High-Input Direct Vent (DH) water heaters offer greater recovery capabilities, larger gallon capacities and side connections for space heating. They utilize a co-axial (pipe inside a pipe) venting system. No electricity required.

  • Flexible Vent Kit - The maximum vent length (horizontal and vertical) can be flexed to 100" (horizontal termination only).
  • 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.
    • Closed Combustion - All air for combustion is taken directly from the outside. The co-axial vent pipe (pipe inside a pipe) draws combustion air in through the outer pipe (6"), and exhausts the products of combustion through the inner pipe (4"). The co-axial vent pipe at the top of the unit can be rotated for venting flexibility.
    • Reinforced Seals - Seals surround the closed combustion chamber and the FVIR inner door, preventing the ignition of Flammable Vapors outside of the water heater.
    • Maintenance Free - The vent piping and the closed combustion chamber with reinforced seals does not require regular cleaning under normal operating 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.
    • Cast Aluminum Air Intake Boot - A cast molded air intake boot provides exceptional installation durability.
    • Side Connections - 3/4" NPT tappings allow easy connections for space heating applications (Potable water only).
    • 1" Non-CFC Foam Insulation - Surrounds the tank surface, saving energy by reducing the amount of heat loss.
    • Pedestal Base.
    • Water Connections - 3/4" NPT factory installed true dielectric fittings.
    • Factory Installed Heat Traps.
    • Protective Magnesium Anode Rod.
    • T&P Relief Valve - Included.
    • Brass Drain Valve - Tamper proof design.
