1.Locate the vent opening on the wall. Refer to Figures 20 & 21, to determine the minimum centerline of wall opening. It may be necessary to first position the stove and measure to find the hole location. Depending on whether the wall is made of combustible materials, cut the opening to the size shown in Figure 24. Combustible wall openings must be framed as shown in Figure 24.

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. 26) 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 elbow. 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
