Commercial Gas Light Duty
High Input Direct Vent Water Heater
Features:
Bradford White is ISO registered to the
9001 standard.
■ 1" Non-CFC foam insulation—surrounds the tank surface, saving
energy by retarding loss of heat.
■ Closed combustion—all air for combustion is taken directly from the
outside. The co-axial vent pipe (pipe inside a pipe) draws combustion
air in through the outer pipe (6"), and exhausts the products of
combustion through the inner pipe (4").
■ Co-axial—rotational venting at top of unit.
■ No electrical power necessary.
■ Piezo igniter—for ease of lighting the pilot.
■ Water Connections—3/4" NPT factory installed true dielectric fittings.
Extends water heater life and eases installation.
■ Vitraglas®lined tank—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 water heater tanks.
■ Factory installed Hydrojet®Total Performance System—cold inlet
sediment reducing device. Helps prevent sediment build up in tank.
Increases first hour delivery of hot water while minimizing temperature
build up at top of tank.
■ Protective magnesium anode rod—provides added protection
against corrosion for long trouble-free service.
■ Brass drain valve.
■ T&P relief valve—factory installed.
■ Side Tappings—for space heating purposes.
■ 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. Fastacting thermostat starts heat recovery cycle sooner.
■ NSF construction available.
■ Optional vent kits—allow for up to 8 foot max vertical and 8 foot max
horizontal (2.4 meters)). All DH models must be terminated horizontally.
■ Three year limited warranty on steel tank—heavy gauge steel
automatically formed, rolled and welded to assure a continuous seam
for glass lining.
■ One year limited warranty on parts.
■ Design certified by CSA International. (formerly AGA and CGA)
