I used to have a massive propane tank hooked up to my fireplace, but with 2 small kids, we really didn't use it too much and it wasn't cost effective to keep it. Now that the company has removed their tank, I'm left with a rubber tube on the outside of the house simply terminated with tape. I'd like to know what I would have to buy/do to attach it to a 20lb propane tank. We really don't use the fireplace much and I don't mind if I run out of propane in the middle of the winter. thanks!
