A hot water tank construction, parts therefor and methods of making the same are provided, the hot water tank construction comprising a hot water tank having a wall provided with an opening therethrough and a spud carried by the wall and having an opening therethrough that is disposed in aligned relation with the opening in the wall, and a fuel control valve unit having a shank provided with a portion thereof disposed in the opening of the spud and being interconnected to the opening of the spud so as to be carried by the wall, the opening of the spud having axial securing structure therein, the portion of the shank having axial securing structure thereon, the portion of the shank having been axially pushed into the opening of the spud until the portion is in a predetermined position thereof whereby the axial securing structures cooperate together to interconnect the fuel control valve unit to the spud.
In a method of making a hot water tank construction comprising a hot water tank having a wall means provided with an opening therethrough and a spug carried by said wall means and having an opening means therethrough that is disposed in aligned relation with said opening, and a fuel control valve unit having a shank provided with a portion thereof disposed in said opening means of said spud and being interconnected to said opening means so as to be carried by said wall means, the improvement comprising the steps of forming said opening means of said spud to have axial securing means therein, forming said portion of said shank to have axial securing means thereon, and pushing said portion of said shank axially into said opening means of said spud until said portion is a predetermined position thereof whereby said axial securing means cooperate together to interconnect said fuel control valve unit to said spud.
In a hot water tank construction comprising a hot water tank having a wall means provided with an opening therethrough and a spud carried by said wall means and having an opening means therethrough that is disposed in aligned relation with said opening, and a fuel control valve unit having a shank provided with a portion thereof disposed in said opening means of said spud and being interconnected to said opening means so as to be carried by said wall means, the improvement wherein said opening means of said spud has axial securing means therein, said portion of said shank having axial securing means thereon, said portion of said shank having been axially pushed into said opening means of said spud until said portion is in a predetermined position thereof whereby said axial securing means cooperate together to interconnect said fuel control valve unit to said spud.
In a fuel control valve unit for a hot water tank construction comprising said fuel control valve unit and hot water tank having a wall means provided with an opening therethrough and a spud carried by said wall means and having an opening means therethrough that is disposed in aligned relation with said opening, said fuel control valve unit having a shank provided with a portion thereof adapted to be disposed in said opening means of said spud and be interconnected to said opening means so as to be carried by said wall means, the improvement wherein said portion of said shank has axial securing means thereon so that said portion of said shank is adapted to be axially pushed into said opening means of said spud until said portion is in a predetermined position thereof whereby said axial securing means will be adapted to cooperate with axial securing means of said opening means of said spud to interconnect said fuel control valve unit to said spud.
In a hot water tank for a hot water tank construction comprising a fuel control valve unit and said hot water tank that has a wall means provided with an opening therethrough and a spud carried by said wall means and having an opening means therethrough that is disposed in aligned relation with said opening, said fuel control valve unit having a shank provided with a portion thereof adapted to be disposed in said opening means of said spud and be interconnected to said opening means so as to be carried by said wall means, the improvement wherein said opening means of said spud has axial securing means therein so that said portion of said shank is adapted to be axially pushed into said opening means of said spud until said portion is in a predetermined position thereof whereby said axial securing means is adapted to cooperate with axial securing means of said portion of said shank to interconnect said fuel control valve unit to said spud.
In a part for a hot water tank construction comprising a hot water tank having a wall means provided with an opening therethrough and a spud carried by said wall means and having an opening means therethrough that is disposed in aligned relation with said opening, and a fuel control valve unit having a shank provided with a portion thereof disposed in said opening means of said spud and being interconnected to said opening means so as to be carried by said wall means, the improvement wherein said part comprises a shank fitting having a portion adapted to be threaded in a threaded opening of said opening means of said spud and having axial securing means therein for cooperating with axial securing means of said portion of said shank so as to be adapted to have said portion of said shank axially pushed into said shank fitting until said portion of said shank is in a predetermined position thereof whereby said axial securing means cooperate together to interconnect said fuel control valve unit to said shank fitting.
