I've got a Devil Forge two-burner that I finished setup on yesterday. However, I'm not a fan of the propane hose being near the forge for obviously reasons. 

What would be the best way for me to insulate the line and protect it from hot air? I know for deep frying turkeys I always just wrapped some aluminum foil around the area closest to the pot, but since this is running at higher temps, I'm curious to know if someone out there has a best practice.

Metal gas line, such as small pipe, copper refrigeration tube, or stainless steel brake lines are safest--but-- a rubber or plastic hose over the lines can prove worthwhile to keep incoming fuel gas cold.
