Bradford-White Corp Gas Water Heaters User Manual

Light Duty Through-The-Wall

Commercial Gas Water Heaters

Features:

Bradford White is ISO registered to the
9001 standard.

■ Power vented for positive exhaust during main burner operation—a

specially designed assembly blows exhaust gases directly out of the building,
eliminating the need for conventional chimneys or expensive flue systems.

■ Electronic Ignition System—pilot does not burn while water heater is in

standby mode. (115V AC required to heater)

■ 3" PVC, ABS & CPVC (76mm) vent—the water heater can be vented

horizontally or vertically with 3" (76 mm) PVC, ABS & CPVC for lengths up to 30
feet (9 m) with (3) 90° elbows. (45 equivalent feet) (13 m).

■ 4" PVC, ABS & CPVC (102mm) vent—the water heater can be vented

horizontally or vertically with 4" (102mm) PVC, ABS & CPVC for lengths up to 60
feet (18m) with (3) 90° elbows. (75 equivalent feet) (23m).

■ Vitraglas®lining—Bradford White water heater tanks are protected 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 water heater tanks.

■ Side connections—for space heating.

■ Protective magnesium rod—provides added protection against corrosion for

long trouble-free service.

■ Factory installed Hydrojet®Total Performance System—cold inlet sediment

reducing device. Helps prevent sediment build up in tank. Increases the
efficiency and delivery of hot water while minimizing temperature build up at top
of tank.

■ Factory installed dielectric waterway fittings—all heaters equipped with

special water heater nipples for longer life.

■ 2" Non-CFC foam insulation (TW3-65S-65 has 1" Non-CFC foam insulation)—

covers the sides and top of tank to save energy by retarding loss of heat. Also
increases jacket rigidity.

■ Fully automatic controls—fast acting surface-mount thermostat for automatic

temperature control. Built-in energy cut-off switch prevents abnormally high
water temperature for extra safety. Combination gas valve/electronic module
has built-in gas pressure regulation and electronic circuit controls and operates
off 24 volts.

■ NSF construction available.

■ T&P relief valve installed.

■ Brass drain valve.

■ Flue baffle—designed to maximize the amount of heat absorbed in the lower

portion of tank. Reduces air movement in the heater during standby periods to
retard heat loss up the flue.

■ Three year limited warranty on steel tank—heavy gauge steel automatically

formed, rolled and welded to assure a continuous seam for
glass lining.

■ One year limited warranty on parts.

■ Design certified by CSA International (formerly AGA and CGA).
