The Direct Vent FVIR Eco-Defender Safety System
®
Models Feature:
■ 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.
■ Ultra Low NOx Burner with Primary and Secondary Air Distribution Devices—Ensures proper
air to gas ratio for reduction of NOx generated by the combustion process.
■ 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 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).
■ Side Connections—3/4" NPT tappings allow easy connections for space heating applications
(Potable water only).
■ 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.
■ Factory Installed Heat Traps.
■ Protective Magnesium Anode Rod.
■ T&P Relief Valve—Included.
■ Low Restriction Brass Drain Valve—Durable tamper proof design.
■ Design Certified by CSA International (formerly AGA and CGA).
■ Complies with the latest ultra-low NOx requirement (10 ng/J NOx limit).
