Bard part 9043-345 is an OEM heat exchanger assembly (manufacturer reference 4016005) used in Bard wall mounted gas/electric equipment to safely transfer combustion heat into the supply airstream while keeping flue gases isolated from occupied air. When a heat exchanger is cracked, restricted, or leaking, it can cause nuisance limit trips, poor heating output, or unsafe operation, so replacing it with the correct Bard factory assembly helps restore proper heat transfer and designed airflow and combustion performance. Because fit and burner configuration can vary by unit series and heat size, confirm the full model and serial number from the unit nameplate before ordering 9043-345 to ensure correct application.
