Secure Vent™ pipe applications are shown in these Figures; Secure Flex™ pipe may also be used. A Vertical VentTablesummarizeseachsystem’sminimum and maximum vertical and horizontal length values that can be used to design and install the vent components in a variety of applications. Both these vertical vent systems terminate through the roof. The minimum vent height above the roof and/or adjacent walls is specified in ANSI Z223.1-(latest edition) (In Canada, the current CAN/CSA-B149.1 installation code) by major building codes. Always consult your local codes for specific requirements. A general guide to follow is the Gas Vent Rule (refer to Figure 5 on Page 6). Vertical (Straight) Installation (Figure 17) Determine the number of straight vent 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 (see Tables on this page and Page 35 -Vent Sections). Plan the vent lengths so that a joint does not occur at the intersection of ceiling or roof joists. Refer to the Vent Section Length Chart. -- -- -- -- -- -- -- -- -- -- SUPERIOR DIRECT-VENT GAS FIREPLACES • MODELS SLDVT-30/35/40/45 • INSTALLATION INSTRUCTIONS SUPERIOR DIRECT-VENT GAS FIREPLACES • MODELS SLDVT-30/35/40/45 • INSTALLATION INSTRUCTIONS Analyze the vent routing and determine the quantitiesofventsectionsandnumberofelbows required. Refer to Vertical Vent Figures and Tables on Pages 16 and 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 Charts on Page 13 for an aidinselectinglengthcombinations.Elbowsare available in 90° and 45° configurations. Refer to Figure 21 on Page 15 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 joint in a undesirable location, or will not build up to the required length. The SV4.5LA Telescopic Vent Section has an effective length of from 1-1/2" (38 mm) to 7-1/2" (191 mm). The SV4.5LA is fitted with a locking inclined channel end (identical to a normalventsectioncomponent)andaplainend with 3 pilot holes. Slip the plain end over the locking channel end of a standard SV4.5 vent component the required distance and secure with three screws. Maintain a minimum 1" (25 mm) clearance to combustiblematerialsforallverticalelements. Clearances for all horizontal elements are 3" (76 mm) on top, 1" (25 mm) on sides and 1" (25 mm) on the bottom. A. Frame ceiling opening -Use a plumb line from the ceiling above the appliance to locate center of the vertical run. Cut and/or frame an opening, 10-1/2" x 10-1/2" (267mm x 267mm) inside dimensions, about this center mark (Figure 18). 14 Figure 18 10-1/2” Min. (267mm) 10-1/2” Min.

Attach vent components to appliance -SecureVent SV4.5direct-ventsystemcomponents are unitized concentric pipe components featuring positive twist lock connections (see Figure 19). 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. Figure 19 Align the dimple (4 places) of the upper vent section with the opening of the locking incline channel on the lower vent section or appliance collar.
