Features |
N/A
Eighty plus percentage thermal efficiency affords lower operating costs on most models. 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 draft hood 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. 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 Fuel Gas Code Table 13 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. 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. Foam Insulation - Saves fuel, helps reduce standby heat loss. Jacket - Heavy gauge steel finished with a baked enamel finish over a bonderized undercoat. Easy Cleaning - Handhole cleanout allows access for easy cleaning. 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. Anodes - CoreGard™ long-life, stainless steel core anode rods. Plug Kits - Pipe nipples and caps are included to plug unused water connections.
