8. Place the Vertical Support Clamp (5000576), around the top of the

hole in the bottom of the Support Box. See Figure 21.

9. Connect the necessary amount of pipe sections to reach the UBB at a

point where the Vent Cap will extend a minimum of 24 inch (61 cm)

above the roof. See Figure 22.

10. Run the assembled pieces of vent pipe down through the Clamp of

the Support Box and connect to the appliance with an Elbow and

Starter Collar. See General Vent Installation Instructions for details on

connecting the pipe together.

11. Using a level, make slight adjustments in the position of the appliance

until the pipe is truly vertical. Tighten the bolts in the Clamp.

12. Slip the Flashing over the pipe section(s) protruding through the roof.

Secure the base to the roof with rooﬁng nails. Insure that the rooﬁng

material overlaps the top edge of the Flashing. See Figure 22.

13. Seal all nail heads with high-temperature waterproof sealant. To

ﬁnish, apply high-temperature waterproof sealant where the Storm

Collar will meet the Vent and Flashing; slide Storm Collar down until it

sets on the Flashing, put the Vent Cap on and push to lock. See Figure

14 (page 16).
