• Heat Exchanger Assy 50K

Bard S171-273 is a genuine OEM heat exchanger assembly rated for 50,000 BTU input, used in Bard wall-mounted gas/electric package units to safely transfer heat from the burner to the supply air stream while keeping flue gases contained. Replacing a compromised heat exchanger is critical for proper combustion, correct temperature rise, and safe operation, and this assembly is built to Bard fit and performance requirements so it installs the way the original was designed to. Because heat exchanger applications can vary by unit series and furnace configuration, confirm compatibility by matching your model and serial information to the correct Bard parts list before ordering Bard S171-273.
