  • Heat Exchanger For Fh085

Bard part number 171-178 is an OEM heat exchanger specified for Bard FH085 furnaces. The heat exchanger is the sealed combustion component that transfers heat into the airstream while keeping flue gases isolated, so proper fit and correct replacement are critical for safe, efficient operation. Using the correct Bard factory part helps ensure the burner and venting system geometry stays as designed, which supports reliable ignition, stable heat output, and correct airflow through the heat section. Confirm your exact FH085 model and configuration before ordering, since heat exchanger designs can vary by series and revision, and always follow Bard service literature and qualified HVAC procedures during installation and startup checks.
