I've been running my stove (I'm new to it, just moved into a new house) since the fall. I've burned about 2 tons of pellets and the stove ran great. A few weeks back after cleaning the burn pot, I noticed a small stress fracture in the feed weldament. Well.. long story short it had to be replaced. Luckily it was under warranty. The first time the repair tech came, he was rushed, hadn't seen the how-to video from Harman and didn't properly seal everything. There was a lot of smoke... He just came back and we re-did it together, making sure to seal everything properly. Now we had to remove the insulated heat shield twice to make the repairs. Now, today I ran the stove pretty hard. It's about 30 degrees outside and I had it set to 75 (room temp) the stove was chugging along for about 7 hours. I noticed the top of the stove on the left side was very hot. I could touch it but it was uncomfortably hot. I seem to remember that only the top front of the stove was hot before the repair. Also, the stove top on the right side is nowhere near as hot right now. Strange.. I opened the hopper and the left side (front corner) is very hot.. I can touch it, even hold my hand there for about 2-5 seconds (depending where I'm touching) but it's much hotter than I ever remember the inside of the hopper being before. Again the right side is just warm, like I remember the entire thing being before the repair.. I believe that we re-installed the insulation correctly. The insulation did seem rather fragile though. All the sheet metal screws were inserted and tightened. Could the stove not be level? We did have to move it around on an uneven hearth so maybe it's not perfectly level? Not sure if that could have that dramatic effect? Wondering if the insulation became compressed on that side somehow? Anyone else notice the inside walls of the hopper get hot on the XXV?
