Q: From what I understand, it is necessary for the duct outlet to be at or below the run otherwise you could have condensation roll back. From the looks of your diagram this may be an issue, as the line runs up and then down and out. No?
Asked by:  - 8/11/2014 (Submit an answer)
A: If your eave is at the same level as your ceiling, Run your exhaust tube from the fan straight up 1 foot. Then run the exhaust tube on a down angle (1/4" per foot is good) to the eve.

The immediately exhausted air from the fan does not condensate in the vertical 1 foot before it reaches the turn toward the eave.

If, because of temperature differences condensate does form in the tube, the fluid runs down toward the eave vent that you put in. Do not use an existing eave vent to vent your fan. Use this device or one like it in a rafter bay that is not occupied by an existing vent for attic ventilation. Use smooth wall duct tube/pipe, insulated, of the correct diameter for your fan.

Q: My exhaust for the bathroom is on a slanted soffit eve and will this work on the slant of the eve mounted bathroom exhaust? Thanks
Asked by:  - 9/13/2014 (Submit an answer)
A: if the slope is raked or the same slope as the roof, then its likely there is not enough room for the flex to service the vent and get to the attic. in my opinion, i think it needs all of 11-12 inches of room above the soffit level.

Q: How does the damper work?
Asked by:  - 9/24/2014 (Submit an answer)
A: I get this question a lot so i took some pictures. the round damper is hinged off center and is weighted. In my opinion, it works very well and reliably. See pictures at the item description in the store.

Good product, difficult to install.
This is a good soffit vent with a backflow prevention damper integrated into it. One thing to note is that it might not fit in the soffit of a roof with a low slope because of the extra height added by the damper. In addition, it can be difficult to snap the two pieces together to install, especially when working on a ladder. If it works in your application, a wall vent is a better option instead of a soffit vent.

Looks good, works as expected, be careful of small soffits
Bought this to add a soffit vent to my existing pipe run. If you have a small soffit area, watch the height on this. I cut it down about an inch from the top and had to flatten my corrugated alum pipe a little to get this to fit. Otherwise, works as expected and looks professional under the eaves. Works much better than just exhausting into the eaves.
