I just got my old Pelletmaster up and running for the first time and all is good so far. However, I get a loud squeak when the burn ring turns. I suppose I could use silicone to lubricate it, but I was wondering what others experiences were before I started experimenting with things that don't burn under 1000 degrees. I just got the pungent smell out of the house by burning off the old deposits on the inside of the stove and I don't want to start adding the smell of burned petrochemicals...
