clearances for fireplace/hearth installs of freestanding stoves

For those paying attention, I've been talking inserts on here for a month, and after all my research and questions, I bought one that it now turns out we won't be using because it will require hearth modifications to an extent we don't feel like doing right now, and it would end up an ugly setup if we did it "right". SO, the beast is back up on CL and we are now in the market again. (I am a miserable failure, lets just get it out there. - hanging head in shame.)

It does not seem that most other inserts would have the hearth issue that our particular stove had, but my husband is now taken by the idea of a freestanding stove on the hearth. (We were quite taken by the morso 7110 when we saw one although I would like something that at least claims to heat our particular square footage. 1430sq.) I suppose it would be one with a rear exit so it would not have to be backed very far in. I am really confused though about how the clearances work. For a mantel surround, would the side pieces be subject to the same clearances that a sidewall would be? And for the back clearance, are we then talking about the back of the fireplace being the back wall, or the actual wall?

The fireplace opening is 32" tall by 36" wide. The inside of the mantel trim is a little less than 1.5" thick, and it's 39" tall by 49.5" wide. I am not opposed to mantel/trim shields but I have no idea how one even determines the clearances for freestanding stoves that are installed in fireplaces.

Thanks.

Thanks, I appreciate the reply! But I do have a wooden mantel with a wooden surround that goes all the way around the fireplace opening, so there's a masonry fireplace with a pretty big opening, then about seven inches or so out from that, there's wood trim. If this was an insert, I could figure out from the listed clearances if that's too close, but I am not sure here whether I could do shields or whatever or whether these pcs of trim and mantel wood have to be treated exactly as if they were a wall that the stove needs to be removed from.

Ditto, would love to see the setup!
Wish that the picture gallery was categorized to some extent so that when someone says "mantel shields" or "flush hearth" or etc we could just go right to all the great pics! I know I have seen some great images on many threads but I can never find them when I need them!

I did find some freestanding stoves that list clearances for a hearth/fireplace setup, but most don't.
