Thanks for the info...any tips on keeping the temp regulated?
A layer? It needs to be filled all the way up to make heat, to the top of the firebrick and then mound it up in the middle. Don't be bashful with the coal, it may take 2 or 3, 50# bags to fill it, once going it should make plenty of heat. It sounds like you are running a very thin fire, that's why it runs away.
Once the boiler is up to temperature, it should take care of itself, you will just have to adjust the draft for the range of outside temps.
