Wallstraps are available for this purpose(Diagram 2).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 Diagram 5 orlocal codes. Note that for steep roof pitches, thevertical height must be increased.Diagram 3Note:For best results and optimum performancewith each approved venting system, it is highlyrecommended to apply “Mill-Pac” sealant toevery inner pipe connection. Failure to do somay result in drafting or performance issuesnot covered under warranty.UNIT INSTALLATION WITHVERTICALTERMINATION(Rigid Vent Systems)Note: A clearance of 2"(51mm) must bemaintained; except when passingthrough a wall, ceiling, or at thetermination where the use of a firestopor wall thimble reduces the requiredclearance to 1-1/2" (38mm). Werecommend framing a 11"(279mm) x11"(279mm) (inside dimensions) holeto give structural rigidity for mountingthe termination.1) Maintain the 1-1/2" (38mm)clearances (air spaces)t o c o m b u s t i b l e s w h e npassing through ceilings,walls, roofs, enclosures,attic rafter, or other nearbycombustible surfaces,ensuring that the use ofa firestop or wall thimbleis used as noted above.Do not pack air spaceswith insulation. Check"Venting Arrangement- Vertical Termination"section for the maximumvertical rise of the ventingsystem and the maximumh o r i z o n t a l o ff s e tlimitations.2) Set the gas appliancein its desired location.Drop a plumb bobdown from the ceilingto the position of theappliance flue exit,and mark the locationwhere the vent willpenetrate the ceiling.Drill a small hole athis point. Next, dropa plumb bob fromthe roof to the holepreviously drilled inthe ceiling, and mark the spot where the ventwill penetrate the roof. Determine if ceiling joists,roof rafters or other framing will obstruct theventing system. You may wish to relocate theappliance or to offset, as shown in Diagram 2to avoid cutting load bearing members.3) A Firestop spacer must be installed in the flooror ceiling of every level.4) Assemble the desired lengths of pipe and elbows.Ensure that all pipes and elbow connections arein the fully twist-locked position and sealed.Diagram 4: The upper half of the flashing isinstalled under the roofing material and notnailed down until the chimney is installed.This allows for small adjustments.5) Cut a hole in the roof centered on the smalldrilled hole placed in the roof in Step 2. The holeshould be of sufficient size to meet the minimumrequirements for clearance to combustibles of1-1/2"(38mm). Slip the flashing under the shingles(shingles should overlap half the flashing) as perDiagram 4.Offset ChartA poor draft, or down drafting can result from highwind conditions near big trees or adjoining rooflines, in these cases, increasing the vent heightmay solve the problem.7) Ensure vent is vertical and secure the base ofthe flashing to the roof with roofing rails, slidestorm collar over the pipe section and seal witha mastic.8) Install the vertical termination cap by twist-locking it.Note: Any closets or storage spaces, which thevent passes through must be enclosed.Diagram 5Roof PitchMinimum VentHeightFeet 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 2.44Diagram 2Diagram 1
