Professional Collection 50000 Max BTU Input Residential Natural Gas Powered Damper Water Heater with Tall 50 Gallon Tank

Powered Damper

Sitting atop the water heater is a 24 volt powered flue damper. It opens and closes automatically in response to gas-burner activity. When combustion stops the damper closes, trapping heat inside the flue and delivering more heat to the water.

Guardian Systemâ„¢

Rheem's Guardian System provides double protection, shutting off both air and fuel systems should it detect the presence of flammable vapor accumulation. This system is also maintenance free with no filter to clean.

Longer Tank Life

Standard anode rods help protect water heater tanks from rust. This unit uses a patented magnesium anode rod design that incorporates a special resistor, resulting in longer tank life.

Low Emissions

Eco-friendly burner is a low nitrous oxide emission design, meeting 40 ng/J emission requirements
