I have a bosca classic 500 pellet stove which shuts down on its own. I purchased this stove in 2008. This year it's happened every time i start it. Sometimes it is after 30 min, sometimes 8 hours. Last week i sat and watched the stove and it seems the auger stops dropping pellets for no reason. There is a nice fire in the firebox and it just stops. I have bypassed the low limit switch with same result, i bypassed the hopper lid switch with same results. I didnt bypass the high limit because when the stove does go out i can restart it right away. Any ideas? Does anybody have a way to contact Bosca. I had a number in Washington state but thats disconnected.
