The TX1 condensating water heater combines tankless water heating with a tank to deliver exceptional performance. Capturing the efficiency of a tankless engine and the storage capacity of a 119 gallon storage tank, the TX1 offers the best of both worlds. The integrated A. O. Smith CT-199 Commercial grade condensing tankless water heater delivers 96% thermal efficiency with a modulating burner and a commercial grade Copper heat exchanger for superior Heat transfer and a secondary heat exchanger constructed of 316 Grade Stainless Steel. With an advanced electronic control controlling the pump and tankless units, the TX1 offers the best in energy savings. Certified to NSF standard 5 by Underwriters Laboratories and capable of delivering 180° F (62°C) water for sanitizing, the TX1 can handle anything thrown its way.

Have a condensing tankless with modulating burner as the heat source; 7. Be approved for 0˝ clearance to combustibles.

The control shall be an integrated solid-state temperature and ignition control device with integral diagnostics, graphic user interface, fault history display, and shall have digital temperature readout. 1. All models are design certified by Underwriters Laboratories (UL), Inc., according to ANSI Z21.10.3 - CSA 4.3 standards governing storage type water heaters; 2. Meet the thermal efficiency and standby loss requirements of the U. S. Department of Energy and current edition ASHRAE/IES 90.1; 3. Complies with SCAQMD Rule 1146.2 and other air quality management districts with similar requirements for low NOx emissions; 4. Complies with NSF Low Lead Standard.

For Standard Power Venting: Water heater(s) shall be suitable for power venting using a (3˝ or 4˝ ) _______ diameter PVC pipe for a total distance of (70 ft or 100 ft.) ______ equivalent feet of vent piping. For Power Direct Venting: Water heater(s) shall be suitable for power direct venting using a (3˝ or 4˝ ) _______ diameter PVC pipe for a total distance of (70 ft or 100 ft.) ______ equivalent feet of vent piping and (50 ft. or 120 ft.)______ equivalent feet of intake air piping.

Operation of the water heater(s) in a closed system where thermal expansion has not been compensated for (with a properly sized thermal expansion tank) will
void the warranty.
