Hello everyone! Newbie here - just got my first pellet stove (Lopi Yankee). I already looked through many of the posts on this board and found a lot of useful information. Thanks! I still have one question though - how high should the flame be during routine operation? At the moment, I'm running it on the second lowest setting (of six total) and the flame is anywhere from 1-2 inches to 10-12 inches (varies a bit over time and the restrictor setting, I'm trying to keep it in the middle ). What is the "optimum" height for a flame? Should this be higher when the stove is running on higher levels? Should the flames ever reach the tubes at the top? Should it really look like the stove on Lopi's website (http://www.lopistoves.com/productuide/detail.aspx?id=201) when in operation???
