Continue to add pipe sections through theflashing until the height of the vent cap meets the minimum heightrequirements specified in local codes. Note that for steep roofpitches, the vertical height must be increased. A poor draft, ordown drafting can result from high wind conditions near big treesor adjoining roof lines, in these cases, increasing the vent heightmay solve the problem.Pipe LengthFlashingRigid Pipe AdaptorHigh wind cap(not supplied)(Dura Vent Only)Roof Pitch Minimum Flue HeightMetersflat to 7/12 0.61over 7/12 to 8/12 0.61over 8/12 to 9/12 0.61over 9/12 to 10/12 0.76over 10/12 to 11/12 0.99over 11/12 to 12/12 1.22over 12/12 to 14/12 1.52over 14/12 to 16/12 1.83over 16/12 to 18/12 2.13over 18/12 to 20/12 2.29over 20/12 to 21/12 2.44
