These <br />instructions do not supersede local laws and regulations. Always <br />comply with local requirements. <br />FOR DOUBLE WALL INSTALLATION: <br />1). Locate penetration on the outside of the sump. Using a hole -saw of <br />the appropriate size, drill hole for penetration. On both the inside <br />and the outside of the sump arind an area that is at least 4" areaaterr <br />than the flat portion of the fiberalass cuff. h6ake sure the bonding <br />surface is clean and dry. If there is not enough room between <br />penetrations, the square base of the cuff can be trimmed so that <br />they do not overlap each other. <br />2). Ensure the bonding surfaces of the cuff pieces are sanded and <br />clean. Insert the smaller of the cuff pieces from the outside of the <br />sump through the hole so that the square base is as tight up against <br />the sump wall as possible, and centered in the hole. Use catalyzed <br />putty to immobilize the cuff. Seal and smooth the transition from <br />cuff to sump with a squeegee. If the fiberglass is not going to be <br />applied immediately, get the putty very smooth. If any bumps or <br />ridaes are present after the putty hardens they will have to be <br />sanded smooth to ensure a aood laminate. <br />3). Cut or tear pieces of fiberglass mat into 3" strips that are long <br />enough to extend past the corners of the cuff. You will need a <br />minimum of 16 pieces for each cuff (inside and out). <br />4). Use a piece of cardboard or other suitable surface to pre -wet the <br />fiberglass mat pieces, two layers at a time with catalyzed resin, <br />making sure to thoroughly saturate all the fibers. Place the mat <br />around the perimeter of the square base of the cuff, sealing all <br />edges and rollina out all of the air bubbles from the laminations. <br />Get the laminations as smooth and consistent in thickness as <br />possible. When the fiberglass has partially set up, it is possible to trim <br />any excess with a razor knife. If the surface of the laminate is good <br />and smooth, paint or "flow -coat" the entire surface with catalyzed <br />resin to further smooth out the fiberglass. <br />5). When the outer laminations have cured, center the larger of the <br />two cuff pieces over the cuff on the inside of the sump. Laminate <br />these pieces in the same manner as in step 4. <br />Page 19 of 38 <br />
