Hey all, getting ready to start building our new firebox with a Carlin 102crd, 2x6 Arch and will be reverse fired. Question are the firebox guidelines from Carlins book the same for reverse fired? From the book my firebox will 32" Deep X 16" High X 18" wide with the centerline of the burner 7.5" down from bottom of pan. Do these numbers sound correct. I'll be firing between 3.25-4.0 GPH. Thanks for any help!
