for the second time I ve had a very bad smoke condition eminate from my stove. Both times the stove was in start up mode, both time the pellets were igniting. I got called away and place the stove in shut down mode. now the pellets continued to burn but the exaust blower didnt continue to exaust the smoke until the pellets had completely cooled/exstinguished. The smoke from the burning pellets filled the room. Heavy smoke. I thought the stove had a sensor that ran the exaust blower until the internal tempeture dropped to 90 degrees. I have two of these models and have never experienced the problem with my second stove. If anything the exaust blower on my 2nd stove runs for a long time. Im ok with that safety 1st. I P.M. Mike Holton, but figured I through it out there just the same.
