No.... in most cases depending on the size of your liner and a crapload of other things they will all mention.... the basic answer to me is "NO".
dont make the mistake of installing ANY kind of combustible material inside around or near or "between" the masonry fireplace and the fireplace insert. (i cant tell you how many times ive seen people use straping or 2x4's someplace in their to screw or mount something to).
