Hey all. The front wall of my hearth/chimney has had several layers of brick/river rock installed on the face. therefore, when installing the insert, the faceplate surrounds(top/side slide walls) didnt quite reach the screw that attaches the faceplate to the firebox. I,being the creative ^%$#&nut; that I am, extended the back of the faceplate with 18 ga. steel riveted onto the sides/top of the faceplate where it attaches to the firebox. This worked fine, and the faceplate is secured in place. The only difference is the insert itself sits in the existing fireplace a few inches more than it normally would. This should not really affect the performance , should it? It seems absolutely fine, as inserts throw their heat forward and the blower blows up and over the top of the insert,anyway. Ive had no problems. Im just wondering what you guys think.
