  • 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
  • INSTALLED COST SAVINGS - When multiple BTL units are exclusively used in a vent manifold, use the National Fuel Gas Code Table 13 Vent Sizing information to determine vent diameter and specifications. The BTL often uses a smaller vent diameter than a natural draft water heater which saves on installation cost
