Small Insert Ideas?

I want to install a wood burning insert in my old prefab (will have 20+' fully insulated 6" SS liner), but it's pretty small and it has a decorative arch that's going to make installation a PIA. I've researched a few models that might fit, but I was wondering if you guys know of any others. My wife really wants it to be flush, so I've been looking at...

Lopi Small Flush Hybird-Fyre (and other Travis variants)
Regency CI1200 (has no blower, CI1250 with blower is too tall)
Jotul C350

I thought a Buck 21 would work well without a face plate, but it appears to be a hair too deep to sit fully within the prefab.

Any ideas or comments would be appreciated.

Here are some pics and measurements of the fireplace and the arch...





Thanks!

Majestic, I think. Not positive.

Is there an easy way to identify the model of this prefab? Since it appears to be a radiant unit, the brick work is covering the tag. It's an interior fireplace too, so checking the back of it would require tearing out a wall in the room behind it.

As for heating requirements, it really only needs to heat a small area, and it's supplemental heat anyway. It's situated in the second level of a small four-level split, so it's basically just a sunken family room. I can't remember the exact dimensions, but the room itself is no larger than 25'x20'. There's an office, a bathroom, and a hallway on the same level, but the entire area comes nowhere close to 1000 sq ft. I have a freestanding stove on the third level that can easily heat everything else above it, so I think a small firebox will work just fine, and reloading every few hours isn't a huge concern for me...neither is not having the ability for an overnight burn. In fact, I might not even need to run the blower very much once the surrounding brick work heats up.

I am wondering if that is a metal fireplace shell and not a ZC. Is the backside masonry or stone or steel? It might be worth making an exploratory view hole on the backside wall that can be patched.

The sides, bottom, and top are metal. The back wall appears to be two stacked refractory bricks. The exploratory hole is a good idea.

If the backside is a sheetmetal box then it's a ZC. If masonry, it is likely a steel shell fireplace.

Thanks. I will have to double check when I get home, but I think there's a small metal lip over those refractory bricks in the back holding them in place, so I'm guessing that there's a metal wall behind them, since a metal wall extends upward from that lip towards the flue.
