Needing a heat deflecting to reduce clearances. Have not built my mantel yet so building around a heat shield if I had to would not be a problem. My clearance call for 30" above top of unit. Wife doesn't like the way this would look so I'm looking for something to reduce the clearance by 5 or 8 inches would be perfect. Wondering how much the clearance would be reduced by a bent piece of sheet metal attached to ZC cabinet have access to all the sheet metal I need so that is not a problem. If any one has pics of theirs that would be great. Thanks in advance
