In some cases it is more economical to upgrade to a 90 efficient furnace than to add all of the equipment and b vent needed to side wall vent an 80 efficient furnace.
Sidewall power vents also rate highly in efficiency and safety.
Also known as the induced draft fan this one has a fan that is located on the end of the pipe.
