4.If necessary, measure to determine the vertical length (X) of pipe required from the first (transition) elbow to the wall cutout centerline, including a 2” overlap at the joint. (Fig. 25) Use a hacksaw or tin snips to trim the pipe as needed.

5.Install first the inner then the outer straight pipe section(s), trimmed end down, to the point of the el- bow. Drill 3 holes through each joint and fasten with sheet metal screws.

6.Install the elbow using 3 sheet metal screws at each joint.

7.Measure, and cut if necessary, the appropriate length of pipe section needed to make the connec- tion through the wall. Include a 2” overlap; i.e. from the elbow to the outside wall face, about 2” or the distance required if installing a second 90° elbow. (Fig. 26)
