Hearth and Home Technologies OXDV30SP Installation And Operating Instructions Manual page 16

For DuraVent pipe only: Install vent pipe by aligning the
locking system together, sliding the pipes together and
twisting clockwise.
• Install 90° elbow. Twist lock as before.
• Slide the wall plate over horizontal run before
attaching the horizontal run to the elbow. Fasten wall
plate to wall.
4. For Hearth & Home Technologies Vent Pipe only: If
necessary, measure to determine the vertical length (X)
of pipe required from the adapter pipe to the wall cutout
centerline, including a 2" (51mm) overlap at the joint.
(Figure 24) use a hacksaw or tin snips to trim the pipe as
needed.
Figure 24 - Determine the vertical pipe length.
5. Install first the inner then the outer straight pipe section(s),
trimmed end down, to the point of the elbow. Drill 3 holes
through each joint and fasten with sheet metal screws.
6. Seal and install the elbow using 3 sheet metal screws at
each joint.
7. Measure, and cut if needed, the appropriate length of
pipe section needed to make the connection through
the wall. Include a 2" overlap; i.e. from the elbow to the
outside wall face, about 2" or the distance required if
installing a second 90° elbow. (Figure 25)
8. Slip the wall plate and trim collar over the interior end of
the horizontal pipe and install into the wall sleeve. Seal
the joint inside the wall plate if needed to keep cold air
from being drawn into the home.
9. Seal the ends and connect the horizontal pipe to the
elbow. Fasten the wall plate to the pipe with three sheet
metal screws. Slide the trim collar up against the wall
plate to cover the screws. (Figure 26)

Double check that the vent pipes overlap the collars by
2". Fasten the termination to the wall with the screws
provided, and caulk the joint with weatherproof sealant.
