Water heater foam dam and component cover and method for covering a component of a water heater

摘要

A foam dam is provided for use with a water heater having a tank and a jacket together defining an annular region. The foam dam includes a central region having a surface configured to cover a component coupled to the tank. The foam dam also includes a perimeter region extending from the central region. The perimeter region of the foam dam defines a surface to at least substantially traverse the annular region between the tank and jacket of the water heater. The perimeter region is configured to substantially prevent foam insulation from flowing into an area proximate to the component.
