A.O. Smith® Cyclone® Xi™ Gas Water Heater, Series: BTX-100, 100000 Btu/hr Heating, Liquid Propane, 1/2 in NPT Gas Connection, 50 gal Tank, Power Direct Vent, 387 gph at 30 deg F Rise Recovery, 96% Energy Efficient, 3/4 in NPT Water Connection, 150 psi, 181 deg F, Tall, Ultra Low NOx: Yes, ASME(Yes/No): No, 22 in Dia x 66-3/4 in H
- Advanced electronic control
- Exclusive A. O. Smith® designed touch display control system
- Built-in diagnostics and operational information
- Operates at 96% thermal efficiency, which saves money on operating costs compared to a standard 80% efficient gas water heater
- Equipped with condensate drain tee
- Helical internal heat exchanger
- Spiral heat exchanger keeps hot combustion gases in the tank longer to lengthen the heat transfer cycle
- Positioned in the center of the tank for more even heat distribution
- Spiral design reduces lime scale formation on the heat exchanger to maintain high efficiency operation over time
- Combined vertical and horizontal runs terminating through the roof or an outside wall. Vents using PVC, CPVC or polypropylene piping. Canadian installations require ULC S636 approved pipe for venting
- Side-mounted hot and cold recirculating taps
- Allows Cyclone® Xi to be installed as part of combination space heating/water heating applications
- Top fired ultra-low NOx gas burner
- Enhanced Ultra-low NOx burner complies with SCAQMD Rule 1146.2 and other Air Quality Management Districts with similar requirements for NOx emissions of less than 14 ng/J or 20 ppm
- Provides superior corrosion resistance compared to industry-standard glass lining
- Coregard™ anode rod our anode rods have a stainless steel core that extends the life of the anode rod allowing superior tank protection far longer than standard anode rods
