DIRECT VENT GAS FIREPLACE
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
11"(279mm) hole in the wall (inside
dimension).
Note: We recommend framing a
11"(279mm) x 11"(279mm)
(inside dimensions) hole to
give structural rigidity for
mounting the termination.
IMPORTANT: Maintain top, side and
bottom clearances around the pipe.
See specifi c unit installation manual
for proper clearances.
2) Level the fi replace and fasten it to
the framing using nails or screws
through the nailing strips.
3) Assemble the vent assembly by
applying Mill Pac to the 5"(27mm)
inner collar of the termination and
slipping the 5"(27mm) 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 8"(203mm) fl ex pipe and slip it
over the 8" outer collar of the vent
terminal at least 1-3/8"(35mm) and
fasten with the 3 screws.
NOTE: Horizontal sections must
be supported at intervals not
exceeding 3 feet (0.9 meter).
(Flame picture and perform-
ance will be affected by sags
in the liner).
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
918-211c502-
INSTALLATION PROCEDURES
for FPI Direct Vent System (Flex)
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) Attach the vinyl siding standoff
(mandatory for vinyl siding) to
the exterior wall. Ensure that the
holes in the standoff are positioned
at top/bottom to allow for proper
drainage. Note: If exterior wall is
not vinyl siding, read below.
Note: If installing termination on a
non-vinyl siding covered wall,
f u r r i n g
s t r i p s
must be
used to
e n s u r e
that the
termina-
tion is not
recessed
into the
siding.
6) Slip the assembled liner and ter-
mination assembly through the
thimble making sure the termina-
tion cap faces up (there are mark-
ings on the cap that show which
way is up). This will position the
Page 2 of 2
termination cap with proper down
slope for draining water. Fasten
the cap to the outer wall with the
4 supplied screws.
7) Pull the centre 5"(127mm) liner and
outer 8"(203mm) liner out enough
to slip over the fl ue collars of the
fi replace. (You may wish to cut
the liner shorter to make it more
workable.) Do not bend liner more
than 90
o
.
8) Apply Mill Pac over the fi replace
inner collar and slip the 5"(127mm)
liner down over it and attach with
3 supplied screws.
9) Do the same with the 8"(203mm)
liner.
10) Apply a bead of silicone between
the thimble and termination and
around the outer edge of the ter-
minal 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.
