I helped a buddy of mine today install a 6" 316ti ss liner in his chimney and hookup a mark I that I sold him up to it. He had a 12"x12" terra cotta liner which was too large for the stove. We measured and cut it to length which was 27', then wrapped the insualtion kit around it. He has a metal roof which was alittle hairy today with the stiff breeze blowing. Anyway we started at 10:00 am and I just got home about an hour ago. He had a fire going when I left. Another convert!

Your buddy is smart to put in the liner in. He'll be able to hold onto his coal fire for additional hrs per load and get better heat/damper control with that insulated liner. Give him a call & check to see how the unit is drafting/burning with this heavy rain storm we're experiencing. It's been raining since last night here is Eastern,PA as it is along the east coast. 34F.

I just talked to him Cap. It's doing great. He almost didn't go for the insulation kit as it was about $300.00 but I convinced him it was money well spent.
His wife is complaining it's too hot already. That sounds like it's working well.

My new chimmey which is 6" super vent insulated works so much better then my block 8x8 tile flue I used to have for 15 years.

I think every newbee burns it hot in the beginning..They don't realize the output from these small firebox's. I think this applies the guys who burned wood first especially.

Terry,

Where are the pictures?? We love pictures here, you know.

I have a Harman Mrk II. What kind of liner is this that you are talking about? I am heating about 2000 sq ft with my stove and have the draft turned back 5 turns, which is only about 1.3 turns from being closed the whole way. I can almost touch my class A chimney with a Barometric damper that remains closed. I didn't get a thermometer because at this point, I'm pretty sure I don't need one.
I think I got lucky with this stove and the instalation because when I went to pick up my first coal, the person who is a good friend of mine said I would need to keep the draft open at least half way on this stove. When I did this, the heat was intense, so I kept drafting it back. Now I can go 12 hours between each fill time without a problem.
But I am interested in this liner, if just to keep my burn time to a maximum and coal use to a minimum.

its a 6" 316 stainless ti flexible. It came from rockford chimney liners on the web. He has this stove on his fireplace hearth. The f/p had a 12 x12 terra cotta, outside chimney that was too large and cold to work well. It was alittle hard to take pics while trying not to fall off of his metal roof in the wind. Today I took him to get 2 tons of superior nut at our local supplier. I did take a pic of that which I'll post in a bit. He took some pics of me in his fireplace cutting out the damper housing too.

I can hold a hand on my stack unless I really have her fired up. Typically my stack temps run at 140F, maybe 160F while hot air will be at 200F. I'm also using a 6" ss liner. But I find the warmer I fire the stove, the closer my stack is to my hot air temps. i.e. If I throttle her up, I'll see 250F hot air and 240F stack. In other words, my wasted (stack) heat to usable heat efficiency drops.

I'm jealous! Two tons of Superior nut coal. I wish I could get my hands on Superior coal up here on the Tug hill in Northern NY. I am burning Blaschak and I am going to try some Kimmels. I would love to have the chance to come down in your neck of the woods this summer and pick up four or six tons of Superior. I would like to make it down for the summer meet and greet and discuss the possibility of making another trip down to purchase some Superior. I'm tired of the Blaschak and the shale, wood, and fines that comes along with it. I have a question: My chimney has a six inch stainless steel liner that is not insulated. Can I insulate it without taking out the liner? If I can't maybe insulate the very top to possibly help retain the heat in the liner. Just an idea. Its nice to hear another individual being converted to coal.

Why wait?

I was there on Saturday for 2 ton.

I'm several hours south of the superior breaker. I just happen to be lucky that my local supplier buys his bulk coal from Superior. I burned it up until this year when I bought a tractor trailer load. I was unable to get Superior at the time. I got Summit which seems to burn as well but has a larger volume of ash and much more fly ash. I prefer Superior.
Is your chimney an outside chimney or does it go up through the middle of your house? If it goes up inside the house, you don't need to insulate. Actually, if its working fine now and you have no draft issues I wouldn't worry about it. To install the insulation wrap you would need to remove the liner. If you could seal well at the bottom, you could drop some type of loose insulation material down around the liner and that would work.
My friend didn't have clue #1 about coal burning and he was relying totally on my advice for the liner. Since it was an outside chimney and his money buying it, I recommended the insulation kit. It was about $300.00 which seemed alittle high but in the long run, I think it was well worth it. His draft is great and the stove is burning well. He's hooked.
