This stove did not come with any directions!  I know it sounds silly but it also Is flat and has no buttons protruding out of surface, I like the stove looks pretty but I notice some of my kettles turn the stove off it just don't work on them, not sure what it is but I have one large kettle that the stove keeps shutting itself off when I return, so I think you need kettles without copper on the bottom but don't quote me.
