Height of Vent Number of Vent Sections *inches feet T O T A L QT Y Note: Convert inches into metric equivalent measurement, as follows: Millimeters (mm) = Inches x 25.4 Centimeters (cm) = Inches x 2.54 Meters (M) = Inches x .0254 Effective Vent Length Model Effective Length SV4.5L6 4-1/2" SV4.5L12 10-1/2" SV4.5L24 22-1/2" SV4.5L36 34-1/2" SV4.5L48 46-1/2" Table 7 NOTE: DIAGRAMS & ILLUSTRATIONS ARE NOT TO SCALE. 15 Figure 17 10-1/2" Min. (267 mm) 10-1/2" Min. (267 mm) Ceiling Framing Plumb Bob 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 inlet of the four inclined channels on the collar (refer to Figure 18). 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 is not required as the pipe will securely lock when twisted. 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. B. Attach vent components to appliance - Secure Vent SV4.5 direct-vent system components are unitized concentric pipe components featuring positive twist lock connections (see Figure 18). 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. Align the dimple (four places) of the upper vent section with the opening of the locking incline channel on the lower vent section or appliance collar. Twist vent component clockwise to engage and seal until arrow and dimple align. Dimple Locking Incline Channel Connected Vent Sections Arrow Arrow Appliance Collar or Vent Section Figure 18 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 18. 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 may be used to obtain the required clearances indicated here (order H3907, SV4.5ARSA, Attic insulation shield with adjustable height from 12"-22"). See installation accessories table on Page 32. 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. Support the vertical portion of the venting system every 8 feet (2.4m) above the fireplace vent outlet. Figure 19 Blocking Support Straps (Plumber's tape) 8 feet (2.4 m) Maximum 1 inch (25.4 mm) minimum clearance to combustibles Roof Framing Vertical (Offset) Installation Analyze the vent routing and determine the quantities of vent sections and number of elbows required. Refer to Vertical Vent Figures and Tables on Page 17 to select the type of vertical installation desired. Vent sections are available in net lengths of 4-1/2" (114 mm), 10-1/2" (267 mm), 22-1/2" (572 mm), 34-1/2" (876 mm) and 46-1/2" (1181 mm). Refer to the Vent Section Length Chart on Page 14 for an aid in selecting length combinations. Elbows are available in 90° and 45° configurations. Refer to Figure 20 for the SV4.5E45 and SV4.5E90 elbow dimensional specifications. Where required, a telescopic vent section (SV4.5LA) may be used to provide the installer with an option in installing in tight and confined spaces or where the vent run made up of fixed length pieces develops a...
