12
masonry chimney has an offset. If an offset
exists, then a section of Flex Pipe will be
needed to accommodate the offset.
B.
A Tee is installed at the bottom end of the
vertical pipe
(Figure 16)
.
C.
A Reduction Collar or a Trim Collar is
required to go around the pipe section that
passes through the masonry to give it a
finished look
(Figure 16)
.
3.
It will be necessary to break out the
masonry around the location of the pipe
center line mark to a diameter of at least 4"
for 3" pipe, and at least 5" in diameter for 4"
pipe.
4.
Install the Tee on the bottom of the vertical
pipe system and lower it down the chimney
until the center of the branch of the Tee
is level with the center of the hole in the
masonry. Connect horizontal pipe section to
the Tee branch.
5.
Holding the pipe at the proper elevation,
install the Storm Collar and Cap, as described
in
Step 11
for the fireplace installation.
6.
Connect the horizontal piece of pipe which
goes through the masonry to the Tee by
pushing it through the hole in the masonry,
and lining it up with the branch of the Tee.
Then push it into the Tee, while twisting to
lock it.
7.
Once the horizontal pipe section is in
place, the space between the pipe and the
masonry may be filled with high temperature
grout, as shown in
Figure 17
, if desired.
8.
Install the Reduction Collar or Trim Collar,
the 90° Elbow, and the vertical pipe section
going to the appliance. An Adjustable Pipe
length will probably be needed, as well as a
Pipe Adapter.
9.
Conduct a final inspection of the entire job,
and review the manufacturer’s operating and
installation instructions once more, before
firing the appliance.
