3. Once the installer has determined the termination
location, cut 2 holes in the wall large enough
to accommodate the pipe. Pipe diameters and
distance between hole centers can be found in
Table 4.
4. Slide both the intake and vent pipe through the
holes. Solvent weld both pipes to the Base of the
vent termination kit (see Figure 13) following the
solvent welding procedures outlined in this guide.

5. To fasten the Base to the wall, use the supplied screws
and anchors. A 3/16" diameter x 1-3/16" deep hole, will
need to be drilled for the anchors. Locate and mark
the anchor hole using the Base as a template and
then drill the required holes.
6. Screw the Cap to the Base using the supplied
screws.
7. Once the vent termination and pipe are secured,
the wall penetrations will need to be sealed from the
interior using a PVC-compatible sealant material.
