Residential Ultra Low NOx High EF
Energy Saver Gas Water Heater
The High EF 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, and 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 delivery of hot water while minimizing temperature build up in tank.
■Vitraglas®Lining—Bradford White tanks are lined with a exclusively
engineered enamel formula that provides superior 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 1600ºF.
■Self Diagnostic Honeywell Gas Control—Integrated, immersion gas control
learns and monitors the combustion chamber's temperatureprofile and
prevents water heater operation during upset conditions. Also equipped with
an LED display to aid in start-up and diagnostics.
■2" Non-CFC Foam Insulation—Surrounds the tank surface, saving energy
by retarding loss of heat.
■Water Connections—3⁄4" NPT factoryinstalled 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.
■Flue Baffle—Maximizes the amount of heat absorbed by the tank and
reduces heat loss during standby periods.
■Steel Tank—Heavy gauge steel automatically formed, rolled and welded.
■T&P Relief Valve—Included.
■Low Restriction Brass Drain Valve—Durable tamper proof design.
■Meets C.E.C. Title 24, and SCAQMD Rule 1121 (10ng/J NOx limit).
■Design Certified by CSA International (formerly AGA/CGA).
