic insulator, soot deposits that short the signal, and a drifting spark gap that delays or prevents ignition. When the electrode fails, the burner control may lock out due to loss of flame signal. Check the condition of the grommet or seal where the electrode passes through the burner plate, and verify that the cable and connector to the burner control are intact.
