30 | Regency HZ33CE-10 Gas Fireplace|30installationGAS LINEINSTALLATIONThe gas line is brought through the right side ofthe appliance. The gas valve is situated on theright hand side of the unit and the gas inlet is onthe right hand side of the valve.The gas line connection may be made of rigidpipe, copper pipe or an approved flex connector.(If you are using rigid pipe, ensure that the valvecan be removed for servicing.) Since somemunicipalities have additional local codes it isalways best to consult with your local authoritiesand the CAN/CGA B149 installation code.For USA installations follow local codes and/or thecurrent National Fuel Gas Code, ANSI Z223.1.When using copper or flex connectors use onlyapproved fittings. Always provide a union so thatgas lines can be easily disconnected for servicing.Flare nuts for copper lines and flex connectorsare usually considered to meet this requirement.Important: Always check for gas leaks with asoap and water solution or gas leak detector.Do not use open flame for leak testing.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 venting systemand the maximum horizontaloffset 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 penetrate theceiling. Drill a small hole at thispoint. Next, drop a plumbbob from the roof to thehole previously drilled inthe 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.4. Assemble the desired lengths of pipe andDiagram 4NOTE: For best results and optimumperformance with each approved ventingsystem, it is highly recommended to apply“Mill-Pac” sealant (supplied) to every innerpipe connection. Failure to do so may resultin drafting or performance issues not coveredunder warranty.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..elbows. 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 roof linedue 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
