7. Change vent direction of horizontal/inclined run—Install
the SV4.5E45 and SV4.5E90 elbows in the same manner as
the straight vent sections. See Vent elbows on Page 15 for
more information.
8. Continue installation of horizontal/inclined sections—Con-
tinue with the installation of the straight vent sections in
horizontal/inclined run. Install support straps every 5 ft (1.52
m) along horizontal/inclined vent runs using conventional
plumber's tape. Rise per foot run ratios are acceptable all
the way to level. For best results, maintain the horizontal/
inclined run in a straight (no dips), slightly elevated plane
of approximately 1/4" per 1 ft (20 mm per 1 m). Maintain
the required clearances to combustibles (Page 7).
9. Frame the roof opening—Identify the location for the vent
at the roof. Cut and/or frame opening (Figure 19).

10. Install the roof flashing—Extend the vent sections through
the roof structure. Install the roof flashing over the vent
section and position such that the vent column rises verti-
cally (use carpenters level). Nail along perimeter to secure
flashing or adjust roofing to overlap the flashing edges at
top and sides only and trim where necessary. Seal the top
and both sides of the flashing with waterproof caulking.
11. Install the storm collar—Install the storm collar, supplied
with the flashing, over the vent/flashing joint (Figure 20).
Loosen the storm collar screw. Slide collar down until it
meets the top of the flashing. Tighten the adjusting screw.
Apply non-combustible caulking or mastic around the cir-
cumference of the joint to provide a water tight seal.
