Would 1/2" OD semi soft copper work? We just popped a gas log in my brother's fireplace and he had a roll of 1/2 OD copper left over from a project we did many years back. It's a little difficult to bend due to it's age, but if you'd like I can get a piece. email me if you'd like me to send you some.
I wanted to use basic black pipe but he wanted to use what he had. Took twice as long since we had to find the right fittings and maneuver 12' of it in a tiny furnace room that backs up to his family room. But it's done and the logs are enjoyable to watch and much less mess than real wood fire is to clean up after.
