iii.
The male end of cuttable fittings must be held
to the collar with three (3) #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”
(see Figure 23).

Use locking bands (provided with all fittings)
to secure non-cuttable pipe, as well as fittings,
to the boiler collar (see Figure 23).
v.
Use the same method to join all remaining vent
components except for the terminal.
