Double-wall flue pipe requires a minimum 1' clearance to combustibles. If your system will have a b-vent (double-wall) flue, it should be cut in and installed now, so the space necessary below does not get covered by ductwork. Plaster stop is nailed around the return grille locations so the sheetrockers will provide the necessary openings. This is especially beneficial during cooling season. It is desirable to have a return at the high point of your ceiling to keep the hot air from collecting up high. Our example home will have 3 or 4 good sized returns. Be extremely careful to NOT cut into the floor joists below. This will help keep down the sound of air velocity at the grille.

If your wall is 3 1/2' deep, make your grille 6' or 8' tall. Oversize the grille size in comparison to the hole down through the wall cavity. It is amazing how much this will help the airflow. The returns cut straight down through the wall cavities. If need be, drive a nail and go downstairs to verify location before cutting in. Make sure your floor registers are positioned between the floor joists, not spanning over them. The holes should be cut approximately 1/4' large to allow some slack for the future registers. Supplies should be about 8' from the walls to allow clearance for curtains. Go through every room on this main floor and mark out the supply register locations in the floor and the return locations in the walls.
