30 | Regency ® P33-10 Zero Clearance Direct Vent Gas Fireplace|30installationGAS LINEINSTALLATIONThe gas line is brought through the right sideof the appliance. The gas valve is situated onthe right hand side of the unit and the gas inletis on the right hand side of the valve.The gas line connection may be made ofrigid pipe, copper pipe or an approved flexconnector. (If you are using rigid pipe, ensurethat the valve can be removed for servicing.)Since some municipalities have additionallocal codes it is always best to consult withyour local authorities and the CAN/CGA B149installation code.For USA installations follow local codesand/or the current National Fuel Gas Code,ANSI Z223.1.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 meetthis requirement.Important: Always check for gas leakswith a soap and water solution or gas leakdetector. Do not use open flame for leaktesting.Diagram 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 2UNIT INSTALLATIONWITH VERTICALTERMINATION1) Maintain the 1-1/2" clearances (air spaces) tocombustibles when passing through ceilings,walls, roofs, enclosures, attic rafter, or othernearby combustible surfaces. Do not packair spaces with insulation. Check "Venting"Sections for the maximumvertical rise of the ventingsystem and the maximumhorizontal offset limitations.2) Set the gas appliance in itsdesired location. Drop a plumbbob down from the ceiling tothe position of the applianceflue exit, and mark the locationwhere the vent will penetratethe ceiling. Drill a smallhole at this point. Next,drop a plumb bob from theroof to the hole previouslydrilled in the ceiling, andmark the spot where thevent will penetrate 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,cut a 10 inch square hole. Frame the holeas shown in Diagram 2 and install thefirestop.Diagram 4NOTE: For best results and optimumperformance with each approved ventingsystem, it is highly recommended to apply“Mill-Pac” sealant (supplied) to every in-ner pipe connection. Failure to do so mayresult in drafting or performance issues notcovered under warranty. Silicone (red RTV)is optional.8) 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.Secure the connection between the ventpipe and the vent cap 3 sheet metal screws.9) Install wall thimble in the center of the10" 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 meetthe minimum requirements for clearanceto combustibles of 1-1/2". Slip the flashingunder the shingles (shingles should overlaphalf the flashing) as per Diagram 3.6) Continue to assemble pipe lengths.Note: If an offset is necessary in the attic toavoid obstructions, it is important tosupport the vent pipe every 3 feet, toavoid excessive stress on the elbows,and possible separation. Wall strapsare available for this purpose.Galvanized pipe is desirable above the rooflinedue to its higher corrosion resistance. Continueto add pipe sections through the flashing untilthe height of the vent cap meets the minimumheight requirements specified in Dia. 4 or localcodes. Note that for steep roof pitches, thevertical height must be increased. A poordraft, or down drafting can result from highwind conditions near big trees or adjoiningroof 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 beenclosed.Diagram 1Roof 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 2.44
