Copper Screw Type Immersion Element

(Incoloy type immersion element available upon request)

Residential Lowboy

The Lowboy Electric Models Feature:

■ DOE—All residential storage models above 20 gallon capacity meet or

exceed efficiency requirements of the Department of Energy, ASHRAE
Standard 90.1 b (current standard) and the National Appliance Energy
Conservation Act of 1987 recent amendment effective January 20, 2004
which supercedes all state and local efficiency requirements.

■ Applications—Standing at a height of less than 33", Lowboy models are ideal

for installations where space is at a premium and are perfect for tight
installations such as a closet or under a counter.

■ Fully Automatic Controls—Fast acting surface-mount thermostats for

automatic temperature control. Factory installed sensitive manual reset energy
cut-off for safety to prevent overheating.

■ Direct Heat Transfer With Immersed Elements—Transfers heat directly

and efficiently to the water. Screw-in style.

■ Factory Installed Hydrojet

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 formula that provides superior protection from the highly corrosive
effects of hot water. This formula (Vitraglas
firing at a temperature of over 1600º F.

■ 2" Non-CFC Foam Insulation—Covers the sides and top of the tank,

reducing the amount of heat loss. This results in less energy consumption,
improved operation efficiencies and jacket rigidity.

■ 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.

■ Simultaneous and Non-Simultaneous Operation Available—

Simultaneous operation indicates when both elements (if equipped) are being
heated at the same time. Non-Simultaneous operation indicates when one
element is being heated at a time.

■ Voltages Available—120V, 208V, 240V, 277V, 480V.

■ Single Phase or Three Phase Operation Available—277V may only be

wired for single phase operation.

■ T&P Relief Valve Included—Side T&P is standard. Optional top T&P

location is available.

■ Low Restriction Brass Drain Valve—Durable tamper proof design.

■ Design evaluated by ETL in accordance with Part 280.707(d) of HUD

Mobile Home Construction and Safety Standards for Energy Efficiency.
