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 2™ Total Performance System—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—Bradford White water heater tanks are protected from the corrosive effects of hot water by an exclusive ceramic porcelain-like coating. The Bradford White high silica Vitraglas® lining provides a tough interior surface for our hot water tanks. ¦ Fully Automatic Controls—Automatic temperature selection at your fingertips. Built-in energy cut-off switch prevents abnormally high water temperature for extra safety. Built-in gas pressure regulation. ¦ Side Connections—Side tappings allow easy connection for space heating applications. ¦ Non-CFC Foam Insulation—Energy saving 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—Designed to 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—Heavy gauge steel automatically formed, rolled and welded to assure a continuous seam for glass lining. ¦ T&P Relief Valve—Installed. ¦ Brass Drain Valve. ¦ Design Certified by CSA International (formerly AGA and CGA).
