I dont' know if i have a leak in the back wall of the stove or not...air is completely dampered down but seems like air might be coming in from the back...what do i use to fix this issue? Thanks for any ideas or help!!
Why do you think the back of the stove is the issue? Are there any cracks in the stones?
There are no outside and inside stones. It is one layer of stone. The stone you see on the exterior is the stone you see on the interior. There are no layers or air gaps.Cracks on the outside stones? Just seems like it is buring unevenly and faster in the back of the stove

So, if you think you have an air leak in the back of the stove, it should be easy to diagnose.
How are your gaskets on the side door?
Do you have an incense stick or a cigarette (gasp!) ? Even a candle or a stick match can be used to diagnose this issue. The incense or the cigarette will work better, as there is a continuous stream of smoke coming off them. Just pass one of them near where you suspect the air leak to be. The smoke will get sucked into the stove with the air stream. You can use a match or a candle, they just don't smoke as long...
Not to sounds stupid but i assume i go from the outside the incense?
The black riser tube that is in the middle of the rear of the stove is not gasketed
+1 on "goobering" the top and bottom seams.

It is very unlikely that you have a leak in the wall of the stove. Hearthstone uses actual metal bars with gaskets between stones. Door gaskets are a possibility. In my experience with leaky back walls of heritage stoves, mine was a leaker too, it is the secondary manifold system. The black riser tube that is in the middle of the rear of the stove is not gasketed, it just sits between the stove base casting and the bolted in place secondary manifold casting on the roof. The "seal" is just that white cement and as we all know, that stuff doesn't stick between iron/stone too well. The next leaky part of that system is the secondary manifold which is actually a split casting that squeezes the tubes. Fresh air can leak out and run down the back wall.
I mostly noticed jets of air blowing out and down from behind the connection between the top of the steel riser tube and the secondary manifold. I goobered rutland furnace cement over the gaps that shot flame which worked for several months at a time but was an ongoing maintenance issue.
Yes.
I had the same jet of air. I believe it was shooting down from the ungasketed interface between the riser and the upper cast secondary manifold. My fix was to buy the small tub of furance cement and take a blob of it out about the size of a tablespoon. Roll it into a pencil like shape and lay it on the crack between the back wall and the riser. Moosh it in place. I repeated the sealing around the entire top of the riser too. Can't hurt anything to overseal it.
Over time, the cement will fall off since the steel and the stone don't seem to expand at the same rate.
