Flat,
I'm sure to that the efficiency will go out the window when I start to push it. Some things I found out were I dont need to run the over fire air dampers full open, the grate air doesnt need to be opened up much until the end of the burn time, now this stuff might change once I load the fire box up. I really need to dial in my firing times and air settings but so far things look promising. Heres a link to a short video I took just after firing.
