Abstract
A dam assembly to protect a component mounted on a water heater tank wall while insulating foam is injected between the tank and a jacket surrounding the tank, the dam assembly comprising an outer portion, an inner portion, and a frangible web connecting the inner and outer portions, the web having a strength sufficient to withstand force applied to the inner portion to press the dam assembly into an aperture in the jacket such that the outer portion surrounds the component between the tank and the jacket, and the web breaking under the application of a pre-determined force on the inner portion, allowing the inner portion to be at least partially pushed inside the outer portion to enclose the component within the dam assembly.
