Features

N/A
The TTW® 4 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.
- Flammable Vapor Sensor and Resettable Thermal Switch - Coordinates with control to prevent 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 - 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.
All TTW® 2 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.
- 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 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 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.
- 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.
- Compatible with Optional Accessory Packages - Performance Package, Protection Package and Inlet Shut-off Valve.
- Powerful Blower Motor - Our significantly quiet design has greater resistance to outside winds and the power to vent in many difficult venting situations.
- Horizontal and Vertical Venting - With 3" or 4" PVC, ABS or CPVC (Maximum equivalent vent length on reverse side).
- Factory Installed Hydrojet®2™ 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 at top of 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 ºF (871 ºC).
- 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.
- Water Connections - 3/4" NPT factory installed true dielectric fittings.
- 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.
- 3/4" NPT Side Connections.
- Pedestal Base.
- T&P Relief Valve - Included.
- Low Restriction Brass Drain Valve - Durable tamper proof design.
- Complies with the latest ultra-low NOx requirement (10 ng/J NOx limit).
