  • Features
  • Videos
  • 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 VAC)
  • 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
  • Automatic flue damper - Reduces stand-by heat loss, resulting in less gas consumption, higher energy factor ratings, and improved overall efficiency
  • Advanced ScreenLok® technology flame arrestor design - Flame arrestor is designed to prevent ignition of flammable vapor outside of the water heater
  • Flammable vapor sensor - Electronic sensor prevents burner operation if flammable vapors are detected
  • 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 - Sediment reducing device that also increases first hour delivery of hot water while minimizing temperature build up in tank
  • Vitraglas® lining - 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 deg F
  • Insulation system - Non-CFC foam covers the sides and top of the tank, reducing heat loss, this results in less energy consumption, improved efficiencies and jacket rigidity
  • Pedestal base
  • Water connections - 3/4 in NPT factory installed true dielectric fittings extend water heater life and simplify water line connections
  • Factory installed heat traps - Design incorporates a flexible disk that reduces heat loss in piping and eliminates the potential for noise generation
  • Protective magnesium anode rod
  • 3 x 4 in "Snap Lock" draft diverter
  • Low restrictive brass drain valve - Durable tamper proof design
  • Standard/Approvals: AHRI Certified, ANSI Z21.10.1, ASHRAE 90.1b, CEC Listed, CSA LLC - Low Lead Compliant Certified, CSA International (Formerly AGA/CGA), NAECA Compliant, NSF 372
  • INCLUDES: 10 ft 120 VAC Power Cord, Top Temperature and Pressure Relief Valve
  • WARRANTY: 6 Years Limited Tank and Component Parts
