Bradford White Combi2 C-DW2-504T10FBN User manual

Residential Atmospheric Vent Combi2™
Energy Saver Gas Water Heater System
The Combi2™FVIR Defender Safety System®Models Feature
(504T model only):
■Advanced ScreenLok®Technology Flame Arrestor Design—Flame
arrestor is designed to prevent ignition of flammable vapor outside of the
water heater.
■Resettable Thermal Switch—Proven and 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—Rugged and durable base allows easy transport and
positioning, and provides corrosion resistant contact with floor.
■Maintenance Free—Regular cleaning of air inlet openings or flame arrestor
is not required under normal conditions.
■Sight Window—Offers a view into the combustion chamber to observe the
operation of the pilot and burner.
■Piezo Igniter—Easy and quick lighting of the pilot burner by push button.
All Combi2™Models Feature:
■Heat Exchanger—Double wall 11⁄2"O.D. glass coated (Vitraglas®)steel coil
ensures separation of potable water and heating fluid.
■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.
■Factory Installed Hydrojet®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 in tank.
■Vitraglas®lining—BradfordWhite water heater tanks areprotected from the
corrosive effects of hot water by an exclusive ceramic porcelain-like
coating. The Bradford White high silica Vitraglas®lining provides a tough
interior surface for our hot water tanks.
■Fully Automatic Controls—Built-in energy cut-off switch prevents
abnormally high water temperature for extra safety. Built-in gas pressure
regulation.
■Thermostatic Mixing Valve—Supplied with unit to help prevent injury due
to scalding.
■2" Non-CFC Foam Insulation—Surrounds the tank surface, saving energy
by retarding loss of heat.
■Water Connections—3/4" NPT factoryinstalled 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—Heavy gauge steel automatically formed, rolled and welded.
■Stainless Steel Flue Baffle—Maximizes the 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).
