The Direct Vent FVIR Defender Safety System®Models Feature:

Bradford White is ISO registered to the 9001-2008 standard.

■ 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 (5"), and exhausts the products of combustion through the inner pipe
(3"). The 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 do 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 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°F (871°C).

■ Cast Aluminum Air Intake Boot—A cast molded air intake boot provides

exceptional installation durability.

■ Telescoping Solid Vent Kits—Multiple kits (see reverse side) allow up to 8ft.

vertical and 8ft. horizontal vent lengths (horizontal termination only).

■ Flexible Vent Kit—The maximum vent length (horizontal and vertical) can be

flexed to 100" (horizontal termination 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.

■ Low Restriction Brass Drain Valve—Durable tamper proof design.

■ Suitable for residential and light duty commercial applications.
