Install Instructions

► Cut a square hole and clear any roofing material so frame with proper minimum opening can be installed (See Table 9).
► When cutting the opening, allowance must be made for the thickness of the frame.
NOTICE
In the event that roof joists must be cut - follow the building codes having jurisdiction for reframing the opening.
► For roof curb installations (recommended): Refer to minimum opening in Table 9 for framing size for masonry pour
and Table 8 for roof jack dimensions. Roof curbs may also be purchased at your local building supply store.

INSTALLING VENT PIPE THROUGH ROOF JACK SUPPORT SYSTEM
Where double wall pipe with ZV-Clamp is to be used with a roof jack assembly, do not install the ZV-Clamp inside the roof jack.
Instead install mating flanges in slotted sections located in Pipe Joint Range of Roof Jack Coupling assembly (See Illustration 4)
supplied with the Roof Jack Support System. Connect the two prescribed lengths of pipe (above and below roof) and couple them
together with Roof Jack Coupling Assembly. Position the pipe joint in the notched area of the coupling assembly (See Illustration 5).
Tighten the lock-nuts onto the bolts that clamp the assembly onto the pipe to a torque specification of 70 in/lbs. / 6 ft-lbs / 8
Nm.
