The gasvalve is situated on the right hand side of theunit and the gas inlet is on the right hand sideof the valve.Note: If the gas line is being installed fromthe left side, be sure to leave room toaccommodate servicing of the fan.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/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.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 2VERTICALTERMINATIONS1) Maintain the 1-1/2" (38mm) clearances(air spaces) to combustibles when passingthrough ceilings, walls, roofs, enclosures,attic rafter, or other nearby combustiblesurfaces. Do not pack air spaces withinsulation. Check pages 13-17 for themaximum vertical rise ofthe flueing system and themaximum horizontal offsetlimitations.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 flue will penetratethe ceiling. Drill a small holeat this point. Next, drop aplumb bob from the roofto the hole previouslydrilled in the ceiling, andmark the spot where theflue will penetrate theroof.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.Note: Apply sealant "Mill-Pac" to innerpipe and high temperature siliconesealant to outer pipe on every twist-lock joint.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" (38mm). Slip theflashing under the shingles (shingles shouldoverlap half the flashing) as per Diagram3.6) Continue to assemble pipe lengths.Note: If an offset is necessary in the atticto avoid obstructions, it is importantto support the flue pipe every 3'(0.9m), to avoid excessive stress onthe elbows, and possible separation.Wall straps are available for this pur-pose.Galvanized pipe is desirable above the rooflinedue to its higher corrosion resistance. Continueto add pipe sections through the flashing untilthe height of the flue 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 theflue height may solve the problem.7) Ensure flue 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 flue passes through must beenclosed.Diagram 1
