De Dietrich Tube ignition burner 85185514

The De Dietrich 85185514 is a tube ignition burner designed for sectional boilers with 3, 7, or 10 sections. It houses the ignition electrode and feeds the pilot burner, delivering the spark into the air-fuel mixture. This component is part of the burner assembly on the front plate and is specific to De Dietrich boilers.

Parts of this type are selected by the number of boiler sections, as the tube length and sometimes the mounting flange or thread differ with each section count. The tube material and sealing method must be compatible with the burner head and boiler front plate. Before ordering, verify the section count and brand compatibility. After installation, check the electrode gap and insulation.

When items of this kind fail, common issues include cracks, distortion, or carbon deposits on the tube, which can affect electrode position or flame shape. This may result in weak or no spark, leading to ignition failure or unstable flame. Inspect the tube for these signs and verify the electrode gap and insulation.
