Hi everyone, I have a Harman XXV stove, wired to a Lennox thermostat. I don't remember the specific model thermostat, but it is millivolt, and this is the 2nd year of using it, so it is hooked up correctly.. I burnt through a ton of Big Heat pellets this year, without any problems.. I just ran out of them, and the only thing available in the area were Ozark Hardwood pelllets from Tractor Supply. As soon as my stove switched to the Ozark pellets, It started giving me problems. It was having trouble igniting.. it actually timed out (36 mins) and was giving me a 5 blink status. I reset the stove, and tried again. This time it did light, started blowing some heat until the stat was satisfied, and shut down. I have it on auto light mode, so it should shut down and re ignite if the stat calls for heat.. When the stat called for heat, I watched it light for a moment, but ended up timing out again. I reset it, and this time it did light up and make some heat, so I switched it to manual, so that the fire wouldn't go out, and I went to bed. When I woke up, the stove was off, and hardly used any pellets at all so it must have went out shortly after I went to bed. This time the burn pot was pretty much empty, so I reset the stove and watched it, the auger wasn't turning.. I noticed that these pellets are sometimes 2 inches or more long, which is not what my stove is used to.. and they are also very dark in color compared to other brands I've burnt. Could these pellets be my issue? I'm going to buy a few bags of something else to see what happens...
