yes it does it is a flapper that opens and closes on the outside cover
Yes
It needs 4inch duct.
If you have an existing fan/light combo it would be possible, but challenging. The fan design is clever to allow much of the installation below the ceiling. The mounting box/electrical box and fan mechanicals are separate (interesting, the answer from Delta Breez above is wrong on this). The hole for the fan is big enough that you would have a chance to install wood above the ceiling to receive the mounting screws. You could conceivably do the electrical wiring below the ceiling level, but this would be very hard. The fan connection is clever to allow you to pull the fan through the box, then connect the adapter. The problem is that for an existing fan, you won't have extra length of electrical wiring or exhaust vent to work a foot below the ceiling. The fan has many functions, so you may need to add additional switch wiring to get the best results.
No. Must keep the bathroom door open a little
1. Not sure 2. Per manual: flip the switch on, fan goes into auto mode. Flip it off and on again to turn it on full speed. 3. Not that i am aware of. If you don't want the sensor, get one without it. Model # SIG110
Air movement is typically measured in cubic feet per minute (CFM). Ventilation rates based upon eight air changes per hour are generally suggested. For most bathrooms this works out to one CFM per square foot of bathroom area. For example, a 7' x 10' bathroom would require a 70 CFM fan. My take on this is more air movement is better - especially if there is no other ventilation. 38 square feet @ 8 ft ceiling = 304 cubic feet.
Only use a 4" insulated flex hose
I don't know as both mine were installed in my bathrooms on flat ceilings & they are recessed up into the ceiling space above. I believe they are intended for bathrooms; as they pull moisture up from the shower to prevent mildew. Mine are preforming great for that purpose. I would consult your electrician.
