Description
The De Dietrich Surface igniter Q3271R1007B is an ignition electrode used in De Dietrich DTG 220 ECONOX and DTG 210 NEZ boilers. It is resistant to combustion products and soot. This item supersedes part numbers 83688793 and 83774701. It delivers the spark that ignites the fuel in medium and high power boilers.
Choosing and fitting
Parts of this type are selected by matching the electrode length and bend, insulator diameter, spark gap, mounting flange dimensions, and the burner series for which the electrode was shaped. Before ordering, compare these parameters with the existing electrode. Mounting forms may vary, so ensure the flange fits the burner.
Signs of failure
Typical failure modes include an eroded or sooted tip, a cracked ceramic insulator, and a drifting gap that lengthens ignition time. When the electrode fails, the burner may not ignite or may have delayed ignition. Check the electrode tip for wear, the insulator for cracks, and the spark gap.
