BRADFORD WHITE Commercial eF Series Ultra High Efficiency Gas Water
Heater
Instruction
The eF Series® Models feature:
-
ENERGY STAR® Models Available—EF60T125 & EF100T (150,199,250) Models.
-
Thermal Efficiency up to 97%—Ultra High Efficiency results in less fuel consumption and greater hot water recovery.
-
BMS Integration—Via Modbus standard, BACnet® compatible via gateway kit.*
-
ICON HD®—Intelligent proven design combines temperature control, diagnostic codes, and system ignition functions into a single control board with a digital LCD display. n Protective Powered Anodes—Each eF Series® model is provided with 2 powered anode rods.
-
Factory Installed Hydrojet® Sediment Reduction System—Cold water inlet sediment reducing device helps prevent sediment build up in the tank.
-
Vitraglas® Lining—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). -
Direct Spark Ignition—For improved operational dependability and durability.
-
Operation Mode—Two different digitally displayed operation modes have the capability of adjusting the temperature setting up to 180°F (82°C), and adjusting the degree setting (ºF to ºC, or ºC to ºF).
-
Service Mode—Eight different digitally displayed service screens can be easily cycled through by pressing the select button. There is the capability of adjusting the temperature setting up to 180°F (82°C), adjusting the degree setting (ºF to ºC, or ºC to ºF), locking the maximum temperature setting that can be adjusted in operation mode, displaying the temperature sensor reading, displaying the flame current, and displaying diagnostic codes.
-
Premix Power Burner—A self compensating negative regulation system automatically increases or decreases fuel flow when a change in combustion air is detected. This provides the range for optimum combustion and efficiency (automatic high altitude compatibility up to 10,000 ft./3,048m).
-
Venting Versatility—The eF Series® can vent vertically or horizontally with either 2″, 3″, 4″ or 6″ (51mm, 76mm, 107mm or 152mm) PVC, CPVC, Polypropylene, Stainless Steel, or ABS (not approved for Canada) vent pipe, and is approved for direct vent closed combustion applications, or those applications that require inside air for combustion. The eF Series® is also approved for unbalanced venting, which means the air intake pipe doesn’t have to be vented the same distance as the exhaust.
-
Three Pass Fire Tube Heat Exchanger System—The three pass Heat Exchanger
system keeps the hot combustion gases moving at a high velocity. The combination of high turbulence and velocity causes an enormous rate of heat transfer into the water. n Ultra Quiet Operation. -
A Single Exhaust Pressure Switch.
-
1″ (25mm) NPT Side Connections for Space Heating.
-
Sanitizing Capability—Temperature setting up to 180°F (82°C).
-
Complies with the latest ultra-low NOx requirement (14 ng/J NOx limit for natural gas and 77ppm NOx limit for liquid propane).
-
ASME Code Available on All Models.
-
NSF Construction Available.
-
T&P Relief Valve—Installed.
-
Low Restrictive Brass Drain Valve—Durable tamper proof design.
-
Not available on certain dash number variations.
3 or 5-Year Limited Tank Warranties / 1-Year Limited Warranty on Component Parts.
For more information on warranty, please visit www.bradfordwhite.com
For products installed in USA, Canada, and Puerto Rico. Some states do not allow limitations on warranties. See complete copy of the warranty included with the heater.
eF Series® Additional Equipment Features
- Submerged Combustion Chamber—Submerging the combustion chamber in the center of the water storage tank minimizes radiant heat loss and improves efficiency.
- Zero Inch Clearance—The eFSeries® jacket is cool to the touch and is approved for zero inch clearance to combustibles for unsurpassed installation flexibility.
- Water Connections—Factory-installed true dielectric fittings extend water heater life and simplify water line connections.
- Hand Hole Cleanout—Allows inspection of tank interior and facilitates the removal of sediment deposits.
- E.C.O.—A manual re-set Energy Cut Off (E.C.O) shuts off all gas in event of an overheat condition. The ECO is manually resettable.
- 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.

Commercial Gas High Efficiency Water Heater
Sample Specification
The water heater shall be a Bradford White model EF- 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, and 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. The tank shall have four extruded magnesium anode rods installed in
separate head couplings. 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
electronic ignition system, an ASME rated T&P relief valve and a premix closed
combustion system for direct venting using either 2″, 3″, 4″ or 6″ (51mm,
76mm, 107mm or 152mm) PVC, CPVC, Polypropylene, Stainless Steel, or ABS vent
pipe. The water heater shall be factory assembled and tested. The water heater
shall be approved for zero inch clearance to combustibles. 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), 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 (115V AC required), or elaborate
piping network. When equipped with a mixing valve, it will 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.
