Use components listed under "Approved Vent System
simpson
Components" under 'Basic Straight through-the-Wall
Installation' for an installation where the heater is parallel to straight up
the wall and the vent system extends straight back through 8/07
that wall.
1. Locate the vent opening on the wall. Refer to Figures 3.20
& 3.21 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 3.20. Combustible wall openings
must be framed as shown in Figure 3.20.
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 3.22. NOTE: The zero clearance sleeve
is required in combustible walls only.
