Bard 917-315BX is an OEM heat exchanger assembly rated at 75,000 BTU, used in gas heating sections on select Bard wall-mounted HVAC units to transfer heat safely into the supply air stream. When a heat exchanger is cracked, leaking, or heat-stressed, replacing it with the correct factory assembly helps restore proper temperature rise, reliable ignition and flame stability, and safe operation under normal combustion airflow. Because fitment can vary by unit series and build configuration, confirm compatibility using the complete Bard model and serial number before ordering Bard 917-315BX.
