I currently have a zero clearance propane insert (ventless).  I haven't used it much due to propane is just as expensive as electric but when I have it will heat the entire house if I put some effort into moving the heat around.  Behind the insert is just building material.  I went to a regency dealer to discuss an install and he told me I would have to rebuild the entire fire place and install a free standing stove.  I was under the understanding that i could rip out the current insert and install a pellet insert with direct vent.  Most manufactures offere a zero clearance "shroud" or some could be installed as a zero clearance if installed with proper clearances to combustibles, but maybe I am not understanding "zero clearance" .  The insert opening is 32"t x 30"w x 20"D.  So my main question is can I install a pellet insert.  I do have another room that I can install a free standing stove with direct vent but the wife isn't buying into that idea.  I have included 2 pics of my current set up.  Sorry can't get the second pic to rotate when uploaded.  Any info would help.  Thanks.
