https://www.hearth.com/econtent/index.php/forums/viewthread/681/ Merry Christmas You just received the Penguin award for absolutely the most dangerous install witnessed on the new forum. There are so many code violations, I do not know where to start. I would store your tools out in the shed, as you would hate to loose them since you will need them soon to do the fire restoration job. Do you have any idea how combustible the paper faced insulation is ? It has tar composition. I know you were testing it out upstairs then pushing as hot as you can over 500 degrees???? Be careful that is one dangerous setup and you are living on borrowed time.
