General Information
All electric water heaters are certified at 300 psi test pressure (2068 kPa) and 150 psi working pressure (1034 kPa). All models are design certified by ETL, for up to 180 ºF (82 ºC) application as an Automatic Storage Heater, and an Automatic Circulating Tank 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 will 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).
Dimensions and specifications subject to change without notice in accordance with our policy of continuous product improvement.



Features
The Immersion and Surface Mounted Electric Models Feature:
  • Surface Mounted Thermostat Step Control (modulation) - Can be accomplished by variable setting on thermostats (each element has an individual thermostat and high limit).
  • Immersion Thermostats - Immersion type for accurate temperature control from up to 180 ºF (82 ºC) with manual reset high limit control.
  • 3" (76 mm) 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.
  • 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. This formula (Vitraglas®) is fused to the steel surface by firing at a temperature of over 1600 ºF (871 ºC).
  • Water Connections - 1 1/2" NPT factory installed true dielectric fittings extend water heater life and eases installation.
  • Elements - Screw in style. Surface mounted thermostat models have elements made of nickel chromium wire embedded in magnesium oxide, sheathed in copper and electroplated to minimize degradation of the anode. Incoloy sheathed elements are optional (Incoloy elements are standard for all 600 volt models). Immersion thermostat models have low watt density incoloy sheathed elements standard which resists burnout caused by dry fire or lime buildup.
  • Two Magnesium Anode Rods - Provide added protection against corrosion for long trouble free service.
  • Hand Hole Cleanout - Allows inspection of tank interior and facilitates the removal of sediment deposits.
  • ASME Construction Available.
  • NSF Construction Available.
  • Low Restriction Brass Drain Valve - Durable tamper proof design.
  • T&P Relief Valve - Installed.
  • Completely Pre-wired - With pressure lug terminal block eliminating need for splicing or taping of wires.
  • Voltages Available - 208 V, 240 V, 277 V, 380 V, 415 V, 480 V and 600 V.




Warranty
  • 3-Year Limited Warranty - On Inner Glass-Lined Tank.
  • 1-Year Limited Warranty - On all Other Component Parts.




Note
Units with amperage draw of 48 amps or more require factory installed internal fusing.

Optional surface thermostats ranging from 80 ºF to 140 ºF are available.

Meet or exceed ASHRAE 90.1b (current standard) C.E.C. Listed.
