AO Smith 100112550 3" x 4" Adjustable Concentric Termination Kit for 5.0"-10.0" Wall Thickness.

For use with Takagi direct-vent models that require a 3" intake and a 4" exhaust. This concentric termination provides the convenience of only having to make one penetration through a sidewall instead of two separate penetrations for the intake and exhaust piping. The louver termination acts as a bird screen, restricting small animals, pests, and foreign objects from entering into the vent system. This sidewall termination is available in three different sizes, to cover all ranges of wall thicknesses.
