Bard part 171-297BX is an OEM 100,000 BTU heat exchanger assembly used in select Bard gas heating sections to transfer heat safely and efficiently into the supply airstream while keeping combustion gases isolated. If you are troubleshooting rollout, corrosion, cracks, or reduced heating output, replacing the heat exchanger with the correct factory assembly helps restore proper temperature rise and dependable operation. Since heat exchangers are model and serial specific, confirm the exact unit match before ordering to ensure correct fit, venting alignment, and safe performance.
* Orders less than $50 may incure a minimum order fee.
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.
