The Bard 9043-343 heat exchanger assembly (4016004) is an OEM combustion-side replacement used in Bard gas heating wall mount equipment to safely transfer heat into the airstream while keeping flue gases contained. If your unit is showing signs of heat exchanger failure such as reduced heat output, nuisance safety trips, or a failed inspection due to cracking or leakage, replacing the heat exchanger with the correct Bard factory assembly helps restore proper heat transfer, burner to exchanger alignment, and overall furnace reliability. Because heat exchanger fit and venting components vary by model and serial range, match Bard 9043-343 to your specific unit data plate or parts list before ordering to ensure correct application.
Please call for available options or find replacement parts.
