How can i mend my smeg oven door?

i took the outermost pane of glass off of my smeg oven in order to clean it and now i can't put it back. There is some kind of fan system? between the outpane and inner pane and i don't have a clue how to reassemble it...its just a strip of metal and what looks like 4 plastic hinges? Any idea where i can find a picture of what it should look like its not in the instructions?
