To anyone who has done a 5.5" liner with a T at the bottom, what size is the connector pipe that comes out of the T? Is it a standard pipe size (6"?) to connect to your stove pipe, or do you need some type of adapter? Also does anyone see me having an issue getting a 5.5" with the wrapped insulation down a tile lined, straight chimney about 20'? I'm sure insulated 6" wont go, and just wanted to make sure the 5.5" will fit before I order.
