This A. O. Smith’s Signature 500 Series 40-gallon water heater is built to last. It features an electronic gas valve that provides precise temperature control for optimum hot water delivery without the need for an external power source. For your convenience, the gas valve also includes an LED status indicator for diagnostics reporting and a push button ignition to simplify the startup process. Energy Star certified, it operates at a 0.70 Uniform Energy Factor (UEF) which can reduce your energy consumption. With a built-in safety system, this model reduces the risk of accidental flammable vapor ignitions.
