Abstract

A water heater tank assembly having a shell with top and bottom heads welded in opposite ends thereof. The heads have aligned flue tube mounting openings therein in which metal collar members are welded. Flue tubes are mounted in and welded to the collar members. The collar members serve as a heat sink to prevent damage to the glass lining on the shell, head members and flue tubes during the various welding operations.
