Masonry thimble through log wall setup help

[SFFS47]

Hello all!
Been lurking for awhile researching for wood stove setup. Looks to be some great knowledge on this site.

So here's some questions I have. Including pics for some clarity. Have a existing engineered wall thimble around masonry pipe. Like to retain that if possible. Wondering safest way to connect to masonry, stainless single wall with furnace cement? Connect a double wall adapter to that,then add 6-8 increaser? Masonry pipe is just a bit over 8". Stove will be offset from flue connection, was thinking two adjustable 45's. Any direction 8s greatly appreciated.

Stove won't be main source of heat. Have a nice rice coal Keystoker for main winter heat. We would like to use to cut the chill at night for fall and spring and for when the mood hits up and power outages etc. So putting in a new chimney pipe in old chimney isn't in budget now.

I don't know what brand thimble that is, but most are going to need at least 2" of clearance from any combustible. This thimble appears to be right up against the wood. Removing it and stepping down to a 6" insulated thimble might be able to achieve proper clearances.

This one needs a 13.75" x 13.75" opening.

Insulated Chimney Thimble

The Insulated Chimney Thimble is intended for use in conjunction with any residential and building heating appliance burning gas, liquid, or solid fuels. The thimble adjusts to accommodate wall thicknesses 5" to 14".

Heres a picture with the frame removed and the space that's around it. At work so can't give exact measurement, but the insulated ring is 2" for reference. Would like to use e siting thimble if possible to save some money. Hoping for some insight if it will work.

I don't know the product or if this is homemade, so I can't comment on how safe it is or not. bholler may be able to identify it, but I can not.

It looks like a factory made piece but I don't recognize it at all

Thanks for the responses. I may just remove and bite the bullet and start fresh with new thimble.

That's the safest bet

Quick question, if you are able to help. Once installed, can I use a duravent double wall adapter and attach a increaesr and run rest of double wall pipe?

Is the stovepipe 6"? If so, why an increaser? It may need to stay 6" to meet the thimble's clearance requirements.

Why an increaser? If you need 8" put in an 8" thimble

Thimble would be 8inch to attach to t8 inch Terra cotta. Would need to attach 6 inch stove pipe to it from stove. Just wondering best way to do that.

Stovepipe will be 6". The terracotta pipe going into chimney is 8" where I would connect the insulated thimble originally suggested. Looking for some guidance on connections from there to get to stove.

Are you replacing the insulated thimble with a new one?

It was suggested, since existing in one in my pictures wasn't recognized. Looking to keep old terracotta setup and add the new thimble, which I am assuming will need to add increaser from stovepipe(6")where I would connect into the new thimble(8"). Because terracotta is 8" into chimney.

You would be eliminating the terracotta crock into the chimney and replacing it with the stainless one you then seal it to the clay liner with refractory cement.
