- System Sentinel™: All models employ a diagnostic panel utilizing light emitting diodes (L.E.D.), corresponding to the number and location of each heating element. L.E.D.’s are energized when the electric elements are operating. An unlit L.E.D. pinpoints the exact location of a non-functioning element, making element operation diagnosis simple and positive.
- ASME Certified: The tank's construction along with the factory installed Temperature and Pressure (T&P) valve meet ASME's stringent standards for composition and construction, allowing for installation in environments where ASME certification is required.
- Direct Spark-to-Pilot Ignition: This energy saving feature only ignites the pilot when there is a call for heat. This equates to a lower gas bill, as water is only being heated when it is needed.
