Look forward to hearing from you or anyone else that has an idea on this.

Doug,

I covered mine with refractory cement which is what I assume you are referrring to. I built it for long term and did this to protect it so it would last many years. If you didn't protect it, black pipe would probably burn out in 1 year or maybe last 2.
