Bard 9045-043 - Heat Exchanger Assembly OS140

Bard 9045-043 is an OEM heat exchanger assembly (OS140) used in Bard gas heat wall-mount units to safely transfer burner heat into the airstream while keeping combustion gases sealed from the supply air. Replacing a damaged or rusted heat exchanger helps restore proper heating capacity and supports safe operation by maintaining correct draft and combustion performance. Because heat exchanger fit and firing rate vary by unit size and burner configuration, confirm compatibility by matching the full Bard model and serial information and referencing the unit parts list before ordering Bard 9045-043.
