Two story with 1/2 finished basement, being heated with old steel wood burning insert into original fireplace, with front mount blower. Chimney is located on exterior west wall and would like to route air supply (if not even the blower) over to east wall, to encourage migration of heated air towards that side of home, using ..a manifold similiar to an OAK. Thinking this would also cut down on noise levels. What kind of possible problems might this cause,,and what size duct might be needed to supply say 100 cfm, depending on either drawing or pushing the flow? Thanks
John
