Got it done. Still need to clean out the inside of the fireplace and get a tank filled up. Wish it was all ready, tonight is an excellent night. Could sleep out there tonight if I had to.

1 3/4" Hilti Cons. 3 in each post I think should hold er down. Bought it at Costco so if it decides to blow away or bend over, we'll take advantage of their excellent return policy.
