I just got a Panasonic WisperValue ceiling fan for my bathroom.
The duct on the fan is 3" however the duct in my roof is 4".
I guess I will need a 3" to 4" adapter, I would assume these are available.
If they make them in a right angle elbow should I get it in this version or
should I get a straight 3" to 4" adapter?
The vent in the roof is almost directly above the area of the fan. Should I
run solid or flex? Or a mix, Solid going up and then flex to the roof vent?
Also how does the flexible duct stay in the roof vent? Do I press it in and
then tape it?
Help and ideas would be appreciated.
