Bradford White 25X-78B-3N User manual

Light Duty Commercial High Performance
Energy Saver Gas Water Heater
The LD Atmospheric Vent High Performance Series Models feature:
■High Input Combustion System—Generates enough hot water in the first
hour for mop sinks, wash tubs and large wash sinks in addition to standard
commercial duty.
■Optimizer™Temperature Control System—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 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 temperatureselection 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).
