I am concerned about the amount of flying embers/ unburned pellets flying about my stove. When I called the manufacturer, they told me that when new pellets drop in, it should disturb the lighter embers/ash, and bounce them out of the pot. But how much is too much? I've burned wood my absolute entire life. And when my father said he was switching to pellet, 4 years ago, of course I was skeptical. But it truly amazed me. Pour them in, and clean it out. The manual that comes with my stove sucks. What settings, upper and lower lbs/hr, draft fan rpm, and heat range, is every one running their USSC/ashley/king 5500 at? Please only respond if you have this brand. I have a thermostat hooked up as well. Oh. And when i spoke with manufacturer, they did with a thermostat, you should leave it on HR-3. They said it allows the stove to range better on this setting. Thank you.
