I am doing a basement bathroom reno and wish to install an exhaust fan in the ceiling.
Since I have had the furnace replaced and now its direct vent out the side of the house , I have an existing furnace flue in the area that is no longer in use(5 inch). Is it possible to vent the exhaust fan through this ?
As there are windows, furnace vents, gas lines at the side it is almost impossible to add a vent on the side of the house. The rise for the old furnace flue is about 16 feet and I will need to add a couple of elbows to get to the flue.
