It’s 21’ tall. I think my main problem is I’m used to loading on a full hot bed of coals for e/w loading and with n/s I’ve found it takes off way faster than I’m used to. So I’ll either need to dial it back faster or just burn the coals down more.(Though this might deserve its own thread) How tall is your chimney?
Sometimes it can help better control the stove in such cases if you dial down the air sooner upon a reload.
