CAUTION
The inner and outer pipe ends may have sharp
burrs. Use gloves, while handling, compressing
or expanding the vent pipe.
3. Pull outer vent pipe back 1” to 2” from end of inner
vent pipe and remove insulation; firstly, at vent
pipe end to be connected to the vent termination;
secondly, at vent pipe end to be connected to the
appliance adapter. See Figure 22.
4. Install supplied Cover Sleeve Assembly onto each
end of outer vent pipe, and, move the assembly
a few inches back from the end; firstly, at vent
pipe side to be connected to the vent termination;
secondly, at vent pipe side to be connected to the
appliance (boiler outlet collar) adapter. See Figure
22.
5. Slide supplied Cover Rings; firstly, over stop bead
on vent termination inner pipe; secondly, over stop
bead on appliance adapter. See Figure 22.
6. Remove any oil and grease from the end of vent
termination inner pipe, and, from the end of the
appliance adapter.

Inner Pipe and Appliance Adapter
7. Apply sealant; firstly, between the stop bead and
retainer bead at the end of the vent termination inner
pipe; secondly, between the stop bead and retainer
bead at the end of the appliance adapter. See Figure
23.
8. Assemble supplied inner pipe clamp halves with
1/4-20 bolts and square nuts; position the inner pipe
clamps ¼” from the end of inner vent pipe, on vent
pipe opposite ends.
9. Remove any oil and grease from inside of each end
of the inner vent pipe.
10. Apply a thick bead of sealant to inside of each end
of the inner vent pipe, ½” from pipe end, working
the sealant into the inner vent pipe corrugations. See
Figure 23.
11. Firstly, push one end of the inner vent pipe onto the
vent termination inner pipe, all the way up to the
stop bead. Secondly, push the opposite end of the
inner vent pipe onto the appliance adapter, all the
way up to the stop bead.
12. Tighten the inner pipe clamp bolts at both vent pipe
ends, until clamp halves are within 1/8” apart. See
Figure 24.
13. Starting with vent termination end, slide the cover
sleeve assembly and the cover ring together to
engage the ring in the groove of the sleeve, then,
tighten the built-in cover sleeve clamp. Repeat above
steps at the boiler end. See Figure 24.
14. If the appliance collar is within less than 18" of
combustible material, wrap minimum 1-1/2" thick
fiberglass insulation (installer provided).
15. To maintain vent pipe 1" clearance to combustible
material, wrap minimum 1-1/2" thick fiberglass
insulation (installer provided) around the exposed
portion of the vent termination inner pipe and secure
with adhesive-backed aluminum foil tape (installer
provided).
