Diversitech 3 inch connection horizontal or vertical concentric vent exclude-from-data-feed NRC711 OD heats water onConcentric Vents Concentric vents make it easier to have a two pipe installation for high efficiency furnaces. These vents simplify installation and only require one hole through the wall or roof where the pipes terminate. Without using these vents, the installation would require cutting two holes through the home, one for each pipe. These vents save time and money by reducing the amount of work required. Available in 2in, 3in or 4in intake vent sizes.
