Got the Clydesdale in and have a bunch of Roxul left over. What are you thoughts on shoving some batts in there against the fire brick? Up against the back and side walls? Could this be an issue with the insert possibly causing it to overheat?

Im not sure its needed, with the way an insert is constructed with outside jackets etc. While im sure it wouldnt hurt either. I would think between the opening and surround would keep warm air in the room, its not like its going anywhere with insulation packed in the flue.
I would be inclined to let some of the heat radiate to the stone/hearth, thermal mass would hold and release it longer than the stove would.

My thoughts are the masonry robs the heat back there and is unable to radiate it back to the room.
By insulating those walls, more heat stays in the airspace between the heat shield and the cast iron.. subsequently blown into the room by the blower.
I'm just concerned about the insert itself getting too hot.

You'd probably be OK doing that unless the power went out. Then w/ zero ability to remove heat from that insert that is blazing and a blower that is silent you'd be more apt to overheat the stove and the blower unit itself.
I wouldn't be interested in doing it. I'd say if it were going to be that much of a savings that the insert manufacturers themselves would be shipping an insulation blanket to be placed around the stove, like a dishwasher or built in oven has.

If it's an outside chimney I'd stick some in the back. My old fireplace use to get frost on the rear of the fireplace when not in use.

Not sure if you would consider a chimney inside an unheated garage "outside". I never remembered unusually cold fire bricks when we weren't burning.
I have a Regency I3100. Have run it first two years without insulation and have run it two years with insulation all around top and sides. I would guess at least a 15% difference in efficiency. I have an outside chimney and have not had the power go out. If it does and I'm home I have an inverter to run off batteries. If I'm not home??? We'll see how it makes out it radiates pretty good with the blower off.

You should be fine without it then but if you have extra I don't think it will hurt anything.
Maybe you should email Hearthstone and see what they say about this? It's a good question and I can see the benefits as well as overheating concerns. I forgot who the contact is over at Hearthstone, maybe PM Highbeam, I think he knows?
I have the phone number. I talked to engineering once before and they were very helpful. I had to leave a message this time.
Hmmm, makes me wanna take all the insulation I have shoved around my insert out. Good call on callin them
