Finished up the install on the F500 yesterday. It looks great on the slate hearth that I layed! I started the break in process too. Yesterday afternoon I started a small fire in it with newspaper and kindling. I forgot to get a thermometer and didn't wanna drive 20 miles into home depot to get one, so I kept it small. I let it cool and started a second fire with some lumber that I split up. I let that fire get a little bigger and added an oak knot that I had laying around. It burned for about 45 to an hour. The stove felt like it was around 300 degrees. Tomorrow I am gonna get a thermometer and do the final 400 degree break in. I will post some pics tomorrow.
