• Heat Exchanger Assy 125K

Bard S171-301 is an OEM 125K BTU heat exchanger assembly used in Bard wall mounted gas electric equipment to transfer burner heat into the supply airstream while keeping combustion gases isolated from indoor air. Replacing a worn or damaged heat exchanger can help restore proper heat output, safe operation, and reliable ignition and burner performance on compatible Bard units. Because heat exchangers are model and capacity specific, confirm your unit model and serial, fuel type, and heat input rating match the required 125K application before ordering, and replace any required gaskets or seals per the Bard service literature during installation.
