FEATURING:
The FVIR Eco-Defender Safety System® Models Feature:
■ 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 Venting System—Power Direct Vent closed combustion system
utilizes external air for combustion and exhausts directly to the outside through a separate
two-pipe system. The equivalent feet of intake venting cannot be greater than the
equivalent feet of exhaust venting.
■ 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 standby
periods (120 VAC).
-- Enhanced Performance—Proprietary algorithms provide enhanced First Hour Rating and
tighter temperature differential.
-- 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.
■ Cast Aluminum Air Intake Boot—A cast molded air intake boot design provides
exceptional durability during installation and operation.
■ Flammable Vapor Sensor—Electronic sensor prevents burner operation if flammable
vapors are detected. The sensor will also prevent operation if there is ongoing flammable
vapors burning inside the combustion chamber.
■ Factory-Installed Hydrojet® Total Performance System—Sediment reducing device
that also increases first hour rating 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°F (871°C).
■ Optional Concentric Vent Kit Termination—Concentric termination fitting provides for
only one exit opening through a wall or roof. (Subtract 10ft. (3m) for intake pipe and 10ft.
(3m) for exhaust pipe when calculating total vent length.)
■ Horizontal and Vertical Venting—PVC, ABS, or CPVC (Maximum equivalent vent length
for each pipe on reverse side).
■ Insulation System—2" (51mm) Non-CFC foam insulation covers the sides and top of the
tank, reducing heat loss. This results in less energy consumption, improved efficiencies,
and jacket rigidity.
■ Water Connections—3⁄4" (19mm) NPT factory-installed true dielectric fittings.
■ Side Connections—3⁄4" (19mm) NPT tappings allow easy connections for space heating
applications (Potable water only).
■ 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.
■ T&P Relief Valve—Installed.
■ Low Restrictive Brass Drain Valve—Durable tamper proof design.
■ Complies with the latest Ultra Low NOx requirement (10 ng/J NOx limit).
