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. This precision fitting pipe safely vents flue gases, while providing incoming combustion air through the space between its inner and outer walls. DirectVent Pro has an inner wall of .020" aluminum and an outer wall of .018" galvanized steel. The components twist lock together for quick, secure, fastener-free installations. This pipe has a 4" inner diameter, with a 6 5/8" outer diameter. DirectVent Pro carries a lifetime limited warranty. Most direct vent appliances are approved to be used with DirectVent Pro.

DirectVent Pro is a complete venting system designed for use with gas direct vent stoves, heaters, and fireplaces.
