The Rheem AS40520 Flue Baffle Assembly is designed to enhance the efficiency of 40-gallon gas water heaters. This part restricts airflow within the flue, extending the combustion gas path. The longer exposure to the heat maximizes transfer to the water in the tank, improving heating efficiency.
This assembly is ideal for maintaining optimal water heater function by enhancing heat transfer.
