The Wacker Neuson Burner Flange is a genuine OEM component designed for the E 1250S, E 1250P, and E 1250B hydronic surface heaters, as well as the HSH 380S and HSH 380B hydronic surface heater units. As a factory-sourced part, the is manufactured to the same tolerances and material specifications as the original, ensuring a correct, secure mount between the burner assembly and the heater body. Verify your model number before ordering — this flange is confirmed to fit all five variants across the E 1250 and HSH 380 series.
Key Features
- OEM Burner Interface Integrity — Manufactured to the same dimensional and material specifications as the original, maintaining a gas-tight, heat-resistant seal at the burner mounting point.
- Drop-In Burner Mounting — Bolt pattern and flange geometry match the original installation, so the burner assembly seats correctly without modification to surrounding components.
- Broad Series Fitment — Confirmed for the E 1250S, E 1250P, and E 1250B (LP/NG) and the HSH 380S and HSH 380B hydronic surface heater models.
- Sustained Heating Output — A properly sealed burner flange keeps combustion gases directed efficiently through the heat exchanger; a warped or cracked flange can cause uneven heat distribution and combustion inefficiency.
- Fuel System Safety — Because this flange forms part of the sealed combustion path on a gas-fired heater, using a correctly dimensioned OEM replacement helps maintain the integrity of the fuel-to-burner interface and reduces the risk of gas leaks or combustion faults.
The burner flange is the structural and sealing interface that connects the burner assembly to the heater body on LP/NG-fired hydronic surface heaters. It holds the burner in precise alignment with the combustion chamber and forms a gas-tight joint that keeps combustion contained and directed through the heat exchanger. When the flange warps, cracks, or corrodes, the burner can shift out of alignment or allow combustion gases to escape, leading to reduced heating efficiency, uneven heat output, and potential safety concerns on the jobsite.
