## Questions & Answers

**Q: Can this be installed horizontally (laying flat?) Will the damper operate this way if connected to a bath exhaust fan?**
A: I don't think the exhaust fan would keep this open. They use  more of a low pressure and high air volume this requires more pressure.

**Q: My dryer has condensation on the door when not in use. Will this help keep humidity outside?**
A: Possibly. It is keeping the humidity and condensation away from my dryer. However I am not using it to go outside. It is made well and should prevent air from outside trying to come in. 
I think they make flaps specifically for that though.  Good luck. 
Ours is working out great!!

**Q: will 4 inch flexible aluminum dryer vent pipe fit OVER this ?**
A: Yes, 4 inch flexible aluminum dryer vent pipe will fit OVER this.  It's how I installed it for my dryer.

**Q: IS one side male and the other female?**
A: both sides are male.
