Abstract
An anode adherred to a flue pipe which consists of anodic metal like zinc, aluminum or magnesium flame sprayed in the form of a ribbon, strip or ring onto exposed metal at the upper end of the flue pipe beneath the upper head of a water heater. The anodic metal overlaps the glass coating on the flue at the joint between the glass and anodic metal and has a press fit with the upper head to eliminate any problem of corrosion at the joint area between the flue and upper head.
