The Wacker Neuson Exhaust Manifold is a genuine OEM component designed for HI 770 XHD and Arctic Bear XHD series indirect air heaters. Sourced directly from Wacker Neuson, this part carries the same specifications as the original — ensuring a correct, trouble-free installation without guesswork. It is confirmed to fit across multiple HI 770 XHD and Arctic Bear XHD configurations, including diesel variants built for demanding heating applications on the jobsite.
Key Features
- OEM-Spec Exhaust Sealing: — Cast and machined to original tolerances, this manifold maintains a gas-tight seal at the combustion outlet — critical for safe and efficient heater operation.
- Direct Bolt-On Installation: — Matches the original mounting flange pattern and port dimensions, so it installs directly in place of the factory part with no reworking of hardware or brackets.
- Broad HI 770 XHD and Arctic Bear XHD Coverage: — Fits multiple model configurations across the HI 770 XHD and Arctic Bear XHD indirect air heater families, including single- and dual-outlet diesel variants.
- Restores Full Heat Output: — A cracked or warped exhaust manifold causes combustion gases to escape before the heat exchanger, robbing the unit of output. This OEM replacement brings the heater back to its rated heating capacity.
- Combustion Integrity and Operator Safety: — On indirect-fired heaters, a compromised exhaust manifold can allow combustion byproducts to contaminate the heated air stream. Replacing a failed manifold with a genuine OEM part restores the separation between exhaust gases and the clean air supply.
The exhaust manifold collects combustion gases from the burner assembly and routes them away from the heat exchanger and out of the unit. In an indirect-fired heater, this separation is essential — it keeps exhaust gases isolated from the clean, heated air that is delivered into the work space. When the manifold cracks, warps, or develops a leak, exhaust gases can bypass the intended flow path, reducing heat output and potentially introducing harmful emissions into the heated airstream. Replacing a worn manifold promptly keeps the heater running at full efficiency and maintains the air quality separation that indirect heaters are specifically designed to provide.
