Bradford White Combi2 TTW C-DW2-TW50T10FBN User manual

Residential Power Vent Combi2™TTW®
Energy Saver Gas Water Heater System
The Combi2™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.
■Pedestal Base—Rugged and durable base allows easy transport and
positioning, and provides corrosion resistant contact with floor.
All Combi2™TTW®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.
■Factoryinstalled 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®Lined Tank—BradfordWhite tanks are protected from the
corrosive effects of hot water by an exclusive ceramic porcelain-like coating.
■Electronic Gas Control Valve—The integrated, 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 in start-up and diagnostics.
■Spark to Pilot Ignition System—Eliminates the constant burning pilot used
on other water heaters.
■Powerful Blower Motor—Our design 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—Supplied to 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—Surrounds the tank surface, saving energy
by retarding loss of heat.
■Water Connections—3/4" NPT factoryinstalled true dielectric fittings.
■Steel Tank—Heavy gauge steel automatically formed, rolled and welded.
■T&P Relief Valve—Installed.
■Brass Drain Valve.
■Design Certified by CSA International (formerly AGA and CGA).
