• HEAT EXCHANGER ASSEMBLY

Bard part 171-169 is an OEM heat exchanger assembly used in Bard wall-mounted gas/electric units to safely transfer burner heat into the airstream while keeping combustion gases contained. In the field, a worn or damaged heat exchanger can cause nuisance limit trips, poor heat output, or unsafe operation, so replacing it with the correct factory assembly is important for proper fit, airflow alignment, and reliable heating performance. Because heat exchanger configurations vary by model and input rating, confirm compatibility by matching your unit model and serial number to the Bard parts literature before ordering 171-169.
