Can this be used in a whole house fan installation?
Asked by: Jeff
Yes, you sure use it with a whole house fan. You would need to put a few more vents on the cooler side. You can even put two vents on the hot side of the house, where the whole house fan is installed. They have many different vents that will look nice from the outside.

What is the required flow for the vent to open? My fan is rated in CFM. Can I add a bug screen during the installation? Are the instructions online somewhere? Model No. Opening Dimensions Overall Dimensions SGM20 16 1/2" x 16 1/2" 19 1/4" x 19 1/4"
Asked by: tucsondon
yes you can add a bug screen but I think it will be hard with the way it opens, I used the gable attic fan they sell at home depot and it works so good

It seems to open easily with a breeze. Any suggestions? The online documentation says it only opens when the fan is on.

Asked by: RAS
Put a small magnet or two on the bolts(will not stick anywhere else) holding the shutters on. On the outside of the vent.I used the two small magnets from the plastic clips.like you use on potato chip bag.

We have a "dutch colonial revival" house built in 1905 which has a "barn roof". Because of the barn roof, the entire 2nd story is enclosed under the roof and therefore the heat absorbing roof shingles. On days with lots of sun, it was usually 20+ degrees hotter upstairs compared to downstairs. We noticed a BIG difference after installing the shutter along with a Master Flow 1450 CFM Power Gable Mount Attic Fan. I'll have to wait to compare electric bills with last year to see whether we will save any money on our electric bill using the fan plus air conditioner vs. just the air conditioner last year.

The mounting holes are elongated, perhaps 3/4" long. No fastener is going to cover the entirety of the hole which means that rain is going to enter around your fastener. Because the metal is about 1/4" from the wall behind it, filling with caulk isn't going to work. Kinda disappointing that the manufacturer's one-size-fits-all attachment provision overlooks a real-world problem. Otherwise, the shutter is quite nice and does what it's supposed to do. Too bad it doesn't include a screen - another real-world consideration.

I started to install solar attic fans and the company said that you should not use a louver shutter for the opening for exhaust. I chose this since it is aluminum I saw it in the store before I bought it. it has worked fine for the application.
