Align holes by drilling a hole through center of the te mplate
from the inside through to the outside. The temp late can now
be positioned on the outside wall using the dr illed 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 appr oximately one quarter inch (0.6 4 cm) outside
of the marked circle. This pilot hole is used as a sta rting point
for a saws-all or sabre saw blade. Cut around the mar ked circle
staying approximately one quarter inch (0.6 4 cm) outside of the
line. (This will allow the vent to easily slide throug h 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 th is section of pipe.
Slide the wall plate over the pipe to stop against the vent termina l.
Place a bead of caulking (not supplied) around the gap bet ween the
pipeandcoverplate.Applyenoughtollsomeofthegapbetween
the pipe and wall. Place some of the caulking on the b ack of the plate
to hold it against the wall after installation. If t he vent pipe is installed
up to the wall, with a coupling on the end against the wall o pening,
the pipe with the vent terminal can be prepared fo r gluing before
inserting through the wall. Slide the pipe t hrough the wall and insert
into the coupling on the other side of the wall, making su re that the
vent terminal ends up pointed in the correct pos ition, see Figure 18.
