The MES have a cover over the chip tray and the chip tray sits over the coil, so the coil gets good protection. My question is ... if a person burning pellets removes the chip tray in attempt to get more air flow from the chip loader hole, will the coil still be protected well with the cover that is over the chip tray? One more question and that is ... what effect will this air have on the coil that is coming in directly over the coil? I've hear of people pulling the chip tray out 1", so I was wondering what would happen it the chip tray was removed entirely... ??? Has anyone tried this?
