How hot can a rug get in front of an insert? I have the same rug but I got an insert that sticks out 9.5 inches more and it gets about 180 degrees while I'm burning the stove. Didn't have a problem with the fireplace but the stove is a lot closer to the rug.
To answer his question on this one though," How hot can it get." When it burst into flames from a spark when your reloading ya dont wana know. Extend the hearth pad. Weather it meets stove requirement's or not.
