Side Wall Termination Assembly

1.Locate the vent opening on the wall. Refer to Figures 27 & 28, 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 31. Combustible wall openings must be framed as shown in Figure 31.

2.Measure the wall thickness and cut the wall sleeve sections to proper length (MAXIMUM 12”). Assemble the sleeve with the #8 sheet metal screws supplied. Attach the firestop plate to the sleeve end with the holes. (Fig. 32) 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. 32)

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. 33) 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 the elbow to the outside wall face, about 2” or the distance required if installing a second 90° elbow. (Fig. 34)

8.Slip the wall plate and trim collar over the interior end of the horizontal pipe and install into the wall sleeve. Seal the joint inside the wall plate if needed to keep cold air from being drawn into the home.

9.Connect the horizontal pipe to the elbow. Fasten the wall plate to the pipe with three sheet metal screws. Slide the trim collar up against the wall plate to cover the screws. (Fig. 35)

10.Install the vent terminal. (Fig. 36) Guide the inner and outer vent termination collars into the adjacent pipes. Double check that the vent pipes overlap the collars by 2”. Fasten the termination to the wall with the screws provided, and caulk the joint with weath- erproof sealant.

11.Install Charcoal Gray Pipe Rings (#7FSDRG) or Polished Brass Pipe Rings (#7FSDRP) at pipe joints, if desired.
