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 flue collars of the fireplace. (You maywish to cut the liner shorter to make it moreworkable.)

Locate the centerline ofthe termination and mark wall accordingly.Cut an 11"(279mm) hole in the wall (insidedimension).Note: A top clearance of 2-1/2"(64mm)and side & bottom clearance of1-1/2"(38mm) must be maintainedexcept that only a 1" (25mm) clearanceis needed at the termination end. Werecommend framing a 11"(279mm) x11"(279mm) (inside dimensions) holeto give structural rigidity for mountingthe termination.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 fireplace 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 ofthe termination and slipping the 5"(127mm)liner over it at least 1-3/8" (35mm).
