Here are a few photos showing the new stove from the side. The positioning of the stove on the hearth extension was determined by two variables: leaving it sit out far enough for good access to the side door for loading, and far enough back so that the rear legs sat inside the fireplace since the fireplace extends down another floor and is supported by a huge footer. The hearth extension is brick, but the brick is sitting on the sub-floor with no foundation. However, there is a beam made up of two 2"x10"s running directly under the extension. For some reason the extension has a slope away from the fireplace. When we moved in 12 years ago I saw a 3/8" gap between the hearth extension and the fireplace and filled it with mortar. Since then it must have stabilized because that mortar joint has not opened up. If you look at the front legs of the stove you can see that I had to place 3/4" spacers under the legs to level the stove. I placed a level on beam I just mentioned, the floor joists, and the bottom side of the sub-floor from the lower level side and everything is level. So the only thing I can figure out is that something was used between the hearth extension brick and the sub-floor that must have compressed more for some reason out near the edge than near the hearth where it is at the exact same height as the hearth. Also, my living room floor in front of the hearth extension is level. When I laid laminate flooring a few years ago there was no sign of anything going on with the sub-floor in front of the hearth extension. One final note, the extension is solid brick and not built over a wooden box.

Thanks for the side view and all the information. This looks similar to my son's fireplace and your experience may be very helpful to him. I really like the side loading feature of the Jotul 600.

In earlier photos there is a discoloration due to the brick being wet. There was a shadow line from where my old insert surround had been that I washed off.
