• HEAT EXCHANGER ASSEMBLY

The Bard 171-170 heat exchanger assembly is an OEM replacement component used in Bard gas heating sections to transfer heat safely and efficiently into the supply airstream while keeping combustion byproducts contained within the heat exchanger. If your unit is showing signs of a cracked or failing exchanger, such as unusual odors, soot, rollout issues, nuisance limit trips, or poor heating performance, replacing the heat exchanger is a critical repair for both safety and reliability. Because heat exchanger designs vary by model and input rating, confirm compatibility by matching Bard 171-170 to your unit model and serial number information and the correct parts list before ordering to ensure proper fit and restored factory operation.
