Bard 171-273BX - 50K Heat Exchanger Assembly
The Bard 171-273BX is an OEM 50,000 BTU heat exchanger assembly used in Bard wall mounted gas/electric equipment to transfer combustion heat into the supply airstream while keeping flue gases isolated for safe, efficient heating. When a heat exchanger is cracked, restricted, or shows signs of corrosion, replacing it with the correct factory assembly helps restore proper temperature rise, stable burner operation, and reliable limit control performance. This part is intended to match Bard specified fit and airflow path within the heater section, so confirm your unit model and serial to ensure the 171-273BX is the correct 50K heat exchanger service replacement for your application.

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.
