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. uWhen using Secure Flex, use Firestop / Spacer SF4.5VF vWhen using Secure Flex, use Firestop / Spacer SF4.5HF H1VV1HVH1HV1Figure 30 - Side Vent - THREE ELBOWS Figure 31 -Top Vent - THREE ELBOWS uCeiling Firestop / Spacer (SV4.5VF) vWall Firestop/ Spacer (SV4.5HF) uCeiling Firestop / Spacer (SV4.5VF) uWhen using Secure Flex, use Firestop / Spacer SF4.5VF vWhen using Secure Flex, use Firestop / Spacer SF4.5HF uCeiling Firestop / Spacer vWall Firestop/ (SV4.5VF) Spacer (SV4.5HF) VERTICAL VENT FIGURES / TABLES (CONTINUED) Table D H + H1 Maximum V Minimum feet (meter) feet (meter) 5 (1.524) Elbow Only 5 (1.524) 1 (0.305) 10 (3.048) 2 (0.610) 15 (4.572) 3 (0.914) 20 (6.096) 4 (1.219) H + H1 = 20 feet (6.096 m) Max.

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 36.

Secure Vent™ pipeapplicationsare showninthese figures; Secure Flex™ pipemay also be used (see Page 24). 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. Bothof these horizontalventsystemsterminate 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 components are unitized concentric pipe components featuring positive twist lock connection, (refer to Figure 20 on Page 15). 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. 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 section joint does not occur within the space definedbyceilingjoists,roof raftersorwallstuds.
