Item Features
Intelligent control logic - 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 and LED status indicator that monitors system operation and service diagnostics
DynaClean™ diffuser dip tube - Reduces lime and sediment buildup and maximizes hot water output
Made from long-lasting PEX cross-linked polymer
Green Choice® gas burner - Patented eco-friendly burner design reduces NOx emissions by up to 33% and complies with Low-NOx emission requirements of less than 40 ng/J
Coregard™ anode rod - 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 rod
ProLine® master products have increased anode protection with either longer or multiple anodes depending on model
Push button piezo igniter makes lighting the pilot fast and easy with one hand
Heat trap nipple - Factory installed for faster installation
Blue Diamond® glass coating - Provides superior corrosion resistance compared to the industry standard glass lining
Blue Diamond® glass coating blend is formulated in the same lab that creates the protection for our industry-leading commercial product line
Enhanced-flow brass drain valve - 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
High uniform energy factor - Eco-Friendly non-CFC foam insulation, external heat traps and specially designed combustion chamber combine to produce a high UEF for maximum savings on operating costs
All models approved for installation from sea level to 10100 ft elevation
