Claim 3
Dependent Claim
64 words
The seating for a water closet as set forth in claim 1, wherein the bulkhead is located over the hinge area at one side of the water closet to thereby divide the adapter housing chamber into an enlarged inlet plenum and a diminished exhaust plenum, and wherein the fan means draws air through said bulkhead into said exhaust plenum and through said exhaust opening.
Claim 4
Dependent Claim

The seating for a water closet as set forth in claim 1 wherein there is means for selectively locating the bulkhead over the hinge area at either side of the water closet to thereby divide the adapter housing chamber into an enlarged inlet plenum and a diminished exhaust plenum, and wherein the fan means draws air through said bulkhead into said exhaust plenum and through said exhaust opening.
Claim 5
Dependent Claim
76 words
The seating for a water closet as set forth in claim 1, wherein there is means for selectively locating the bulkhead over the hinge area at either side of the water closet to thereby divide the adapter housing chamber into an enlarged inlet plenum and a diminished exhaust plenum, and there is means to reversibly insert the fan means into said bulkhead to draw the air therethrough into said exhaust plenum and through said exhaust opening.

Claim 7
Dependent Claim
101 words
The seating for a water closet as set forth in claim 1, wherein there is means for selectively locating the bulkhead over the hinge area at either side of the water closet to thereby divide the adapter housing chamber into an enlarged inlet plenum and a diminished exhaust plenum, wherein there are opposite and remote exhaust openings closed by selectively removable plugs inserted into the adapter housing and positioned to open from the exhaust plenum established by the selectively located bulkhead, and wherein the fan means draws air through said bulkhead and into said exhaust plenum and through said exhaust opening.
