    Default Heat shield

    Is this intended to be a permanent part of a heat shield or packing material. This is an American Standard 90 percent gas furnace.

    Appears that the shipping/packaging material was never removed.

    It's a noxious smoke generation system, for random testing of the smoke alarms in the home.

    They would take it out but it burned their fingers.

    Thought it might be a good place to thaw out some steaks.

    Do not think of knocking out another person's brains because he differs in opinion from you. It would be as rational to knock yourself on the head because you differ from yourself ten years ago.

    I agree with the rattle theory. No way that got there by accident.

    Had a similar situation on a 80 furnace in a mobile home. They used egg crate material. Only found 1 scorch mark on the three areas they stuffed it.

    I cant tell by the photo if it is a paper packing (egg crate) type material or if it might be a material that is similar to rock-wool insulation, like some of the covers being used over non-IC rated recessed lights. I'm just curious enough that I would break off a piece and and try to burn it. I would agree that it is probably been put there as a vibration dampener.

    I would say it was some packing material. Some older furnaces would have similar heat shields, but with this one being a 90% you just wouldn't have that much heat to worry about.
