OUTSIDE VERTICAL INSTALLATIONS:
To accomplish a outside vertical pipe installation, follow steps 1 through 5 in the “INSIDE VERTICAL
INSTALLATIONS” section and then finish it by performing the following (refer to Figure 19).
1. Install a tee with clean out on the outside of the house.
2. Install PL vent upward from the tee. Make sure that you install support brackets to keep the vent
straight and secure.
3. Install ceiling thimble and secure the flashing as you go through the roof.
4. Ensure that the rain cap is approximately 24” (610 mm) above the roof.
