I'm sure I was being a little cautious not wanting to run everyone out of the house by "over-heating/firing" the stove (still have my BIT hat on...). So, I didn't fill up the firebox with coal. I'm probably 3" or more from the top of the bricks now. Sounds like I completely blew "anthracite 101". As I understand it, you should pretty much fill up the firebox. Adjust your temp with primary air control. The depth of the coal is really more about how often you need to fill the fire pot...not necessarily as much about the stove temp... Im guessing I get an "F" or at best a "D-" on day 1of burning anthracite.
After I added the 30lbs of ant a couple of hours ago it has been back up to 300+ .
Currently 307 above the door, 152 in the pipe and -04 on the mano. The house is 74*.
Next tending I'll get the depth up to the top of the bricks.
