An inlet du ct extends upwardly from the combustion air chamber and provides fluid communicatio n between the combustion air chamber and the ambient air from a predetermined heig ht above the combustion air chamber. Alternatively, a removable shroud may be emplo yed which includes an adjustable band adapted to extend substantially about the body of the water heater and between the floor and the body to form a combustion air chamber therebetween.
