Agree..Some pellets produce a lot of heavy ash, especially when running on low burn all day. My P61 can't get the ash line even close to the end of the pot running those types of pellets (such as ThermaGlos or Curran's blend from a couple of years ago). Better pellets don't produce this issue (Cubex, Platinums, Okies, PTL's or FSU's run fine). I haven't run GS, so don't know what their ash is like. Additionally, the ThermaGlo's that I am running are very cold - even with a strong flame the airstream doesn't get very hot. I can magically change that just by pouring a different brand in the hopper - I can pretty much tell the instant that the other brand hits. I have resorted to mixing the TG's with other pellets to keep the ash lighter and airstream warmer.
This may or may not be the issue, just my 2 cents.
I don't subscribe to the pellet line formula..
never paid attention to it.. what ever is in my pot at whatever setting I have, that's how it works..
