ASME Code Tank Construction - Standard.
Immersion Thermostats - Immersion type for accurate temperature control from up to 180 ºF (82 ºC) with manual reset high limit control.
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" (38 mm) NPT factory installed true dielectric fittings extend water heater life and eases installation.
Elements - Screw in style. Low watt density incoloy material helps to minimize dry fire and prevents lime build up.
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.
Protective Magnesium Anode Rod - Provides added protection against corrosion for long trouble-free service.
Completely Pre-wired - With pressure lug terminal block eliminating need for splicing or taping of wires.
Hand Hole Cleanout - (20 thru 120 gallon models only).
T&P Relief Valve - Installed.
Low Restriction Brass Drain Valve - Durable tamper proof design.
NSF Construction Available on All Models.
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.
High and Low Water Pressure Controls - The Controls interrupt the electrical current to the contactor coil when the pressure settings are exceeded.
Low Water Level Control - This Control will interrupt the electrical current to the contactor coil when a low water level condition is sensed inside the water heater tank. When the low water level condition is corrected the control will automatically sense the new situation and electrical current will again energize the contactor coil. Normal water heater operation will be resumed.
Alarm Horn - The Alarm Horn is an option specified when the installation desires an audible signal to immediately sound an alert when the water heater operation is interrupted for certain faults. Referring to the control circuit wiring diagram, the alarm will activate when any one of the following events occur:
The Hi-Limit control has been tripped
The High Water Pressure Control senses excessive pressure
The Low Water Pressure Control senses insufficient pressure
The Low Water Level Control senses an insufficient quantity of water
Heating Element Sequencers - Heating element sequencers are available in order to stage the activation of the heating elements thereby, reducing the inrush current to the water heater. The sequencers will control one or two contactor coils depending upon the water heater voltage, phase, and kW.
Electrical Door Lock - An electrical door lock is offered in order to secure the access to the water heater control cabinet. This device will lock the control cabinet door when the 120 V AC control circuit voltage is applied to it.
Low Temperature Surface Mount Thermostats - Adjustable from 80 ºF - 140 ºF.
Temperature and Pressure Gauge - Displays approximate temperature of the water and approximate pressure inside the tank.
3-Year Limited Tank Warranty / 1-Year Limited Warranty on Component Parts.
Meet or exceed ASHRAE 90.1b (Current standard) C.E.C. Listed.
Units with amperage draw of 48 amps or more require factory installed internal fusing.
