1.Locate the vent opening on the wall. Refer to Figure 5, Page 6, to determine the opening centerline. 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 22. Combustible wall openings must be framed as shown in Figure 22.

2.Measure the wall thickness and cut the wall sleeve sections to proper length (MAXIMUM 12Ó). Assemble the sleeve with the #8 sheet metal screws supplied. Attach the firestop plate to the sleeve end with the holes. (Fig. 23) NOTE: The wall sleeve is required in combustible walls only.
3.Install the Wall Firestop/Sleeve assembly into the wall cutout and fasten the firestop to the wall cutout framing members. (Fig. 23)

For DuraVent pipe only: Install vent pipe by aligning the locking system together, sliding the pipes together and twisting clockwise.
•Install 90° elbow. Twist lock as before.
•Slide the wall plate over horizontal run before attaching the horizontal run to the elbow. Fasten wall plate to wall.
4.For CFM Vent Pipe only: If necessary, measure to determine the vertical length (X) of pipe required from the adapter pipe to the wall cutout centerline, including a 2Ó overlap at the joint. (Fig. 24) use a hacksaw or tin snips to trim the pipe as needed.
