- The internal micro-processor 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
- 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
- Dynaclean diffuser dip tube reduces lime and sediment build-up and maximizes hot water output
- 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
- Push button piezo igniter makes lighting the pilot fast and easy with one-hand push-button spark ignition
- Factory installed heat trap nipples for faster installation
- Blue diamond glass coating provides superior corrosion-resistance compared to industry standard glass lining
- 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
- 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
- 6 years limited tank and component parts warranties
- The ProLine 400/401 Series gas water heater is designed to deliver an economical performance that can lower your energy bills and also provide long-lasting value
