Bard 521-356 Heat Exchanger Partition Assy is an OEM internal sheet metal partition used in Bard wall-mounted HVAC equipment to separate and guide airflow through the heat exchanger section. A properly fitted partition helps maintain correct air path and prevents air bypass that can reduce heating performance, create uneven temperatures, or contribute to nuisance limit trips. If your original partition is damaged, rusted through, or has been removed during prior service, replacing it with the correct Bard 521-356 assembly helps restore the intended airflow separation and supports reliable unit operation; verify compatibility by matching your unit model and serial number to the Bard parts list before ordering.
