IV. Venting (continued)
Figure 22: Cutting Vent Terminal Pipe
CAUTION
Exterior wall surface must be reasonably at to
attach the Outside Wall Plate. When exterior wall
surface is not at (covered with vinyl or wood
shingle siding etc.) the siding must be removed,
and a at surface build up ash or above siding
exterior surface to secure/seal the terminal
Outside Wall Plate.
•. Install the supplied Inside W
all Plate onto
the shortened Horizontal (Wall) Terminal
interior end and move the plate to cover
interior wall cut opening. Secure the plate
with provided fasteners, then, apply the
sealant around plate sides to seal it to
interior wall (refer to Figure 23).
• Lubricate the brown gasket inside boiler
concentric vent collar or the last section of
the vent pipe with small amount of water.
• Ensure that inner pipe of the terminal is
evenly engaged into the gasket all around,
then push the termination male end inside
boiler concentric vent collar or the last
section of the vent pipe, until the mark (see
Step v) is no longer visible.
• Re-install locking band clamp onto the
joint to secure the terminal to the collar or
the last section of the vent pipe.

Vertical Vent Termination
a. Standard Concentric Termination
Refer to Figures 24 thru 28.
i. In addition to the vertical terminal, either a
Flat Roof Flashing or Sloped Roof Flashing
is required for this installation. Refer to
Table 10 ‘Concentric Vent Components’ for
details.
• Determine the centerline of the terminal
location on the roof. For at roof, cut
5½” diameter hole (80/125 mm concentric
vent size) or 6½” (100/150 mm) for the
terminal. For sloped roof, cut a hole in the
roof large enough for the terminal to pass
through the roof while remaining plumb.
CAUTION
If the boiler is located directly under the hole,
cover it while cutting the hole to prevent debris
from falling onto boiler.
