Venting dryer thru vacant roof furnace duct
I have a vacant furnace vent. (furnace now vents another way)
My dryer vents into garage right now. Going to run new metal 4" ducting up into attic, install Fantech DBF 110 Dryer Booster Kit inline. Will also have another lint trap in the wall.
Was thinking of venting it out thru the soffit, but can I use the vacant furnace vent that goes thru the roof?
