S171-297 OBSOLETE
- Heat Exchanger Assy 100K
The Bard S171-297 heat exchanger assembly is an OEM 100K BTU furnace heat exchanger used in select Bard wall-mounted gas/electric HVAC units, where it separates combustion gases from the supply air stream to deliver safe, consistent heating performance. If your unit has a cracked or leaking heat exchanger or has failed inspection, replacing with the correct Bard factory heat exchanger helps restore proper draft and temperature rise while maintaining the original fit with the burner and collector components. Confirm unit model and serial compatibility before ordering, since Bard heat exchanger part numbers are application-specific across WG and W-series configurations.
