• Heat Exchanger For F86H

Bard part number 171-116 is an OEM heat exchanger specified for the Bard F86H gas furnace section, designed to safely transfer heat from the burner flame to the airstream while keeping combustion gases isolated from the supply air. If your unit has a cracked or leaking exchanger, replacing it with the correct factory part helps restore proper heat output, stable combustion, and safe operation without fitment guesswork. Because heat exchangers can vary by furnace series and revision, confirm your full model and serial number (and any kit or assembly notes in the parts list) before ordering to ensure the right match for your F86H configuration.
