• Heat Exchanger Assy 100K

Bard S171-245 is an OEM 100,000 BTU heat exchanger assembly used in Bard wall mounted gas electric units, built to restore safe and efficient heat transfer from the burner section into the supply air stream. A correct heat exchanger fit is critical for proper combustion airflow, temperature rise, and reliable limit control operation, so this assembly is a smart choice when addressing a failed heat exchanger or completing a furnace section rebuild on compatible Bard equipment. Verify the exact unit model and serial number against the Bard parts list before ordering, since heat exchanger assemblies can vary by cabinet size and burner configuration even within similar series.
