wall of the inlet end, which are designed to "Twist Lock"
into place upon attachment to the appliance outlet. Align
the adapter indentations with the entry slots of the appli-
ance outlet and slide together. Turn the adapter clock-

Side Wall Termination Assembly

1. Locate the vent opening on the wall. Refer to Page
7, Figure 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 24. Com-
bustible wall openings must be framed as shown in
Figure 23.
