Bard 171-307BX - Heat Exchanger Assembly 90K
The Bard 171-307BX heat exchanger assembly (90K) is an OEM replacement component used in select Bard wall mounted heating and cooling units to safely transfer heat from the burner side into the supply airstream during heating operation. When a heat exchanger is cracked, leaking, or failing inspection, replacing it with the correct Bard factory assembly helps restore proper heat output, supports stable temperature rise, and keeps the unit operating within its intended safety limits. Because fit and venting details vary by model and revision, match 171-307BX to your Bard unit model and serial number before ordering to ensure proper compatibility and a straightforward 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.
