A flue baffle for use in a hot water tank flue pipe which is disposed to be in contact with water contained in an inner tank of the hot water heater. A burner chamber is provided at a lower end of the inner tank. The flue baffle is comprised of an elongated rectangular metal strip which has a plurality of spaced circular metal discs disposed substantially transverse to the strip and to the longitudinal axis of the flue pipe. The metal discs are dimensioned to be spaced from an inner surface of the flue pipe. Two or more spacing nipples protrude from a circumferential outer edge of the circular metal discs and are spaced apart from one another for slight frictional engagement with the inner surface of the flue pipe to maintain a substantially constant circumferential passage between the circumferential outer edge of the discs and the inner surface of the flue pipe.
A flue baffle for use in a hot water tank flue pipe wherein said flue pipe is adapted to be in contact with water to be contained in an inner tank having a burner chamber at a lower end thereof, said flue baffle comprising an elongated rectangular metal strip having a plurality of spaced metal discs disposed substantially transverse to said strip and dimensioned to be spaced closely to an inner surface of the flue pipe, and two or more spacers protruding from a circumferential outer edge of said metal discs and are spaced apart from one another for frictional engagement with the inner surface of the flue pipe to maintain a substantially constant passage between said outer edge of said metal discs and the inner surface of the flue pipe.
