    from Enfield, CT asked:
    October 5, 2016
    What is the actual outside diameter of a 4-inch diameter b-vent pipe? Does 4" vent pipe refer to the inside diameter? I am fitting a pipe through a concentric vent box that has an inside diameter of 4.75 inches and am concerned that the pipe will have too much clearance when installed.
    1 Answers
    The 4" diameter is referring to the inside diameter of the pipe. Additionally, the outside diameter of the Duravent Type B system is 5/8" greater than the inner diameter.
