General Information
All gas water heaters are certified at 300 psi test pressure (2068 kPa) and 150 psi working pressure (1034 kPa). All models are design certified by CSA® International (formerly AGA/CGA), to ANSI standard Z-21.10.3, for up to 180 ºF (82 ºC) application as an Automatic Storage Heater. As an Automatic Storage Heater, all models are complete, self-contained water heating systems. It needs no separate storage tank, pump, wiring or elaborate piping network. When equipped with a mixing valve, it can supply 180 ºF (82 ºC) sanitizing and lower temperature general purpose hot water simultaneously. These models can be used either as a single unit or in multiples connected in series or parallel (recommended).



Features
The Ultra-Low NOx Models feature:
  • ICON HD™ - The proven design of an intelligent Honeywell® Integrated Control combines temperature control, diagnostic codes, and system functions and status into a single control with a digital LCD display.
    • Operation Mode - Simple, intuitive temperature adjustment up to 180 ºF/82 ºC. The user can easily select between Fahrenheit and Celsius.
    • Service Mode - The display has a "Service Mode" for changing the maximum setpoint and accessing information that may aid in the service of the water heater. These eight digitally displayed service screens can be easily cycled through by pressing the select button. The service screens include: max setpoint value, water temperature reading, flame current of pilot flame sensor, current temperature setpoint, ºF/ºC display change, temperature differential, software version, and error code history (up to ten previous error codes).
  • Premix Power Burner - A self compensating negative pressure system automatically regulates fuel flow when a change in combustion air is detected. This provides for optimum combustion and efficiency.
    Automatically adjusts for altitudes up to 10,000 ft.
  • Direct Spark Ignition - For improved operational dependability and durability.
  • Factory Installed Recirculation System - Designed to reduce thermal stratification throughout the tank.
  • Integrated Exhaust System - New configuration and vent connector height allow for easy replacement of existing atmospheric vent water heaters.
  • Sanitizing Capability - Complies with sanitation capabilities up to 180 ºF (82 ºC).
  • Factory Installed Hydrojet® Sediment Reduction System - Cold water inlet sediment reducing device helps prevent sediment build up in the 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. Vitraglas® is fused to the steel surface by firing at a temperature of over 1600ºF (871ºC).
  • Non-CFC Foam Insulation - Covers the sides of tank, reducing the amount of heat loss. This results in less energy consumption, improved operation efficiencies and jacket rigidity.
  • Water Connections - Factory installed true dielectric waterway fittings extend water heater life and eases installation.
  • Horizontally Configured Magnesium Anode Rods - Can easily be serviced from the side of the water heater (65 gallon has 3 anodes; 100 gallon has 5 anodes).
  • 14 Models Available - 65-100 gallon capacities, 155,000-399,999 BTU/Hr.
  • 84% Thermal Efficiency.
  • Zero Inch Clearance to Combustibles.
  • Hand Hole Cleanout.
  • NSF Construction Available.
  • T & P Relief Valve - Installed.
  • Low Restriction Brass Drain Valve - Durable tamper proof design.
  • Ultra-Low NOx Construction Standard (14 ng/J NOx emissions).
  • CSA Certified Low Lead Content.




Warranty
  • 5-Year Limited Tank Warranty / 1-Year Limited Warranty on Component Parts.
