Well, Ive read numerous posts on here about opening and closing the ash grate on the Mansfield. I know Im going to sound totally stupid here but......I do not use the ash removal system on the Mansfield. I scoop them. I know how to open the lower ash removal door, inside that is the ash pan to remove ashes but I find nothing anywhere in my manual about a sliding ash grate to open and close to allow ashes to fall into the lower pan. Mine is obviously open as ashes were found in the pan. Where do I find this lever or mechanism?
