Some of the links on this forum allow SMF, at no cost to you, to earn a small commission when you click through and make a purchase. Let me know if you have any questions about this.
If you don't already own the smoker, according to their site it's a no cost option. If you do already own it, Pops is right, just email Ben Lang and ask him about it. I'm sure he'd steer you in the right direction.
