Brep tessellation produces gaps when using BRepMesh_IncrementalMesh

I am using BRepMesh_IncrementalMesh to tessellate B-REP surfaces read from step files. when tessellating shells, it is producing gaps between two shells.

The same step file I had checked with CAD Assistant, it renders the geometry with out any single gaps. 

How to avoid those gaps while tessellating ? 

I had attached images for your reference.
