Heat Barrier?

My Harman Mark 3 is working well. The wall is getting a bit hot. I was looking to put something to help block the heat. Any ideas that might work would be help full. My stove is a little closer then the manual would like it to be, That is the only place it would work.

Thanks, Billy

You can make a heat shield out of backer board and tile,or use a piece of metal or aluminum and paint it or buy one of those heat shields that are sold at stove shops or the bid box stores or Tractor supply. What ever you use be sure to put metal spacers between it and the wall to hold it away from the wall about an inch.

my stove is well within the guidlines for installation but the walls on the side used to get quite hot (about 3 1/2 feet away) so I put a standup fan next to it on the hot side and run it on medium and the walls are now much cooler and the air circulates into the rooms better. I have it set so it washes some of the air off the exterior of the stove- another benefit.

As Gambler said, Sheet metal held one inch away with copper tubing spacers. Keep the bottom one inch off the floor.

Durarock,or hardibacker,it's cement board with no paper,can't burn.Bought steel framing studs,nail them to the wall(cut to length of your choice),screw the cement board to the studs,studs are plenty wide if nailed flat to the wall and only 1.5 inches gap between cement board and wall,3 by 5 ft most common cement board size,also available in 4 by 4 ft.They make 4 by 8 ft but loews,and home depot and the other places around here don't carry the larger size.The steel studs make a good fireproof backing at the seam where 2 sheets of cement board butt together.Keep the insurance screws happy.This stuff is commonly used behind tile bathroom/shower walls cause it don't rot,but it don't burn either,meant to be tiled over,but if the wife isn't too picky dull grey isn't terrible to look at and it makes the stove stand out.

If you already meet the required clearances then I don't know that you need to worry about spacing or thickness of the metal. But if you are reducing a clearance you have to have no less than 24 gauge sheet metal with at least a 1" gap between the metal and wall or metal and unit.
There was a previous post here that had specs from USG about Durock. I used this in making my "shroud". Very helpful!
