Abstract
A water heater comprising a tank for holding water, a jacket surrounding the tank, foam insulation between the tank and the jacket, a heating element for heating water in the tank, and a thermostat mounted on the tank for controlling the heating element in response to the temperature of water in the tank. The thermostat includes electrically active terminals, leadwires connected to the terminals, an electric circuit reset, and a temperature adjustment dial. The water heater also comprises a protective shield for covering the terminal and preventing foam contact with the terminal. The shield includes a face portion covering the thermostat in spaced relation to the tank. The face portion comprises a first access port for providing operator access to the circuit reset cutoff, and a second access port spaced from the first access port for providing operator access to the temperature adjustment dial. The shield also includes sidewall portions extending between the face portion and the tank. Each sidewall portion has a rearward tapered surface sealingly engaging the tank, and a leadwire access port which provides an opening for routing a leadwire and which provides strain relief for the leadwire.
