4) Installation of this kit will require an opening at the base of the chimney (at the level of the horizontal vent connection) that is approximately 7” wide and 12” tall. A slightly smaller, or significantly larger opening may be required depending on the chimney wall thickness. Before attempting to install this kit, make sure that such an opening either exists, or can be made, without compromising the structural integrity of the chimney (much of this opening will be re-closed later in the installation process). 5) Maximum distance from center of chimney chase to outside surface of chimney base is 23” (Figure 1.2). 6) Verify that there are no offsets in the chimney that will cause the PPs Flex Liner to bend more than 45 degrees. 7) Verify that it will be possible to maintain a 5/8in per ft. pitch towards the boiler in all horizontal piping between the boiler and the elbow at the base of the chimney chase. 8) PPs Flex Liner and the hardware needed for a single PPs Flex Liner installation are sold separately. All hardware is included in a “PPs Flex Installation kit”. Table 1.1 shows the Crown part numbers for these kits and the PPs Flex Liner itself. 10 6) Remove the rope or pull tool from the end of the vent. 7) Verify that the Male Adaptor is undamaged. Lubricate the brown gasket in the female end of the Elbow with a few drops of water and insert the Male Adaptor fully into the Elbow. 8) Mount the bottom end of the PPs Flex Liner with the Elbow onto the Elbow Support Bracket installed in Step #2 using the Male Adapter Clamp as shown in Figure 1.9. 9) The cap provided with this kit is designed for installation over chimney crowns with round openings up to 12” and square openings having inside dimensions up to 8-1/2”. If the opening in the crown is larger than this, the installer must provide a weather tight crown with an opening below these limits. The minimum diameter of the opening in this crown must be 6” for the 80mm PPs Flex Liner and 7” for 100mm PPs Flex Liner. Make such modifications to the crown in accordance with standard practice before proceeding further. 10) Cut the top end of the PPs Flex Liner so that it protrudes between 1-3/4” and 2-1/4” above the top surface of the crown (Figure 2.0). Cut the pipe in one of the grooves using a sharp utility knife. 11) Install the Female Adaptor on the top end of the PPs Flex Liner using the same technique used to attach the Male Adaptor (Figure 1.7). Allow the Female Adaptor to rest on Support Cross. 12) Apply a bead of weather resistant caulk or mortar to the crown and set the Lower Vent Cap flange on the crown so that the joint between the Lower Vent Cap flange and the crown is completely air and water tight. Anchor the Lower Vent Cap Flange to the crown using an appropriate fastener through the knock-out in each corner. 13) Moisten the brown gasket in top of the Female Adaptor with a small amount of water and fully insert the Stainless Termination Pipe. 14) Slide the Upper Vent Cap over the Stainless Termination Pipe and snap in place on the Lower Cap. 15) Provide a thimble for the penetration into the bottom of the chimney chase. This can be a section of smoke pipe, duct or ceramic chimney tile. It must be installed so that the following requirements are met (Figure 2.1): • The inside dimensions of this thimble must meet the minimum chase ID requirements shown in Table 1.1. • The thimble must be located so that a 5/8” in per ft. pitch can be maintained in the Vent Stub between the Elbow and Concentric Adaptor. • The thimble must be sealed to both the chimney flue and the exterior surface of the chimney using mortar or other suitable sealant having a service temperature rating of at least 210F. • The thimble must not protrude into the original chimney flue. 16) Lubricate the gasket in the female end of the Vent Stub with a few drops of water and push it onto the Elbow. 17) Mount the Exterior Wall Plate so that the Vent Stub will pass through the center of the opening in this plate when properly pitched. Anchor the Exterior Wall Plate to the wall using four masonry anchors, or other appropriate fasteners, capable of supporting at least 40lbs each. Note: Exterior Wall plate must completely cover the thimble. Exterior Wall Plate can be cut down as long as this condition is met. If the flange on the Concentric Adaptor is large enough to cover the thimble, the exterior wall plate may be omitted completely. If the Exterior Wall Plate is too small to cover the thimble, a larger plate may be fabricated in the field using 18GA (or heavier) galvanized steel. If the exterior wall plate is cut down or replaced, the Usage Warning Label on the plate must be saved and attached to the base of the chimney near the concentric adaptor. 18) Seal the Exterior Wall Plate (if used) to the outer wall of the chimney using a suitable sealant having a service temperature rating of at least 210F. 19) Mark the Vent stub at a point 1” beyond where it exits the Exterior Wall Plate (F...
