Description
The Rheem-Ruud AS-90645-14 is an OEM replacement heat exchanger designed for use in compatible Rheem and Ruud heating systems. As a critical component of your furnace, the heat exchanger is responsible for transferring heat from the combustion process to the air supply while keeping combustion gases safely separated from conditioned air.
