Note:An elbow may also be attached to the appliance collar.Attach in the same manner as you would a vent section. Remember to maintain 1" (25 mm) clearance to combustibles, framing members, and attic or ceiling insulation when running vertical chimney sections. 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 16 on page 10. I. Continue installation of horizontal/inclined sections -Continue with the installation of the straight vent sections in horizontal/inclined run as described in Step E. Install support straps every 5 ft. (1.52 m) along horizontal/ inclined vent runs using conventional plumber’s tape. See Figure 28. It is very important that the horizontal/inclined run be maintained in a straight (no dips) and recommended to be in a slightly elevated plane, in a direction away from the fireplace of ..." 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. G. Support the vertical run sections On the vertical run, support the venting system every 8 feet (2.4m) above the fireplace vent outlet with field provided support straps (Plumber's tape). Attach the straps to the vent pipe and secure to the framing members with nails or screws. See Figure 17 on page 10. J. Assemble vent run to exterior wall -If not previously measured, locate the center of the vent at the exterior wall. Prepare an opening as described in Step B When using square (SV4.5 HTS), short square (SV4.5 HTSS) or round (SV4.5HTR) horizontal termination Assemble the vent system to point where the terminus of the last section is within 6 in. (152 mm) to 10... in. (260 mm) inboard of the exterior surface to which the termination is to be attached, see Figure 31 on page 15. Sealant and securing screws are not required. 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. If the terminus of the last section is not within this distance, use the telescopic vent section SV4.5LA, as the last vent section. For wall thicknesses greater than that shown in Figure 31, refer to table 3 on page 16. This table lists the additional venting components needed (in addition to the termination and adapter) for a particular range of wall thicknesses. K. When using square (SV4.5HTS) or short square (SV4.5 HTSS) horizontal termination - attach termination adapter Attach the adapter (adapter - SV4.5RCH - provided with the termination) to the vent section or telescoping vent section), elbow or appliance collar as shown inFigure 29in the same manner as any SV4.5 vent component (refer to Step E). When using long square (SV4.5HTSSL) horizontal termination Assemble the vent system to point where the terminus of the last section is within 0 in. (0 mm) to 9......
