c. Align collar plate clearance holes with rear/
bottom panel engagement holes; then secure the
collar to rear/bottom panel with six mounting
screws. See Figure 17.
d. Flue temperature sensor, factory attached to the
boiler wiring harness, is secured to the left boiler
jacket panel with tape.
e. Remove the tape and push the sensor rubber plug
into Concentric Vent Collar sensor port until the
plug is securely engaged. See Figure 17.
The installation of the Concentric Vent Collar is now
completed.

System Assembly
a. Plan venting system to avoid possible contact
with plumbing or electrical wires. Start at
vent connector at boiler and work towards vent
termination.
b. Do not exceed maximum Concentric vent length.
Refer to Table 12.
c. If additional concentric vent piping is needed:
i.
Concentric Vent Cut-To-Length Extension
pipes,
identified in Table 13 CAN BE
CUT
to required length when used as an
extension.
These pipes have plain male
end and beaded female end.
Always cut
the pipe from plain male end.
See Figure
18 ‘Cut-To-Length Extension (Cuttable)”.
d. To cut the Concentric Vent Straight pipe to
required length refer to Figure 20 “Cutting
Straight Pipe” and the following procedure:
i.
Determine the required length of the outer
pipe. When doing this allow an additional
1” of length for insertion into the female end
of the adjoining pipe. Mark the cut line on
the outer pipe.
ii.
Remove the plastic inner pipe by pulling it
out from the female end.
iii.
Cut the
OUTER PIPE ONLY
at the point
marked in Step (a) using aviation shears, a
hacksaw, or an abrasive wheel cutter. Be
careful to cut the pipe square. De-burr the
cut end with a file or emery cloth.
iv.
Make an insertion mark 1” from the male
end of the outer pipe.
v.
Cut the plastic inner pipe so that it will
protrude 3/8” beyond the male end of the
outer pipe when reinstalled in the outer pipe.
Use a fine tooth hacksaw or a PVC saw to
cut the plastic pipe and be careful to cut the
