Bard S171-208 is an OEM service heat exchanger designed for Bard FH085 gas heat sections with A through D suffix variations, providing the sealed combustion heat transfer surface needed to deliver reliable, safe furnace heating and proper flue gas handling. As a critical mechanical component, this heat exchanger is built to Bard specifications to restore correct airflow temperature rise and heat output when the original exchanger is damaged, leaking, or fails inspection. Confirm your unit model and the FH085 A-D suffix match before ordering, since heat exchanger fit is tied to the exact heater configuration and serial range.
* Orders less than $50 may incure a minimum order fee.
