Bard 171-207 - Heat exchanger for DCH036

Bard part number 171-207 is an OEM heat exchanger specified for Bard DCH036 gas furnace assemblies, and it is the core component that transfers combustion heat into the supply airstream while keeping flue gases separated for safe, efficient heating. When a DCH036 unit shows signs of a compromised heat exchanger, such as abnormal burner behavior, soot, or failed safety checks, replacing with the correct Bard heat exchanger is critical for proper draft, temperature rise, and reliable limit operation. Because DCH-series configurations can vary by model and revision, confirm compatibility by matching the full unit model and serial information to the appropriate Bard parts list or service literature before ordering 171-207.
