Bard 171-315BX - Heat Exchanger Assembly 75K
The Bard 171-315BX is an OEM 75,000 BTU heat exchanger assembly used in select Bard wall mounted gas/electric packaged units, where it transfers heat safely from the burner to the supply air stream while keeping combustion byproducts isolated from the conditioned air. If you are troubleshooting a cracked, leaking, or restricted heat exchanger, replacing the complete assembly helps restore proper heat output, stable ignition and combustion performance, and safe operation to Bard specifications. Match this part number to the unit model and the parts list for your exact series before ordering, since heat exchanger assemblies are model specific and may require reusing or transferring related hardware and seals per the service instructions.

What does the "BX" suffix mean?
Bard uses suffixes like "BX" to manage parts internally. These do not change the physical form or function of the part.
A part number ending in "BX" simply means it is packaged in a box for shipping, rather than for internal assembly use.
Example: 8406-142BX is physically identical to 8406-142.
