    • Introducing the ProLine® XE 50-Gallon Atmospheric Vent Natural Gas Water Heater with Non-Powered Flue Damper--the only high efficiency gas product that does not require electricity. This product uses an inlet air damper underneath the combustion chamber that operates using gas pressure. This damper reduces airflow through the heater during the off cycle or when water is not being heated. Featuring a 50-gallon (nominal) tank and a 40,000 BTU gas burner, the GCD-50 standard vent delivers a first hour rating of 75 gallons and a recovery rate of 40 gallons per hour. This model features a 0.68 Uniform Energy Factor and carries a 6-year limited warranty. Environmentally-friendly insulation and factory-installed heat trap nipples reduce heat loss for maximum energy savings. This ProLine® XE water heater is designed with A. O. Smith's superior commercial-grade tank protection. Advanced tank features include stainless steel Coregard™ anode rod, Blue Diamond® glass lining and DynaClean™ automatic sediment-cleaning system, all designed to help protect the tank from the corrosive effects of water and extend the life of the water heater. This model also includes built-in Dry-Fire protection to protect the heating elements from damage during initial start up. All of these features are accompanied by a 6-year limited tank warranty. A. O. Smith’s ProLine® water heaters are residential products built to commercial-grade standard and are only available for purchase through professional wholesalers and contractors.
