Is there such a thing as a telescoping pipe connection for an insert? I pulled my insert for the first time for a hearth renovation project a few weeks ago. Disconnecting the pipe was a serious pain. Re-connecting it later was even harder. Even though the lowest section of my chimney pipe is flex pipe, it is really not that flexible. I have heard guys talk about a telescoping pipe connection for a free-stander, and I was wondering whether there is anything similar for an insert that facilitates an easier connection?
