Regency ® P36-4 Gas Log Fireplace18Offset ChartGalvanized 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 Diagram 5 orlocal codes. Note that for steep roof pitches,the vertical height must be increased. A poordraft, or down drafting can result from highwind conditions near big trees or adjoiningroof lines, in these cases, increasing the flueheight 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 3Diagram 5Diagram 1Diagram 2Note: Apply sealant "Mill-Pac" to innerpipe and high temperature siliconesealant to outer pipe on every twist-lock joint.VERTICALTERMINATIONS1) M a i n t a i n t h e 1 - 1 / 4 "clearances (air spaces)to combustibles whenpassing through ceilings,walls, roofs, enclosures,attic rafter, or other nearbycombustible surfaces.Do not pack air spaceswith insulation. Checksection "Simpson Dura-vent Flueing" for themaximum vertical rise ofthe flueing system and themaximum horizontal offsetlimitations.2) Set the gas appliance in its desired location.Drop a plumb bob down from the ceiling to theposition of the appliance flue exit, and markthe location where the flue will penetratethe ceiling. Drilla small hole athis point. Next,drop a plumbbob from theroof to the holepreviously drilledin the ceiling,and mark thes p o t w h e r et h e f l u e w i l lpenetrate theroof. Determineif ceiling joists,roof rafters orother framing3) 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 3 and install thefirestop.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".

Youmay wish to relocate the appliance or tooffset, as shown in Diagram 2 to avoid cuttingload bearing members.INSTALLATION
