Features N/A
  • Bradford White ICON System™ - Intelligent gas control with spark to pilot ignition system eliminates the constant burning pilot. This results in savings of pilot gas during stand by periods (120 V.A.C.).
    • Enhanced Performance - Proprietary algorithms provide 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 startup and provides ten different diagnostic codes to assist in troubleshooting.
    • 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.
  • Compatible with Optional Accessory Packages - Performance Package, Protection Package and Inlet Shut-Off Valve.
  • Power Vented Water Heater - Designed for installations where atmospheric units cannot be used. Exhaust gases are vented under positive pressure directly out of the building through the roof or the wall.
  • Powerful Blower Motor - Our significantly quiet design has greater resistance to outside winds and the power to vent in many difficult venting situations.
  • Horizontal and Vertical Venting - With 3" or 4" PVC, ABS or CPVC (maximum equivalent vent lengths on reverse side).
  • High Input Combustion System - Generates enough hot water in the first hour for whirlpool tubs, garden tubs or body sprays in addition to whole house duty.
  • Integrated Mixing Device - Features an accurate, easy to use hand wheel for adjusting mixed water temperature, a pre-piped stainless steel flexible connector for quick installation as well as optional water connections (1/2" NPT recirculation inlet, 1/2" NPT hot water outlet, 1/4" NPT cold water outlet). This required system is easily installed and ensures a comfortable outlet temperature while providing a steady flow of hot water.
  • Helical Fin Flue - Specifically welded fins slow down the products of combustion, optimizing increased surface area efficiency and the amount of heat transferred to the water.
  • Factory Installed Hydrojet 2™ Total Performance System - Cold water inlet sediment reducing device helps prevent sediment build up in tank.
  • Vitraglas® Lining - Bradford White tanks are lined with an exclusively engineered enamel formula that provides superior tank 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 1600 ºF.
  • 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.
  • Pedestal Base.
  • Water Connections 3/4" NPT factory installed true dielectric fittings.
  • 3/4" NPT Side Connections.
  • Factory Installed Heat Traps - Design incorporates a flexible disk that reduces heat loss in piping and eliminates the potential for noise generation.
  • Two Protective Magnesium Anode Rods.
  • T&P Relief Valve - Installed.
  • Low Restriction Brass Drain Valve - Durable tamper proof design.
General Information N/A All gas water heaters are certified at 300 psi test pressure (2068 kPa) and 150 psi working pressure (1034 kPa). All water connections are 3/4" NPT (19 mm) on 8" (203 mm) centers, all gas connections are 1/2" (13 mm).
