I just purchased my pellet insert and looking and reading at everything. I cleaned the ash pan and vaccumed everything i could see but i only burned 4 bags so it was not that dirty I am reading posts and don’t have a problem removing the plates but am concerned with brushing the vents because of the heat probe I read that you should remove the probe from the back before you brush it. or should you only do that after the 1 ton mark and can you brush it with the probe still attached thanks.
