Direct-vent concentric/coaxial termination
This part is used to terminate direct-vent (sealed combustion) systems with indoor tankless water heaters and high condensing boilers. This concentric design lets you make only one hole through a sidewall instead of two, one for the intake and another for the exhaust pipe. It includes a bird screen to prevent small animals and insects from entering into the vent system. It is available in two different variable sizes for a wide range of wall thicknesses.
