Good Morning! Our newly installed Matrix is in the center of the house. I noticed yesterday that the upstairs wall(s) surrounding the chimney are getting very hot. They give off wonderful heat to the upstairs but I started to get paranoid that they could be getting too hot. So, need I need some education here please! We had everything inspected prior to putting the insert in and we had a liner installed of course. I even feel like I can smell the fire a little when I put my nose to the wall. Is this ok? I am going to call the installer today to check. Thanks!
