Replacing masonry chimney with stainless in spring need advice

Hammer drill with chisel bit. Hilte are good

 

just found this

 

That's how you do it! The ole ball n chain (X2)

 

couple different kinds
read some guys made the chain ones without weights
looks easy to weld up either one

 

instead of installing a flex liner with insulation
could a rigid one be installed?
diff between 304 and 316stainless alloy
wrap with insulation or pour vermiculite or something else

 

Sure, if it will fit, and you can make the connections...

 

Slow and easy from the top down. Have someone at the clean out pulling chit out as it falls to the bottom. Get too much falling on top of the part doing the busting and you’ll get the whole deal stuck!

 

Very interesting how this is evolving
Now I'm thinking break up old flue liner- I'll weld up something to do it and make extension rods
New clean out door but opening will be much larger with removal of double door size of bricks. Then cut thru inner cement block, might even be able to get a stainless T in this way.
Rigid stainless stove pipe riveted together and insulated. Fed down from top. I think I could get 12 ft pre made and lifted to drop down. Install T and hook up to stove. Insulate around T put cap under it.
Rebrick outer chimney to fit new clean out door.

thinking about welding up a custom clean out door with gaskets. 8x10 or 12 maybe.
Will not fill lower chimney with sand yet- just to see how things will work out but think I will be able to.
Should be a good summer project
I agree with Canadian border VT that a masonry chimney is really best.

 

Sounds like a good plan, and they sell the two part T so you don’t have to do any cutting to fit a one piece in there if you’d rather go that route. It’s what I went with and am happy so far. Saved me a lot of extra work and very rigid once two parts fastened together. This pic givea you an idea of how they work. Keep us posted as the time nears!

I had some guys install my stove and I think they did a real good job. Chipped the masonry away with a hammer drill, dropped in a 2x layer ss liner and then attached the stove. Quick and easy, it was done in about 4 hours.
I don't have the T for cleaning but that's ok. It does sound nice though.

 

When i had my insert put in they ran a liner (i think it was 6" {uninsulated} ) all the way up and capped it off. The house was two years old at the time in 2001. Never had a problem with draft or creosote. Ran up one story through a steep roof.
IMO run a liner and save yourself a lot of time, money and aggravation! What if you ran the new pipe independent of the existing chimney?

 

I originally thought to do completely new. But now after discussion, I am thinking of dropping rigid stainless down existing chimney.
I guess I could cut in a new higher door and drop down rigid stainless pipe without removing all clay liner run it for a year. I could always pull up stainless pipe breakout all clay liner and re drop pipe but now insulated.
My main purpose for doing this is to clean out from ground. Chimney is in great shape.

 

Found this larger clean out door. I could install.
It could give me a better angle for feeding cleaning rods up chimney

 

An insulated liner will always out-perform a non-insulated one...but, the real reason you want insulation in most cases is that many chimneys do not have proper CTC...but, this one may be the exception since you put it up, or had it put up...it might have a better chance of being done correctly (or maybe you know for sure about the CTC?)
If it has the proper clearance, then yeah, insulation or not comes down to performance.

 

Leaving clay liner in = 1/2 inch insulation to too wide to fit.
Found this might just fit inside clay liner.
I know its not up to code without a clay liner but with the clay it might just be good fit.
1/4 inch Diameter Champion Super Wrap Insulation

 

Another option might be pre-insulated liner...it is a SS liner, wrapped in 1/2" insulation, wrapped in am external aluminum liner...tends to be just a bit smaller (7.25"?) and easier to get into a tight spot. I used that on my fireplace stove...happy with it.
Like this...
ForeverFlex Pre-Insulated 6-Inch Chimney Liner

 

Very interesting!
I found this yesterday where someone was describing his install. His was as you say stainless inside and aluminum outside.
Today doing more research found em with stainless inside and out. Did not find any reviews or installs that said they actually got it to fit in an 8x8 clay tile.
Will keep researching
Thanks

 

Could be...if so I missed that...mine is SS inner, aluminum outer...
