Are these supposed to be installed through the ceiling drywall into the joist or just directly into the joist? The instructions dont specifically mention anything. Some pictures show the unit as being screwed through the ceiling drywall into the joist, and others show it being screwed directly into the joist. Any advice here? I have the FV-10VSL3 and I'm just not sure.
It has the oval duct since it's slim, and i found it hard to get access to the bottom of the exhaust because it was almost flush to the top of the ceiling drywall. I couldnt even fit a clamp over it, or tape. This leads me to believe that i either needed to screw it in directly to the joist and not through the drywall, or that i should have attached the duct first.
Thanks!
