Also, if you don't have room to move it down, possibly because it may raise the CC higher than you want, you may be able to make the FB a few inches deeper and shorten the FB as Big T suggests. Which essentially does the same thing. You wanna keep the firebox Cu. In. within the SB calc specs as close as possible.Big T wrote: ↑December 10th, 2020, 6:58 pmI didn't check your dimensions, I just looked over the layout of everything. It looks like the top of the FB is higher than the BP if I'm seeing it correctly. I would drop it down a couple of inches below the BP and install a shadow plate above the throat about an inch lower than the BP. It'll really help avoid a hot spot right at the throat.
