Because this design is to blow out HOT air thru the front grill. It is rare for any of the round ducts to be used when this type model is used. BUT, when you do connect the 4 inch or 1.5 inch flexible ducts, that is to just get a small amount of heat to the connected hoses and areas. I have never had this complaint, but I have never seen the duct hoses utilized. You would have to block off the the detachable front grill where the hot air comes out to force the air thru the duct hoses. Doug
