50 Gallon HWRL-50 ProLine Master Atmospheric Vent Residential Gas Water Heater Short Model (NG)

This model has side mounting recirculating taps. The ProLine Master family of gas water heaters offers a wide range of water heating solutions, all with a commercial-grade, wholesale-focused design. All A. O. Smith products use Coregard™ stainless steel core anode rods, but the ProLine Master Series has increased anode protection with either larger or multiple anodes depending on model. Ultra-low NOx units are available where required. Features: The internal microprocessor provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance. Uses a thermopile to generate the power needed to operate the electronic gas control without requiring an external power source. The electronic gas control incorporates an LED status indicator that monitors system operation and service diagnostics. Our anode rods have a stainless steel core that extends the life of the anode rod allowing superior tank protection far longer than standard anode rods. ProLine® Master products have increased anode protection with either longer, or multiple anodes depending on model. Our residential water heaters have a solid brass, tamper resistant, enhanced-flow, ball type, drain valve. Uses a standard female hose fitting that allows for fast and easy draining during maintenance. Designed for easy operation, this valve includes an integral screwdriver slot that features a 1/4 turn (open/close) radius, which not only permits full straight-through water flow but also a quick and positive shut off.
