C. Assembly of Crown Concentric Venting WARNING Failure to follow the instructions could result in fl ue gas leakage into the combustion air or indoor air, resulting in unsafe or unreliable operation. • Do not lubricate concentric gaskets with anything other than water. • Do not attempt to cut any piping except as permitted in this section. When cutting these sections, make sure all cuts are square and allow for proper insertion. • Do not attempt to try to mix this concentric pipe wit

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. Be careful to cut the pipe square. De burr the cut end with a fi le or emery cloth. d) Make an insertion mar

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 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). c) The male end of cuttable fi ttings must be held to the col

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. c) Add 1-1/4” to distance “L”. Carefully mark this length on the pipe as shown in Figure 1.12b. d) Remove the aluminum inner pipe from the terminal, by gently pulling on it from the male end.

6) Vertical Terminal Installation - In addition to the vertical terminal, either a Flat Roof Flashing (80/125 PN 230533, 100/150 PN 230571) or Sloped Roof Flashing (80/125 PN 230535, 100/150 PN 230572) is required for this installation. a) Determine the center line of the terminal location on the roof. If the roof is fl at, cut a 5-1/2” diameter hole for the 80/125 terminal and a 6-1/2” diameter hole for the 100/150 terminal. If the roof is sloped, cut a hole large enough for the termi
