looks great, Im still traumatized by the sheer size of your flippin basement
If that's a Z shape basement it must be ONE HECK OF A BIG Z!
get some newpaper, some hardwood scrapes, blocks, sticks and such... open the damper load the paper and sticks in top door, you can bunch some paper in the ashpan too if you wish, stuff some newspaper behind the removable baffle open bottom door, light the paper in the flu pipe first and close top door (wait until you start hearing the draft...it will sound like freight train)... then light paper in ash pan leave top door closed and bottom door open, add some wood when its ready and get a nice bed of red hot wood coals... once that done... sprinkle some coal across them (a shovel full).... keep that bottom door open and top closed.... wait.... add lil more coal.... wait.... add lil more and now once you know the coal caught your good to go and you can then fill her up (leave a lil' space in one of the corners to keep a slight hint of red coals exposed). close bottom door, play with adjustments and get a feel for it (remember it takes coal a long time to adjust), you will also play with damper until you learn your draft, etc. When you open the top door... do it slow!!! people sometimes forget that (reason being... you don't want the draft of the door opening to win against the draft of the flu because for that split second it allows sulfur smell into house.
OK, get some coal and have some fun!!! after the fun and the learning you can always change your MPD and do some more fancy things with reflectors and fans and all kinds of more exotic things! right now.... go have fun! you did GOOD!
