Chimney Liner for Pellet Stove

[TPlank]

8-9 years ago I had a Harman P61 installed with the exhaust going into an existing interior chimney. The pipe comes out of the stove, up about 4' and into the chimney. Previous to the pellet stove a wood stove was in place.

I picked up 4" liner to install. I have noticed some performance issues during very cold temps and was told the liner should improve performance. My question is, how should the pellet stove be connected to the liner? I had picked up a liner kit with a T connection but I am not sure this is correct. The T connection is open on the bottom. Do I need to connect additional 4" to the bottom to help with the draft of should the pipe going from the stove to the liner be continuous with elbows, no opening out the bottom.

Thanks for the input. Greatly appreciated.

I'm set up the way you're contemplating.
I've got about 17FT of 4" ss flex liner, connected to
4" T reduced to 3" then connected to a 3" 1 foot piece
that connects to the appliance adapter that finally
connects to the stove.
At the time they had clamp/adapters to connect the
flex liner to the T which I'd guess they still make
something similar to what I've got.
The T has a cleanout on the bottom. Mine came with
a cap for the bottom. Simpson Duravent is the brand
I have.

Edit: Here are a few pics that should make it clear for you.

Oh and you'll need a cap and a way to secure it to the top
of your flue. I have a cap that clamps to an adapter
and the adapter is screwed to the top of the flue with
concrete anchoring screws. Hope the pics help you.

Thanks for the reply. I need to clarify one thing though.
Where I tie into the chimney is on the main level of my house. The chimney runs down into the basement. I is not open like a fireplace like you have pictured. The pipe goes into an approx 8" hole to the the chimney.

My T did not come with a bottom cap.

Hi there. Oh ok sorry. I thought maybe it was into a fireplace.
I don't know exactly what you'd need to do that type of install
but still the bottom of the T should be capped. The idea behind
a removable cap is so you can open it to sweep the vent.
I've seen pics on here of pellet stoves installed the way you're
describing so I'm sure someone else with know how on that
will chime in.
