To add another vent component to a length of vent run, align the dimpled end over the inclined channel end of the previously installed section, adjusting the radial alignment until the four locking dimples are aligned with the inlets of the four incline channels of the previous section. Push the vent component against the previous section until it fully engages, then twist the componentclockwiserunningthedimplesdown and along the incline channels until they seat at the end of the channels. This seating position is indicated by the alignment of the arrow and dimple as shown in Figure 22. D. Install firestop/spacer at ceiling -When usingSecureVent,useSV4.5VFfirestop/spacer at ceiling joists; when using Secure Flex, use SF4.5VF firestop/spacer. If there is living space above the ceiling level, the firestop/spacer must be installed on the bottom side of the ceiling. If attic space is above the ceiling, the firestop/spacermustbeinstalledonthetopside of the joist. Route the vent sections through the framed opening and secure the firestop/spacer with 8d nails or other appropriate fasteners at eachcorner.Remembertomaintain1"(25mm) clearancetocombustibles,framingmembers, and attic or ceiling insulation when running vertical chimney sections. Attic insulation shield (H3907) may be used to obtain the required clearances indicated here. See installation accessories Pages 31 & 32. E. Support the vertical vent run sections Note- Properventingsupportisveryimportant. The weight of the vent must not be supported by the fireplace in any degree. Support the vertical portion of the venting system every 8 feet (2.4m) above the fireplace vent outlet. Blocking Support Straps (Plumber's tape) 8 feet (2.4 m) Maximum 1 inch (25.4 mm) minimum clearance to combustibles Figure 23 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE. One method of support is by utilizing field provided support straps (conventional plumber's tape). Secure the plumber's tape to the framing members with nails or screws. Loop the tape around the vent, securing the ends of the tape tothe framing. Ifdesired,sheet metal screws#6 x 1/2" length may be used to secure the support straps to the vent pipe. Refer to Figure 23. 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 possiblity of unlocking anyofthepreviouslyconnectedventsections. See Figure 24.

Install support straps every 5 ft. (1.52 m) along horizontal/inclined vent runs using conventional plumber’s tape. See Page 17, Figure 33. It is very important thatthehorizontal/inclinedrun be maintained in a straight (no dips) and recommended to be inaslightlyelevatedplane,inadirectionaway from the fireplace of 1/4 " rise per foot (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. It is important to maintain the required clearances to combustibles: 1" (25 mm) at all sides for all vertical runs; and 3" (76 mm) at the top, 1" (25 mm) at sides, and 1" (25 mm) at the bottom for all horizontal/inclined runs. H. Frame roof opening -Identify location for vent at the roof. Cut and/or frame opening per Roof Framing Chart (Figure 25). CD 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. (267 mm) 12 in. (305 mm) 12/12 10-1/2 in. (267 mm) 17 3/4 in. (451 mm) Figure 25- Roof Framing I. 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 vertically (use carpenters level) (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. Figure 26 Storm Collar K. Inst...
