Ok...this what we did, On woodmaster stoves you can clean the upper part of the stove by pulling out the rod that opens the draft to clear the smoke, you pull it out about 18 inchs and it stops, but you trun it about 1/8 of a turn clockwise and it will pull out farther, didn't know that, you pull that back and forth and the junk fell out of there like crazey, did that a few times and its 12 degrees this morning and when i filled it up this morning the stove was at 160 degrees, look out 1 hour later and the stoves was shut down...180 degrees, hope that my problem...thanks...
