Both of these horizontal vent systems terminate through an outside wall. Building Codes limit or prohibit terminating in specific areas. See Figures 5 and 6 on Pages 6 and 7 for location guidelines. Secure Vent SV4.5 direct-vent system components are unitized concentric pipe components featuring positive twist lock connection, (refer to Figure 21 on Page 14). All of the appliances covered in this document are fitted with collars having locking inclined channels. The dimpled end of the vent components fit over the appliance collar to create the positive twist lock connection. NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE. A. Plan the vent run Analyze the vent routing and determine the types and quantities of sections required 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2" (572mm),34-1/2"(876mm)and46-1/2"(1181 mm) net section lengths are available. It is recommended that you plan the vent lengths so that a joint does not occur at the intersection of ceiling or roof joists. Make allowances for elbows as indicated in Figure 25 (Page 15). Maintain a minimum 1" (25 mm) clearance to combustibles on the vertical sections. Clearances for the horizontal runs are; 3" (76 mm) on top, 1" (25 mm) on sides, and 1" (25 mm) at the bottom.

B. Frame exterior wall opening Locate the center of the vent outlet on the exterior wall according to the dimensions shown in Figure 12 on Page 10. Cut and/or frame an opening, 10-1/2" x 12-1/8" (267 mm x 308 mm) inside dimensions, about this center. C.

D. Attach vent components to appliance - To attach a vent component to the appliance collar, align the dimpled end over the collar, adjusting the radial alignment until the four locking dimples are aligned with the inlets of the four incline channels on the collar (refer to Figure 21 on Page 14). Push the vent component against the collar until it fully engages, then twist the component clockwise,runningthedimplesdownandalong the incline channels until they seat at the end of the channels. The unitized design of the Secure Vent components will engage and seal both the inner and outer pipe elements with the same procedure. Sealant and securing screws are not required. Note: An elbow may also be attached to the appliance collar. Attach in the same manner as you would a vent section. E.Attach vent components to each other -Other vent sections may be added to the previously installed section in accordance with the requirements of the vent tables. To add another vent component to a length of vent run, align the dimpled end of the component 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 component clockwise running the dimples down 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 21 on Page 14. F. Install firestop/spacer at ceiling between stories -Install a firestop/spacer (catalog no. H2247-SecureVent;catalogno.H2249-Secure Flex) at the bottom side of the ceiling to the ceiling joists. Route the vent sections through the framed opening and secure the firestop/spacer with appropriate fasteners at each corner. Remember to maintain 1" (25 mm) clearance to combustibles, framing members, and attic or ceiling insulation when running vertical chimney sections. G. Support the vertical run sections - See Section E on Page 15. On the vertical run, support the venting system every 8 feet (2.4m) above the fireplace vent outletwithfieldprovidedsupportstraps( Plumber's tape). Attach the straps to the vent pipe and secure to the framing members with nails or screws. See Figure 24 on Page 15. NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE.
