My Lopi was burning erraticly & after a thorough cleaning, or what i thought was thorough , it was still burning s@#$$y then i rememered a ton or so ago, i let the pellets run down in the hopper. Got in there with my little shopvac & fingers & pulled & vacumed out a boatload of fines. Long story shortned, world of difference in the burn. The erratic burning had been responsible for a major buildup in my outside exhaust. Just thought i'd throw that out there. Muss
