Duh, guess I had that one coming!
I saw the Yankee model and the standard and thought they were different. Silly me.
The drawings are not complete enough to really tell how it works. IMO the reason the manul has very little to offer regarding burning coal is that they had no real knowledge base in that area. Very simply my advice is don't do it, you will most certainly damage something since there appear to be no safety or control methods to prevent over firing.
Sorry not to be more positive, but since no one stepped forward with experience with this unit I thought that erring on the side of caution would be best in light of your concerns.
