Converting prefab to wood stove

[steveb5004]

I plan to tear out my FMI 36" prefab corner fireplace this summer and hook up a Buck Stove model 74 freestanding stove. My measurements line up and I know I can do it; my only question is about the chimney. I know this has been discussed in previous posts, but I was hoping for a more specified answer. I'm hoping to save the existing chimney and line it if possible. I've read it's possible, but is it generally worth the effort? Here are a few pics, started with a look up my current chimney: it's double wall, 10 inch inside diameter galvanized steel...I would need to reduce it to 6 somewhere before I get to the stove:

The Buck Stove I'm installing...6 inch pipe.

Current fireplace...I'll be tearing out the entire corner back to the studs, hanging plywood and stone veneer on top of that. I'll have plenty of clearance every direction with the 6' x 6' pad I'm building.

I don't know exactly what the prefab looks like behind it, but it's original to the home and there is an online manual and parts are still available:

I seem to be able to get any parts I might need, and I will be tearing out the entire corner and doing everything custom, so I'll have more flexability in using a recessed ceiling box if necessary or any other adjustments. And again, I would be putting a liner up the existing chimney.

If I don't do this and opt for all new chimney, pipe and ceiling box, can I at least use the same roof flashing? I suppose that would depend on the chimney I buy, but that should be able to work, right? The current one appears to be in fine shape, although I don't know the flashing's exact diamter.

Many thanks in advance.

if you take out the prefab unit there usually will not be much of anything supporting that chimney. I would recommend using a new class a chimney.

Ya, that chimney is sitting on the fireplace. It really needs to go, it'll be so much easier and just isn't safe to reuse.
You will be able to reuse that flashing. I've done half a dozen or so just like yours. Sometimes I need to use an extra storm collar pulled down tight, then one used in the traditional manner above it. Because the hole in the existing flashing is gonna be pretty big, but it'll work with a little creativity.

Thanks, I was on the fence but you've convinced me. I've priced all new and I'll be right at $1,000 for a complete new chimney system. That's worth peace of mind to me.

Where are you in Ohio? I just got a new 22 guage stainless steel chimney cap (63"x28") for $200 from a guy in Wilmington, he did a great job as it popped right on. PM me if that's something you're interested in and it's close to you and I'll give you his details.

Sorry if my suggestion goesn't fit your setup.. I couldn't access your pics for some reason.
