Exterior clay 6x10 chimney, EPA stove - double wall pipe worth it?

[burnt03]

Installing an EPA stove in the insulated basement, connecting to existing exterior clay tile chimney (6x10... about 23' high). I know that I should be lining it but don't have the cash right now so going to try a season without.

Will only have around 4-5' of stovepipe up and out. Read on here that double wall will allow for a better draft with the hotter exhaust.... is it worth it?

Thanks

An exterior 6 x 10 chimney is not likely to draft very well; and I don't think that 4-5' of double wall pipe is going to help much.

However, if you intend on lining the chimney in the future, then invest in the double wall pipe now --'cus you will want it later!

BTW, you won't get a 6"SS liner down that 6x10 clay liner. I just went through this myself. I ended up breaking out the entire clay liner so that the 6" rigid would fit. I had a welder build me a tool to do this --made the job much easier!! I'll never use the tool again, so if you are interested in it, I'll sell it to you cheap!! I live in Coldstream (Vernon).

It's worth a try. The 6 x 10 might work out ok. You may get a better result from softening the 90 degree turn, if you can use a pair of 45s with a short connector in between.

Ok, you've got me curious. How's a tool like that work/made? 23' rebar with a big chisel on the end?

Another alternative would be Duraliner oval liner. It's pre-insulated and comes 7 3/4" x 4 3/4" OD for this kind of situation. The product line is robust with options for most any installation.

Your guess is pretty close! I got the first 7 or 8 feet out with a long bar and a hammer - but couldn't go further 'cus the bar wasn't long enough!
The welder made me a 9.5' chisel from 3/4" pipe. The chisel is about 4" wide and has an angled piece welded perpendiclar to the chisel. He also made me 3 -3.5'extensions - so about 20 feet in all. got pretty heavy when all the extensions were attached. Was still hard work, but actually went quite quickly.
cheers!

lol, I guess.

I'll definitely keep it in mind when it comes time to decide about the liner. Thanks
