Regency PG121/PG131 Zero Clearance Room Sealed Gas Fireplace20Diagram 3Diagram 5Diagram 1Diagram 2Note: Apply sealant "Mill-Pac" to inner pipeand high temperature silicone seal-ant to outer pipe on every twist-lockjoint.TERMINATION1) Maintain the 1-1/4" clearances (air spaces)to combustibles when passing through ceil-ings, walls, roofs, enclosures, atticrafter, or other nearby combustiblesurfaces. Do not pack air spaceswith insulation. Check pages 17-19for the maximum vertical rise of theflueing system and the maximumhorizontal offset limitations.2) Set the gas appliance in its desiredlocation. Drop a plumb bob downfrom the ceiling to the position ofin the ceiling, and mark the spot where theflue will penetrate the roof. Determine if ceil-ing joists, roof rafters or other framing willobstruct the flueing system. You may wish torelocate the appliance or to offset, as shownin Diagram 2 to avoid cuttingload bearing members.3) A F i r e s t o pspacer must beinstalled in thefloor or ceilingof every level.To install theFirestop spacerin a flat ceiling or wall, cut a 10 inch squarehole. Frame the hole as shown in Diagram3 and install the firestop.4) Assemble the desired lengths of pipe andelbows. Ensure that all pipes and elbow con-nections are in the fully twist-locked positionand sealed.5) Cut a hole in the roof centered on the smalldrilled hole placed in the roof in Step 2. Thehole should be of sufficient size to meetthe minimum requirements for clearanceto combustibles of 1-1/4". Slip the flashingunder the shingles (shingles should overlaphalf the flashing) as per Diagram 4.6) Continue to assemble pipe lengths.Roof Pitch Minimum Vent HeightFeet Metersflat to 7/12 2 0.61over 7/12 to 8/12 2 0.61over 8/12 to 9/12 2 0.61over 9/12 to 10/12 2.5 0.76over 10/12 to 11/12 3.25 0.99over 11/12 to 12/12 4 1.22over 12/12 to 14/12 5 1.52over 14/12 to 16/12 6 1.83over 16/12 to 18/12 7 2.13over 18/12 to 20/12 7.5 2.29over 20/12 to 21/12 8 2.44Diagram 4: The upper half of the flashing isinstalled under the roofing material and notnailed down until the chimney is installed. Thisallows for small adjustments.Note: If an offset is necessary in the atticto avoid obstructions, it is importantto support the fl ue pipe every 3 feet,to avoid excessive stress on the el-bows, and possible separation. Wallstraps are available for this purpose(Diagram 2).Galvanized pipe is desirable above the roof-line due to its higher corrosion resistance.Continue to add pipe sections through theflashing until the height of the flue cap meetsthe minimum height requirements specifiedin Diagram 5 or local codes. Note that forsteep roof pitches, the vertical height mustbe increased. A poor draft, or down draftingthe appliance flue exit, andmark the location wherethe flue will penetrate theceiling. Drill a small holeat his point. Next, drop aplumb bob from the roof tothe hole previously drilledDiagram 3Diagram 4Diagram 5pipe to the flue termination, slide the WallThimble (Part # 942) over the flue pipe.8) Slide the appliance and flue assemblytowards the wall carefully inserting the fluepipe into the flue cap assembly. It is importantthat the flue pipe extends into the flue capsufficient distance so as to result in a mini-mum pipe overlap of 1-1/4 inches. Securethe connection between the flue pipe andthe flue cap by attaching the two sheet metalstrips extending from the flue cap assemblyinto the outer wall of the flue pipe. Use thetwo sheet metal screws provided to connectthe strips to the pipe section. See Diagram4.9) Install wall thimble in the center of the 10"square and attach with wood screws (Dia-gram 5).VERTICALINSTALLATION
