I purchased my house 2 years ago. The basement has a fireplace with a New Buck propane insert model 61TV. I'm attaching some pictures of the stove and the connection for the propane tank. I'm wondering if I can just purchase a tank and fill it so that I don't have to sign any contracts. Couple of questions: 1) With the photo of the outdoor connection, that doesn't look like a normal propane connection. Does that have to be replaced? 2) The stove itself has a very ugly liner around it as you can see. Can I buy a replacement that actually has some style instead of the flat metal surrounding?
