I always wondered why that would be a problem as there is tons of fresh air in the basement and the partition in the basement does not even go to the top of basement letting even more air into there,I have closed my stairs off on my 2012 and 2015 all year round and for sure the Winter where lots of cold air comes in with no ill effects

I just cut black poster board to fit and screwed the covers back on. Add it in the spring when I put the register vents that cloose in for the summer and take them back out when I put the open register vents back in in the fall. just the thought of blocking the return air and running the furnace gets the furnace manufacturer reps all excited at the Rally.
