Description
Features:
  • 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 - Rated Category I Appliance. Uses standard metal single wall or double wall type "B" vent. Can be commonly vented with other Category I appliances. Vent connects directly to the blower outlet. Perfect choice for retrofit and upgrade installations.
  • Water connections - for ease of installation, all BTNs feature water connections on the top, front, and rear
  • Glass lined tank- Permaglas┬« Ultracoat is the proprietary ceramic coating developed by A. O. Smith's ceramic engineers specifically for the heater. It is applied after the complete tank has been assembled to give a seamless barrier against hot water corrosion. The maximum working pressure is 160 psi.
  • Installed cost savings - When multiple BTN units are exclusively used in a vent manifold, use the National Flue Gas Code Table 11 Fan Sizing Charts to determine vent diameter and specifications. The BTN with its internal induced draft blower enables safe use of smaller vent diameters. This feature can save hundreds of dollars in installation costs.
  • Full 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 5.0? W.C. Natural Gas.
