    Roof Penetration for Tank Vent:

    Hello all,
    I will be running a hot water tank vent pipe through the roof.
    Can anyone reccomend the best way to make this transition while maintaining fire safety and water tightness?

    TIA,
    Molo

    This should be done with double wall b-vent which requires 1" min clearance to combustiblematerial. There are fittings available from this to provide the clearance and flash the penetration, also a cap for the top of the pipe.
