Features

Features

 N/A
  • Induced Draft Built-In Blower - The blower is built into the top cover, factory mounted and wired. Ideal for installations where negative pressure is present in the building. Blower proves draft prior to ignition. No drafthood or barometric damper required.
  • Metal Venting - Uses standard metal single wall or double wall type "B" vent. Can be commonly vented with Category I appliances. Vent connects directly to the blower outlet. Perfect choice for retrofit and upgrade installations.
  • Water Connections - For ease of installation, all BCG3-NOx feature water connections on the top, front, and rear.
  • Glasslined Tank - Our proprietary slush coating is applied after the complete tank has been assembled to give a seamless barrier against hot water corrosion. Maximum working pressure 160 psi.
  • Installed Cost Savings - When multiple BCG3-NOx units are exclusively used in a vent manifold, use the National Fuel Gas Code Table 13 Fan Sizing Charts to determine vent diameter and specifications. The BCG3-NOx with its internal induced draft blower enables safe use of smaller vent diameters. This feature can save hundreds of dollars in installation costs.
  • Fully Automatic Digital Controls With Safety Shutoff - Accurate, dependable control system. Manual reset gas shutoff device for added safety. Maximum inlet gas pressure is 14" W.C. Minimum gas pressure is 5.2" W.C. Natural Gas, 11" W.C. Propane.
  • "Environmentally-Friendly" Non-CFC Foam Insulation - Saves fuel, helps reduce standby heat loss.
  • Jacket - Heavy gauge steel finished with a baked enamel finish over a bonderized undercoat.
  • Fully Tested for Safety and Performance - Design certified by the Underwriters Laboratory for 180 ºF hot water service. Meets rigid requirements of the National Sanitation Foundation Standard 5 when equipped with optional leg kit. Certified for use on combustible flooring.
  • Easy Cleaning - Handhole cleanout allows access for easy cleaning.
  • Anodes - Long-life, stainless steel core anode rods.
  • Intermittent Ignition Device - Eliminates standing pilot. Provides flame failure response in less than one second. Power ON/OFF switch.
  • Easy-to-Install - Completely factory-assembled. Only gas, water, vent and electric connections need be made. Provided with drain valve.
  • Plug Kits - Pipe nipples and caps are included to plug unused water connections.
  • Approval Ratings and Certification - All models meet or exceed the thermal efficiency and standby loss requirements of the U. S. Department of Energy and current edition ASHRAE/IESNA 90.1, C.E.C. California Energy Commission and comply with Texas requirements for Low NOx emissions.
