F.Changeventdirectiontohorizontal/inclined run -At transition from or to a horizontal / inclined run, install the SV4.5E45 and SV4.5E90 elbows in the same manner as the straight vent sections. The elbows feature a twist section to allow them to be routed about the center axis of their initial collar section to align with the required direction of the next vent run element. Twist elbow sections in a clockwise direction only so as to avoid the possibility of unlocking any of the previously connected vent sections.

Install support straps every 5 feet (1.52 m) along horizontal / inclined vent runs using conventional plumber’s tape. See Page 20, Figure 33. It is very important thatthehorizontal/inclinedrunbemaintained in a straight (no dips) and recommended to be in a slightly elevated plane, in a direction away from the fireplace of 1/4"riseperfoot(20 mm per meter) which is ideal, though rise per foot run ratios that are smaller are acceptable all the way down to at or near level. Use a carpenter’s level to measure from a constant surface and adjust the support straps as necessary. Use a carpenter’s level to measure from a constant surface and adjust the support straps as necessary. H. Frame roof opening -Identify location for vent at the roof. Cut and/or frame opening per Roof Framing Chart and Figure 25. C D Framing Dimensions for Roof Inches (millimeters) Pitch C D 0/12 10-1/2 in. (267 mm) 10-1/2 in. (267 mm) 6/12 10-1/2 in.

Install the roof flashing over the vent section and position such that the vent column rises vertically (use carpenters level - see Figure 26 ). 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. J. Install the storm collar -Install the storm collar, supplied with the flashing, over the vent / flashing joint. See Figure 26. 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 circumference of the joint to provide a water tight seal. Storm Collar Flashing Figure 26 K. Install the vertical termination - The final Step involves installation of the SV4.5CGV-1 Vertical Termination. Extend the vent sections to the height as shown in the "Vertical vent termination section" (Page 6, Figures 3A and 3B). The SV4.5CGV-1 Vertical Termination (Figure 27) can be installed in the exact same fashion as any other Secure Vent section. Align the termination over the end of the previously installed section, adjusting the radial alignment until the four locking dimples of the termination are aligned with the inlets of the four incline channels of the last vent section. Push the termination down until it fully engages, then twist the termination clockwise running the dimples down and along the incline channels until they are seated at the end of the channels. Figure 27 If the vent system extends more than 5 feet (1.5 m) above the roof flashing, stabilizers may be necessary. Additional screws may be used at section joints for added stability. Guide wires may be attached to the joint for additional support on multiple joint configurations. NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE. 18 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.

Example: If 20 feet of (H) horizontal vent run is needed, then 4 feet minimum of (V) vertical vent will be required. This table shows a 1(V) to 5(H) ratio. For every 1 foot of (V) vertical, you are allowed 5 feet of (H) horizontal run, up to a maximum horizontal run of 20 feet. An elbow is acceptable as 1 foot of vertical rise except where an elbow is the only vertical component in the system. See Figure 37. Table ...
