My regency wood stove insert is only one year old.  However, three of the brick on the bottom of the stove are flaking.  What I mean is the top 1/16" to 1/8" is breaking off the top of the brick.  The brick is not cracked and is still intact but that top layer is flaking off. Do I need to replace the brick or are they still ok.  Thanks for your help...
