Hi there. We bought a house with a gorgeous kodiak insert, but I have no idea how to use it. I have a chimney sweep coming in next week for inspection, but I was hoping if someone could tell me how the flue works? It looks like a keyhole in the pipe leading up the chimney, but I don’t have anything to go in it.
