Giersch Ignition electrode set (pair: left + right) with mounting bracke 47-90-22421

Giersch ignition electrode set (pair: left + right) with mounting bracket, SKU 47-90-22421, type designation MG20-ZM-L-LN. This set is designed for Giersch MG20-LN gas burners. It consists of two electrodes with ceramic insulation and heat-resistant corrosion-resistant alloy bodies. The set provides a high-voltage spark for ignition and is resistant to soot and extreme temperatures.

When selecting electrodes of this type, verify that the electrode shape, insulator dimensions, and mounting bracket match the original part. The spark gap and the type of mounting flange must correspond to the burner model. Measure the length and bend of the rod, and the diameter and length of the ceramic insulator before ordering.

Typical failure modes include eroded or carbonised tips, cracked insulators causing premature grounding, heavy sooting that insulates the ionisation signal, and drift in the spark gap that lengthens ignition time. Equipment may fail to ignite or lock out after repeated start attempts.
