NOTE: The PVV-SLEEVE must be long enough to penetrate through the roof flashing a minimum of two inches.
The PVV-SLEEVE can be cut to size if the vent run does not allow the excess to extend down into the home or chase.
NOTE: If more than one PVV-SLEEVE will be used, attach the storm collar to the lowest section of PVV-SLEEVE. Secure all sections of PVV-SLEEVE with self tapping screws.
