Can you use this to extend a masonry chimney with double wall stainless.....

Can I use this:

to be able to add on to my 8x8 flue tiles with some 6" double wall stainless? Trying to hit the 10-3-2 rule.... masonry is in good shape, no cracks no fires.

Actually, you can transition from masonry to insulated using a masonry adapter. The issue often becomes supporting the pipe....and it does not look so great!

Any chance that my extendaflue (plug) will do the job? Look at the CC88 (I'll give you a heck of a deal - like end of season special).

What is the max extra height I could get with that? I would consider it, I just worry that with my chimney I may need to go up quite a bit, as i have a one floor chimney, probably only about 12' maybe from the top of the stove. And I have a 90 degree bend. I'd certainly consider using that, can you PM me a price? BTW, since you're in my thread now and reading, awesome website, I've learned more here in a month than I have in 4 yrs of burning wood/talking to people.

Thanks,
Ed

Why wouldn't you extend this chimney using the same construction technique that was used to build it in the first place? It appears to be built of standard cement chimney blocks with a tile liner. That seems like the cheapest option and it will look intentional.

EDIT: Here's a shot of the chimney again.

Here is a pic of the Masonry Adapter way of extending a masonry chimney. It makes it very easy to add/remove sections if needed.

Well my worries there are:

Being able to support the chimney laterally, it comes out of the roof quite a bit.

Getting the cap block off without trashing anything

And knowing what height to go to, I'm worried that not only the 10-2 rule is working against me but overall height

I'm still up in the air though, and continuing with the construction there is certainly still on the list....

Shove a 3-4 ft. piece of $10 galvanized 6" vent pipe in the top of the flue and try it out temporarily. If it makes a huge difference you'll have your answer.

As to support, is the chimney out of plumb? Best to ask a mason what he thinks. I don't think it will be an issue to go up 2-3', but it's good to get a pro's perspective.

I didn't see the picture when I posted last. That would look a little silly to transition to pipe there. I think I would try BeGreen's idea to see if it makes a difference and then look into Craig's extenders for a permanent fix.

Yeah good point on the temp solution, I'll try that, I have the old stove back in for now. The chimney isn't out of plumb, I just wasn't sure if there was a limit to how high it could go without being attached to the structure, maybe I'm worrying about nothing there. My neighbor(the house you can see in the pic) grew up working for his dad who was a mason, so I may ask him to come take a look.

Good plan. And if it gives peace of mind, ask him about strapping the chimney to the building.
