You will need some caulking and maybe some roofing nails long enough to go through however many roofing layers you have and into the sheathing.
yes
Our thermostats are designed to operate until they reach a set temperature. If you set your desired setting 105 degrees F (recommended), the fan will operate until the temperature in your attic is 5-7 degrees below the device setting (98-100) before shutting off. If the temperature is set to lo (70-80 degrees) it may never turn off depending on the outside temperature being pulled in the attic. If the air temperature is 75-80 degrees during the summer months, the lower setting my no be achieved and the fan will continue to operate.
Yes had mine for two years now it’s fine
I think from your description that you plan to install two fans. the combined CFM would be 2500 CFM but the kicker is how much eave vent area do you have to replace the air being removed from the attic. If you don't have enough vent area to replace the air the fan is trying to remove you will be placing a burden on the fans and making them work harder and possibly wear them out sooner. They make lesser CFM fans that you may want to consider.
The screen is 1/4 mesh screening. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.
Normally, you cannot hear this turn on or run from inside your house. I have mine directly over my master bedroom and I can't hear it. Note that when I first got it, it was out of balance and was very noisy. I had to balance the fan blades to fix this.
No, this is an electric fan that runs off of typical house voltage. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.
The black wire with the cap is a hot wire going to the thermostat. It shouldn't be uncapped. There is a ground lug inside the housing for the ground wire.
