Bradford White C-DW2-TW50T10FBN, C-DW2-TW75T10BN User Manual
Residential Power Vent Combi2™TTW
®
Gas Water Heater System
The Combi2™TTW®FVIR Defender Safety System®Models Feature
(50T model, only):
■ Advanced ScreenLok
®
Technology Flame Arrestor Design—Flame arrestor
is designed to prevent ignition of flammable vapor outside of the water heater.
■ Flammable Vapor Sensor—Electronic sensor prevents burner operation if
flammable vapors are detected. The sensor will also prevent operation if there
is ongoing flammable vapor burn inside the combustion chamber.
■ Maintenance Free—Regular cleaning of air inlet openings or flame arrestor is
not required under normal conditions.
■ Sight Window—Offers a view of the pilot and burner operation.
All Combi2™ TTW®Models Feature
■ Internal Double Wall Heat Exchanger—11⁄2" O.D. glass coated (Vitraglas®) steel
coil ensures separation of potable water and heating fluid.
-- 3/4" NPT Solar Collector Supply and Return Connections.
■ Low Heat Exchanger Head Loss—Up to 8 GPM flow, with less than 6 ft. of
head loss. Greatly reduces the required pump size for heat exchange.
■ Honeywell Self Diagnostic Electronic Gas Control—Intelligent gas control with
spark to pilot ignition system that eliminates the constant burning pilot. This results
in savings of pilot gas during stand-by periods (120 V.A.C.).
-- 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 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.
■ Factory installed Hydrojet
®2™
Total Performance System—Cold water inlet
sediment reducing device helps prevent sediment build up in tank. Increases
first hour delivery and 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).
■ Horizontal and Vertical Venting—With 3" or 4" PVC, ABS OR CPVC
(Maximum equivalent vent lengths on reverse side).
■ 2" 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.
■ Two Protective Anode Rods.
■ T&P Relief Valve—Installed.
■ Low Restriction Brass Drain Valve—Durable tamper proof design.
■ Thermostatic Mixing Valve (ASSE Approved)—Included.
