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 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 #8 x 3/8" screws. Maintain a minimum 1" (25 mm) clearance to combustible materials for all vertical vent elements. Clearances for horizontal vent elements are 1" (25 mm) at the sides and 1" (25 mm) on the bottom. Clearances above horizontal vent elements are 3" (76 mm) for all models and all applications. Exception:Clearance is 5" (127 mm) for MPLDV35, MPLDV40 & MPLDV45, when the center line of the horizontal run isless than 48" (1219 mm) above the fireplace top wrapper surface. The starter elbow may not be used if a 45 degree vent run is required directly off of the unit. Refer to Detail - Figure 17. A. Attach Supplied 45 Degree Starter Elbow Slip the plain end with 3 mounting holes over the locking channel end of the appliance collar and secure with three screws. B. Support The Elbows -Support the starter elbow and the vertical portions of the venting system with support bracket as shown in Figure 23- Detail A, on page 14. Do not use the starter elbow anywhere else in the vent system if not used on the appliance collar. SV4.5 rigid and flex components can be used directly off the collar. Do not return to rigid sections after using flex sections in a vent run. C. 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 14). NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE. NOTE: DIAGRAMS & ILLUSTRATIONS NOT TO SCALE. This seating position is indicated by the alignment of the arrow and dimple as shown in Figure 16. F. Install firestop/spacer at ceiling -When using Secure Vent, use SV4.5VF firestop/spacer at ceiling joists; when using Secure Flex, use SF4.5VF firestop/spacer. If there is living space above the ceiling level, the firestop/spacer must be installed on the bottom side of the ceiling. If attic space is above the ceiling, the firestop/spacer must be installed on the top side of...
