Residential Direct Vent

Energy Saver Gas Water Heater

The Direct Vent FVIR Defender Safety System®Models Feature:

losed Combustion—All air for combustion is taken directly from the

■ C

outside. The co-axial vent pipe (pipe inside a pipe) draws combustion air in
through the outer pipe (5"), and exhausts the products of combustion through
the inner pipe (3"). The co-axial vent pipe at the top of the unit can be rotated
for venting flexibility.

■ Reinforced Seals—Seals surround the closed combustion chamber and the

FVIR inner door, preventing the ignition of flammable vapors outside of the
water heater.

■ Piezo Igniter—Easy and quick lighting of the pilot bur

■ Pedestal Base—Rugged and durable base allows easy transport and

positioning, corrosion resistant contact with floor.

■ Maintenance Free—The co-axial vent piping and the closed combustion

chamber with reinforced seals do not require regular cleaning under normal
operating conditions.

■ Sight Window—Offers a view into the combustion chamber to observe the

operation of the pilot and burner.

■ No Electrical Power Necessary.

■ Factory installed Hydrojet

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—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
for our water heater tanks.

■ Fully Automatic Controls—Built-in gas pressure regulation and energy cut-

off switch.

■ Optional Vent Kits—Allow for up to 8 foot max vertical and 8 foot max

horizontal (2.4 meters). All DS models must be terminated horizontally.

■ 1" Non-CFC Foam Insulation—Surrounds the 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.

■ Factory Installed Heat T

reduces heat loss in piping and eliminates the potential for noise generation.

■ Protective Magnesium Anode Rod—Provides added protection against

corrosion for long trouble-free service.

■ Flue Baffle—Maximizes the amount of heat absorbed by the tank and

educes heat loss during standby periods.
