The Atmospheric Vent FVIR Defender Safety System Models Feature: ■ Bradford White ICON System—Intelligent control with proven millivolt powered technology and built-in piezo igniter. A standard, off the shelf thermopile converts heat energy from the pilot flame into electrical energy to operate the valve and microprocessor. No need for external electricity. -- Enhanced Performance—Proprietary algorithms provide enhanced First Hour Delivery ratings and tighter temperature differentials. -- Advanced Temperature Control System—Microprocessor constantly monitors and controls burner operation to maintain consistent and accurate water temperature levels. -- Intelligent Diagnostics—An exclusive green LED light prompts the installer during start-up and provides ten different diagnostic codes to assist in troubleshooting. -- Pilot On Indication—Flashing green LED provides positive indication that pilot is on. -- Separate Immersed Thermowell—High-strength advanced polymer composite thermowell provides isolation between electric temperature sensor and surrounding water. No need to drain the tank when removing valve. ■ Advanced ScreenLok Technology Flame Arrestor Design—Flame arrestor is designed to prevent ignition of flammable vapor outside of the water heater. ■ Resettable Thermal Switch—Proven and reliable bimetallic switch prevents burner and pilot operation in case of ongoing flammable vapor burn inside of the combustion chamber or restricted air flow. ■ Maintenance-Free—No regular cleaning of air inlet openings or flame arrestor is required under normal conditions. ■ Window—Offers a view into the combustion chamber to observe the operation of the pilot and burner. ■ Factory-Installed Hydrojet Total Performance System—Cold water inlet sediment reducing device helps prevent sediment build-up in tank. Increases first hour delivery of hot water while minimizing temperature build-up in tank.
