• Minimum gas supply pressure - 4" w.c.
• Maximum gas supply pressure - 13" w.c.
• 85+% AFUE
• Sealed stainless steel combustion chamber
• Hot surface ignition
• Automatic burner modulation from 57% to full fire
• NOx levels less than 25 ppm
• Venting - Direct vent (sealed combustion with ducted combustion air in concentric vent) or Category III
• Design certified for installation directly on a combustible floor (except carpeting)
• One-inch clearance on all 4 sides
• Zero clearance from combustibles to the vent when concentric venting is used
• Electrical: 115V-60HZ-1PH less than 15 Amps with 24V transformer mounted and wired
• Outdoor reset with the addition of outdoor air sensor (limited temperature range available for EBP models)
  
• Control overrides outdoor reset when air sensor is faulty
• Easy-to-use viewing and programming menus
• 3-Character alphanumeric display of temperatures and fault codes
• Displays fault codes for supply sensor, return sensor, tank sensor (EBP only), outdoor air sensor, internal control, and lockout
• Displays 6 temperatures: supply water, return water, tank water (EBP only), heat exchanger temperature rise, outdoor air temperature (when outdoor reset is used), and calculated set point (when outdoor reset is used)
• Control LEDs indicate pump energized, gas valve energized and attempt to ignite 
• Ignition control LEDs show faults for erroneous flame signal, internal error and lockout
• Low water temperature feature - attempts to run the pump when supply water temperature falls below 39°F
• Built-in circulating pump and by-pass loop
• Equipped with anti-condensing controls
• Pump exerciser to ensure pump remains free from corrosion
• Built-in safety limit
• Copper finned, cylindrical tube design heat exchanger brazed into ASME bronze headers
• EBP united store 20 gallons of boiler water to provide instantaneous domestic hot water production through a brazed plate heat exchanger, with DHW priority
• 20 Year limited warranty
