INSTALLATION
4)
Separate the 2 halves of the wall thimble
and securely fasten the one with the tabs to
the outside wall making sure that the tabs
are on top and bottom. Fasten the other
thimble half to the inside wall. The thimble
halves slip inside each other and can be
adjusted for 2 x 4 or 2 x 6 walls.
The liners
must slip over the collars a minimum of
1-3/8".
5)
Slip the assembled liner and termination
assembly through the thimble making sure
the termination cap faces up (there are
markings on the cap that show which way
is up). This will position the termination cap
with proper down slope for draining water.
Fasten the cap to the outer wall with the 4
supplied screws.
6)
Pull the centre 4"(100mm) liner and outer
6-7/8"(175mm) liner out enough to slip
over the flue collars of the fireplace. (You
may wish to cut the liner shorter to make
it more workable.) Do not bend liner more
than 90
o
.
7)
Apply Mill Pac over the fireplace inner collar
and slip the 4"(100mm) liner down over it
and attach with 3 supplied screws.
8)
Do the same with the 6-7/8"(175mm)
liner.
9)
Apply a bead of silicone between the thimble
and termination and around the outer edge
of the terminal at the wall in order to keep
the water out.
IMPORTANT:
Do not locate termination
hood where excessive snow or ice buildup
may occur. Be sure to check vent termi-
nation area after snow falls, and clear to
prevent accidental blockage of venting
system. When using snow blowers, make
sure snow is not directed towards vent
termination area.
Note: To make the
installation more
aesthetically pleas-
ing, we recommend
framing out a square
to mount the termi-
nal to.

INSTALLATION
PROCEDURES
for FPI Direct Vent
System (Flex)
1)
Locate the unit in the framing, rough in the
gas (preferably on the right side of the unit)
and the electrical (Junction block is on the
left side) on the left. Locate the centerline of
the termination and mark wall accordingly.
Cut a 10"(254mm) hole in the wall (inside
dimension).
Note: A 1-1/2"(38mm) clearance around
the liner must be maintained except
that only a 1" (25mm) clearance is
needed at the termination end. We
recommend framing a 10"(254mm)
x 10"(254mm) (inside dimensions)
hole to give structural rigidity for
mounting the termination.
Note: If installing termination on a siding
covered wall, furring strips must be
used to ensure that the termination
is not recessed into the siding.
2)
Level the fireplace and fasten it to the fram-
ing using nails or screws through the nailing
strips.
3)
Assemble the vent assembly by applying
Mill Pac to the 4"(100mm) inner collar of the
termination and slipping the 4"(100mm) liner
over it at least 1-3/8" (35mm). Fasten with
the 3 screws (drilling pilot holes will make this
easier). Apply Mill Pac or high temperature
silicone to the 6-7/8"(175mm) flex pipe and
slip it over the 6-7/8" outer collar of the vent
terminal at least 1-3/8"(35mm) and fasten
with the 3 screws.
NOTE: Horizontal sections must be sup-
ported at intervals not exceeding 3
feet (0.9 meter). (Flame picture and
performance will be affected by sags
in the liner).
increased. A poor draft, or down drafting can
result from high wind conditions near big trees
or adjoining roof lines, in these cases, increas-
ing the vent height may solve the problem.
7)
Ensure vent is vertical and secure the base
of the flashing to the roof with roofing rails,
slide storm collar over the pipe section and
seal with a mastic.
8)
Install the vertical termination cap by twist-
locking it.
Note: Any closets or storage spaces, which
the vent passes through must be
enclosed.
