Features N/A The Direct Vent FVIR Eco-Defender Safety System® Models Feature:
  • Ultra Low NOx Burner with Primary and Secondary Air Distribution Devices - Ensures proper air to gas ratio for reduction of NOx generated by the combustion process.
  • Self Diagnostic Honeywell Gas Control - Integrated, immersion gas control learns and monitors the combustion chamber's temperature profile and prevents water heater operation during upset conditions. Also equipped with an LED display to aid in start-up and diagnostics.
  • 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 (6"), and exhausts the products of combustion through the inner pipe (4"). 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.
  • Maintenance Free - The vent piping and the closed combustion chamber with reinforced seals does 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.
  • 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 tanks are lined with an exclusively engineered enamel formula that provides superior tank protection from the highly corrosive effects of hot water. This formula (Vitraglas®) is fused to the steel surface by firing at a temperature of over 1600 ºF (871 ºC).
  • Cast Aluminum Air Intake Boot - A cast molded air intake boot provides exceptional installation durability.
  • Telescoping Solid Vent Kits - Multiple kits (see reverse side) allow up to 8 ft. vertical and 8 ft. horizontal vent lengths (horizontal termination only).
  • Flexible Vent Kit - The maximum vent length (horizontal and vertical) can be flexed to 100" (horizontal termination only).
  • Side Connections - 3/4" NPT tappings allow easy connections for space heating applications (Potable water only).
  • 1" Non-CFC Foam Insulation - Covers the sides and top of tank, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies and jacket rigidity.
  • Pedestal Base.
  • Water Connections - 3/4" NPT factory installed true dielectric fittings.
  • Factory Installed Heat Traps.
  • Protective Magnesium Anode Rod.
  • T & P Relief Valve - Included.
  • Low Restriction Brass Drain Valve - Durable tamper proof design.
  • Complies with the latest ultra-low NOx requirement (10 ng/J NOx limit).

General Information N/A All gas water heaters are certified at 300 psi test pressure (2068 kPa) and 150 psi working pressure (1034 kPa). All potable water connections are 3/4" NPT (19 mm) on 11" (203 mm) centers. All gas connections 1/2" (13 mm).
All models design certified by CSA® International (formerly AGA/CGA), ANSI Z-21.10.1 and peak performance rated.
Dimensions and specifications subject to change without notice in accordance with our policy of continuous product improvement. Suitable for Water (Potable) Heating and Space Heating.
Toxic chemicals, such as those used for boiler treatment, shall NEVER be introduced into this system. This unit may NEVER be connected to any existing heating system or component(s) previously used with a non-potable water heating appliance.
Note N/A Telescoping Solid Vent Kit (239-47811-00) or Flexible Vent Kit (239-47813-00) can be ordered and shipped with water heater, or ordered and shipped separately.

Meet or exceed ASHRAE 90.1b (Current standard) C.E.C. Listed 78% Recovery Efficiency.
