determine it’s structural condition.
2. Carefully read the pellet stove or insert
installation instructions.
3. Measure and record the dimensions as
shown in Figure 8.
4. Use dimension “A” to determine total pipe
requirements. Add 12 additional inches
to insure the termination is an adequate
distance above the rooine.
5. The gross pipe required will be “A”
dimension plus 12". Five feet of this will be
Flex Pipe. The remainder will be rigid pipe.
For each joint, subtract 1-1/ 2" to allow for
the overlap. You may need extra pipe, or an
adjustable length pipe section to achieve the
correct height.
6. Assemble the rst rigid pipe section to
the Flex Pipe, insuring that the “UP” arrows
shown on the pipe labels are, in fact, pointing
up. Push the sections together and twist to
lock. Screws are not required for a rm lock,
however, should it be desired to use them,
use stainless steel sheet metal screws 1/4"
long - DO NOT penetrate the inner liner of
the pipe.
7. Repeat this process for the remainder of
the pipe sections, and lower the assembly
down the chimney as shown in Figure 9.
Lower it below its normal position in order
to connect the Flex Pipe to the pipe on the
appliance. It may be necessary to tie a line to
the top section, to pull it back up later.
8. In making the connection at the appliance,
congurations other than the one shown in
Figure 10 may be made. It may be necessary
to contact the manufacturer of the unit to
determine exactly what may or may not be
done to make the correct connection. Some
typical arrangements are shown in Figures
11 and 12. A Pipe Adapter may be needed,
depending on the exit size of the stove or
insert collar.
9. If a Tee is necessary to make the
connection, as shown in Figure 12, the Tee
has a removable Clean Out Adapter on its
base to enable cleaning. The Tee Support
Bracket to hold the Tee to the rear of the
appliance is mandatory. If it is desired to
mount the Tee Support to the rear of the
stove, obtain approval from the manufacturer
of the stove before drilling, tapping, or
performing any other alterations to the
appliance.
10. Connect the appliance to the coupling
on the bottom of the Flex Pipe, by twisting
to the locked position. Push the appliance
into the replace to its nal resting place. Go
to the top of the chimney and pull the vent
system up to it’s desired height.
11. For the termination of the pellet vent,
you will use a Tall Cone Flashing, and a Storm
Collar. This will require 14" of pipe above the
top of the masonry chimney. Pull the pipe up
