This was in the house i am renting!! when i took the flue pipe off the furnace to get to the coil, i noticed it was loose in the attic, crawled in this tiny, and i mean very small attic, and found this!!!!!! Thats seriously a fire hazzard!! and we went a winter in this house and didnt even know, I have a little girl in the house too!!! that made my heart drop when i saw it, Thank you God for protecting my family!
