components as shown in Figure 31 and pre-install the roof
jack assembly to the hard pipe approximately 18” from the
top end of the hard pipe.

roof, then lowered through the roof cutout opening (see step

14. Secure the roof support assembly to the roof sheathing with
at least (4) nails/screws through each support bracket. Check
that the combustible clearances through the roof framing will
maintain at least a 1” clearance from the vent pipe.
15. Determine how high the vent terminal should be located
above the roof line based on the roof pitch information shown
in Figure 32. Adjust the vent system height by loosening the
pre-installed roof support pipe clamp and sliding the vent
pipe up or down as pre-determined, then re-tighten the pipe
clamp. Install a couple of sheet metal screws through the pipe
clamp into the outer hard vent pipe to lock in place.
