At your vents upstairs have you checked to see what the temp loss is coming out, if it is going in at 85* what is it coming out at? 1400 cfm to me seems like a huge amount of air being moved. If you are moving to much air to fast you would need to run the stove hotter (using more coal) to maintain that comfort level up stairs. I suppose you had this plenum deal with the wood ? What temps did you run your wood stove? (stove temp)
