Regency P33R-2 Zero Clearance Rear Vent Direct Vent Gas Fireplace 19INSTALLATIONGAS LINEINSTALLATIONThe gas line can be brought through either theright or the left side of the appliance. The gasvalve is situated on the right hand side of the unitand the gas inlet is on the right hand side of thevalve.Note: If the gas line is being installedfrom the left side, be sure to leaveroom to accommodate servicingof the fan.The gas line connection may be made of rigidpipe, copper pipe or an approved flex connec-tor. (If you are using rigid pipe, ensure that thevalve can be removed for servicing.) Sincesome municipalities have additional local codesit is always best to consult with your localauthorities and the CAN/CGA B149 installationcode.For USA installations follow local codes and/orthe current National Fuel Gas Code, ANSIZ223.1.When using copper or flex connectors use onlyapproved fittings. Always provide a union sothat gas lines can be easily disconnected forservicing. Flare nuts for copper lines and flexconnectors are usually considered to meet thisrequirement.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 2.44Dia. 4Diagram 3: The upper half of the flashing isinstalled under the roofing material and notnailed down until the chimney is installed.This allows for small adjustments.Diagram 2VERTICALTERMINATION1) Maintain the 1-1/2" clearances (air spaces)to combustibles when passing through ceil-ings, walls, roofs, enclosures, attic rafter,or other nearby combustible surfaces. Donot pack air spaces with insulation. Checkpages 13-14 for the maximum vertical riseof the venting system and themaximum horizontal offset lim-itations.2) Set the gas appliance in itsdesired location. Drop a plumbbob down from the ceiling to theposition of the appliance flueexit, and mark the locationwhere the vent will penetratethe ceiling. Drill a small hole athis point. Next, drop aplumb bob from the roof tothe hole previously drilledin the ceiling, and mark thespot where the vent willpenetrate the roof.3) A Firestop spacer must be installed in thefloor or ceiling of every level. To install theFirestop spacer in a flat ceiling or wall, cuta 10 inch square hole. Frame the hole asshown in Diagram 2 and install the firestop.Diagram 4Note: Apply sealant "Mill-Pac" to innerpipe and high temperature sili-cone sealant to outer pipe on everytwist-lock joint.pipe into the vent cap assembly. It is importantthat the vent pipe extends into the vent capsufficient distance so as to result in aminimum pipe overlap of 1-1/4 inches.Secure the connection between the ventpipe and the vent cap 3 sheet metal screws.9) Install wall thimble in the center of the 10"square and attach with wood screws(Diagram 4).4) Assemble the desired lengths of pipe andelbows. Ensure that all pipes and elbowconnections are in the fully twist-lockedposition and 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 meet theminimum requirements for clearance tocombustibles of 1-1/2". Slip the flashingunder the shingles (shingles should over-lap half the flashing) as per Diagram 3.6) Continue to assemble pipe lengths.Note: If an offset is necessary in the atticto avoid obstructions, it is impor-tant to support the vent pipe every3 feet, to avoid excessive stresson the elbows, and possible sep-aration. Wall straps are availablefor this purpose.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 vent cap meetsthe minimum height requirements specified inDia. 4 or local codes. Note that for steep roofpitches, the vertical height must be increased.A poor draft, or down drafting can result fromhigh wind conditions near big trees or adjoin-ing roof lines, in these cases, increasing thevent height may solve the problem.7) Ensure vent is vertical and secure the baseof the flashing to the roof with roofing rails,slide storm collar over the pipe section andseal with a mastic.8) Install the vertical termination cap by twist-locking it.Note: Any closets or storage spaces, whichthe vent passes through must be en-closed.Diagram 1
