The Direct Vent FVIR Defender Safety System
®
Models Feature:
■ C
losed Combustion—
A
ll air for combustion is taken directly from the
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
ner by push button.
■ 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
®
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—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.
■ 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
raps—
Design incorporates a flexible disk that
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
r
educes heat loss during standby periods.
■ Steel T
ank—
Heavy gauge steel automatically for
med, r
olled and welded.
■ T&P Relief Valve—Included.
■ Brass Drain Valve.
