may be easier to mark both the inside and outside wall. Align holes by
drilling a hole through center of the template from the inside through to
the outside. The template can now be positioned on the outside wall
using the drilled hole as a centering point for the template.
3. A) MASONRY SIDE WALLS
Chisel an opening approximately one half inch (1.3 cm) larger
than the marked circle.
B) WOODEN SIDE WALLS
Drill a pilot hole approximately one quarter inch (0.64 cm) outside
of the marked circle. This pilot hole is used as a starting point
for a saws-all or sabre saw blade. Cut around the marked circle
staying approximately one quarter inch (0.64 cm) outside of the
line. (This will allow the vent to easily slide through the opening.
The resulting gap will be covered up by the Vent Terminal cover
plate.) Repeat this step on inside wall if necessary.
SEQUENCE OF INSTALLATIONS, FIGURE 18
Cut a length of PVC pipe about 3.5 inches (8.9 cm) longer than wall
thickness at the opening. Glue vent terminal to this section of pipe. Slide
the wall plate over the pipe to stop against the vent terminal. Place a
bead of caulking (not supplied) around the gap between the pipe and
cover plate. Apply enough to fill some of the gap between the pipe
and wall. Place some of the caulking on the back of the plate to hold it
against the wall after installation. If the vent pipe is installed up to the
wall, with a coupling on the end against the wall opening, the pipe with
the vent terminal can be prepared for gluing before inserting through
the wall. Slide the pipe through the wall and insert into the coupling on
the other side of the wall, making sure that the vent terminal ends up
pointed in the correct position, see Figure 18.
