Install the termination cap.Note: If installing termination on a vinylsiding covered wall, a vinyl sidingstandoff or furring strips must be usedto ensure that the termination is notrecessed into the siding.The four wood screws provided should be re-placed with appropriate fasteners for stucco,brick, concrete, or other types of sidings.8) Before connecting the horizontal run of ventpipe to the vent termination, slide the WallThimble over the vent pipe. The wall thimbleis required for all horizontal terminations.9) Slide the appliance and vent assemblytowards the wall carefully inserting the ventpipe into the vent cap assembly. It is importantthat the vent pipe extends into the vent capsufficient distance so as to result in a minimumpipe overlap of 1-1/4 inches (32mm). Securethe connection between the vent pipe andthe vent cap.10) Install wall thimble in the center of the framedhole and attach with wood screws (Diagram7).Install the vent system according to themanufacturer's instructions included with thecomponents.1) Set the unit in its desired location. Check todetermine if wall studs or roof rafters are inthe way when the venting system is attached.If this is the case, you may want to adjustthe location of the unit. Rough in the gaspreferably on the right side of the unit andthe electrical (junction block is on the leftside) on the left.2) Direct Vent pipe and fittings are designed withspecial twist-lock connections to connect theventing system to the appliance flue outlet.A twist-lock appliance adaptor is required.3) In conjunction with the Approved Ventsystem, install the adaptor after the unit isset in its desired location. Put a bead of hightemperature silicone inside the outer sectionof the adapter and a bead of Mill Pack on theinner collar. Slip the adapter over the existinginner and outer flue collar. Fasten to the outercollar only with the 3 supplied screws (drillingpilot holes will make this easier).4) Level the fireplace and fasten it to the framingusing nails or screws through the top andside nailing strips.Diagram 1Note: For best results and optimumperformance with each approvedv e n t i n g s y s t e m , i t i s h i g h l yrecommended to apply “Mill-Pac”sealant (supplied) to every innerpipe connection. Failure to do somay result in drafting or performanceissues not covered under warranty.Horizontal runs of vent must besupported every 3 feet (0.9meter). Wallstraps are available for this purpose.Diagram 26) Mark the wall for a square hole.-see chart toleft for size. The center of the square holeshould line up with the center-line of thehorizontal pipe. Cut and frame the squarehole in the exterior wall where the vent willbe terminated. See diagram 2 for center linerequirements.If the wall being penetrated is constructed ofnon-combustible material, i.e. masonry blockor concrete, an 8" (203mm) diameter holeis acceptable.Note:a) The horizontal run of vent must be level,or have a 1/4 inch rise for every 1 footof run towards the termination. Neverallow the vent to run downward. Thiscould cause high temperatures and maypresent the possibility of a fire.b) The location of the horizontal venttermination on an exterior wall must meetall local and national building codes, andmust not be blocked or obstructed. See"Exterior Vent Termination Locations"section for more details.5) Assemble the desired combination of pipeand elbows to the appliance adaptor andtwist-lock for a solid connection.Recommended Framed OpeningSizeVent Size Framing Size4" x 6 - 5/8" 10" x 10"Horizontal Top* 3" (76mm)*Horizontal Side 2 " (51mm)Horizontal Bottom 2" (51mm)Vertical Vent 2" (51mm)Minimum Vent Clearancesto CombustiblesUNIT INSTALLATION WITHHORIZONTALTERMINATION4" X 6-5/8"VENTING(Rigid Vent Systems)Below are the recommended framingdimensions (inside measurements) for the4" x 6-5/8" rigid vent terminations - for usewith a firestop or wall thimble.* Clearances noted below must be maintained;except when passing through a wall, ceiling or at thetermination where the use of a firestop or wall thimblereduces clearance to 1-1/2" (38mm).CLCL3 " ( mm)6 914Min. height(Flex or Rigid)centerof hole
