The Wacker Neuson Rear Cover is a genuine OEM component designed for the HI260, HI1000, HI1000DGM, Pureheat, and E1100 series indirect air and hydronic heaters. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces. Fitment spans gas, diesel, and DGM variants across the HI1000 family, as well as Pureheat hydronic oil and gas burner units and E1100 ground heaters. When your rear cover is cracked, warped, or missing, replacing it promptly protects internal burner components and maintains proper airflow and heat containment.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring correct fitment and the same service life as the factory-installed cover.
- Broad Heater Family Coverage — A single part number covers HI260, HI1000, HI1000DGM, Pureheat (oil and gas burner), and E1100 series units, including diesel, gas, and electric brake configurations.
- Drop-In Replacement — Mounts using the same attachment points as the original, allowing straightforward removal and reinstallation without modification to the heater housing.
- Heat and Weather Resistance — Engineered to withstand the thermal cycling and outdoor exposure typical of indirect-fired and hydronic heaters used in construction-site cold-weather applications.
- Protects Critical Burner Components — A properly sealed rear cover maintains the intended combustion airflow path and shields internal components from debris and moisture intrusion that can cause premature failure.
- Verified OEM Part Number — Part number 5000194021 matches Wacker Neuson's official parts documentation, so you can order with confidence that this is the correct part for your machine.
The rear cover on an indirect air or hydronic heater serves as the structural closure at the back of the heater housing, enclosing the burner assembly and helping to direct combustion air and exhaust through the correct internal pathways. It also acts as a physical barrier against wind, moisture, and jobsite debris that could interfere with burner operation or damage internal components. When the rear cover is damaged or absent, combustion efficiency drops, heat output becomes inconsistent, and sensitive components inside the housing are exposed to conditions they are not designed to handle — leading to more extensive and costly repairs.
