Started off last year burning corn, had a problem with it bouncing out of the burn pot to the extent that when doing the weekly cleaning and emptying the ash pan there was probably 2 pounds of clean unburnt corn in it. Then I read J-Takeman post on the mods he made to his Omega burn pot so I decided to try and enhance mine with out welding it (yes I can weld do it for a living ) just wanted to do something that could be removed in case of any warranty work that might need to be done. After 4 iterations this is what I think works the best. It is perforated stainless steel and seems to not interfere with the air flow, lets the ash be blown out and leaves the pellets where they burn best in the burn pot not the ash pan. Thank You J-Takeman for the idea and all the other info you so graciously add to this site.
