1600 m clayton help!

I am trying to burn anthracite stove coal in my 1600 m. i have burned wood for years with great success. i have read alot of the posts about this subject and would like to know if anyone can help.
i get a very good coal fire goingand slowly load it up. i get 6 inch blue flames for hours sometimes 8 hours. i wake every morning to find that i have a full bed of unburned coal . when it is running good, i have nice draft.06 . some how i am losing draft...... origionally i thought that i needed to shake it down more....i am also wondering if shaking it down is packing the coals together . how much should u shake this down? anyone figure this machine out yet?
notes:
1600 sq ft farm house
newer masonary chimney 2-1/2 STORIES
drafty/loose basement
increadible draft when burning wood

Does your fire box have a design like this, with the V shape and two grates in line with each other?? Disregard the water coils, I added them recently.

Do a search on your stove type or the US Stove company or Hot Blast. I think they are all the same. You need to have a deep bed to sustain a coal fire. It is not like wood and readily burns what is nest to it. The draft is tricky, it might be to high or to low. Depends an how plugged the grates are and how well air is flowing up threw the coal. It MUST come up threw the coal. To much draft would just be wasting heat up the chimney so I would guess it is not coming up threw readily. There are people using your stove, so do the search and you will find your answers. Also, the type of coal is real important. I would guess you need nut or stove.
