Hello forum, so I am finally installing my liner and have a question about the T where it comes through the chimney into the house to the stove. The hole is quite large compared to the 6 inch pipe. The previous was a 8 with a 7 adapter. Do I mortar the single wall pipe there. The metal plate covers it, just seems like I need to do something there. Thanks. I just laid the pipe in there so you can get an idea of the size.
