Residential Power Vent Combi1™ TTW® Energy Saver Gas Water Heater System Photo is of C-SW2-TW50T10FBN FEATURING: The Combi1™ 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 Combi1™ TTW® Models Feature ■ Internal Single Wall Heat Exchanger—11⁄2" O.D. glass coated (Vitraglas®) steel coil. -- 1" NPT Solar Collector Supply and Return Connections. ■ Low Heat Exchanger Head Loss—Up to 10 GPM flow, with less than 5 ft. of head loss. Greatly reduces the required pump size for heat exchange. ■ Integrated Mixing Device—Features an accurate, easy to use hand wheel for adjusting mixed water temperature, a pre-piped stainless steel flexible connector for quick installation as well as optional water connections (1/2" NPT recirculation inlet, 1/2" NPT hot water outlet, 1/4" NPT cold water outlet). This required system is easily installed and ensures a comfortable outlet temperature while providing a steady flow of hot water. ■ Honeywell Self Diagnostic Electronic Gas Control —Intelligent gas control with spark to pilot ignition system 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. 10-Year Limited Tank and Heat Exchanger Warranties / 6-Year Limited Warranty on Component Parts.
