VERTICAL VENT FIGURES/TABLES (CONTINUED) HORIZONTAL (OUTSIDE WALL) TERMINATION SYSTEM Figure 26 on Page 18, and Figures 27 to 32 on Pages 19 through 22 and their associated Horizontal Vent Table which illustrate the various horizontal venting configurations that are possible for use with these appliances. Secure Vent™ pipe applications are shown in these Figures; Secure Flex™ pipe may also be used. A Horizontal Vent Table summarizes each system’s minimum and maximum vertical and horizontal length values that can be used to design and install the vent components in a variety of applications. Both of these horizontal vent systems terminate through an outside wall. Building Codes limit or prohibit terminating in specific areas. Refer to Figure 6 on Page 7 for location guidelines. Secure Vent SV4.5 direct-vent system compo- nents are unitized concentric pipe components featuring positive twist lock connection, (refer to Figure 17 on Page 14). All of the appli- ances 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. 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" (572 mm), 34-1/2" (876 mm) and 46-1/2" (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 19 on Page 15.

This table shows a 1(V) to 5(H) ratio. For every 1 foot of (V) vertical, you are allowed 5 feet of (H+H1) horizontal run up to a maximum total horizontal run of 20 feet. An elbow is acceptable as 1 foot of vertical rise except where an elbow is the only vertical component in the system. See Figure 29.

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. Assemble the vent system to point where the terminus of the last section is located relative to the exterior surface to which the termination is to be attached as shown in Figure 28 and Table 8. 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 28, refer to Table 8 on Page 20. This Table lists the additional venting components needed (in addition to the termination and adapter) for a particular range of wall thicknesses. K. 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 in Figure 27 in the same manner as any SV4.5 vent component (refer to Step E). L. Install Firestop/Spacer at exterior wall - When using the termination, install SV4.5HF (Secure Vent™), SF4.5HF (Secure Flex™) Firestop/Spacer over the opening at the exterior side of the framing, long side up, with the 3 inch spacer clearance at the top as shown in Figure 27, and nail into place. (The Firestop/Spacer may also be installed over the opening at the interior side of framing). M. Install the Termination (SV4.5HT-2 or SV4.5HTSS) For the last step, from outside the exterior wall, slide the collars of the termination onto the adapter (the outer inside the outer and the inner outside the inner) until the termination seats against the exterior wall surface to which it will be attached. Orient the housing of the termination with the arrow pointed upwards. Secure the termination to the exterior wall. The horizontal termination must not be recessed into the ...
