I wanted to double check the set up in my basement. I have my GF venting out of the basement window using a piece of foam that I take in/out.
However, I’d like to be able to keep the infinity fan in the window without having to remove it. My Dad got a dryer vent cap with flaps today as I was worried about the cold getting in. I also bought a blast gate off of Amazon that I will install. Tape around the foam will also be used, as well as around the fan.
This coming week is supposed to be freezing here in MA.
