I have a 2nd floor gutted batheroom,ready for remodel. I need to install the vent fan, but the joist run to the side of the house where it will be a real pain to work on the outside on a ladder. There is an old, unused chimney stack running through the bathroom and someone had at one time run a vent from a gas space heater into the chimney stack. So I have this great vent opening just waiting for me to take a shortcut. My question is.... can I run my bathroom vent into this unused chimney stack? What would be the possible downside to attaching my bathroom vent to this opening? Like I said, the chimney is not used by anything anymore.
