Shortening of Vent Extensions

Figure 16. Illustration Showing How to Shorten Vent Extensions.

The polypropylene (PP) inside pipe should always extend 0.4 in. (10 mm) beyond the white plastic outside pipe on the male end of the vent extension. Always cut the male end of the vent pipe extension. Do not attempt to cut the female end.

Figure 17. Illustration Showing How to Determine the Length to Cut Off.

Pipes overlap by 2.5 in. (65 mm). Therefore, when cutting to size, add 2.5 in. (65 mm) to the extension pipe length (X) needed for installation. Deburr all sharp edges. Otherwise, the gaskets may get damaged, which can result in the vent system no longer being air tight.

WARNING

Improper installations of vent system and components, or failure to follow all installation instructions, can result in property damage or serious injury.
