171-138 OBSOLETE
- HEAT EXCHANGER FOR IH85
Bard part number 171-138 is an OEM heat exchanger assembly used in Bard IH series gas furnace equipment, including the IH85D48B as shown in the Bard parts manual. This is the primary heat transfer component that keeps combustion gases separated from the air stream while delivering steady, safe heat to the supply air. When a heat exchanger is cracked, restricted, or heat stressed, replacement is critical for proper draft, efficient heat transfer, and safe operation. Because fit and venting alignment are model specific on these furnaces, confirm the full unit model and serial number before ordering to ensure Bard 171-138 is the correct match for your IH85 configuration.
