1. Locate the vent opening on the wall. Refer to Figures 20
& 21 to determine the top of 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 21. Combustible wall openings must be
framed as shown in Figure 21.
2. Measure the wall thickness and cut the zero clearance
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. (Figure 22) NOTE: The zero clearance sleeve
is required in combustible walls only.
