Regency ® P40-1 Direct Vent Gas Fireplace22INSTALLATIONINSTALLATIONDiagram 7Diagram 610) Install wall thimble in the center of the 11"(279mm) square and attach with woodscrews (Diagram 7).Diagram 57) Insure that the 1-1/4"(32mm) pipe clearancesto combustible materials are maintained(Diagram 5). Install the termination cap.Note: If installing termination on a vinylsiding covered wall, a vinyl sidingstandoff or furring strips must beused to ensure that the terminationis not recessed into the siding.The four wood screws provided shouldbe replaced with appropriate fasteners forstucco, brick, concrete, or other types ofsidings.8) Before connecting the horizontal run of ventpipe to the vent termination, slide the WallThimble (Part # 1247) over the vent pipe,required in Canada.9) Slide the appliance and vent assemblytowards the wall carefully inserting thevent pipe into the vent cap assembly. It isimportant that the vent pipe extends into thevent cap sufficient distance so as to resultin a minimum pipe overlap of 1-1/4 inches(32mm). Secure the connection between thevent pipe and the vent cap by attaching thetwo sheet metal strips extending from thevent cap assembly into the outer wall of thevent pipe. Use the two sheet metal screwsprovided to connect the strips to the pipesection. See Diagram 6.UNIT INSTALLATIONWITH HORIZONTALTERMINATION(Rigid Vent Systems)Install the vent system according to themanufacturer's instructions included with thecomponents.1) Set the unit in its desired location. Checkto determine if wall studs or roof raftersare in the way when the venting system isattached. If this is the case, you may wantto adjust the location of the unit. Rough inthe gas preferably on the right side of theunit and the electrical (junction block is onthe left side) 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 Simpson Dura-VentDirect Vent GS system. Install the adaptorafter the unit is set in its desired location.Put a bead of high temperature siliconeinside the outer section of the adapter anda bead of Mill Pack on the inner collar. Slipthe adapter over the existing inner and outerflue collar. Fasten to the outer collar only withthe 3 supplied screws (drilling pilot holes willmake this easier).4) Level the fireplace and fasten it to the framingusing nails or screws through the top andside nailing strips.5) Assemble the desired combination of pipeand elbows to the appliance adaptor andtwist-lock for a solid connection.Note: For best results and optimumperformance with each approvedventing system, it is highlyrecommended to apply “Mill-Pac”sealant (supplied) to every innerpipe connection. Failure to do somay result in drafting or performanceissues not covered under warranty.Silicone (red RTV) is optional.Diagram 16) Mark the wall for a 11" x 11" (279mm x279mm) square hole. The center of thesquare hole should line up with the center-line of the horizontal pipe. Cut and frame the11 inch (279mm) square hole in the exteriorwall where the vent will be terminated. Seediagram 2 for center line requirements.If the wall being penetrated is constructedof non-combustible material, i.e. masonryblock or concrete, an 8" (203mm) diameterhole is acceptable.Diagram 2Note: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 andmay present the possibility of a fire.The arrow on the vent cap should bepointing up.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"Horizontal runs of vent must be supportedevery 3 feet (0.9meter). Wall straps areavailable for this purpose.
