Bard 171-319BX - Heat Exchanger Assembly 125K
Bard part 171-319BX is an OEM 125,000 BTU heat exchanger assembly used in select Bard wall mounted gas/electric units, including WG5SF series applications, and it is the core component that transfers heat from the burner to the supply air stream while keeping combustion gases safely contained. Replacing a cracked or compromised heat exchanger with the correct Bard assembly helps restore safe furnace operation, proper airflow temperature rise, and reliable heat output under factory design conditions. Because heat exchanger fit and venting alignment are model specific, match 171-319BX to your unit data plate and the correct parts breakdown before ordering, then inspect related gaskets and collector box connections during installation to prevent leaks and nuisance limit trips.

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.
