York S1-373-12894-704 Heat Exchanger

If you're out in the field dealing with a cracked primary and facing rollout issues on a York or Coleman furnace, the York S1-373-12894-704 Heat Exchanger is the exact OEM component required for a safe return to service. This 4-tube heat exchanger is engineered specifically for direct-fit compatibility in various B2HN gas furnace models and Coleman Evcon residential units. Constructed with high-grade, corrosion-resistant materials, these OEM York furnace parts are designed to handle the high-temperature combustion stresses that often lead to recurring pinhole leaks or seam failures in aftermarket alternatives. Swapping in a genuine York S1-373-12894-704 ensures that the combustion blower and manifold alignment remain within factory tolerances, maintaining efficient thermal transfer and preventing dangerous carbon monoxide bypass into the airstream. For a heat exchanger replacement, this heavy-duty assembly provides the structural integrity needed to withstand the rigors of seasonal cycling in varied climates.

• Direct OEM Compatibility: Verified fit for York, Coleman, and Evcon gas furnaces, eliminating the need for field modifications.
• Superior Metallurgy: High-quality construction resistant to industrial-level thermal stress and acidic combustion byproducts.
• Optimized 4-Tube Geometry: Precision-formed 4-tube heat exchanger design maximizes surface area for efficient airflow heating.
• Enhanced Safety: Seamless construction prevents cracked cells, ensuring a strict boundary between flue gases and indoor air.

Common Questions

What are the signs that this 4-tube heat exchanger needs replacement?
Technicians should look for soot buildup, unusual odors, or visible cracks during a combustion analysis. If you detect CO in the supply air or observe a dancing flame when the blower kicks on, a heat exchanger replacement is mandatory for safety.

Is this part compatible with Coleman or Evcon units?
Yes, the York S1-373-12894-704 is a cross-compatible OEM part often found in Coleman-Evcon B2HN series furnaces. Always verify the part number against the unit’s data plate before installation.

Does this assembly include the necessary gaskets for installation?
This item typically consists of the heat exchanger assembly; we recommend sourcing a secondary gasket kit and high-temp sealant to ensure a gas-tight seal at the collector box and manifold mounting surfaces.
