4. Horizontal Vent Termination
a. Standard Concentric Termination
Refer to Figure 24.
i. Permitted terminals for horizontal venting:
Horizontal (Wall) Terminal, [80/125 mm
(P/N 101808-01), 100/150 mm
(P/N 101809-01] - see Table 15.
ii. Concentric Vent components supplied with
the boiler are packed inside boiler carton and
include the following:
• Horizontal (Wall) Terminal,
• Horizontal (Wall) Terminal consists of
Straight section having plain male end with
locking band clamp installed; Terminal
Assembly with offset vent termination,
and Outside Wall Plate, both riveted
on the opposite end; overall length is
approximately 28-1/8”.
• Separate Inside Wall Plate
• Two Hardware Bags (each bag contains
four screws and four anchors) to attach vent
terminal Outside Wall Plate to exterior wall
and Inside Wall Plate to interior wall.
iii. For horizontal (sidewall) installation, the
Horizontal (Wall) Terminal will extend past
outer wall surface by 4¼” (80/125 mm) or
5½” (100/150 mm). See Figure 24 “Horizontal
Concentric Venting”.
iv. Install the Horizontal (Wall) Terminal:
• Cut a 5½” diameter hole through the exterior
wall opening (for 80/125 mm concentric
vent) or 6½” (for 100/150 mm) at the planned
location of the horizontal terminal.
• Measure dimension “L” from exterior wall
outer surface to the end of the last tting.
See Figure 25 ‘Dimension “L”’.
• When factory Horizontal (Wall) Terminal
needs to be shortened, measure dimension
“L” plus 1¼” from inside of the attached
Outside Wall Plate and mark the Horizontal
(Wall) Terminal outer pipe. To achieve a
square cut of the outer pipe, place several
marks around the outer pipe to establish a cut
line. See Figure 26 ‘ Cutting Vent Terminal
Pipe’.
• Carefully cut the outer pipe at the marked
line using aviation shears, a hacksaw etc.
Ensure the pipe is cut square and cut end is
de-burred.
• Mark the end of the Horizontal (Wall)
Terminal inner polypropylene vent pipe to
extend 3/8” past the cut end of the outer pipe.
To achieve a square cut of the inner pipe,
place several marks around the inner pipe
to establish a cut line.
• Cut off the marked end of inner polypropylene
vent pipe with a ne tooth blade hacksaw
etc. and de-burr. See Figure 26 “Cutting Vent
Terminal Pipe.
This pipe can be removed from the terminal
to ease cutting, if desired.
