Gonna take some better pics when I get home but figured I would ask the stupid question. Looking to put a insert into my existing fireplace but having trouble finding something I like that will fit. My question is that there is an existing fireplace installed right now, the damper is already removed (rusted out) and the doors are very easy to remove. The firebox is steel and is restricting the size of the the insert I can put in as after 15" deep the back slopes up.

Can I remove this steel box? Is there masonry behind it? I tap on the steel and it sounds like there is room behind it. I will open it up when i get home and take better pics for you. This is the only pic i have available of the outside

Without seeing a better pic of the inside, it's hard to tell EXACTLY what you have, but if the venting was metal, it's probably a Zero Clearance (ZC) fire place. Chances are that there is no masonry behind it. ZC boxes are usually framed in with lumber or steel studs. Look inside the opening - behind the doors - for a rating plate. If there is one, & you can read it, let us know what it says. Also, if the venting has already rusted out, you're going to have to rip out that whole thing anyway. You should maybe start looking for EPA rated ZC fire places to install in that location & forgo an insert.

OK I will post some better pics tonight. If it is a ZC fireplace that means I have to open the whole wall to remove and replace it? I can install a ZC fireplace with the existing clay flue?

Clay? If there's clay tile in there, then it's not a ZC box. What does the chase/chimney outside look like? is IT masonry or is it framed & sided?

really dont want to rip the whole thing out, seems the enviro 1200 would fit. Is it acceptable to put an insert into one of these things?

Were you able to find an ID plate just inside the door near the bottom? Does your masonry chimney flair out near the bottom to the size of a fireplace or is it just the straight run right down to the ground?

We are all just guessing. My GUESS is that it is some type of pre-fab fireplace vented into the flue in the masonry chimney. Until you either find the manufacturer's plate or some way to see what is inside I don't think anybody here will be able to help you.

Until you know for sure what is there it will be hard to comment on whether or not it is suitable for any insert.

the flue is already removed (rusted out)
I think this is what is confusing. Please explain in greater detail. Is this on an exterior wall? If so, post a picture of the outdoor side too.

Was there a steel liner running up the clay flue in the masonry chimney? Were there two steel liners (one for the furnace and one for the fireplace) in the same clay flue or two clay flues each with a liner? Lots of pictures of everything will help...

No steel liners in either flu just clay. both separate clay flues in same chimney

Ahh damper, that makes a difference, sounds like a masonry fireplace now. If you feel sure you won't use the fireplace ever again you could try cutting out a piece of the metal and see if brick is behind it, you got a carbide hole cutter sitting around?

I have seen people remove the metal to get a larger cavity to insert an fireplace insert into, masonry is masonry if you meet the clearance to combustibles.

OK, thanks for clearing up the confusion. That dog does look intense, must have zombie xray vision or he found a radiocactive isotope out in the north 40.

Give us the complete measurements for the fireplace. height & width, front and back and depth, top and bottom, we'll see what fits.
