What to do if my Dunkirk DCB-165 has ignition failure?
- RRyan HessAug 21, 2025
If your Dunkirk Boiler experiences ignition failure, begin by inspecting the condensate trap for proper operation. Then, check the sensing electrode, spark electrode, and cable. Ensure there is no flue recirculation and verify electrical continuity between the burner and the ground. Examine the gas orifice and gas pressure. If necessary, perform automatic and manual calibration functions.
