Up to 82% Thermal Efficiency
For Propane Gas models change suffix “N” to “X”. Example: UCG-100H-199-3X (UCG-100H-399 available in Natural Gas only). All models comply with the
latest Ultra Low NOx requirements (14 ng/J or less for natural gas and 77 ppm NOx limit for liquid propane).
Amp Draw range = 1.0 to 1.8 amps.
(A) ASME - All models are available with ASME construction.
To order ASME construction add the (A) to the end of the model number.
* Based on manufacturer’s rated recovery efficiency.

Sample Specification
The water heater shall be a Bradford White model UCG-_____ with a rated storage capacity of not less than _____ gallons/ liters, a minimum gas input of __________ BTU/Hr., a minimum
recovery of _____ GPH/LPH at 100°F (56°C) temperature rise, a Thermal Efficiency Rating of _____. It shall be design certified by CSA International (formerly AGA and CGA) for 180°F (82°C)
application, either with or without a separate storage tank. The tank shall be lined with Vitraglas
®
vitreous enamel and shall have a bolted hand hole cleanout. This water heater shall be
equipped with stainless steel cold water inlet, Hydrojet
®
Sediment Reduction System. The heater shall be insulated with Non-CFC foam. This water heater shall be equipped with an ICON
HD
®
ignition system, an ASME rated T&P relief valve and a premix combustion system. The water heater shall be factory assembled and tested. A digital LCD display shall be integrated into
the front and be an adjustable electronic thermostat to any temperature up to 180°F. A recycling Energy Cut Off (E.C.O.) shuts off all gas in the event of an overheat condition. The entire
installation shall be made in compliance with state and local codes and ordinances.
General
All gas water heaters are certified at 300 PSI test pressure (2068 kPa) and 150 PSI working pressure (1034 kPa). All models are design certified by CSA International (formerly AGA/CGA), to
ANSI standard Z-21.10.3, for up to 180°F (82°C) application as an Automatic Storage Heater. As an Automatic Storage Heater, all models are complete, self-contained water heating systems.
It needs no separate storage tank, pump, wiring or elaborate piping network. When equipped with a mixing valve, it can supply 180°F (82°C) sanitizing and lower temperature general purpose
hot water simultaneously. These models can be used either as a single unit or in multiples connected in series or parallel (recommended).
Dimensions and specifications subject to change without notice in accordance with our policy of continuous product improvement.
