"Highest in Subcontractor Satisfaction among Water Heater/Boiler Manufacturers"

Light Duty Commercial High Performance

Energy Saver Gas Water Heater

The LD Atmospheric Vent High Performance Series Models feature:

High Input Combustion System—Generatesenough hot water in the first hour for mop sinks, wash tubs and large wash sinks in addition to standard commercial duty.

OptimizerTemperature ControlSystem—Integrated mixing device features a thermostatically controlled mixing device that is pre-piped with a flexible connector. This required system is easily installed and designed for each specific water heater. The mixing device ensures a comfortable outlet temperature while providing a steady flow of hot water.

Alternate Temperature Water Outlet Kit—3/4" NPT connections provide up to 180° F on hot water outlet side for high temperature applications. Not recommended for 180°F sanitizing.

Factory Installed Hydrojet 2Total PerformanceSystem—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—BradfordWhite water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramicporcelain-likecoating. The Bradford White high silica Vitraglas® lining provides a tough interior surface for our hot water tanks.

Fully Automatic Controls—Automatictemperature selection at your fingertips.Built-inenergycut-offswitch prevents abnormally high water temperature for extra safety.Built-ingas pressure regulation.

Side Connections—Sidetappings allow easy connection for space heating applications.

Non-CFC Foam Insulation—Energysaving insulation covers the sides and top of the tank, reducing the amount of heat loss while increasing jacket rigidity. 25X has 2" of insulation, 55X has 1" of insulation.

Water Connections—3⁄4"NPT factory installed true dielectric fittings extend water heater life and eases installation.

Two Protective Magnesium Anode Rods—Provide added protection against corrosion for long trouble-free service.

“Snap Lock” Draft Diverter.

Helical Fin Flue—Designedto maximize the amount of heat transferred to water decreasing recovery time. Minimizes air movement in the heater during standby periods to retard heat loss up the flue.

Steel Tank—Heavygauge steel automatically formed, rolled and welded to assure a continuous seam for glass lining.

T&P Relief Valve—Installed.

Brass Drain Valve.
