I was at one of the Lowes near by and noticed that they had the Pennington pellets that I read about in another post. So just out of curiosity thought I would try a couple of bags to find out if they were the dark or light ones and being that the price was @ $4.30 /bag, $179 /ton. Turned out they were the light ones. So figured I would just burn them up and set the stove to 9-9, but ran into a problem, about 2 1/2 hours later, the better half wakes me (I dosed off watching the news) and says that there is a terrible smell and her eyes were burning. I knew the smell, paint, metal smell and went down to check the stove. Well it looked like it was out, glass totally dark, so I figure ok the fire was out and that there was a bunch of smoke as to the reason why I didn't see any thing. So I pressed the Off button and gave it a couple of minutes, but the smoke didn't seem like it was clearing out... I decided to open the door a crack to peek in... Bad mistake... Flames came shooting out.... Holy Crap! The door was just covered with soot was the reason I didn't see anything. I made sure it was in Shut down mode and sat there and waited about 5 minutes and peeked in again but there still was quite a fire going. So gave it a few more minutes and checked it again, fire down a bit and then I could see that the burn pot was filled and over flowing. Just prior to setting the stove to high I emptied the ashes because I was experimenting with air flow, and I wanted to get back to the defaults. I am pretty sure that was not the fault as I returned all the settings to the previous ones. So what caused this and why didn't the stove shut down? as I am sure it was in an over heat condition. I am afraid to run this till I get a chance to call tech support, but I am half tempted just to take it back to Lowes.... lol Oh.... stove is a Summers Heat 55-SHP10 Went and got the camera and took a couple of pictures, a couple were taken about five minutes after I put the stove in shut down peeking in the door. The picture of the Closed door was taken while the fire was still going. The others showing the filled burn pot.
