Direct vent appliances can easily be located next to a wall and vented through the wall without the expense of a chimney or vent them straight up the middle of the house. They're economical.

This pipe has a 4" inner diameter, with a 6-5/8" outer diameter. Most direct vent appliances are approved to be used with DirectVent Pro.
