- Page 14 a) Determine the required length of the outer pipe. When doing this allow an additional 1” of length for insertion into the female end of the adjoining pipe. Mark the cut line on the outer pipe. b) Remove the plastic inner pipe by pulling it out from the female end. c) Cut the OUTER PIPE ONLY at the point marked in Step (a) using aviation shears, a hacksaw, or an abrasive wheel cutter.
- Page 15 Push the male end of the fi rst fi tting 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 fi ttings, the bead on the male pipe will bottom out on the collar (Figure 1.11b).
- Page 16 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 fi tting as shown in Figure 1.12a.
