I'd do everything possible to avoid a Stainless Steel liner I could. The flyash from burning coal is going to eat it alive. Before we found the forum and were educated we had a Class Stainless Steel chimney put in for the Mark II. It lasted all of 9 years.
We'll have to replace the whole thing before we'll be able to use the stove in the fall. The thimble is completely eaten through and the upright pipe has pin holes. The chimney cover had to be replaced due to the rust out. And that's with my having washed it out with baking powder every spring.
We would have been better off spending a little more and had a masonry chimney in. We don't know what we are going to do yet. We are planning to only be in this house for another 4 or 5 years. The next owner will probably not burn coal and maybe not anything except for ambiance. In all likelihood a Stainless Steel would last the entire stated 20 year lifespan.
We also have a masonry chimney that the Mark I is installed in. It is unlined. We've never had a problem with it as fly ash is not flammable like creosote. We just run a chimney brush through it in the spring.
I hope it works out for you, Lisa

Rockford Chimney Supply has quite a few kits that can be shipped direct.

You would want a 316 liner for coal. With that said, I agree with the others that a stainless liner should be the last option considered. If the chimney is in good condition, it would probably work just fine the way it is.
Also, if the chimney does not have an offset in it, you could actually have a clay liner installed. Might have to find an old timer that knows how to do it, but they can butter the ends and lower the tiles down from the top.

Yes , I know stainless is not the best option for coal but my curved chimney is in the middle of my high peak gothic revival house. I built a masonry chimney in my garage about six years ago with my brother helping me and turned out great but putting up a new one in my particular house would be a major undertaking .
Sal old mason here 40 plus years .Why not do this .Put 2 coats of mortar on the chimney by stuccoing .First knock off any loose cement .Than use a Portland an Lime mixture .First coat while wet scratch it before the mortar is dry .Like running a comb through the mortar .This leaves line for second coat To Bond To .Repeat stucco plaster first coat of cement to chimney .Scratch bonding lines on first coat of cement .Next day put second coat of mud on chimney .This Will Give You 20 Years of Holding Up .Or I will eat my hat .Jack

I burned wood in an unlined brick chimney & an unlined cinder block chimney.
Why are you worried about a liner for burning coal ? Are there big holes in the chimney ? Other than the hole at the thimble & at the very top ?

When I first considered heating with coal I also believed my chimney wasn't up to par. Boy I'm glad I was wrong about that. All I did was rebuild the top two courses of brick because it was quite fractured, but it probably really didn't even need that done to function properly.
Coal ash/fly ash becomes acidic when exposed to moisture, it actually forms sulfuric acid which doesn't bode well for metals.

Yep, that's exactly what he's saying.
