Bard part 171-203 is an OEM heat exchanger used in Bard DCC gas heating applications, designed to safely transfer heat from the burner section into the supply airstream while keeping combustion gases separated from the conditioned air. When a heat exchanger is cracked, leaking, or heat damaged, replacing it with the correct factory part is critical for proper draft, dependable ignition and heating performance, and safe operation. Because Bard heat exchanger fit and burner configuration can vary by unit size and series, confirm 171-203 against your Bard model and serial number (or the unit parts list) before ordering to ensure correct match.
Please call for available options or find replacement parts.
