If that is the same firebox as the summit, which it appears to be. It's meant to be loaded N/S(straight in) for best performance. It'll make it easier to stuff it right full with no worries of wood rolling onto the glass.
Looks great though!
I've never really compared the FP30 with the Summit fireboxes, but I've heard that they are the same .
I loaded the previous 2 splits N/S but decided to change it up and go E/W this time.
I've not yet had it loaded up full because we haven't had the cold temps to warrant it. I'm hoping to fill 'er up and see how long she'll burn.
