Does the furnace have an fan on the exhaust? where will the 2 units connect? a masonry chimney? a B-vent chimney? is the chimney entire indoors (until it goes through the roof) or is it outdoors? how long the the lateral vent before it ties into the chimney? how tall is the chimney? what type of pipe will you use?
