Planning on putting a singlewall stainless liner composed of 36inch lengths inside an old chimney with a straight run from basement to top of storey and a half.
Chimney is centrally located with the access opening for the woodstove on the first floor.
After the access opening is enlarged for the placement of the T, what is used to secure the liner inside the chimney with the ensueing weight of the liner bearing down?
Does the liner need to continue on down into the basement with an opening being made into the bottom of the liner by the ash cleanout at the base of the chimney?

Rez, the chimney sweeps here use a flexible stainless one pc extendo liner to do their work. Went in easy. They do pack around it with a grout I believe. Reminds me of that metallic dryer venting you sometimes see. edit>which it isn't, in case someone less versed in construction reads this and tries to stuff that cheap dryer vent up their chimney.........

Yes, I've watched guys putting the flex in. I understand it is nice for chimneys with bends.
I already have the 36" liner sections with T 's and elbows so that's the what I'm going to run with.
Never done this before. Was wondering if anyone might have a diagram handy.
Thanks

Sweet configuration.
But I already have the brick chimney in the middle of the house.
I'll have to remove some brick at the thimble hole to get the T to fit in there. Can't see trying to put that bracket inside the chimney but sounds like a similar support is recommended. Thanks

The liner weight is actually carried from the chimney top (liner or crown) by a cone that is screwed into the liner as recommended by manufacturer. This is not the rain flashing cone which also accompanies the top finishing kit which will include a rain cap, too.
Its good that you're using the the straight pipe rather than the flex. The flex is used for "crooked" chimneys but use the straight for all others if possible. The flex liner offers twice as much "drag" resistance to flow of air or exhaust gases than does the smooth inner surface of the straight pipe.
You should have at least 8-12" of "resevoir" extension leg lower than the T to catch any creosote/soot that may fall. Without this, any that falls will start to collect in the elbow of the T and the cross sectional area for flue gas exhaust will be reduced. If you can extend it safely down to the level below, I would do it
a cone that is screwed into the liner
I didn't know that. Thanks.
Guess it's time to search the net.

Rez- The brand of liner you're using should have a clamp system that supports it from the top as noted above. You might be able to do the reverse of that at the bottom, if you have an acces hole large enough at the bottom. The system will be more effective and stay cleaner if the pipe is insulated. Back in my chimney sweep days, we used a mixture called Thermix, which was basically mortar with perlite substituted for sand. I've made my own with portland and perlite (or vermiculite). Mix it and pour it around the liner filling the void. You'll need to block the bottom so you have access to your cleanout.Birth, school, work, death.....................
I'll have to make a system.
I got the sections, T's and elbows from a guy who was moving. He had plans of putting it in a garage.
He'd bought it at an auction so who knows.
When he said $50 bucks for the whole shabang I wasn't too concerned about future installation.Thanks
