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.
