im having my chimney lined with a 4 inch ss liner. There will be a t at the bottom that goes into the house. The T is smooth ss. My question is how on earth do I connect the hundreds of dollars of pellet vent pro pipe that is meant to insert and twist lock onto a smoothe, round ss pipe. I'm at a complete loss. I asked around for an installer but they refuse to install hardware store "junk" they say. Please help. A video or photos would be awesome. Thanks
