The Wacker Neuson Inner Exhaust Stack Complete is a genuine OEM component designed for the HSH hydronic surface heater series, including the HSH700G, HSH650, E2200, E3000 ES, E700M, and related ground heater configurations. As a direct OEM replacement, part is manufactured to the same specifications as the original, ensuring a correct installation with no fitment uncertainty. This part covers a wide range of E2200 and E3000 ES variants — including models HSH700G, E2200, E3000ES, HSH650, E3000, E700M.
Key Features
- Genuine OEM Exhaust Integrity — Manufactured by Wacker Neuson to match the original exhaust stack geometry, ensuring proper combustion gas routing and sealed stack alignment within the heater housing.
- Direct-Fit Replacement — Engineered to drop into the existing stack assembly position on compatible HSH and E-series ground heater units without requiring modification to surrounding components.
- Broad HSH Series Compatibility — Confirmed fitment across HSH700G, HSH650, E2200 (multiple configurations), E3000 ES, and E700M hydronic surface heaters, covering both ground heater and hydronic surface heater variants.
- Combustion Performance — A correctly seated inner exhaust stack maintains proper draft and exhaust flow, allowing the burner to operate at consistent output temperatures — critical for effective ground thawing and concrete curing applications.
- Safety-Critical Exhaust Component — The inner exhaust stack contains and directs combustion gases away from the unit's heat exchanger and operator environment; a cracked, corroded, or improperly seated stack can allow exhaust gases to escape into the work area and should be replaced promptly.
The inner exhaust stack is the interior flue section that channels hot combustion gases from the burner through and out of the heater unit. It works in conjunction with the outer stack assembly to create a controlled exhaust path, maintaining the separation between outgoing exhaust gases and the clean air supply or heated output. When the inner stack is damaged, corroded, or develops gaps at its joints, exhaust gases can bypass the intended flow path — reducing heating efficiency, triggering operational faults, and creating potential exposure hazards for workers in the vicinity of the heater.
