ABSTRACT:
A water heater comprising a tank to contain water to be heated and having a downwardly convex lower head. A flue extends upwardly through the tank and the lower end of the flue projects downwardly beyond the lower head. A burner having a substantially smaller cross-sectional area than the flue is located adjacent the lower end of the flue, and a locator interconnects the projecting lower end of the flue with the burner for precisely positioning the burner with relation to the flue. A layer of insulation is disposed on the outer surface of the convex lower head and extends radially inward to the projecting end of the flue.
