ULG275H763N
FEATURING:
The Ultra Low NOx High Input Models Feature:
■ Bradford White ICON System
®
—ntelligent gas control with proven millivolt
powered technology and built-in piezo igniter. A standard, off the shelf thermopile
converts heat energy from the pilot flame into electrical energy to operate the gas
valve and microprocessor. No need for external electricity.
-- Enhanced Performance—Proprietary algorithms provide enhanced First Hour
Rating and tighter temperature differential.
-- Advanced Temperature Control System—Microprocessor constantly monitors
and controls burner operation to maintain consistent and accurate water
temperature levels.
-- Intelligent Diagnostics—Exclusive multicolor LED light indicates operation
status/service required.
■ Ultra Low NOx Burner with Primary and Secondary Air Distribution
Devices—Ensures proper air to gas ratio for reduction of NOx generated by the
combustion process.
■ Maintenance-Free—No regular cleaning of air inlet openings or flame arrestor is
required under normal conditions (ULG250H553N only).
■ Sight Window—Offers a view into the combustion chamber to observe the
operation of the pilot and burner.
■ Factory-Installed Hydrojet
®
Total Performance System—Sediment reducing
device that also increases first hour rating of hot water while minimizing temperature
build-up in tank.
■ Vitraglas
superior tank protection from the highly corrosive effects of hot water. This formula
(Vitraglas
®
Lining—An exclusively engineered enamel formula that provides
®
) is fused to the steel surface by firing at a temperature of over 1600°F
(871°C).
■ More Precise Temperature Control—With an adjustable temperature up to 180°F
(82°C).
■ Side Connections—3/4" (19mm) NPT tappings allow an easy connection for
space heating applications (potable water only).
■ Insulation System—Non-CFC foam covers the sides and top of the tank, reducing
heat loss. This results in less energy consumption, improved efficiencies, and jacket
rigidity.
■ Pedestal Base—Rugged and durable base allows easy transport and positioning,
while providing corrosion-resistant contact with floor.
■ Water Connections—3⁄4" (19mm) NPT factory-installed true dielectric fittings
extend water heater life and simplify water line connections.
■ Protective Magnesium Anode Rod—Provides added protection against
corrosion for long-term, trouble-free service.
■ Hand Hole Cleanout—Allows inspection of tank interior and facilitates the removal
of sediment deposits (ULG2100H803N models only).
■ 4" (107 mm) “Snap Lock” Draft Diverter
■ T&P Relief Valve—Installed.
■ Low Restrictive Brass Drain Valve—Durable tamper proof design.
■ Design Certified by CSA International (formerly AGA/CGA).
■ ULG250H553N Complies with the latest Ultra Low NOx requirement
(10 ng/J NOx limit), ULG275H763N / ULG2100H803N (14 ng/J NOx limit).
