Photo is of C-DW2-504T10FBN

The Combi2FVIR Defender Safety System® Models Feature (504T model only):

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

Resettable Thermal Switch—Provenand reliable bimetallic switch prevents burner and pilot operation in case of ongoing flammable vapor burn inside of the combustion chamber or restricted air flow.

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

Maintenance Free—Regularcleaning of air inlet openings or flame arrestor is not required under normal conditions.

Sight Window—Offersa view into the combustion chamber to observe the operation of the pilot and burner.

Piezo Igniter—Easyand quick lighting of the pilot burner by push button.

All Combi2Models 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® Total PerformanceSystem—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—BradfordWhite water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramicporcelain-likecoating. The Bradford White high silica Vitraglas® lining provides a tough interior surface for our hot water tanks.

Fully Automatic Controls—Built-inenergycut-offswitch prevents abnormally high water temperature for extra safety.Built-ingas pressure regulation.

Thermostatic Mixing Valve—Suppliedwith unit to help prevent injury due to scalding.

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 extend water heater life and eases installation.

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

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

Stainless Steel Flue Baffle—Maximizesthe amount of heat absorbed by the tank and reduces heat loss during standby periods.

T&P Relief Valve—Installed.

Brass Drain Valve.

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