My thermostat has a white wire and a black wire for power supply hook up, but what are the two wires coming out of the thermostat that are tied together with a wire nut? One is black and the other is white with a black stripe. Should I just tuck those back into the thermostat box?
Asked by: Neil
Yes, just tuck those back into the box. That is the connection between the thermostat and the fan motor. If you want to get fancy, you can use a 3 conductor wire and a switch to connect in with that pigtail to bypass the thermostat. That way, if the switch is off, the fan come on as the thermostat requires, but if the switch is on then the fan runs continuously. note, there is also a green screw in the thermostat box for your ground wire connection.

Why does it have to be located 24" below the ridge. I would like to install in a storage shed closer to the ridge.
Asked by: Arrie
In most cases it gives protection from wind driven rain. This fan helps cool attics up to 1,600 sq. ft. in size and requires 480 Sq. Inches of NFA intake. I would not recommend this for a storage shed. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.

1000 CFM Brown Power Roof Mount Attic Fan is rated 4.4 out of 5 by 54.

My installer wanted black but this one was bare metal that he said would rust so I painted it black and no thermostat/ humidstat so I used my old one. All in all, a mediocre experience.

I took the motor and fan assembly out of the cowl unit to replace an existing Master Flow attic fan unit that froze up. It was better than hiring a roofer AND an electrician to replace the entire fan. It was also cheaper to buy this whole unit than to buy the motor and fan separately. I suspect that the metal housing on this unit will eventually rust over which is quite ugly. I do not know of Home Depot sells Master flow units that are rust proof. BTW. I was able to put the unused metal housing in our recycling bin. As far as this unit working well, the motor and fan fit into my existing housing perfectly and is running perfectly.

Bottom Line: Good product, easy to install, but it didn't help my attic temperature. I installed this on my roof without much difficulty and it works well. It pushes a lot of air out of the attic and it is quiet. I can't even tell when it's on. I attached it to an extension cord (by cutting off the female end) and plugging it into an outlet in the garage. This gives me a virtual kill switch when I want to turn it off, like in the fall when I want to keep the heat in the attic. Biggest downside: The actual temperature in my attic at the rafters above my ceiling did not change one degree whether the fan is on or off (it stayed 110 degrees). I think the problem is that it is pulling the majority of the outside air from my air vents (near the ridge) and then pushing it out. In essence, most of the cooler air coming in is being vented outside by the fan. I need more air disturbance in the attic and more soffit vents. Before you buy this, make sure you have plenty of soffit vents, otherwise I don't believe it will do you much good. Were I to do this again, I would just put in a couple of vents and better insulate my attic. Of note: it used 145 Watts when in operation according to my meter.
