After good discussions with tech support it appears that my lazy flame an unused pellet issue only happens when I run the stove at reasonably high heat settings. When I go to a five or higher on the heat range I have the issue. I have run the stove for the last few days keeping it at a 4 or less and have had no issues. The heat setting seems low yet I have the Mode at C and have a pellet brand that based on how they were produced feed faster than most. The low pellet feed option has no impact after a certain heat range so this option made no difference. It could be an anomaly with the stove like the configuration yet I don't think so as the stove and vent were installed based on the manufacturers standards and I keep the stove clean as well as yearly maintenance as recommended by the stove vendor. This issue is part of the FAQ on the problem on the manufacturer's web site so it is a somewhat common issue. I also noticed I was using more pellets than the suggested 16 - 24 hours for each 40 lb bag.
