What is claimed: 1. An article configured to distribute foam insulation between a water tank and an outer shell of a water heater, said article comprising: a body portion having a top end, a bottom end opposite the top end and two sides extending between the top end and the bottom end, said body portion configured to extend between the water tank and the outer shell of the water heater, said body portion at least partially defining a flow passage for foam insulation; opposed flap portions extending from the top end of said body portion; means for attaching at least one of said flap portions to the water tank; a trough defined at the bottom end of the body portion for collecting foam insulation, said trough being defined by a closed bottom side at the bottom end of the body portion and closed lower sides, each closed lower side extending from the closed bottom side and along at least a portion of a respective side of the body portion; at least one closed top side portion of said body portion extending along a portion of a respective side of the body portion and defined at an elevation above a respective closed lower side; and at least one outlet opening extending along a portion of said respective side of the body portion and defined at an elevation between the at least one closed to side portion of said body portion and said respective closed lower side of said respective side of the body portion, wherein, in use, foam is distributed through said outlet opening and into a region defined between the water tank and the outer shell of the water heater. 2. The article of claim 1, wherein said body portion at least partially defines two flow passages for foam insulation. 3. The article of claim 1, wherein said means for attaching each of said flap portions to the water tank comprises an opening positioned on both of said opposed flap portions to engage the water heater. 4. The article of claim 1, wherein said means for attaching each of said flap portions to the water tank comprises a plurality of openings positioned on both of said opposed flap portions to engage the water heater. 5. The article of claim 1, wherein in a separated state said opposed flap portions define a plurality of foam distribution inlets to facilitate uniform distribution of foam between the water tank and the outer shell. 6. A water heater comprising: a water tank; an outer shell surrounding said water tank; a foam distribution device disposed between said water tank and said outer shell, said device extending only partially around a perimeter of said water tank; and an insulation member disposed between said water tank and said outer shell and positioned below said foam distribution device such that a gap or a space exists between a bottom external surface of said foam distribution device and a top surface of said insulation member, wherein the gap is sized for receiving foam insulation to thermally insulate an area defined between the bottom external surface of said foam distribution device and the top surface of said insulation member. 7. The water heater of claim 6, wherein said foam distribution device includes means for attaching said foam distribution device to said water tank. 8. The water heater of claim 7, said foam distribution device comprising at least one flap portion, wherein said attaching means is positioned on said flap portion. 9. The water heater of claim 8, wherein said attaching means comprises an aperture positioned on said flap portion to engage a fitting disposed on said water tank. 10. The water heater of claim 8, said foam distribution device comprising opposed flap portions, wherein in a separated state said opposed flap portions define an inlet to receive foam insulation. 11. A method of assembling a water heater comprising the steps of: positioning an insulation member at a bottom end portion of a water tank; mounting a foam distribution device to the water tank such that it partially extends around a perimeter of the water tank and terminates at an elevation above the insulation member; delivering foam insulation into a body portion of the foam distribution device, through an outlet opening defined in the body portion of the foam distribution device extending along a portion of a side of the body portion and defined at an elevation between a closed too side portion defined along the side of the body portion and a closed lower side portion that is also defined along the side of the body portion, and into a gap defined between the water tank and an outer shell of the water heater; and attaching a cover to the outer shell of the water heater, thereby substantially enclosing the foam insulation. 12. The method of claim 11 further comprising the step of attaching a flap portion of the foam distribution device to the water tank with a body portion of the device disposed between the water tank and the outer shell. 13. The method of claim 12, said flap portion attaching step further comprising attaching a first flap portion and a second flap portion of the foam distribution device to the water tank. 14. The method of claim 11 further comprising the step of fastening ends of the insulation member together. 15. The method of claim 11 further comprising the step of stapling ends of the insulation member together. 16. The method of claim 11 further comprising the step of adhering the insulation member to the water tank by applying an adhesive to the water tank. 17. A method of assembling a water heater including a water tank positioned above a combustion chamber, said method comprising the steps of: positioning an insulation member about the combustion chamber; mounting a foam distribution device to the water tank such that it only partially extends around a perimeter of the water tank and terminates at an elevation above the insulation member such that a gap is defined between a closed lower end of the foam distribution device and a top surface of the insulation member that faces the closed lower end of the foam distribution device; delivering foam insulation into a body portion of the foam distribution device, through an outlet opening defined in the body portion of the foam distribution device and into the gap defined between the closed lower end of the foam distribution device and the top surface of the insulation member; and attaching a cover to an outer shell of the water heater, thereby substantially enclosing the foam insulation. 18. The article of claim 1 further comprising two closed top side portions, each closed top side portion extending along a portion of a respective side of the body portion and defined at an elevation above a respective closed lower side. 19. A water heater comprising: a water tank; an outer shell surrounding said water tank; a foam distribution device disposed between said water tank and said outer shell, said device extending only partially around a perimeter of said water tank, said foam distribution device including: a body portion having a top end, a bottom end opposite the top end and two sides extending between the top end and the bottom end, said body portion at least partially defining a flow passage for foam insulation; opposed flap portions extending from the top end of said body portion; means for attaching at least one of said flap portions to the water tank; and a trough defined at the bottom end of the body portion for collecting foam insulation, said trough being defined by a closed bottom side at the bottom end of the body portion and closed lower sides, each closed lower side extending from the closed bottom side and along at least a portion of a respective side of the body portion; and an insulation member disposed between said water tank and said outer shell, said insulation member positioned below said foam distribution device such that a gap or a space exists between a bottom surface of said foam distribution device and a top surface of said insulation member, wherein the gap is sized to receive foam insulation for thermally insulating an area defined between the bottom surface of said foam distribution device and the too surface of said insulation member.
