Abstract
A water heater includes a lower skirt ring (10) supporting and spacing an inner storage tank (2) above a support surface (10a), a flange (44) extending radially outwardly from the sidewall (42) of the lower skirt ring, an outer jacket (12) around the inner storage tank and spaced outwardly therefrom to define an annular cavity space (22) therebetween and extending downwardly past the flange, and a seal provided by fiberglass (46) secured by a band (48) to the inner storage tank above the skirt ring and drapped over and around the edge (50) of the flange to form a dam between the flange and the outer jacket sealing the annular space. The dam prevents leakage of liquid therepast during foaming insulation.
