Bradford White ULG275H763N User Manual
Light Duty Commercial Ultra Low NOx
High Input Gas Water Heater
The Ultra Low NOx High Input Models Feature:
■ Bradford White ICON System
™
—Intelligent 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 tighter temperature
differentials.
-- Advanced Temperature Control System—Microprocessor constantly
monitors and controls burner operation to maintain consistent and accurate
water temperature levels.
-- Intelligent Diagnostics—An exclusive green LED light prompts the installer
during start-up and provides ten different diagnostic codes to assist in
troubleshooting.
-- Pilot On Indication—Flashing green LED provides positive indication that pilot
is on.
-- Separate Immersed Thermowell—High-strength advanced polymer
composite thermowell provides isolation between electric temperature sensor
and surrounding water. No need to drain the tank when removing gas valve.
■ 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 2
™
Total Performance System—Cold water inlet
sediment reducing device helps prevent sediment build-up in tank.
■ Vitraglas
®
Lining—Bradford White tanks are lined with an exclusively engineered
enamel formula that provides superior tank protection from the highly corrosive
effects of hot water. This formula (Vitraglas
®
) 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.
■ Side Connections—3/4" NPT tappings allow an easy connection for space
heating applications (potable water only).
■ Non-CFC Foam Insulation—Covers the sides and top of tank, reducing the
amount of heat loss. This results in less energy consumption, improved operation
efficiencies, and jacket rigidity.
■ Pedestal Base—Rugged and durable base allows easy transport and positioning,
while providing corrosion-resistant contact with floor.
■ Water Connections—Factory-installed true dielectric fittings extend water heater
life and ease installation.
■ Protective Magnesium Anode Rod—Provides added protection against
corrosion for long trouble-free service.
■ Hand Hole Cleanout—Allows inspection of tank interior and facilitates the
removal of sediment deposits (optional on 75T models).
■ 4" (107 mm) “Snap Lock” Draft Diverter
■ T&P Relief Valve—Installed.
■ Low Restriction Brass Drain Valve—Durable tamper-proof design.
■ Design Certified by CSA International (formerly AGA and CGA).
■ ULG250H553N Complies with the latest Ultra Low NOx requirement
(10 ng/J NOx limit), ULG275H763N / ULG2100H853N (14 ng/J NOx limit).
