I got this house and the fireplace inspector came out and gave it a thumbs up (propane orifice present and installed) .Hoping to get some help on hooking the rest of it up. Coming off the fireplace is 3/8" copper line without a fitting. The tank has the female-reverse thread connection (100# tank form Lowes). My understanding is I need a tank, single-stage regulator, and line to hook it up with. Is this correct? Thanks for the help.
