hi everyone, looking for some help. Just bought a new house and pretty much made up my mind on the Lopi freedom insert. Specs say it will take 24" split. I'm assuming that's east to west, can anyone tell me what it can handle north to south? My old regency was a monster and very easy to load n/s, I know the Lopi is tapered but trying to get an idea if the center is going to take a split close to 18" n/s or if it's 16" and under? Any help is greatly appreciated.
