Bard 171-254BX - 45K Heat Exchanger Assembly
The Bard 171-254BX is an OEM heat exchanger assembly for 45,000 BTU gas heat sections used in select Bard wall mounted gas/electric packaged units. This is the primary combustion side heat transfer component that safely moves heat into the supply airstream while keeping flue gases isolated, helping restore proper heating capacity and reliable operation when a cracked, leaking, or damaged exchanger needs replacement. Because heat exchanger fit and burner configuration vary by model and series, match 171-254BX to the exact unit model and serial in the Bard parts list before ordering, and plan to follow manufacturer startup and safety checks after installation.

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.
