Bradford White® Gas Water Heater, EF Series, 100 gal Capacity, 199999 Btu/hr, 58.6 kW-hr, 97 % Efficiency, 3 in Vent, Power Direct Vent, 15 A, 120 V, 60 Hz, NPT Connection, 150 psi, Energy Star Compliant: Yes, Liquid Propane Gas, Natural Gas Fuel, Electronic Ignition System, Direct Spark Gas Ignition, CPVC, Finish: Vitraglas® Glass, 180 deg F, 28-1/4 in Dia x 77-5/8 in H, Domestic/Import: Domestic, 10000 ft Altitude

• 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
• Protective powered anodes - each eF Series® model is provided with two 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 deg F (871 deg C)
• Direct spark ignition for improved operational dependability and durability
• Operation mode - two different digitally displayed operation mode have the capability of adjusting the temperature setting up to 180 deg F (82 deg C) and adjusting the degree setting
• 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 deg F (82 deg C), adjusting the degree setting, 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
• Pre-mix 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 10000 ft/3048 m)
• Venting versatility the eF Series® can vent vertically or horizontally with either 2 in, 3 in, 4 in or 6 in (51 mm, 7 6mm, 107 mm or 152 mm)
• 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
