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.

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.
