Crown Boiler BWC150/225 installation instructions 11a Joining Cuttable 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 bottom out on the collar (Figure 1.11b).

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 1.11a).

d)Use locking bands (provided with all fittings) to secure non-cuttable pipe, as well as fittings, to the boiler collar (Figure 1.11b).

e)Use the same method to join all remaining vent components except for the terminal.
