F. CONNECTING FLEx OIL VENT PIPE TO APPLIANCE
ADAPTER AND DIRECT VENT TERMINATION
1. Flexible double wall oil vent pipe is available pre-cut
from 5 ft to 20 ft long. If necessary, the vent pipe may
be cut to required length with a hacksaw or cutoff saw.
CAUTION
Use safety glasses and other appropriated safety
gear when cutting the vent pipe.
2. The double wall flexible vent pipe consists of the smaller
inner corrugated stainless steel pipe and larger corrugated
aluminum pipe, separated by fiberglass insulation layer.
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 side to
be connected to the vent termination; secondly, at vent
pipe side to be connected to the appliance adapter. See
Figure 24.
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 24.
5. Slide supplied Cover Rings; firstly, over stop bead on
vent termination inner pipe; secondly, over stop bead on
appliance adapter. See Figure 24.
6. Remove any oil and grease from the end of vent termination
inner pipe, and, from the end of the 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 25.
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 25.
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 26.
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 26.
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).
