I found a major lack of insulation around my fireplace (model bgd33n). How do i fix this?
Here are some pictures.
1 picture: when i open the front window screen there is an exhaust pipe to outside, i assume that this is normal, that cold air flows through from outside, as it is an exhaust
2 picture: notice the natural gas pipe, the whole area where that pipe is coming from is pretty cold, i wouldnt even call it a draft, more like a mini wind tunnel that's damn cold.
How do i fix it.
