Installation Procedure
1. Once the proper location has been determined, cut
2 holes in the wall large enough to accommodate
the pipe. Pipe diameters and distance between hole
centers can be found in Table 2.
2. Slide both the intake and exhaust pipes through the
holes. Solvent cement both pipes to the base of the
vent termination kit, follow the solvent cementing
procedures outlined in the System 636 Installation
Guide.
3. To fasten the Base to the wall, use the supplied screws
and anchors. A 3/16” hole, 1-3/16” deep, will need to
be drilled for the anchors. Locate the anchor hole using
the base as a template.
4. Screw the Cap to the Base using the supplied screws.
5. Once the vent termination and pipes are secured,
the wall penetrations will need to be sealed from the
interior using a PVC-compatible sealant material.
