I finally went to the HVAC parts place and bought a duct fan the size of the old duct so that I can blow air down without the little fan. Everything seems to be no bigger a hassle than usual except that the directions for the new duct fan say repeatedly it's only for horizontal installation and I want it to be vertical, straight through the vent.
Anybody know that this is okay, or that it won't be? I guess I'm mostly worried about somehow the motor catching fire or something, though I can't think how. Can someone dissuade or reassure me?
