Push the vent component against the collar 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. The unitized design of the Secure Vent™ components will engage and seal both the inner and outer pipe without the need for sealant or screws. If desired a #6 x 1/2" screw may be used at the joint, but it not required as the pipe will securely lock when twisted. Note: An elbow may also be attached to the appliance collar. Attach in the same manner as you would a vent section. C. Attach vent components to each other -Other vent sections may be added to the previously installed section in accordance with the requirements of the vertical vent Figures and Tables. 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 20. NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE. D. Install firestop / spacer at ceiling -When using Secure Vent, use SV4.5VF firestop / 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 / spacer must be installed on the top side of the joist. Route the vent sections through the framed opening and secure the firestop / spacer with 8d nails or other 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. Attic insulation shield (H3907) may be used to obtain the required clearances indicated here. See installation accessories o n Pages 33 and 34. The gap between the vent pipe and a vertical firestop can be sealed with non-combustible caulking. E. Support the vertical vent run sections Note -Proper venting support is very important. The weight of the vent must not be supported by the fireplace in any degree. Supporttheverticalportionoftheventingsystem every 8 feet (2.4 m) above the fireplace vent outlet. 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 to the framing. If desired, sheet metal screws #6 x 1/2" length may be used to secure the support straps to the vent pipe. See Figure 21. Blocking Support Straps (Plumber's tape) 8 feet (2.4 m) Maximum 1 inch (25.4 mm) minimum clearance to combustibles Figure 21 Another method, where the vent is not adjacent to a wall, is illustrated in Figure 22 on Page 16. Here, support straps (96K93) and support plates (96K92) can be used to support the weight of the vent. vSV4.5VF Firestop / spacer uSV4.5SU Support Strap 8 ft.

Install support straps every 5 feet (1.52 m) along horizontal / inclined vent runs using conventional plumber’s tape. See Page 19, Figure 32.
