Fasten the other thimblehalf to the inside wall.The thimble halves slipinside each other and can be adjusted for 2x 4 or 2 x 6 walls.5) Slip the assembled liner and terminationassembly through the thimble making surethe termination cap faces up (there aremarkings on the cap that show which wayis up). This will position the termination capwith proper down slope for draining water.Fasten the cap to the outer wall with the 4supplied screws.6) Pull the centre 5"(127mm) liner and outer8"(203mm) liner out enough to slip overthe fl ue collars of the fi replace. (You maywish to cut the liner shorter to make it moreworkable.) Do not bend liner more than 90 o.The liners must slip over the collars aminimum of 1-3/8".7) Apply Mill Pac over the fi replace inner collarand slip the 5"(127mm) liner down over itand attach with 3 supplied screws.8) Do the same with the 8"(203mm) liner.9) Apply a bead of silicone between the thimbleand termination and around the outer edgeof the terminal at the wall in order to keepthe water out.UNIT INSTALLATIONHORIZONTAL TERMINATIONWITH FLEX VENT SYSTEMNote: A top clearance of 3"(76mm) andside & bottom clearance of 2"(51mm)must be maintained; except whenpassing through a wall, ceiling, orat the termination where the use ofa fi restop or wall thimble reduces therequired clearance to 1-1/2" (38mm).We recommend framing a 11"(279mm)x 11"(279mm) (inside dimensions)hole to give structural rigidity formounting the termination.1) Locate the unit in the framing, rough in thegas (preferably on the right side of the unit).Locate the centerline of the termination andmark wall accordingly. Cut an 11"(279mm)hole in the wall (inside dimension).Note: If installing termination on a sidingcovered wall, a vinyl siding standoffor vinyl furring strips must be usedto ensure that the termination is notrecessed into the siding.2) Level the fi replace and fasten it to the fram-ing using nails or screws through the nailingstrips.3) Assemble the vent assembly by applyingMill Pac to the 5"(127mm) inner collar of thetermination and slipping the 5"(127mm) linerover it at least 1-3/8" (35mm). Fasten with the3 screws (drilling pilot holes will make thiseasier).
