  • 171-125 OBSOLETE

  • HEAT EXCHANGER FOR IC115

Bard part number 171-125 is an OEM heat exchanger specified for IC115 equipment, replacing the core component that transfers heat from the burner side into the airstream while keeping combustion gases sealed from supply air. When a heat exchanger is cracked, restricted, or leaking, it can cause nuisance limit trips, poor heating output, or unsafe operation, so replacing it with the correct Bard factory part is critical for proper fit, flue alignment, and safe heating performance. Because heat exchanger configurations can vary by IC115 revision and gas heat package, confirm the full model and serial number and compare the original exchanger layout before ordering to ensure the correct match.
