Hello, I recently bought and began using this stove ,with wood pellets. When I ran it in auto with the heat range at setting # 3, The air at the stove blower vent was about 200 degrees which I was happy with, but the stove would shut down after about 4 hours with the err2 message on the display. so Iv'e been running it on the #1 heat range setting and it seems to work fine but my temp coming out has dropped to 100 degrees. So hopefully someone out" there" Has TWEEKED a good combo of heat , draft and vent settings that might keep My stove running and give Me more heat ! Thanks, CE
