We have a fireplace that we want to use for the occasional cozy fire. We're not ready to spend thousands on an insert, so we just bought new glass doors at Home Depot to replace the broken, ugly ones that were there. Dh is opening up the package (that has a pic of a nice fire behind the glass doors), and in big red letters at the top of the instruction page it says "NEVER close doors while fire is burning." 
Did we just get cheapo doors, or are you never supposed to close the doors while your fire is burning?
