I got my Pacific Energy Super insert today. I've got a brand new chimney liner installed, just need to trim off the bottom foot or so, lift the insert into the hearth and attach the liner. My question is about that connection. The liner came with an appliance connector that slides into the slot on top of the stove and a screw clamp that attaches the liner to the clamp. Do I need some kind of sealant around the appliance connector where it connects to the stove? Or does it just sit in there snugly? Seems like this should be an airtight connection to prevent carbon monoxide from entering the home.
Here are some pics of the connection I'm talking about:
