The Wacker Neuson Exhaust Pipe is a genuine OEM component designed for the HI 770 XHD indirect-fired air heater series. Sourced directly from Wacker Neuson, this exhaust pipe is engineered to match the original installation geometry and thermal tolerances of the HI 770 XHD platform, covering diesel-powered configurations including 2x12, 1x16, and 1x20 ducting arrangements, as well as Arctic Bear XHD and Arctic Bear XHD NS variants. As a genuine OEM part, it carries the same specifications as the component that shipped with your machine — no guesswork on fitment or material grade. Confirmed fitment spans the full HI 770 XHD lineup, making the correct choice for a direct, like-for-like replacement on these heavy-duty heating units.
Key Features
- Genuine OEM Heat-Rated Construction — Manufactured to withstand the continuous exhaust temperatures produced by the HI 770 XHD's diesel combustion system, matching the original pipe's material spec and wall integrity.
- Drop-In Fitment for HI 770 XHD Configurations — Matches the original mounting points and outlet dimensions across 2x12, 1x16, and 1x20 duct configurations for a straightforward swap.
- Broad HI 770 XHD Series Coverage — Fits standard HI 770 XHD diesel units as well as Arctic Bear XHD and Arctic Bear XHD NS cold-weather variants across multiple machine numbers.
- Maintains Clean Combustion Exhaust Routing — A sound exhaust pipe keeps combustion gases directed safely away from the heat exchanger and air stream, preserving output efficiency and heater performance in demanding winter conditions.
- Critical Safety Component for Indirect Heating Units — The exhaust pipe is part of the sealed combustion circuit that separates combustion gases from the conditioned air output; a cracked or leaking pipe compromises both heater performance and on-site air quality.
The exhaust pipe on an indirect-fired air heater routes combustion gases from the diesel burner assembly out of the unit while keeping them fully isolated from the heated air delivered to the workspace. Because the HI 770 XHD operates as an indirect heater, clean air separation between the flue path and the conditioned air stream is essential — any breach in the exhaust pipe can allow combustion byproducts to contaminate the output airflow. A damaged or corroded exhaust pipe can also disrupt back-pressure balance in the combustion chamber, reducing burner efficiency and triggering fault shutdowns.
