Vertical (Offset) Installation Vertical (Offset) Installation 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 ..." (38 mm) to 7 ..." (191 mm). The SV4.5LA is fitted with a locking inclined channel end (identical to a normal vent section component) and a plain end 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 combustible materials for all vertical elements. 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..." x 10..." (267mm x 267mm) inside dimensions, about this center mark (Figure 14). 10...” Min. (267 mm) 10...” Min. (267 mm) Figure 14 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 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. First Vent Component Align the dimple (four places) with the opening of the locking incline channel on appliance collar. Twist vent component clockwise to engage and seal. Dimple Locking Incline Channel Appliance collar Vent / Appliance CollarConnection Figure 15 Arrow Align the dimple (four places) of the Arrow Arrow Vent / Vent Section Connection upper vent section with the opening of the locking incline channel on the lower vent section. Twist vent component clockwise to engage and seal until arrow and dimple align. LockingIncline Channel Dimple Connected Vent Sections Figure 16 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 15). 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 ..." screw may be used at the joint, but is not required as the pipe will securely lock when twisted. Note:An elbow may also be attached to the appliance collar.Attach in the same manner as you would a vent section. 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. NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE. 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. 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...
