We installed our stainless liner and tee. My dad was inside and attached the tee to the pipe with the clamp. He came back outside before we attached the liner at the chase cover and found out the tee slopes down, into the chimney, probably an inch or 2 in 24". That was after we trimmed the excess pipe above the chase cover. We tried unscrewing the liner from the chase cover and pulling the liner up, there's nothing to grab on to at the top without taking the chase cover off, and pushing it from below doesn't help. It fits pretty snug in the collar of the chase cover. Before I go on the roof again and go through pulling the whole chase cover off, is it worth worrying about?

Smoke does not go downhill willingly. The tee connector should be pitched uphill toward the tee by at least 1/4" per foot.
 
Can you get channel locks to grip on it? Another thing you can do is slide a board in under the T and use that to push directly from the bottom.

I see a lot of rear vent stoves with 12 or sometimes 18 inches straight pipe until the T that appear to join at 90 degrees. Is there a pitch there that I can't see? Or people just run it like that for simplicity
 
It's hard to see the slope in 18" in photos, but it should be there. At the very least it should be level.
