- Direct vent design one-pipe, dual channel closed combustion system draws all make up air from outside the home, eliminating problems caused by insufficient indoor ventilation and is FVIR compliant
- Horizontal air intake and venting on all model up to 80 in from outside the wall with no electrical power needed
- The internal microprocessor provides enhanced operating parameters and tighter differentials for precise sensing and faster heating response to optimize performance
- DynaClean™ diffuser dip tube helps to reduce lime and sediment buildup, maximizes hot water output, made from long-lasting Pex cross linked polymer
- Self-powered electronic gas valve 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
- Green Choice® gas burner, patented eco friendly design reduces NOx emissions and complies with less than 40 ng/J requirements for NOx emissions
- Coregard™ 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
- Pushbutton piezo ignitor makes lighting pilot fast and easy with one hand pushbutton spark ignition
- Heat traps nipples factory installed
- Durable tamper-resistant brass drain valve
- AO Smith® blue Diamond® glass coating provides superior corrosion resistance compared to industry standard glass lining
- Recovery rate is 41 gph at 90 deg F rise
