Residential Power Vent Combi2TTW® Energy Saver Gas Water Heater System

Photo is of C-DW2-TW50T10FBN

The Combi2TTW® FVIR Defender Safety System® Models Feature (50T model, only):

Advanced ScreenLok® Technology Flame ArrestorDesign—Flame arrestor is designed to prevent ignition of flammable vapor outside of the water heater.

Flammable Vapor Sensor—Electronicsensor 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—Regularcleaning of air inlet openings or flame arrestor is not required under normal conditions.

Sight Window—Offersa view of the pilot and burner operation.

Pedestal Base—Ruggedand durable base allows easy transport and positioning, and provides corrosion resistant contact with floor.

All Combi2TTW® Models Feature

Heat Exchanger—Doublewall 112" O.D. glass coated (Vitraglas®) steel coil ensures separation of potable water and heating fluid.

Low Heat Exchanger Head Loss—Upto 10 GPM flow, with less than 5 ft. of head loss. Greatly reduces the required pump size for heat exchange.

Factory installed Hydrojet® 2Total PerformanceSystem—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® Lined Tank—BradfordWhite tanks are protected from the corrosive effects of hot water by an exclusive ceramicporcelain-likecoating.

Electronic Gas Control Valve—Theintegrated, immersion gas control valve offers precise temperature control for higher first hour delivery and also allows water temperature adjustment without removing the cover. Control is equipped with an LED display to aid instart-upand diagnostics.

Spark to Pilot Ignition System—Eliminatesthe constant burning pilot used on other water heaters.

Powerful Blower Motor—Ourdesign has higher torque for greater resistance to outside winds and the power to eliminate problems with difficult venting situations. This significantly quieter motor runs cooler for a considerably longer operational life.

Horizontal and Vertical Venting—With 3" or 4" PVC, ABS OR CPVC (Maximum equivalent vent length on reverse side).

Thermostatic Mixing Valve—Suppliedto help prevent injury due to scalding.

Two Protective Aluminum Anode Rods—Provide added protection against corrosion for long trouble-free service.

2" Non-CFC Foam Insulation—Surroundsthe tank surface, saving energy by retarding loss of heat.

Water Connections—3/4"NPT factory installed true dielectric fittings.

Steel Tank—Heavygauge steel automatically formed, rolled and welded.

T&P Relief Valve—Installed.

Brass Drain Valve.

Design Certified by CSA International (formerly AGA and CGA).
