The Direct Vent FVIR Defender Safety System® Models Feature:

• Closed Combustion--All 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 burner by push button. n 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 cutoff 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 Traps--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 reduces heat loss during standby periods.
• Steel Tank--Heavy gauge steel automatically formed, rolled and welded.
• T&P Relief Valve--Included.
• Brass Drain Valve.
• Design Certified by CSA International (formerly AGA and CGA).
