Bradford White Atmospheric Vent M-I-403S6FBN , 40Gal , 40,000 BTU

Features:
Bradford White ICON System – Intelligent gas 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 gas 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 gas 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.
Sight 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.
Vitraglas® Lining – Bradford White tanks are lined with a exclusively engineered enamel formula that provides superior protection from the highly corrosive effects of hot water. This formula (Vitraglas®) is fused to the steel surface by firing at a temperature of over 1600ºF.
1″ Non-CFC Foam Insulation – Covers the sides and top of tank, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies and jacket rigidity.
