I have a Lopi 1750i insert, and I just ran across some old rebar on the property.  Would there be any benefit to just laying a few pieces down for wood to sit on, to get better airflow?  I know it would make cleaning a bit more of a hassle, but beyond that, any opinions?  I seem to remember seeing that some wood stoves explicitly tell you not to use a grate.  What would be the reason for such a warning?
