24 6) Use locking bands provided to join adjacent sections of non-cuttable pipe as well as fittings. The male end of the terminal section and other cuttable sections must be held to the female end of the adjoining pipe with at least three #10 x 1/2” sheet metal screws. Drill a 1/8 hole through both outer pipes to start this screw . Use a drill s[...]

T o cut the straight sections listed above refer to Figure 7.31 and the following instructions: 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 t[...]

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 ab[...]

4) 80/125mm Horizontal T erminal 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 len[...]
