think of manifold as "solid"

technically manifold meshes must have exactly two faces on each edge, but blender will allow you to have only one.

so, if you delete one face from a cube it isn't solid or manifold... but blender will let you decimate it

however, if you extrude a single edge of a cube, you will have an edge with 3 faces and the mesh will be neither manifold, nor solid, and will not work with the decimator

shift+alt+m selects non-manifold edges [even ones with only one face], try to find the edges that have 3 or more faces and fix them.
