Just purchase this home with this unique Stone / Metal backing with a vent. I am not sure why they cut an opening in the metal sheet. Started a fire for the first time and smoke was coming from the vents. I would like to know if I have to wield a new sheet of steel to cover the opening. photos are front and back vents.
