I took out the bottom grate in my Jotul F600 and can't remember how it was in there from the factory. The picture to the right is with the flat surface up and the two tabs(by tabs I'm refering to the two small rectangular bumps in the picture on the right at the very far left and far right bottom of grate) towards the glass or I could turn it so the tabs would be at the back of the stove. The picture to the left is with the beveled surface up and the tabs at the back of the stove or I could turn it and have the tabs towards the glass. You can't see the tabs because they are beneath the grate It probably does not make a difference but I would like to put it back the way it should be.
