Hi all. Just bought a Pacific Energy 27 off cl. Im trying to hook it up to a 6 Inch chimney that was capped off when we bought the house. They took that stove with them. I have the hearth pad in place and stove on it. Went out today and bought a telescoping pipe. Fits the chimney fine, but at the stove it won't fit. Seems to be the exact same size. It wont slip in stove. Is there an adapter I need? Thanks in advance and Yes, I have this winters wood all css and am working on next years!
