171-143 OBSOLETE
- HEAT EXCHANGER C140 & C160
Bard part number 171-143 is an OEM heat exchanger specified for Bard C140 and C160 gas heating sections, built to transfer heat safely from the burner flame into the supply airstream while keeping combustion gases sealed within the exchanger. If your unit has a cracked or leaking exchanger, shows rollout issues, or trips safety limits, replacing the exchanger with the correct Bard assembly is the right way to restore dependable heating performance and maintain proper venting and combustion safety. Because heat exchangers are model and revision sensitive, confirm your exact unit model and serial number against the Bard parts list or service manual before ordering to ensure correct fit and burner section compatibility.
