Residential Ultra Low NOx
Energy Saver Gas Water Heater
The FVIR Eco-Defender Safety System®Models Feature:
■Defender Combustion Chamber—Incorporates the Advanced ScreenLok®
Technology Flame Arrestor and large split-door design to prevent ignition of
flammable vapors outside the water heater.
■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.
■Digital Thermal Sensor and Resettable Thermal Switch—Coordinates
with self diagnostic control to prevent water heater operation as needed.
■Millivolt Powered Control with Built-in Piezo Igniter—Easy and quick
lighting of the pilot burner by push button.
■Pedestal Base—Rugged and durable base allows easy transport and
positioning, while providing corrosion resistant contact with floor.
■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.
■No Electricity Required.
■Factory Installed Hydrojet®Total Performance System—Cold water inlet
sediment reducing device helps prevent sediment build up in tank. Increases
first hour deliveryof hot water while minimizing temperaturebuild up in tank.
■Vitraglas®Lining—BradfordWhite water heater tanks are protected from the
corrosive effects of hot water by an exclusive ceramic porcelain-like coating.
■Self Diagnostic Honeywell Gas Control—Integrated, immersion gas control
learns and monitors the combustion chamber's temperature profile and
prevents water heater operation during upset conditions. Also equipped with
an LED display to aid in start-up and diagnostics.
■1" Non-CFC Foam Insulation—Surrounds the tank surface, saving energy
by retarding loss of heat.
■Water Connections—3⁄4" NPT factory installed true dielectric fittings extend
water heater life and eases installation.
■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—Provides added protection against
corrosion for long trouble-free service.
■3x4 “Snap Lock” Draft Diverter—Allows either 3" or 4" vent connections
with inputs of 40,000 BTU/Hr. or less. Over 40,000 BTU/Hr. has the 4" “Snap
Lock” Draft Diverter.
■T&P Relief Valve—Included.
■Low Restriction Brass Drain Valve—Durable tamper proof design.
■Meets SCAQMD Rule 1121 (10ng/J NOx limit).
■Design Certified by CSA International (formerly AGA and CGA).
