Rheem-Ruud AS-104120-15 Heat Exchanger Assembly

Rheem-Ruud AS-104120-15 Heat Exchanger Assembly is an element of a furnace that is used to exchange heat of combustion gases with circulating air in residential gas furnaces in HVAC systems. It operates by letting the hot flue gases travel through internal passages as the air proceeds over the exchanger surface which permits the transfer of heat without mixing air streams. Constructed as a whole unit, it is installed in the furnace cabinet and is linked to the burner and blower units to work together. This facilitates constant heat production, assists in maintaining the temperature and proper separation of combustion gases and indoor airflow.
