The Wacker Neuson Inner Exhaust Stack Complete is a genuine OEM component designed for the S3000 Hydronic Surface Heater series, including the S3000 with 3,000 ft hose and the S3000 with Generator and 3,000 ft hose configurations. As a direct OEM replacement, the is manufactured to the exact material and dimensional specifications of the original part, ensuring a correct, no-compromise installation in your Wacker Neuson HSH unit. Keeping the exhaust stack in good working condition is critical to safe heater operation — a damaged or deteriorated inner stack can compromise combustion venting and create unsafe working conditions on the job.
Key Features
- Genuine OEM Combustion-Grade Construction — Manufactured from materials rated to withstand the sustained heat and thermal cycling specific to hydronic surface heater exhaust systems, matching the durability of the original stack assembly.
- Complete Assembly for Straightforward Swap-Out — Supplied as a complete inner stack unit, so all working components install together in a single service step without sourcing separate sub-pieces.
- Confirmed Fit for S3000 HSH Models — Verified for the S3000 Hydronic Surface Heater with 3,000 ft hose and the S3000 Hydronic Surface Heater with Generator and 3,000 ft hose — cross-check your model number before ordering.
- Maintains Proper Exhaust Flow — A correctly fitted inner exhaust stack channels combustion gases out of the heater efficiently, supporting stable burner performance and consistent heat output across the hose network.
- Critical Safety Component — Exhaust Integrity Matters — A cracked, corroded, or loose inner stack can allow exhaust gases to escape into the surrounding work area. Replacing a worn stack promptly keeps ventilation pathways sealed and the work environment safe.
The inner exhaust stack is the interior lining of the heater's exhaust outlet assembly, responsible for directing hot combustion gases away from the burner chamber and safely out of the unit. In a hydronic surface heater like the S3000, the burner runs continuously during curing and thawing operations, meaning the exhaust stack is exposed to prolonged high-heat cycles that can cause warping, cracking, or corrosion over time. A failed or deteriorating inner stack disrupts proper draft, reduces burner efficiency, and can allow exhaust gases to leak — making timely inspection and replacement an important part of routine heater maintenance.
