Be careful to cut the pipe square. De burr the cut end with a file or emery cloth. d) Make an insertion mark 1” from the male end of the outer pipe. e) Cut the plastic inner pipe so that it will protrude 3/8” beyond the male end of the outer pipe when reinstalledin the outer pipe. Use a fine tooth hacksaw or a PVC saw to cut the plastic pipe and be careful to cut the pipe square. De burr the cut edge of the plastic pipe with a file, razor blade, or fine sandpaper. f) Reinstall the inner pipe. FIGURE 7.31: CUTTING STRAIGHT PIPE 27 3) Joining Pipe - a) Start assembly of the vent system at the boiler. Lubricate the brown gasket in the boiler vent collar with a few drops of water. b) Push the male end of the first fitting into the boiler collar until it bottoms out. The male end of cuttable sections should go 1” into the collar until the insertion mark (made in Step 2d above) is covered. On other fittings, the bead on the male pipe will be bottom out on the collar (Figure 32). c) The male end of cuttable fittings must be held to the collar with three #10 x 1/2” sheet metal screws. Drill a 1/8 hole through both outer pipes to start this screw. Use a drill stop or other means to ensure that the drill bit does not penetrate more than 3/8” into the outer pipe. Do not use a sheet metal screw longer than 1/2” (Figure 7.32a). d) Use locking bands (provided with all fittings) to secure non-cuttable pipe, as well as fittings, to the boiler collar (Figure 7.32b). e) Use the same method to join all remaining vent components except for the terminal. FIGURE 7.32a: JOINING CUTTABLE PIPE FIGURE 7.32b: JOINING NON CUTTABLE PIPE 28 4) 80/125mm Horizontal Terminal Installation - a) Cut a 5-1/2” diameter hole through the exterior wall at the planned location of the horizontal terminal. b) Measure distance “L” from the outside surface of the exterior wall to the end of the last fitting as shown in Figure 7.33a. c) Add 1-1/4” to distance “L”. Carefully mark this length on the pipe as shown in Figure 7.33b. d) Remove the plastic inner pipe from the terminal, by gently pulling on it from the male end. Set aside. e) Cut the outer pipe only at the point marked in Step (c) using aviation shears, a hacksaw, or an abrasive wheel cutter. Be careful to cut the pipe square. De-burr the cut end with a file or emory cloth. f) Reinstall the plastic inner pipe in the terminal, making sure that the female end of this pipe is completelybottomed out over the aluminum male connection visible behind the air intake grill. Place a mark on theplastic inner pipe 3/8” beyond the end of the outer pipe (Figure 7.33c). Use a fine tooth hacksaw or a PVC saw to cut the plastic pipe and be careful to cut the pipe square (if necessary, the plastic pipe can be removed from the terminal again for cutting). De-burr the cut edge of the plastic pipe with a file, razor blade, or fine sandpaper. g) Make a mark on the terminal section 1” from the cut end of the outer pipe as shown in Figure 7.33c. h) Slip the terminal section through the wall from the outside. Pass the terminal through the inner wall plateand push into the last section of vent pipe until the mark made in Step (h) is not longer visible (Figure7.33d). Secure the terminal to the last piece of pipe with three #10 x 1/2” sheet metal screws. Drill a 1/8hole through both outer pipes to start these screws. Use a drill stop or other means to ensure that the drill bit does not penetrate more than 3/8” into the outer pipe. Do not use a sheet metal screw longerthan 1/2”. i) Slip the outer wall plate over the terminal and secure to the wall (Figure 7.33d). Apply a 1/8” bead of weather resistant RTV over the joint between the outside wall plate and the terminal. Secure the other wall plate to the inside wall.

These gaskets prevent infitration of rain water into the air intake section. Do not interchange with similar componentsshown in Table 7.4b. a) Cut a 6” diameter hole through the exterior wall at the planned exit point of the vent. A minimum of 4” is needed between the center line of this hole and grade to install the lower wall bracket. b) Before mounting the lower wall bracket, loosen the M10 x 35 screw on this bracket. Adjust this bolt forwa...
