Locate the centerline of the terminationand mark wall accordingly. Cut a 10"(254mm)hole in the wall (inside dimension).Note: To make the installation more aestheticallypleasing, we recommend framing out asquare to mount the terminal to.*If this is an outside corner, the minimum distance between the vent and the outsidecorner is 6" (15cm) with AstroCap termination cap or 12" (30cm) with Dura-Vent ter-mination cap. See "F" in the diagram in "Exterior Vent Termination Locations" Section.Note: A 2-1/2" (64mm) horizontal top and1-1/2" (38mm) horizontal sides & bottomclearance around the liner must be main-tained except that only a 1" (25mm) clear-ance is needed at the termination end.We recommend framing a 10"(254mm)x 10"(254mm) (inside dimensions) holeto give structural rigidity for mountingthe termination.Note: If installing termination on a sidingcovered wall, furring strips must beused to ensure that the termination isnot recessed into the siding.2) Level the fireplace and fasten it to the framingusing nails or screws through the nailing strips.3) Assemble the vent assembly by applyingMill Pac to the 4"(100mm) inner collar of thetermination and slipping the 4"(100mm) linerover it at least 1-3/8" (35mm). Fasten with the 3screws (drilling pilot holes will make this easier).Apply Mill Pac or high temperature silicone tothe 6-7/8"(175mm) flex pipe and slip it over the6-7/8" outer collar of the vent terminal at least1-3/8"(35mm) and fasten with the 3 screws.4) Separate the 2 halves of the wall thimble andsecurely fasten the one with the tabs to theoutside wall making sure that the tabs are ontop and bottom. Fasten the other thimble halfto the inside wall. The thimble halves slip insideeach other and can be adjusted for 2 x 4 or 2 x6 walls. The liners must slip over the collarsa minimum of 1-3/8".5) Slip the assembled liner and termination as-sembly through the thimble making sure thetermination cap faces up (there are markingson the cap that show which way is up). This willposition the termination cap with proper downslope for draining water. Fasten the cap to theouter wall with the 4 supplied screws.6) Pull the centre 4"(100mm) liner and outer6-7/8"(175mm) liner out enough to slip overthe flue collars of the fireplace.7) Apply Mill Pac over the fireplace inner collarand slip the 4"(100mm) liner down over it andattach with 3 supplied screws.8) Do the same with the 6-7/8"(175mm) liner.9) Apply a bead of silicone between the thimbleand termination and around the outer edge ofthe terminal at the wall in order to keep thewater out.IMPORTANT: Do not locate terminationhood where excessive snow or icebuildup may occur. Be sure to checkvent termination area after snow falls,and clear to prevent accidental blockageof venting system. When using snowblowers, make sure snow is not directedtowards vent termination area.
