    Rated 4 out of 5 by bath fan this fan was put in by a plumber. cost was $100 labor + the fan. It works great! April 26, 2016
    Rated 5 out of 5 by Very goood. Was the highest rated for performance and quietness. One downside. Came with a 6" wide vent and the vent in my bathroom is only 3" so took a lot of adjustments. Wish they had made that clear on the package. Another downside, it came with two hard to find light bulbs. (With two metal poles sticking out 1/2". Will they be around in five years? I've never encountered them anywhere else. This worries me. April 26, 2016
    Rated 5 out of 5 by Great fan and an easy install. I installed mine from the attic to replace a faulty cheaper model. Probably took me 45 mins to put it in. Additionally I had to vent out of the side of the house so all in all the entire job took about 3 hours. After finishing the job I took one of the hottest showers I've ever taken. I came out looking like a lobster and the room had no humidity. I did not get the lighted model. Fan only. I gave this model an average feature set rating as there is no humidity sensor, night light or anything fancy on it. It's a fan... A powerful one at that. I'm excited to compare this to a fan for my downstairs bathroom reno I just ordered. It's a Panasonic recessed light fan. It's considerably more expensive so I'm curious to see the difference in quality compared with this lower end broan. January 1, 2016
    Rated 4 out of 5 by Good Solid Product The product is quiet and it does pull a bit of air. I would recommend it. July 16, 2015
    Rated 5 out of 5 by Bathroom exhaust fan - works well. Went in easy! Purchased new QT140 E Broan bathroom exhaust fan when we were doing a complete bathroom remodel project. Looks fine and the fan installed very easily. The sound is what we expected - much more quieter than previous smaller original fan. February 6, 2015
    Rated 5 out of 5 by amazing fan I had a professional installation to start with. They installed one that was too small! I went to the Broan site and put in the dimensions of my room and wah-lah. I discovered I should have had a more powerful unit for my large bathroom. I was able to take the old one out and put the new one in in LESS THAN AN HOUR! I helped my nephew install the other one in his house. February 6, 2015
    Rated 5 out of 5 by Great Fan! This fan does exactly what we wanted. It keeps the mirror fog free during showers & the bathroom is cooler in the summer. February 6, 2015
    Rated 5 out of 5 by This fan is super quite and moves alot of air. This fan is super quite and moves alot of air. Would recomend. February 6, 2015

    1) If my roof cap has a built-in damper, do I need the flap in the Duct Connector?

    2) Assuming that I do need the flap, then more help in installing the flap would be nice. Here is where I am confused:

    Looking through the 6 inch round connector as it goes into the rectangular shape to attach to the fan, the top of the rectangle has a "foam strip" glued to it. If I insert the flap with its top in front of the foam, then the flap will be restricted from fully opening, but the flap will close completely (see picture "flap top in front ..."). If I insert the flap with its top behind the foam, then the flap won't close, but can open fully (see picture "flap top behind..."). Please let me know which is the correct installation.

    It seems to me that the "foam strip" should be positioned more towards the front, so that the top of the flap can be behind it, which would allow the flap to both fully open and close.

    There are no details given on this part of the installation. I feel that this is important information, because the tabs on the flap seem weak and will only tolerate so many attempts at installing it correctly. Also, I believe that I have the orientation of both parts correct, but it would be nice to have confirmation.

    Answer: 
    Thank you for your question on the model QT140E exhaust fan. If you have a damper on the outside roof or wall cap, you wouldn’t need to have a damper on the unit itself, but it would be helpful especially in the winter. When the damper duct assembly is installed on the unit housing the fan will blow the bottom of the damper open, out away from the fan. The bottom of the damper will have a bend in it and when closed will bend back towards the fan. If you need further assistance please contact our Technical Service Department at 800-637-1453.

    Answer: 
    The question is great and the photos are helpful. I am having the same issue and need some clarity.

    Unfortunately, I am not sure if the answer given by the manufacturer was foam in front or foam behind as you describe it. The bending answer they gave was confusing because I don't want a restriction but it would be nice to have a nice seal in the winter.

    Can you guys answer in the context that the question was asked? Flap top in front of the foam or flap top behind the foam???

    Answer: 
    Thank you for your question on the model QT140E exhaust fan. The QT140E requires a six inch, preferably rigid duct, but a six inch to four inch reducer is included for the possibility to connect to four inch duct. Using four inch duct work will reduce the rated CFM from 140 to 130. You cannot use three inch duct. Using three inch duct will greatly reduce the CFM, cause the motor to run harder than it should, reduce the life of the motor and void the warranty. Please contact the Technical Service Department at 800-637-1453 for further assistance.

    Answer: 
    Thank you for your question on the model QT140E exhaust fan. If you have access from an attic or crawl space above, the best way is to place the QT140E face down on the attic side of the ceiling and trace around it. If you need to do this from the bathroom side, you will actually need to cut out more of the ceiling than would normally be needed and repair the ceiling after the installation is done.
