Regency P33R-2 Zero Clearance Rear Vent Direct Vent Gas Fireplace18INSTALLATIONDiagram 3HORIZONTAL INSTALLATIONSDiagram 1b) Horizontal runs of vent must be sup-ported every three feet. Wall straps areavailable for this purpose.5) Mark the wall for a 10" x 10" square hole.The center of the square hole should line upwith the centerline of the horizontal pipe.Cut and frame the 10 inch square hole in theexterior wall where the vent will be termi-nated. If the wall being penetrated is con-structed of non-combustible material, i.e.masonry block or concrete, a 7"(178mm)diameter (7-1/2"(191mm) dia. for flex) holeis acceptable. See Horizontal Terminationdiagram on page 14.Note: With Dura-Vent, the minimumheight is achieved by installing a90 o elbow directly to the flue adapt-er.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 andmay present the possibility of a fire.b) The location of the horizontal vent ter-mination on an exterior wall must meetall local and national building codes,and must not be blocked or obstructed.For External Vent Terminal Locations,see diagram on page 9.c) Snorkel Terminations:For installations requiring a vertical riseon the exterior of the building, 14-inchand 36-inch tall Snorkel Terminationsand the Riser Vent as shown in Dia. 2& 2a are available. Follow the sameinstallation procedures as used forstandard Horizontal Termination. NEV-ER install the snorkel upside down.*As specified in CGA B149 Installation Code.Local codes or regulations may require differ-ent clearances.Diagram 2Below Grade Snorkel InstallationIf the Snorkel Termination must be in-stalled below grade, i.e. basement ap-plication, proper drainage must be pro-vided to prevent water from enteringthe Snorkel Termination. Refer to Dura-Vent Installation instructions for de-tails. Do not attempt to enclose theSnorkel within the wall, or any othertype of enclosure.6) The arrow on the vent cap should bepointing up. Insure that the 1-1/2" clear-ances to combustible materials are main-tained (Dia. 3). Install the termination cap.AstroCapTM or Dura-Vent Horizontal Ter-mination Cap may be used.Diagram 2aInstall the vent system according to the manu-facturer's instructions included with the com-ponents.1) Set the unit in its desired location. Check todetermine if wall studs or roof rafters are inthe way when the venting system is at-tached. If this is the case, you may want toadjust the location of the unit. Rough in thegas preferably on the right side of the unitand the electrical (junction block is on the leftside) on the left.2) Direct Vent pipe and fittings are designedwith special twist-lock connections to con-nect the venting system to the applianceflue outlet. A twist-lock appliance adaptor isan available option that must be used inconjunction with the Simpson Dura-VentDirect Vent GS system.3) Put a bead of silicone inside the outersection of the adapter and a bead of StoveMate on the inner collar. Slip the adapterover the existing inner and outer flue collarand fasten to the outer collar only with the3 supplied screws (drilling pilot holes willmake this easier). Level the fireplace andfasten it to the framing using nails or screwsthrough the nailing strips.4) Assemble the desired combination of pipeand elbows to the appliance adaptor andtwist-lock for a solid connection.Note:a) Twist-lock procedure: Four indentations,located on the female ends of pipes andfittings, are designed to slide straightonto the male ends of adjacent pipesand fittings, by orienting the four pipeindentations so they match and slide into the four entry slots on the male ends,Dia. 1. Push the pipe sections complete-ly together, then twist-lock one sectionclockwise approximately one-quarterturn, until the two sections are fullylocked. The female locking lugs will notbe visible from the outside, on the BlackPipe or fittings. They may be located byexamining the inside of the female ends.Note: Apply sealant "Mill-Pac" to innerpipe and high temperature sili-cone sealant to outer pipe on eve-ry twist-lock joint.The four wood screws provided should bereplaced with appropriate fasteners forstucco, brick, concrete, or other types ofsidings.Note: If installing termination on a sidingcovered wall, a vinyl siding stand-off or furring strips must be usedto ensure that the termination isnot recessed into the siding.7) Before connecting the horizontal run ofvent pipe to the vent termination, slide theWall Thimble (Part # 620-926) over the ventpipe.8) Slide the appliance and vent assembly to-wards the wall carefully inserting the vent
